New build mastic for homes and businesses in Leagreen
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. We’re often asked to deal with second-fix sealing on new plots and frame joints opening as the plaster dries, on bathrooms & en suites, kitchens and skirting & floors.
Work in a small place like Leagreen just needs the journey and access planning, and once on site, the job is the same as anywhere.
All our work is covered by our one-year guarantee.

New homes and floors in Leagreen
Leagreen is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For new homes near New Milton station, it’s worth checking the sealant early, while snags are still fresh.

What happens if it’s left?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Where a wall is exposed, as many are in small places like Leagreen, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

What the job involves on each surface
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. Resealing properly keeps water where it belongs.
Show homes
Show homes need sealant that looks right from day one. We lay neat, even beads in colours to suit the finishes.
When something else is needed
To be straight with you, there are a few things sealant won’t fix:
- Broken tiles or a split tray
- Disputes or warranty claims with your builder
- Settlement cracks that need a surveyor
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before you book.
Surfaces we seal

Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or email us with a short description of the job.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How it works
We bring everything the job needs with us, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Leagreen, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Advice
Signs you need new build mastic in Leagreen
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.
Signs it’s time to call us include:
- Joints pulling apart as timber shrinks
- Beads laid onto grit and dust from the build
- Sealant work across a run of new homes
- Smeared, uneven beads picked up at snagging
In and around Leagreen, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
