The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours for most snagging lists, longer for a run of plots. For a job in Chingford Mount, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts

How we handle new build mastic in Chingford Mount
Building dust is behind a lot of failed new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the sealant actually sticks instead of bonding to the dust. Typical jobs include second-fix sealing on new plots and gaps behind new kitchen upstands, on windows & doors, kitchens and skirting & floors.
New flats are going up across London, many of them in larger developments. Snagging there often goes through the developer or managing agent, and failed shower seals, open skirting joints and gaps at thresholds are typical.

Why it’s worth doing now in Chingford Mount
Sealant done properly at handover means fewer callbacks. Every return visit for a failed seal takes time and most come down to preparation. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Surface by surface
Windows and doors
Draughts around new frames are often a sealant gap. We look at the joints and reseal where needed.
Kitchens
As a new house dries, worktops and walls shift a little, opening gaps behind the upstand. A fresh flexible bead closes them.
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What new build mastic looks like in Chingford Mount
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. Many of London’s new homes are flats in bigger developments, where snags may need reporting through the developer or the managing agent.
As a London address, Chingford Mount can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For new homes near Highams Park station, it’s worth checking the sealant early, while snags are still fresh.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
- Wait for the cure time before using a resealed shower
- Wipe joints with warm soapy water
Do not stand on the bath edge or the lip of the tray while the sealant cures. If a bath or tray moves when you stand in it, get it looked at.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Chingford Mount: your questions answered
Do you cover Chingford Mount for new build mastic?
Yes. Our work covers London and the South East, and Chingford Mount is part of that. You can call 0345 464 0079 or email us and let us know what needs doing.
Is parking an issue for new build mastic in Chingford Mount?
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.
How do I get a quote for new build mastic in Chingford Mount?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we will talk you through it.
Do you work for letting agents?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is it normal for sealant to crack in a new home?
Lots of new homes see sealant crack early. Poor preparation at handover adds to it.
When is the best time to reseal in a new build?
Any seal that’s leaking should be redone right away. Cosmetic gaps can wait until the first year or two of movement has passed.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
