About our new build mastic in Quainton
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We are often asked to deal with sealant applied over dusty or wet surfaces and untidy sealant flagged on a snagging list, on show homes, kitchens and plot handovers.
Somewhere as small as Quainton, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
My new home is still under warranty. Should I contact you?
Start with the builder if you are in the snagging or warranty period. If it is not resolved, we will cut it out and reseal it.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few pictures.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
How long does new build mastic take?
Typically it takes anything from a few hours to several days, depending on the number of plots. Larger jobs naturally take longer, and we will say how long yours will take.
Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but sealant comes in other colours too. We match the colour to the finish.
New build mastic around Quainton
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Quainton, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Aylesbury Vale Parkway station, the sealant around baths, showers and frames is worth checking in the first year or two.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Ventilate bathrooms well, especially in the first year
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Record problems with dated pictures
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry and can be resealed later.
Early snagging is easier snagging. Small faults turn into leaks if left in a busy bathroom.
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. In a small place like Quainton, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk.
