About our construction mastic in Chadwell Heath
A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility. Site teams most often ask us about external joints sealed in damp or cold conditions that are now failing and internal caulk splitting as the building dries out, on brick and block movement joints, window and door perimeters and floor and skirting junctions. Most enquiries from Chadwell Heath start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Every London site, Chadwell Heath included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites usually need booked deliveries and a plan for where materials go.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits
Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:
- Damage to finishes by other trades after we have sealed
- Faulty frames rather than failed sealant
- Oversized gaps that need packing or adjustment by others
If you are not sure, just give us a call on 01277 525 020 or email drawings and photos and we will give you a straight answer.

Different surfaces, different methods
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. The design and sign-off of fire stopping sit with the designer, principal designer or fire engineer; we work to the specification and the manufacturer’s installation guidance.
Snagging before handover
The last pass before handover is where mastic snags are cleared. We can work through the snag list area by area and damaged joints are redone rather than patched.
Chadwell Heath: questions and answers
Do you take on jobs in Chadwell Heath where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Do you take on work at healthcare sites like Goodmayes Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Chadwell Heath in your area?
Yes. Chadwell Heath is in our area. To discuss a job, call 01277 525 020 or email us.
Do you take on mastic snagging only?
Yes. Snag-only work is something we take on, cutting out damaged or poor joints and resealing them.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Commercial clients in Chadwell Heath
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Chadwell Heath can sit alongside others in a wider programme across Greater London.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- Drawings, specification and programme come to us.
- We take off quantities and return a fixed quote.

Related advice
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Common problems we fix in Chadwell Heath
Wide, tapered or inconsistent gaps around frames are a common problem. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
These are often picked up first by site or facilities staff:
- Different trades sealing to different standards
- Frame gaps too wide for sealant alone
- Internal caulk splitting as the building dries out
- Window and door perimeters that won’t pass inspection
Projects at colleges like New City College (to the west of Chadwell Heath) tend to run to term dates, so the mastic is planned tightly.
