New build mastic in Nashes Green, done properly
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Typical jobs include gaps opening as the house dries out and settles and internal frame sealant that has split, across plot handovers, kitchens and show homes.
Work in a small place like Nashes Green just needs the journey and access planning, and once on site, the job is the same as anywhere.
Big or small, you get the same 12-month guarantee.

FAQs for Nashes Green
Is Nashes Green in your area for new build mastic?
Yes. We work across London and the South East, and Nashes Green is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Can you help a landlord with a rental near Alton station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just ring 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Which products do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can new sealant go on top of the old bead?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Can you do plot mastic on a new development?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope and we’ll quote.
How long should I leave it?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours in a single home. We’ll give you a better idea when we quote.
Landlord and commercial work in Nashes Green
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
If you manage several properties in or around Nashes Green, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Don’t wait for the house to settle if water is getting through
- Keep photos and emails about snagging items
- Avoid scourers and strong chemicals on sealant
- Report sealant problems to your builder during the snagging period
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
What happens on the day
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Nashes Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- 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.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about any water getting in
- Move anything stored near the joints
- Mention any parking rules near the property

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right 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.
New homes and floors in Nashes Green
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Alton station, it’s worth checking the sealant early, while snags are still fresh.

Different surfaces, different methods
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
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.
Do you need new build mastic in Nashes Green?
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
People generally contact us when they notice one of these:
- Internal frame sealant that has split
- Sealant applied over dusty or wet surfaces
- Leaking shower tray seals in a new home
- Sealant work across a run of new homes
Around Nashes Green, as everywhere, new build mastic is only as good as the preparation behind it.
