How we handle new build mastic in Red Hill
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. Common call-outs are for sealant applied over dusty or wet surfaces and skirting joints opening in the first winter, across windows & doors, kitchens and plot handovers.
Older homes in small places like Red Hill often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You get a one-year guarantee, the same in Red Hill as everywhere else we work.

What we are called out for in Red Hill
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly.
The most common problems we see are:
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
In and around Red Hill, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Why act early in Red Hill
A quick bead over the top of the old sealant can look fine at first, 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. In a small place like Red Hill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours in a single home, and the area is left clean. For a village or hamlet like Red Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Mention if the joints have been sealed before
