New build mastic in Upper Brailes, done properly
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on windows & doors, bathrooms & en suites and skirting & floors, and the jobs we see most are second-fix sealing on new plots and gaps between new skirting and floors.
Around Upper Brailes, 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.
All of our work is guaranteed for twelve months, in Upper Brailes and everywhere else we cover.

Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and prime where the product needs it.
Show homes
We seal show-home bathrooms, kitchens and frames. We’ll plan around viewing times.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Put sealant faults on your snagging list early
- Use the extractor fan every time you shower
- Avoid running a DIY bead over the old one
- Clean sealant with mild detergent, not abrasives
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
- Structural cracks in walls or ceilings
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

Why act early in Upper Brailes
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Upper Brailes can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Common problems we fix in Upper Brailes
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Any of these means the joints need attention:
- Sealant that never bonded to the surface
- Cracked caulk along new skirting
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
For jobs in and around Upper Brailes, choosing the right material for each joint is as important as a tidy finish.
