New Build Mastic in Udimore
Our applicators work in Udimore 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.
- Untidy sealant flagged on a snagging list
- Gaps opening as the house dries out and settles
- Second-fix sealing on new plots
New build mastic in Udimore, done properly
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks rather than sitting on a layer of grit. If you have frame joints opening as the plaster dries and messy sealant that spoils new finishes, we can put it right, on skirting & floors, kitchens and plot handovers alike.
In a village or hamlet like Udimore, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Whatever the size of the job, you get the same 12-month guarantee.

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 tidy away. It generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Udimore, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Getting ready for the visit
- Tell us about any water getting in
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive

DIY sealant or a professional job?
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.
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 the job changes by surface
Plot handovers
Plot mastic is carried out to the developer’s schedule. Each joint is cleaned and primed where needed so the sealant lasts.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Ventilate bathrooms well, especially in the first year
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
- Clean sealant with mild detergent, not abrasives
Leave the sealant for the cure time we give you before showering or bathing. Silicone is usually left for about a day before water reaches them.
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.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.

What we’re called out for in Udimore
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, and the sealant sits on grit instead of the surface.
Most people get in touch when they notice something like this:
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
- Worktop and upstand sealant coming away
- Plot mastic for developers ahead of handover
For new homes near Winchelsea station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- The length of the guarantee
- Are they insured?
- When the joint can take water or movement
- How the surfaces are prepared before sealing

Should I go to my builder first?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before we start.
Why it’s worth doing now in Udimore
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it can’t bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. In a small place like Udimore, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.
