New build mastic for homes and businesses in West Thorney
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on skirting & floors, bathrooms & en suites and kitchens, and the jobs we see most are new-build shower sealant that has already split and gaps between new skirting and floors.
Somewhere as small as West Thorney, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Your job is guaranteed for a year, as with all our work.

Should I go to my builder first?
Your builder, if you’re still in their snagging or warranty period. If that does not work out, we are happy to quote.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it, which can damage the surface.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and the new finishes intact.
What we do, step by step
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. In a small place like West Thorney, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children

New build mastic in West Thorney: local notes
West Thorney is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In and around West Thorney, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Southbourne station, it’s worth checking the sealant early, while snags are still fresh.

Why act early in West Thorney
The builder is generally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. In a small place like West Thorney, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
