How we handle floor joint sealing in Penn Street

Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check skirting joints after the heating season
- Act on grout cracks that run in a straight line
- Use furniture pads near skirting
- Ask before painting over a sealed joint
Mop with a well-wrung mop rather than flooding the floor. Keeping the edges drier helps the sealant last longer.
Small gaps are quick to seal. Ignored, they fill with dirt and open further over time.
Why it’s worth doing now in Penn Street
Water that gets past a floor joint can damage the floor beneath. Sealing them now keeps the problem at the surface. In a small place like Penn Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

New homes and floors in Penn Street
Floors around Buckinghamshire run from suspended timber in older homes to concrete in newer houses and units, and they don’t all move the same way. That is why the skirting and threshold joints need a flexible seal.
If you look after a building such as Curzon Church of England Combined School, entrance and corridor floor joints take a lot of traffic. Community buildings like Church of the Holy Trinity are part of the picture too: joints in its floors, skirtings and thresholds need resealing as they wear.

Will I be able to paint over the new joint?
For painted skirting, we use a flexible product that can be painted. Silicone won’t take paint, so we use it where the joint stays unpainted.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Do you seal warehouse floor joints?
Yes. We reseal concrete floor joints in commercial and industrial units. The product is chosen for the traffic the floor takes.
Is caulk good enough for skirting?
Only on dry joints that do not move. Caulk cracks as the floor moves. A flexible sealant is the better choice.
