Pine Floor Rebuilding & Insulation

Original pine boards on joists is a kind of floor that most of us consider an integral part of a building that is not removable or replaceable. Floors like that however are relatively easy to disassemble, repair, insulate and put back together. We offer complete floor insulation and rebuilding service. Any suspended floor can be insulated and rebuilt to look like a traditional pine floor with option to upgrade to different kind of wooden flooring on top.

Floor Preparation

The first step of floor rebuilding process is to lift all floorboards. Once they are up, we can assess state of supporting joists and sleeper walls. If necessary of ordered by a client, all joists can be replaced too, and sleeper walls improved or completely replaced.

It is very important that all debris is removed from subfloor. It is one of a lifetime opportunity to remove any old rubbish, dust and rubble from subfloor and we recommend having this done as all this does contribute to rot and bad smells in a house.

Floor Rebuilding Process

With an old timber structure removed and subfloor tidied up, we can proceed with floor rebuilding. Sleeper walls are being improved on or replaced completely if required. Once levelled, previously treated joist can be laid.

From the very outset we pay special attention to floor levels and existing room features. We are making sure that we maintain floor level so that new floor still plays well with existing doors and with floors in adjoining rooms as well. We also take room features into consideration. The restored floor needs to be fitted around existing fireplaces, radiators, pipes and cables.

Our team of expert fitters will make sure that the floor is replaced while still keeping everything else intact.

Insulation Method

The most efficient way of insulating a floor is by installing insulation boards in between joists. Insulation boards, also referred to as insulation foam board, loft boards, or rigid foam, are a rigid material, manufactured in sheets, to provide extra insulation within your home. Rigid board insulation is simple and easy to fit and come in a wide range of different materials, sizes and thicknesses, to ensure you can find the most suitable insulation board for your project.

We aim to apply insulation boards that are as thick as tall your joists are. This way we can make the most of your floor’s insulating potential. The insulation is held in place with wooden supports underneath. Although spaces between insulation boards and joists are very narrow, we still fill it with self expanding foam. This further improves thermal and acoustic performance of a floor and helps to hold insulation boards in place.

With subfloor prepared this way, our installers are finally ready to put the actual flooring back down. We can either put the old floor back and replace what was broken or broke during the process, or we can install a new floor. If we do down the second route, possibilities are almost endless. We can fit new boards that resemble original flooring, we can put down chipboard and install new floor on top of that, even parquet flooring.

Floor Finishing

Floor rebuilding would not be complete without applying protective sealant. Whatever is done on the flooring, it needs to be protected to last for decades to come. There are main two options when it comes to wood floor finishes and they are varnishing and oiling.

Floor varnish these days is the finish that requires the least maintenance and is the easiest to live with. It is one of these apply-and-forget finishes. Once it is down, you do not have to do anything with it. And once it wears out after years and years of usage, it needs to be sanded down back to bare wood and applied again.

Modern varnishes are very different than what most people associate with varnish. Modern products are polyurethane based (water based), they have low shine, they do not smell and they give you very natural wood colouring. Gone are the days of orange, mirror like shiny varnishes. Nobody wants that anymore and you would find that most modern floors or brand new floors you get in shops would be sealed with varnish.

The other type of finish is hard wax oil. That is a full name of a product that can be applied on wooden floors. There is a lot of misinformation out there about oil related floor finishes. Some people recommend using waxes or different kinds of oils, but these products are designed to be applied on furniture and decorative wood. Only hard wax oil is formulated to withstand foot traffic for years and it still has be to be reapplied at lease once a couple of years to prevent wear.
