How the job changes by surface
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We cut out the cracked bead and reseal with a flexible sealant that suits the frame.
How we handle new build mastic in Brook Green
In a new home, every joint should have a clean, even bead. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on kitchens, bathrooms & en suites and plot handovers, and common reasons people get in touch are beads laid onto grit and dust from the build and cracked sealant around new window and door frames.
Much of London’s new housing is flats in larger developments. In a new development, snags are often reported through the developer or the managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What else we do in Brook Green
Do you need new build mastic in Brook Green?
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Common reasons people contact us include:
- New-build shower sealant that has already split
- Sealant work across a run of new homes
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
If you’ve bought a new home near Kensington Olympia station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- When the joint can take water or movement
- Are they insured?
- How the surfaces are prepared before sealing
- Whether VAT is included
What affects the quote in Brook Green
For a quick quote, just ask. What matters most is:
- Which sealant suits the joint
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The size of the job
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
What to tell us for a quote
When you contact us, these details help:
- The problem you’ve noticed
- A few photos by email, if you can
- Where the job is, and your postcode
- Whether it has been sealed before
If you are in Brook Green and need new build mastic, ring 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you’ll get a clear quote before we start.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Damaged fittings that need replacing
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before you book.

Your questions about new build mastic in Brook Green
Is Brook Green in your area for new build mastic?
Yes, Brook Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Can parking be tricky for a visit in Brook Green?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, then clean and prime the joint, and a new bead applied.
Is it worth resealing while the house is still settling?
That depends on the joint. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
My new home is still under warranty. Should I contact you?
Report it to the builder first while you are covered. Once that is done, or if they won’t put it right, we can reseal it properly.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
The process
Before we leave, we go over the finished joints with you. The visit itself generally takes a few hours for most snagging lists, longer for a run of plots, depending on the size of the job. In Brook Green, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- Each joint is checked for movement before we start.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Try not to wet indoor joints just before the visit

Advice
Landlord and commercial work in Brook Green
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
New homes and floors in Brook Green
Many of London’s new homes are flats in bigger 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.
As a London address, Brook Green can be tricky for parking: let us know about parking bays, permits or a driveway.
