Remedial sealant for homes and businesses in Temple Fortune
In Temple Fortune, as anywhere, remedial jobs tend to look alike: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We are often asked to deal with leaks that keep coming back after resealing and caulk or the wrong sealant used in a wet area, on botched or over-sealed joints, leaking tray & enclosure joints and failed movement joints.
London’s water is hard, so limescale builds up along sealant lines, in grout and on fittings. In Temple Fortune, remedial sealant is as much about a room looking cared for as about keeping water out.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Run the fan after every shower
- Always have old sealant cut out, not covered
- Report a tray that rocks or a worktop that lifts
- Don’t wait for a small gap to become a leak
Leave the new joint to cure fully before it gets wet or moves: usually around 24 hours, or as long as we advise.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.

Why act early in Temple Fortune
Adding more sealant is the usual quick fix, and it rarely works. It doesn’t grip the old layer, so the leak carries on and there’s now more to remove. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Temple Fortune, the repair is bigger than the sealant job would have been.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Why book with us
- A choice of colours where the product allows
- Homes, businesses and hotels
- Any old sealant cut out fully, not covered over
- More than 20 years in sealant work
How the job changes by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. All of it is cut out and the frame and wall cleaned.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Questions from Temple Fortune
Do you work for landlords with property near Brent Cross West station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Can parking be tricky for a visit in Temple Fortune?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
How long does remedial resealing take?
Allow a few hours, depending on how many layers have to come out. We will give you a timescale when we quote.
Can you reseal a split movement joint?
Yes. Backing sets the depth and stops the sealant sticking to the back, which lets it stretch.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you guarantee remedial jobs?
Yes, with our 12-month guarantee. Where we’ve flagged another fault, it needs fixing for the joint to last.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
