New build mastic for homes and businesses in Hoddesdon
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. If you have shower seals failing in the first year or two and sealant that never bonded to the surface, we can put it right.
Towns like Hoddesdon have older streets and newer estates side by side, with new homes still going up on the edge of many towns. Whether a house is brand new or a few years old, sealant and floor joints are often the first snags to show.
All our work is covered by our 12-month guarantee, wherever you are in Hertfordshire.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

When it is not the sealant
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

What we are called out for in Hoddesdon
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and the sealant may split.
Most people get in touch when they notice something like this:
- Gaps opening as the house dries out and settles
- Untidy sealant flagged on a snagging list
- Sealant work across a run of new homes
- Gaps between new skirting and floors
Around Hoddesdon, as everywhere, new build mastic is only as good as the preparation behind it.

How the job changes by surface
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
