Floor Sealing & Maintenance

In domestic environments, 2 or 3 coats of lacquer/oil are standard, depending upon the products, type of surface and the level of footfall. Additional coats can be applied upon request or may be recommended and will be charged for accordingly in addition to the original quotation.

Lacquer longevity is dependent on traffic, conditions and maintenance procedures used by you, our customer.

We recommend maintaining your floor with professional maintenance products only. It is agreed that U.K. Floor Sanding accepts no responsibility or liability of any floor, for the ongoing maintenance of the floor unless a maintenance contract is undertaken with U.K. Floor Sanding.

Professional maintenance products and a maintenance program is available from U.K. Floor Sanding, please go to 'BUY SUPPLIES ONLINE'


ONLINE-MAINTENANCE. Please enquire at the telephone number shown at the bottom of this page, for more information. The frequency of maintenance is dependent upon certain factors and you will be advised accordingly. A book is available online or in hard copy form free of charge to all U.K. Floor Sanding customers.

Lacquers are generally touch dry in 1-3 hours, oils in 8 hours. It is the client's responsibility to make arrangements as necessary to avoid contact with lacquers whilst drying and during curing time. It is the customer's responsibility to ensure that adequate ventilation is created and is possible whilst works take place as we cannot be held responsible for inadequate ventilation or any damage to items or persons or pets or animals as a result of. In the event that solvent based products are used, then this will increase the fume level and whilst in principle, this should dissipate following the approximate 1 hour drying time, the fumes can be still present a long as the following day or longer. We do ask that as much ventilation is allowed in this event and appropriate steps taken by you. If, as a result of poor sealing or compromise by way of cracked or unsealed brickwork, cavity or chimney breast/flu or otherwise to adjoining properties, causes the smell to travel to another property, then we cannot be held responsible for the integrity or lack of integrity of the structure of your building and more-so, we would suggest that you consult a structural engineer to inspect the property as similarly, fumes from an accidental fire would affect your neighbours. In the event that such a situation does occur, we accept no liability whatsoever for any damages incurred as a result of, either to yourselves as our customer or to any neighbouring property. If the customer wishes to be present at the property, then they should position themselves away from the work environment. Your manager on-site will be happy to answer any questions you have and we kindly ask that these questions are grouped at the start, mid or end of the day as frequent questions throughout the day can sometimes distract our workers from the job in hand and potentially compromise or delay your work. Every reasonable effort will be made to complete the works on time , however because of the nature of the work and the numerous potential varying factors that can affect the efficiency of the work, we cannot guarantee work will be completed as originally advised - we hope you appreciate this and would please ask not to hesitate to ask your manager should anything urgent arise or alternatively, please call our offices. No liability whatsoever will be accepted in regard to the customer, or their friends or relatives being affected at all by the work process. It is also the customers responsibility to make arrangements with children and/or pets to be removed from the work area and surrounding areas, whilst the works take place and if required, following works whilst the evaporation process takes place. Please do not ask our workers to 'pet-sit' or 'baby-sit' or look after the welfare of any animal, pet, family member or person as we strictly cannot accept responsibility for any loss as a result of failing to do so. If we have to return to the site after completion date to continue with remedial works or to carry out any correctional work, then the same conditions apply as above. Any correctional work required must be reported to us in writing within 7 days of the original completion date of the work. In this event, it is agreed that the customer(s) allows a representative of our company visit and re-enter the property to fully inspect the floor, view and assess any issues claimed. Once all issues have been reviewed and consideration given in this regard, if accepted, we should be allowed to carry out the remedial works and the customer should make suitable and reasonable arrangements for this to be made possible within a period of 30 days from the original completion date of the work. In the event that the area is not accessible within this period, then the full payment due is to be made on completion of works whilst we await the pending re-works date. It is the client's responsibility to remove all items/property of value from the work area and vicinity. Clients are ultimately responsible for items left within the property. This includes rooms we are working in and any adjoining areas.

Whilst U.K. Floor Sanding will aim for 100% satisfaction, however hand applied seals may not show complete uniformity. Recoating at client's request is chargeable.

Lacquers require 3-7 days for full curing to take place. Care should be taken when replacing furniture prior to this time. U.K. Floor Sanding cannot be held liable for marking to floors after any work is complete, (or during works if these marks are not caused by ourselves) although, at our discretion, we may offer to assist in resolving any (non-fault - U.K. Floor Sanding) issues either by additional charge or, depending on the amount of work involved, by not charging. Please note: Any works carried out under this arrangement is strictly at our discretion.

U.K. Floor Sanding reserves the right to change job specification as necessary in order to provide the most appropriate finish for floor.

The Floor Sanding Process

It is the client's responsibility to ensure rooms are completely empty of furniture and other tradesmen at the start of work. The moving of furniture before, during or after the work is not included in your price. We can however in certain circumstances move furniture if arranged prior to works commencing. A charge will be made for this service - please enquire to confirm costs and at least 7 days before the work commences if required. In the event that furniture is not removed from site by the customer, then no liability whatsoever will be accepted as a result of any damage whatsoever that is caused to the furniture or furnishings. Any time over and above 15 minutes for room preparation and/or furniture removal will be charged accordingly in addition to the price that you have been quoted.

If rooms are not left empty, U.K. Floor Sanding cannot be held liable for any damage that occurs during removal of furniture. Our sanding process is usually between 95%-100% dust free. However, in certain circumstances, additional amounts of dust will be produced where we have to use hand sanding or make repairs or when the specific nature of the work demands a more brutal approach and a more coarse abrasive than usual approach is required. We are continually commended for our tidyness and lack of dust and whilst this may be the case, the removal of bitumen or paint or other residual products present on the floor can create increased levels of dust or vapour. Therefore, increased levels of dust could be created in this instance and you, the customer are required to be accepting of this possibility. This applies not only to the room in which the work is being carried out, but also to any adjacent room(s) that could be affected by it. We are not insured to cover this and cannot accept responsibility for this, therefore, you should remove any items of value that may be potentially affected by this.

Although due care and diligence will be exercised by U.K. Floor Sanding, due to nature of machine work and the requirement to sometimes angle the machinery in accordance with the floor levels, decoration and skirting may be liable to marking.

U.K. Floor Sanding cannot be held liable for marking nor the cost of redecoration. In the interests of creating a uniform finish, floors may require sanding more in some areas than others and this is usually due to changes in the level of wear, staining or some form of residual product or scratch that is required to be sanded. Whilst every effort is made to sand a minimum amount from the surface of the floor, no liability can be accepted should floor levels alter or undulate or the amount of wood sanded alter as a result of carrying out this procedure. Every effort will be made to improve any errors or improve what we consider to be lower standards of sanding that have been created previously by other 3rd party floor sanding companies. It may not necessarily be practical to notify you of these improvements as it is usually more efficient to carry out the improvement instantly whilst carrying out the general floor sanding works at that time. Anything that requires an amount of time which will involve an additional cost will require us to notify you of this prior to carrying out the work. If you are not available to be notified at that immediate time, then the improvement in question may not be completed. It is not always possible to improve the errors of other floor sanding works completely and on this basis in no way do we accept that we have inherited the error or the lower standard of sanding that has created the situation where we attempt to improve it. It is agreed that sufficient wood surface is supplied to us to carry out our works and that we are not held responsible for any shortfall in this regard i.e. end of sand/maintenance cycles. This also applies even if we are asked to carry out ongoing maintenance of a floor. It is agreed that we are not responsible for any resulting condition on an aged floor sub-structure (as in, not new). It is agreed that if repair work is carried out and new or reclaimed flooring is fitted, then we cannot guarantee the resulting colour of the wood when it is varnished. In the same, we cannot guarantee an exact match in wood type or size. Please also note that different fixing methods are likely to be used opposed to aged traditional methods and as a result there can be variants in the movement/settlement of the floor at a later time.

Our Hours of Work

Where possible, our hours of work on site, are usually, 8am-4pm, Monday to Friday. (Office Hours 8am - 5.30pm Mon - Fri. However, work can be undertaken outside of these hours by prior arrangement. The exact times required to carry out works cannot be determined as each floor is individual and the levels of contamination present in a pre-existing floor cannot be determined until such a time that the work is carried out. For example, it may not be evident until such a time when the floor has reached a certain stage of sanding, that additional sanding is required to remove unforeseen staining. Whilst, in most cases we do not alter our agreed price, more time is often required to undertake this additional work and therefore provisions should be made and allowed for, should this situation transpire. Seldom does this happen however, if this situation creates excessive periods of time, we may ask for additional cost to cover the stain removal - we will discuss this with you and request your approval before continuing with the stain removal, should this happen.

Wooden Floor Gap Filling

We can guarantee that we use specific wood floor filling products, that are recognised and established within the industry, and that no P.V.A. or glue mixes are used to satisfy this process. In certain circumstances however, and due to the sometimes extensive natural movement of wood, the deterioration of wood, compromises in the previous fitting of the wood, the general quality and consistency of the wood and natural movement of a sub-floor, the filling itself cannot be guaranteed and can fail at any time. This is more likely to happen when the timber tongue & groove has been compromised, or if the timber is plank and not a tongue & groove design or in the event that a void or a possibility that air pockets are present beneath the wood. This becomes evident when refills are carried out and the voids or air pockets cause the filler to continually seep through. This is a compromise in the substrate and/or the pre-existing wood and is not the responsibility of U.K. Floor Sanding. We will however undertake to refill where necessary (spot fill) up to 3 times to help establish this, after which any fall through or seep through will be deemed as an inappropriate substrate of which we will not be held responsible for. Full payment would be required in the event of this occurring at the time of the work or in the unlikely event of any time later.

Floor Sanding & Repairs

Minor repairs will be made as necessary to make a good floor surface unless otherwise instructed by you, our customer. Sub-structure repairs will only be made upon instruction by you, our customer. It is the customer's responsibility to supply a floor that is fit for purpose and fit for the sanding work requested to us. It is the customers responsibility to ensure the floor is suitable for the work to be carried out upon and safe to do so. Any injury in this regard due to an unreasonable level of safety that results in injury to our workforce may be claimed via the customers insurers. The floor should be fit for the purposes of sanding. Any floor that appears to be wood that later is found not to be wood as a result of the sanding of it cannot be adversely claimed against U.K. Floor Sanding. It is agreed that U.K. Floor Sanding will not be held responsible for not identifying that a floor that appears to be wood is in fact NOT wood or is a veneered or laminated version of wood. Similarly, it is also agreed that the remaining 'life' of a floor or the degree of wood remaining on the floor in order for it to be sanded is not our responsibility and no liability will be accepted in this regard. This is particularly important in aged floors where we would be unable to determine the sanding works taken place previously and the levels/depths of wood remaining on the surface. Whilst every effort is made to improve the look of the wood, we are not responsible for any existing imperfections on the floor or in the wood. These imperfections may not be noticeable until a time after the floor has been sanded or after it has been varnished. It is agreed that the quality, soundness and/or integrity of the wood is not our responsibility. Cancellation of work on finding any imperfections will still incur the originally agreed charge or the originally agreed charge less the material cost element not used.

An estimate of any repair costs can, upon request, be made prior to undertaking work. This is estimated on an hourly basis and an estimation of hours can be given but not guaranteed. Actual total cost of repair is only available when repairs have been completed. All repairs are recorded on job sheet. The rate given is based on a rate per man, per hour, with a minimum of 1 working hour. Repairs taking up to 15 minutes will not be charged for. Works may be delayed or cancelled if such paid repairs are not agreed by the time of carrying out the works. It is accepted that no liability or damages are the responsibility of U.K. Floor Sanding as a result of any delays or cancellations in this regard.

Supply of reclaimed timber is in accordance with market availability. Sourcing the timber is charged at £30 per hour per person and therefore we usually advise that you the customer, source any timber that is required. In the event that we source the timber, it is usually ordered by us online and whilst this may prove to be more cost effective for you, the same degree of checking is not implemented and as the timber is obviously reclaimed, we cannot guarantee that all sections of the timber will be considered appropriate or in good order, so some waste should be expected and the cost of this accounted for. Any additional timber required because of this or because of excessive wastage will be the responsibility of you, the customer. To avoid this, we strongly recommend that you source your own timber to help eliminate this possibility, should this situation transpire and likely to become problematic in any way.

Reclaimed timber cannot be guaranteed to be the same colour as existing timber.

Wooden Floor Colouring

All colour samples are representative and may vary due to individual conditions.

Once a colour has been agreed, verbally or otherwise, any changes will be chargeable at full job rate.

It is the client's responsibility to check colour at moment of application.

Re-colouring will be chargeable at full job rate.

Samples can be provided and agreed beforehand. However, if client is not present at time of application, subsequent alterations will still be charged at full job rate.

When applying colouring (or stain), it has to be applied at a certain speed and flow - this avoids over-build of colour and enables us to maintain consistency. The floor area is considered to be the area where any footfall can occur. Gaps beneath skirting boards where the floor proceeds is not deemed as floor area as is any other area that limits the accessibility to those areas (i.e. low level shelves, low level radiators, low level units etc.) and whilst we will endeavour to reach these areas with colour, there is no guarantee that this will be satisfied with any degree of consistency or reached at all. Our objective is to sand and/or colour every area required and we will do our utmost to satisfy this wherever these areas are accessible. Where there are gaps beneath skirting boards, these areas are not always accessible or at least not accessible at the 'flow rate' required to maintain a consistent volume of colour or stain. Time spent attempting to acces these areas can compromise the consistency of colour on the main floor and these areas therefore may not be reasonably accessible. As a result, these areas are not considered as being a reasonably accessible area of the floor and may need to missed from the colouring process. However, in an attempt to cover all areas beneath the skirting boards at the flow rate required, we may be required to 'push' the colour into the corner and in doing so may be mark the skirting board during colouring. In the event that this happens, allowances should be made for this as U.K. Floor Sanding cannot be held liable for marking or redecoration. Complete uniformity is not guaranteed when hand colouring and finishing a floor. Matching colours cannot be guaranteed nor can the eventual shade, tone, depth or variant as this will differ based upon the type, age, condition, humidity level and area of the tree from where the wood relates to.

Electrical Supply

Sanding machinery requires 240v in ready supply although we will use RCD breakers where required. It is the client's responsibility to ensure their power supply is in safe, good and appropriate condition to undertake the work. Please ensure that the power points are regularly situated within the room that we are working on. The maximum length of our cables is limited to 25 metres in order to maintain full and regular power to the machines. Please also ensure that there is a minimum 32watt power outage available from your RCD situated on your Consumer Unit (fuse box). Older properties tend to be more susceptible to this being deficient. Appropriate lighting is critically required in each room and the rooms required to access the rooms that are being worked in. You should ensure that this is appropriately supplied as failure to do so may result in the work having to be cancelled and a charge up to 75% value of the total will be incurred. Heating is required in the rooms in which we are working. This is to ensure that reasonable drying times are maintained when the floors are being stained or varnished. Insufficient heating may result in a cost attached to cover the costs involved in us creating a heat supply or the additional time required to allow for the coats of lacquer to dry. Ordinarily, lacquers take between 30 minutes and 1.5 hours to dry and this time can multiply without sufficient heating and ventilation. Please ensure suitable ventilation is available.

WC facilities

WC facilities are required to be made available to our workers.

Other facilities

Water, heating and ventilation should be provided to enable an efficient working practice. Ideally, we would request that any windows that have been painted shut are released and made possible to open.

There may be a requirement for an area outside of the main property to be made available for tool/equipment storage.

Smoke alarms

In residential properties, you, our customer, is required to cover smoke alarms during the duration of the sanding process.

In commercial properties, smoke alarms should be disabled for the duration of the sanding process by you, our customer.

Access Keys and Burglar Alarm Systems

In the event that you require us to enter the property ourselves, you may be required to provide keys to access your property and any alarm codes that are needed to disable any security systems. Please note that any keys that are required to be kept overnight are kept in our safe and any burglar alarm codes are disposed of upon completion of works. PLEASE NOTE: The work we undertake requires us to maneuver large, heavy and awkward plant machinery. It also requires us to maneuver hazardous chemicals including acid catalysers. We are not insured or permitted to maneuver these items in a public environment and we do require the provision to place a vehicle within the compounds of a site in order for us to have access to the goods / materials during the course of the work. The size of the work to be completed will determine the quantity of vehicles required to do this however one vehicle is, on most occasions sufficient. On occasions where no enclosed compound facility is available for the duration of the works, then we would request that we are able to access this area for unloading and that we are given a locked 'safe room' where we are able to store the goods. In the event where there is no compound to use or that we are forced to cross the path of potential members of the public, then we must be able to position a vehicle as close to the site as possible, we must also surround the vehicle with barriers including a non public accessible 'path' down the side and back of the vehicle to maneuver the goods and for their to be a U.K. Floor Sanding supervisor or authorised personnel present to ensure that appropriate clearances are achieved when the goods are passed to the site area. We may need permission from the local council in order to do this and this may affect starting/finishing times.

Rubbish Removal

Standard rubbish removal is included in job price unless otherwise stated. Old carpet removal or other surface product is charged at £2 per square metre and carpet grippers removed at £1.50 per linear metre. Underlay is charged at £1.00 per metre for removal.
