About our new build mastic in Becontree Heath
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Typical jobs include new-build shower sealant that has already split and frame joints opening as the plaster dries, on kitchens, skirting & floors and windows & doors.
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.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

New homes and floors in Becontree Heath
Much of London’s new housing is flats in larger developments, where snags may need reporting through the developer or the managing agent. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
As a London address, Becontree Heath can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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 fails, we can still redo it.
What we are called out for in Becontree Heath
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
These are the problems we’re asked about most:
- Second-fix sealing on new plots
- Gaps behind new kitchen upstands
- Internal frame sealant that has split
- Joints pulling apart as timber shrinks
If you’ve bought a new home near Chadwell Heath station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- Which sealant they’ll use, and why
- What happens if the job turns out different
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Put sealant faults on your snagging list early
- Photograph failed sealant before it’s redone
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it as they wear the bead.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote.
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Why deal with it now?
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a flat in Becontree Heath, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Questions from Becontree Heath
I let a flat near Chadwell Heath station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Is parking an issue for new build mastic in Becontree Heath?
Parking in Becontree Heath, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
How much does new build mastic cost in Becontree Heath?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.

No. The area is protected while we work and cleaned up afterwards.
