New build mastic in Brent Park: local notes
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Stonebridge Park station, it’s worth checking the sealant early, while snags are still fresh. As a London address, Brent Park can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

New build mastic in Brent Park, 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 instead of bonding to the dust. We work on show homes, windows & doors and bathrooms & en suites, and common reasons people get in touch are skirting joints opening in the first winter and gaps behind new kitchen upstands.
London homes range from new-build flats to period conversions with new floors laid over old boards. Every joint between floor, skirting and threshold has to cope with some movement.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What else we do in Brent Park
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Watch for new gaps as the house dries out
- Avoid scourers and strong chemicals on sealant
- Get a leaking seal dealt with right away
- Ventilate bathrooms well, especially in the first year
Keep photos of the joints and any snagging correspondence with your builder. 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.
What we do, step by step
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, and the area is left clean. In Brent Park, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
Ask for a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.

What the job involves on each surface
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. A proper reseal keeps water in the tray.
What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
- Movement caused by a poorly fitted tray or bath
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Do you work for landlords with property near Stonebridge Park station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.

How long does the job take?

Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Why act early in Brent Park
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email and we’ll talk you through it.
Why book with us
- Full insurance on every job
- One-year guarantee on every job
- Arbo and Everbuild products

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
