New build mastic for homes and businesses in Stedham
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a failed shower or bath seal shouldn’t wait. We work on bathrooms & en suites, plot handovers and show homes, and common reasons people get in touch are gaps between new skirting and floors and frame joints opening as the plaster dries.
Older homes in small places like Stedham often have timber floors that move with the seasons, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Around Stedham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Common problems we fix in Stedham
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Look out for these signs:
- New-build shower sealant that has already split
- Gaps behind new kitchen upstands
- Sealant that never bonded to the surface
- Cracked caulk along new skirting
For jobs in and around Stedham, choosing the right material for each joint is as important as a tidy finish.

Common questions in Stedham
Do you cover smaller places like Stedham?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is new build mastic in Stedham guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or drop us an email with a short description of the job.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can landlords and businesses book you?
Yes, often. Several properties can be quoted together, and between tenancies is a good time for the work.
Are you fully insured?
Yes. Full insurance covers our work.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
- Follow the cure time we give you
Wipe the sealant with warm soapy water. Keep scourers and harsh chemicals off it as they wear the bead.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Windows and doors
A draught at a new window can be a missed or failed joint. We look at the joints and reseal where needed.
