New build mastic in Rivenhall End
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that’s reasonable, but a seal that’s letting water through needs doing now. If you are dealing with shower seals failing in the first year or two and internal frame sealant that has split, we can put it right, whatever the surface.
In a village or hamlet like Rivenhall End, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months, in Rivenhall End and everywhere else we cover.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Get a leaking seal dealt with straight away
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
- Avoid running a DIY bead over the old one
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
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. All the old material has to come out first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Can you do new build mastic in Rivenhall End?

Is the work guaranteed?
Yes. There’s a 12-month guarantee on every job, wherever you are.
Can you reseal over the builder’s sealant?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before we start.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it with our one-year guarantee.
Do you work through snagging lists?
Yes. Send it with pictures and we will quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Do you need new build mastic in Rivenhall End?
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
Signs it’s time to call us include:
- Sealant that never bonded to the surface
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
- Internal frame sealant that has split
Around Rivenhall End, as everywhere, new build mastic is only as good as the preparation behind it.
