Chieveley New Build Mastic
New-build sealant joints in Chieveley need attention? We remove the old material, prepare the joints and seal them properly, with a 12-month guarantee.

- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
New build mastic for homes and businesses in Chieveley
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have leaking shower tray seals in a new home and sealant work across a run of new homes, we can help.
Older homes in small places like Chieveley often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Why act early in Chieveley
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. A lasting seal starts with removing the old one completely. Older cottages and farmhouses around Chieveley can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

Common problems we fix in Chieveley
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Keep an eye out for any of the following:
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
- Cracks appearing as a new home settles
- Frame joints opening as the plaster dries
For new homes near Newbury Racecourse station, it’s worth checking the sealant early, while snags are still fresh.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
