Common problems we fix in Hadleigh
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open.
If you can see any of these, it’s time to have the joints looked at:
- Shower seals failing in the first year or two
- Skirting joints opening in the first winter
- Joints pulling apart as timber shrinks
- Frame joints opening as the plaster dries
If you’ve bought a new home near Leigh-on-Sea station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we handle new build mastic in Hadleigh
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We’re often asked to deal with sealant work across a run of new homes and smeared, uneven beads picked up at snagging, on windows & doors, skirting & floors and kitchens.
In smaller places like Hadleigh, new homes tend to come as small developments or single plots. The sealant around baths, showers, frames and skirtings needs to be right from the start.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Should I try it myself first?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

How the visit works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for most snagging lists, longer for a run of plots, and we explain the cure time before we leave. For a job in Hadleigh, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- We cut out every bit of the failed or messy sealant.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Before we arrive
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

Different surfaces, different methods
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Joints and finishes in Hadleigh homes
Hadleigh is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Hadleigh, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Why act early in Hadleigh
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 Hadleigh, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Raise failed sealant with the developer while you’re covered
- Get a leaking seal dealt with right away
- Follow the cure time we give you
- Resist patching a failed seal with a tube from the DIY shop
Leave the sealant for the cure time we give you before showering or bathing. Silicone is generally left for about a day to cure enough for use.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.

How long does new build mastic take?
A typical job takes a few hours for most snagging lists, longer for a run of plots, including the preparation. Your quote will say how long we expect yours to take.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. Good preparation keeps snagging to a minimum.
Are you fully insured?
Yes, we’re fully insured for every job we do.
Will you just run a new bead over the existing one?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
When is the sealant fully cured?
That depends on the sealant used, so please follow the time we give you.
Why does sealant fail so quickly in new builds?
There are normally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
