Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Floor joint sealing for homes and businesses in Fratton
Wet-area floor joints keep water out of the gap behind skirting and plinths. We seal them with a flexible, water-resistant sealant and stops dirt collecting. We are often asked to deal with cracked caulk along skirting in bathrooms and kitchens and skirting that has pulled away from the floor, on thresholds, skirting boards and wet room & bathroom floors.
In smaller places like Fratton, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
A 12-month guarantee comes as standard.

How the job changes by surface
Wet room and bathroom floors
Bathroom floors meet baths, trays, panels and skirting. They’re sealed with a flexible, anti-fungal silicone that keeps water out.
Concrete floor joints
Sawn joints in concrete floors control where it cracks. We reseal them with a floor-joint product suited to the traffic.
What we’re called out for in Fratton
Floors and walls move a little with the seasons. In winter, with the heating on, timber dries and gaps open, then close again in damper months.
The most common problems we see are:
- Open joints that fill with dirt
- Cracked grout where a tiled floor needs a movement joint
- Failed joint filler in concrete floors
- Perimeter joints in tiled floors filled with grout
Community buildings like St Mary's Church are part of the picture too: floor and skirting joints in halls and kitchens wear like any others.

Floor joint sealing around Fratton
Floors around Portsmouth run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that.
For landlords with property near Fratton station, gaps at skirtings and thresholds are worth sealing between tenancies. Managing a site like Penhale Infant School & Nursery? Then entrance and corridor floor joints take a lot of traffic.

Why it’s worth doing now in Fratton
Filling a skirting gap with caulk looks fine at first, so the gap reappears. A flexible sealant stretches instead and keeps the joint sealed. In an older home around Fratton, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
