New build mastic for homes and businesses in Findon Valley
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. If you have skirting joints opening in the first winter and internal frame sealant that has split, we can put it right, whatever the surface.
Homes around Findon Valley range from older cottages to newer houses, and their floors range just as widely, from timber that moves with the seasons to tiles laid on concrete. The sealant at skirtings and thresholds has to suit the floor it meets.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep water off fresh sealant until it has cured
- Do not wait for the house to settle if water is getting through
- Open a window or run the fan after bathing
- Resist patching a failed seal with a tube from the DIY shop
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day before water reaches them.
Early snagging is easier snagging. Small faults turn into leaks if left.
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What should I tell you?
A short description and the location. If we need more, we will ask.
How long will you be here?
It depends on the size of the job, but most jobs take a few hours in a single home. We will tell you when we quote.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Should I wait before resealing?
Any seal that is leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.

- Untidy sealant flagged on a snagging list
- Cracked sealant around new window and door frames
- Sealant applied over dusty or wet surfaces

In and around Findon Valley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
