About our new build mastic in Calcot
Some owners wait for the first year’s movement before having joints redone. For small cosmetic gaps, that is reasonable, but a seal that is letting water through needs doing now. If you have cracks appearing as a new home settles and kitchen sealant that has pulled off the wall, we can put it right, on show homes, plot handovers and skirting & floors alike.
If you’ve bought a new home in or near Calcot, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
You are covered for a year from the day we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Questions from Calcot
Is Calcot in your area for new build mastic?
Yes. Our work covers London and the South East, and Calcot is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you cover smaller places like Calcot?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope and we will quote.
Should I wait before resealing?
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.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before resealing.
Surface by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. The joint is stripped back before the new bead goes in and baths are filled before sealing.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Don’t seal over failed sealant yourself
- Report sealant problems to your builder during the snagging period
- Photograph failed sealant before it’s redone
- Watch for new gaps as the house dries out
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most snagging lists, longer for a run of plots. Parking around Calcot is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- 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.
- The finished joints are checked and the cure times given.
Preparing for the visit
- Mention any parking rules near the property
- Mention any tricky access
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.

What else we do in Calcot
Signs you need new build mastic in Calcot
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
Signs it’s time to call us include:
- Worktop and upstand sealant coming away
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
- Gaps opening as the house dries out and settles
For new homes near Theale station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
