New Build Mastic in Furneux Pelham
New-build sealant joints in Furneux Pelham need attention? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.

New build mastic in Furneux Pelham, done properly
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you’re dealing with gaps opening as the house dries out and settles and gaps behind new kitchen upstands, we can put it right.
In a village or hamlet like Furneux Pelham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
We stand behind the work with a 12-month guarantee.

What we do, step by step

Advice
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Use the extractor fan every time you shower
- Check bath and shower seals every few months as the house settles
- Photograph failed sealant before it’s redone
- Clean sealant with mild detergent, not abrasives
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you.
How the job changes by surface
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Honest limits
A few problems are outside what sealant work can do:
- Disputes or warranty claims with your builder
- Cracked trays, tiles or worktops
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
