New build mastic in Wimbledon Chase
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on show homes, kitchens and plot handovers, and common reasons people get in touch are smeared, uneven beads picked up at snagging and gaps between new skirting and floors.
Across London, commercial floors have movement joints that break down under heavy foot traffic, while new homes need a neat, sound finish around frames, baths and kitchens before handover, in Wimbledon Chase and beyond.
Whatever the size of the job, it’s backed by our one-year guarantee in Wimbledon Chase and across Greater London.

When to call us in Wimbledon Chase
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
These are the problems we’re asked about most:
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
- Cracks appearing as a new home settles
- Untidy sealant flagged on a snagging list
If you’ve bought a new home near Wimbledon Chase station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How the joint is cleaned and prepared
- Which colour the sealant will be
- Whether the sealant suits the joint
- How long to leave it before use
The process
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes a few hours for most snagging lists, longer for a run of plots. In Wimbledon Chase, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- 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.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

Advice
Wimbledon Chase: your questions answered
Is parking an issue for new build mastic in Wimbledon Chase?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
I let a flat near Wimbledon Chase station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can call 0345 464 0079 or email us with the details for a clear quote.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, the joint cleaned and primed where needed, before resealing.
Can you work from my snagging list?
Yes. Send it with photos and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.

When something else is needed
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly before you book.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Raise failed sealant with the developer while you’re covered
- Avoid running a DIY bead over the old one
- Follow the cure time we give you
- Photograph failed sealant before it’s redone
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
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.
Quotes for new build mastic in Wimbledon Chase
Call for a quick quote. The main things that affect it are:
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- The number and length of the joints
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- If someone has resealed it before
- Whether it’s a home or a business
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or send us an email.
Why it’s worth doing now in Wimbledon Chase
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or is not dealt with, we can reseal it properly. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Wimbledon Chase, the repair is bigger than a sealant job.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
Why us?
- A sealant colour to suit the surroundings
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows
- Every job guaranteed for a year

New build mastic in Wimbledon Chase: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
