Mastic sealing in Ham
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. Most enquiries involve the same joint failures repeated across a portfolio and damaged joints in communal entrances and corridors, on external wall and movement joints, communal kitchens and washrooms and shopfronts below residential blocks. Facilities teams, main contractors and managing agents in Ham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
London’s ULEZ covers every borough, and parking and loading rules vary street by street. For block-wide work, a place to park and store materials saves time on every visit.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

FAQs: Ham
Do you take on jobs in Ham where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Will you take on a block within reach of Teddington station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Can you plan resealing across several buildings?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Quoting for work in Ham
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Working within restricted access windows
- How much existing material needs removing
- The product specified
- Distance, for remote addresses
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- The site address and postcode
- How the joints are reached, and at what height
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email us with what you know.
Owners, agents and contractors
Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Planned mastic for Ham portfolios
In London, mastic work on a block goes through the managing agent or landlord, with notice to residents. We fit the programme to your notice periods.
Schools and community buildings such as Meadlands Primary School need frame and external mastic kept sound like any building. Property owners at sites such as St. George's Industrial Estate, 0.5 miles south-east of Ham, can have mastic renewed between lettings.
Ham is about 1 mile south-east of Twickenham, in Greater London. Looking for mastic sealing in Ham? We can help, as we do across Greater London. Across Greater London, 764 places are covered, including Ham. Sites around London have their own page, about 10 miles away.

Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a job in Ham, access comes first. Send the building rules and access times with your enquiry.

Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Tidy, sound joints keep them looking cared for.
Estate-wide resealing programmes
Using the same products throughout keeps the estate consistent.
When to call us in Ham
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.
Common reasons buildings call us in:
- Draughts at frames across a block
- A mix of products and colours from past repairs
- Brittle perimeter mastic across a building
- Movement joints with sealant missing
Blocks of flats and mixed-use buildings often cluster around stations such as Teddington station (to the south-west of Ham) and their window and balcony mastic tends to age at the same rate across a building.
Questions to ask before you book
- Proof of insurance
- How joint depth will be controlled
- Whether their applicators hold CSCS cards
- Which product they’ll use, and why it suits the joint
