This question asks "Do you require resin (narrow) gap filling?

This service is for the filling of gaps in between the floorboards.  If you have just a handful of radiator holes that need filling around the room, then we can sort these out for you separately and depending on the number of these, we'll do this either free of charge or by way of a nominal charge

A resin fill is what is used in the majority of cases when it comes to fillings gaps - The primary purpose of a resin fill is to aesthetically alter the look of the floor by way of installing a filler product within the gaps of the wood that, to some degree, expands and contracts with the natural and average movement of the wood.  This filler is intended for use when  a tongue and groove structure is present within the gaps of the timber floorboards. You can usually establish this by attempting to put the front end of a narrow and flat implement down the gap - if this goes through the gap, then there is no tongue & groove, if it is stopped by the tongue & groove, then there will be tongue & groove,  Be sure to check over several areas of the room as often, isolated boards have been lifted at some point (usually by plumbers or electricians) and as its usual for there to have been carpet there previously, it is somehow acceptable to them to simply 'break off' the tongue & groove whilst lifting the board.  N.B. All floorboards in a property will APPEAR to have a gap, but until a test is made, you will not be able to determine this.  IMPORTANT:  There could be either water pipes or electrical wires beneath the floor boards.  Whilst it is reasonably safe to check the gap to see if there is a tongue & groove, please note that you will be able to determinf this within a feww millememtres from the surface of the floorboard, so do not continue much past this sort of depth with any degree of force.  By law any electrical wiring should be encased in a protective wire encasement and of course your water circulates within pipework, so this gives reasonable protection against anything piercing through to the inners, however, if you use soemthing like a blunt knife to check the gap/tongue and groove, be very careful and aware of the possible hazardous repurcussions.

The correct purpose of the resin filler is to sit on top of the 'tongue' situated within the gap.  IMPORTANT NOTICE:  Neither the manufacturers nor ourselves, can guarantee the filling if either, there isnt a 'tounge & groove' structure to your boards or if the sub-structure or wod floor timber itself is so unstable, that it is caused to moved exessively when it is walked upon or when any form of weight is applied to it.  We have on numerous occasions, resin filled boards where a tongue & groove has NOT been present and whilst it is rare, we have, on occasion, had people later mention that the filler had fallen through or come out.  This is not a failing on part of the filler nor of the way in has been filled because it is not meant for this purpose, but there is a reasonable 'chance' that this will satisfy most needs.  The filler is lacquered over, post filling and it is thought that when doing this, the laquer is absorbed by the filler, thus creating some degree of additional stability for the filler.  This is only an assupmtion, because so many instances come about where the filler seems to'hold up' even without a base to sit on. However this should not be relied upon or expected to happen and is not guaranteed.

The process of filling the gaps is done firstly by mixing the resin with the fine dust brought about by the sanding of your boards.  The colour similarity is not guranteed as each piece of timber varies in colour, but it results in something that is usually reasonably similar to the colour of the boards - be aware that the colour can vary agin if a heavier mix has to be made, thus making the colour darker but the sanding operatives will only do this when they feel it is required.  If we are holding stock of the same type of timber dust to that of your floor, then we may choose at our discretion to use this dust prior to the sanding process. The reason for this is that the filling process is a lot smoother as we dont have the same level of friction between the filler and wood and you effectively get a heavier 'fill' thus providing a better chance of having an even finish.  In addition, the varnishing of the filler can make the filling product look darker. Again, the colour is acceptable by the vast majority, but be mindful that in the unlikely event that this becomes a possible issue, that we are not repsonsible for the evential colour and/or any removal or re-instatement of the filler will be charged for, as an additional cost to the job.  To date, very rarely has this been necessary.  The filler may be aopplied on 2 or 3 occasions if we encounter 'sinkage' thereafter, we consider the gap has had enough product to fill a 'normal expected' gap and any further sinkage or dip or 'drop' has to be considered as an imperfection of your exisiting floor and, short of replacing the board (which would attract a cost) nothing more can be offered so far as resin fill and may need to be treated as an allowable compromise.

Whilst we may have highlighted the pitfalls and possibilities of the filling, on the whole, most result in a totally satisfactory finish.
