New build mastic in Weston, done properly
We work in new homes and on new-build sites across Weston. One shower or a whole phase of plots, the method does not change: remove, clean, prime where needed, then a neat new bead. We work on skirting & floors, kitchens and windows & doors, and the jobs we see most are sealant that never bonded to the surface and frame joints opening as the plaster dries.
For a new home in or near Weston, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
All of our work is guaranteed for twelve months.

What sealant work can’t fix
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Baths and trays that move too much for sealant to cope with
- Cracking that points to a structural problem
- Plumbing faults behind the sealant
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Weston questions
Do you cover Weston for new build mastic?
Yes, Weston is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Is Weston within the area you cover?
Yes, Weston is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Should I wait before resealing?
If the seal has failed and water is getting in, do it now. Small gaps that are just cosmetic can be resealed once movement has slowed.
Who should fix failed sealant in a new build?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do you guarantee your work?
Yes. All our work carries a 12-month guarantee.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What we do, step by step
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours in a single home. A visit to Weston is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

Joints and finishes in Weston homes
Weston is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near Sholing station, it’s worth checking the sealant early, while snags are still fresh. In and around Weston, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Weston is about 2 miles north-east of Hythe, in Southampton. Jobs in Weston get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. 40 places in Southampton are on our list, large and small.
Here we cover the SO19 and SO31 postcode area for new build mastic. Local streets include Swift Road, Scott Road and Weston Lane. We also cover Woolston (1 mile north-west), Netley (1 mile south-east), Butlocks Heath (1 mile east), Hound (2 miles south-east) and Old Netley (2 miles east).

Local landmarks in Weston
Around Weston, our work takes us to homes and buildings near Westwood Woodland Park, Woolston School and Chamberlayne College for the Arts.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not wait for the house to settle if water is getting through
- Keep pictures and emails about snagging items
- Look at the sealant regularly in the first couple of years
- Wait for the cure time before using a resealed shower
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.
Why act early in Weston
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In a smaller place like Weston, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email for an honest opinion and a quote.
