New build mastic in Leyton Grange
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on plot handovers, kitchens and skirting & floors, and people most often call us about worktop and upstand sealant coming away and cracks appearing as a new home settles.
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.
Each job carries a 12-month guarantee.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Put sealant faults on your snagging list early
- Resist patching a failed seal with a tube from the DIY shop
- Wait for the cure time before using a resealed shower
- Open a window or run the fan after bathing
Wipe the sealant with warm soapy water. Avoid abrasive pads and strong solvents, which can damage the surface.
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.

Leyton Grange questions
Can parking be tricky for a visit in Leyton Grange?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
Is Leyton Grange in your area for new build mastic?
Yes. Our work covers London and the South East, and Leyton Grange is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do.

Are you insured?

What new build mastic looks like in Leyton Grange
Many of London’s new homes are flats in bigger 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Leyton Grange is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

How it works
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. 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 go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Surfaces are cleaned of building dust and primed where needed.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Mention any tricky access
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints

It’s worth asking for a quote if you see:
- Smeared, uneven beads picked up at snagging
- Cracked caulk along new skirting
- Gaps behind new kitchen upstands
- Plot mastic for developers ahead of handover

- Whether the sealant suits the joint
- How much experience the applicator has
- Whether you can choose the colour
Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. We seal them with a sealant suited to wet areas.
