How we handle new build mastic in Green Park
For builders and developers, we work through plots to the schedule you give us. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover with a sealant suited to each area. Common call-outs are for smeared, uneven beads picked up at snagging and sealant that never bonded to the surface, on bathrooms & en suites, skirting & floors and plot handovers.
Around Green Park, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What we are called out for in Green Park
Not every new-build joint gets the right sealant: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Look out for any of the following:
- Plot mastic for developers ahead of handover
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
- Gaps behind new kitchen upstands
Around Green Park, as everywhere, new build mastic is only as good as the preparation behind it.

When it isn’t the sealant
New sealant can’t fix everything, and we will tell you before we start. Sealant won’t put right:
- Leaks from pipes, valves or wastes, which need a plumber
- Deciding who is responsible under a builder’s warranty
- Baths and trays that move too much for sealant to cope with
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before you book.

DIY sealant or a professional job?
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.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why act early in Green Park
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. In a small place like Green Park, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
