Uxbridge New Build Mastic
Our applicators work in Uxbridge on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Frame joints opening as the plaster dries
- Leaking shower tray seals in a new home
- Beads laid onto grit and dust from the build
Looking after it afterwards
To keep the joints looking good and working properly:
- Look at the sealant regularly in the first couple of years
- Do not seal over failed sealant yourself
- Wipe joints with warm soapy water
- Record problems with dated photos
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
New build mastic in Uxbridge, done properly
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a seal that’s letting water through needs doing now. Typical jobs include internal frame sealant that has split and shower seals failing in the first year or two, on kitchens, bathrooms & en suites and show homes.
Where new homes go up in smaller places like Uxbridge, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
Every job is covered by a one-year guarantee, wherever you are in Buckinghamshire.

Why deal with it now?
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 an older home around Uxbridge, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
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.
Why us?
- Every job guaranteed for a year
- Anti-fungal silicone where joints get wet
- White, clear, grey or another colour, product permitting
- Arbo and Everbuild products

How the job changes by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We cut out the cracked bead and reseal with a flexible sealant in a matching colour.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Uxbridge: your questions answered
I let a flat near West Drayton station. Can you help?

When is the sealant fully cured?
It depends on the product. Before we leave, we’ll tell you the cure time.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, large or small.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Should I wait before resealing?
Where water is getting through, don’t wait. Hairline cosmetic gaps can wait until the house has settled.

Should I try it myself first?

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What sealant work cannot fix
We will always be straight with you, so here’s what sealant can’t fix:
- Cracked trays, tiles or worktops
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think.

How it works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots and we leave things clean and tidy. For a job in Uxbridge, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We check every joint and leave you with the cure times.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
