Sub-floor preparation

What we do

Sub-floor preparation

Almost every flooring failure we get called out to look at is a sub-floor failure wearing a flooring costume. LVT showing every screw head. A floating laminate that flexes and splits at the joints over a dip. Solid oak that cupped because nobody took a moisture reading off a slab that was still green. The floor gets blamed; the preparation was the problem.

So we treat it as its own stage with its own line on the quote. That means a moisture test on any concrete or screed before anything else is decided, a flatness check across the room rather than a glance, and then whatever the reading and the survey call for — latex smoothing compound to take out undulation, a ply overlay where boards are uneven or springy, a liquid or membrane damp-proof course where moisture is present, and screws into any board that moves.

We also do this as a standalone job. If you have a fitter lined up, or you are laying the floor yourself and want the base right first, we will prepare the sub-floor and hand it over flat, dry and documented. That is a legitimate way to buy it and we are happy to work that way.

Best for: New builds with green screed, period properties with uneven boards, and any LVT or wide-plank installation.
