Advice
New build mastic in Brock Hill, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on show homes, windows & doors and skirting & floors, and people most often call us about plot mastic for developers ahead of handover and shower seals failing in the first year or two.
Work in a small place like Brock Hill just needs the journey and access planning, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What happens if it’s left?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times for the lot. Around Brock Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Do you need new build mastic in Brock Hill?
The first winter with the heating on dries a new home quickly. Gaps open along skirting, frames and worktops.
Look out for these signs:
- Gaps between new skirting and floors

For new homes near Wickford station, it’s worth checking the sealant early, while snags are still fresh.

Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.

Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.

How long does the job take?
