New build mastic in Crabtree
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 kitchens, plot handovers and bathrooms & en suites, and the jobs we see most are messy sealant that spoils new finishes and cracked sealant around new window and door frames.
For a small place like Crabtree, the journey and access are planned in advance, and the work itself is the same as on any site.
Each job carries a 12-month guarantee.

Looking after it afterwards
After the cure time, these simple habits help:
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with straight away
- Avoid scourers and strong chemicals on sealant
- Look at the sealant regularly in the first couple of years
Keep photos of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.

What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Around Crabtree, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What you get with us
- Over 20 years’ experience
- Neat joints and a tidy finish

Different surfaces, different methods
Windows and doors

Skirting and floors
Floors and skirting move as the house dries and the heating runs. We use a flexible product rather than caulk in a colour to suit.
