How we handle new build mastic in Bucknell
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. If you are dealing with frame joints opening as the plaster dries and gaps behind new kitchen upstands, we can put it right, whatever the surface.
Work in a small place like Bucknell just needs the journey and access planning, and the work itself is the same as on any site.

Quotes for new build mastic in Bucknell

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around Bucknell can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Advice
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Ventilate bathrooms well, especially in the first year
- Don’t wait for the house to settle if water is getting through
- Do not seal over failed sealant yourself
- Wait for the cure time before using a resealed shower
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements.
Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.
