About our new build mastic in Leytonstone
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. We’re often asked to deal with leaking shower tray seals in a new home and cracks appearing as a new home settles, on kitchens, windows & doors and plot handovers.
Shops, offices and commercial units across London have hard-wearing floors with movement joints that need resealing as they wear, and new homes need their plot mastic finished properly before handover, in Leytonstone and beyond.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Plumbing faults behind the sealant
- Disputes or warranty claims with your builder
- Baths and trays that move too much for sealant to cope with
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.
Surfaces we seal
- Bathrooms & en suites
- Plot handovers
- Kitchens

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours in a single home, depending on how much there is to do. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Tell us if parking is tricky

Related advice
Do you need new build mastic in Leytonstone?
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
Look out for any of the following:
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
- New-build shower sealant that has already split
- Internal frame sealant that has split
As a London address, Leytonstone can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Leytonstone: your questions answered
Can you help a landlord with a rental near Leytonstone High Road 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 will give you a fixed price before work begins.
Is Leytonstone in your area for new build mastic?

Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Can I send you my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. Items that need a plumber, tiler or the builder are flagged.
Should I wait before resealing?
Any seal that’s leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
How long will you be here?
A typical job takes anything from a few hours to several days, depending on the number of plots. We will confirm how long when we quote.

Joints and finishes in Leytonstone homes
Much of London’s new housing is flats in larger developments, where snagging may go through the developer or managing agent. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

DIY versus a professional finish

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
