New build mastic in Coggins Mill, done properly
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on windows & doors, show homes and skirting & floors, and people most often call us about second-fix sealing on new plots and worktop and upstand sealant coming away.
Around Coggins Mill, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Each job carries a 12-month guarantee, large or small.

What we’re called out for in Coggins Mill
Sealant applied onto damp surfaces doesn’t bond well. On a busy site, joints are not always given time to dry.
Signs it’s time to call us include:
- Kitchen sealant that has pulled off the wall
- Cracks appearing as a new home settles
- Cracked sealant around new window and door frames
- Plot mastic for developers ahead of handover
Around Coggins Mill, as everywhere, new build mastic is only as good as the preparation behind it.

Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job, large or small.
How much does new build mastic cost in Coggins Mill?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
How the job changes by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Advice
Why it’s worth doing now in Coggins Mill
A quick bead over the top of the old sealant can look fine at first, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. In a small place like Coggins Mill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
