New build mastic in Coxtie Green
Across Coxtie Green, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. We work on kitchens, windows & doors and show homes, and common reasons people get in touch are sealant applied over dusty or wet surfaces and gaps behind new kitchen upstands.
Somewhere as small as Coxtie Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Big or small, you get the same 12-month guarantee in Coxtie Green and across Essex.

Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Honest limits
We’ll always be straight with you, so here’s what sealant can’t fix:
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
- Leaking fittings rather than failed sealant

How much does new build mastic cost in Coxtie Green?
Every job is different, so each one gets its own quote. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so sealing over the top fails quickly. We cut the old bead out completely.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
How we quote for new build mastic
You will get a clear quote before we start. It takes into account:
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- Whether the work is at height
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Helping us quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- The problem you’ve noticed
- Whether it’s a home or a business
- Roughly how big the job is

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wipe joints with warm soapy water
- Keep pictures and emails about snagging items
- Look at the sealant regularly in the first couple of years
- Resist patching a failed seal with a tube from the DIY shop
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on the number of plots. Somewhere as small as Coxtie Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely, with no layer left behind.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Move anything stored near the joints
