New build mastic in Houghton, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Common call-outs are for gaps opening as the house dries out and settles and messy sealant that spoils new finishes, on plot handovers, kitchens and windows & doors.
Work in a small place like Houghton just needs the journey and access planning, and once on site, the job is the same as anywhere.
A one-year guarantee comes as standard.

Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Show homes
Bathrooms, kitchens and frames in show homes are sealed or resealed to a neat finish to a tidy standard. Tell us when the home is open so we can plan around it.

How to look after the new joints
So the new joints stay in good condition:
- Follow the cure time we give you
- Raise failed sealant with the developer while you’re covered
- Use the extractor fan every time you shower
- Photograph failed sealant before it’s redone
Don’t stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you.
Do you need new build mastic in Houghton?
Sealant is often one of the last jobs before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Most people get in touch after spotting one of these:
- Internal frame sealant that has split
- Beads laid onto grit and dust from the build
- Untidy sealant flagged on a snagging list
- Leaking shower tray seals in a new home
If you’ve bought a new home near Mottisfont & Dunbridge station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why act early in Houghton
Resealing everything on a snagging list in one visit is normally simpler than chasing joints one at a time. You get one visit and one clear quote. Around Houghton, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Why us?
- Full insurance on every job
- Quality sealants from Arbo and Everbuild
