Coombe: questions and answers
Can work at a site such as Kingston University fit around teaching?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Would you work within a site like New Victoria Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
How do I request a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Facade sealing for commercial buildings in Coombe
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on perimeter joints where frames meet the structure, window and door perimeters and shopfront frames, and what we are called in for most is weathered joints at frame-to-structure perimeters and discoloured or dirty facade joints. A specialist sealant contractor works differently from a general builder: in Coombe, that means joint design, primers and backing rod as standard.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Facades, frames and programmes in Coombe
A 2-mile radius around Coombe takes in plenty of hotels. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight. As part of Greater London, Coombe is inside the ULEZ, which applies to every van on site. Delivery slots and scarce storage shape how and when the mastic goes in.
For contractors refurbishing units at places like Shannon Commercial Centre, 1.5 miles to the south-east of Coombe, the mastic covers cladding panels, roller-door and window perimeters. Projects at colleges like Interprime College London (1.5 miles south of Coombe) tend to run to term dates, so the mastic is planned tightly.
Coombe is about 1 mile north of New Malden, in Greater London. Commercial clients in Coombe can call on us for facade joints, as part of our coverage of Greater London. Coombe is one of 764 places in Greater London on our list. Sites around London have their own page, about 9 miles away.

Signs you need facade sealing in Coombe
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.
Look out for the following:
- Gaps between rainscreen or cladding panels
- Perimeter sealant that has split or peeled away
- Draughts around frames and panels
- Previous reseals run over old sealant
New wings at hospitals like New Victoria Hospital (0.5 miles south-east of Coombe) bring long runs of window and panel joints to seal.
Questions to ask before you book
- Their public liability cover
- Will CSCS-carded applicators be on site?
- The terms of the workmanship guarantee
- Are they CHAS accredited or on Constructionline?
Why deal with it now?
Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Failed sealant in a building in Coombe can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.
Why clients in Coombe choose us
- Fully insured, including public liability cover
- Failed material removed, not covered up

When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Movement beyond what any sealant can handle
- Render or concrete edges that have broken away
- Providing access systems for the work

Diagnose, treat, sign off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- We hand over with our 12-month workmanship guarantee.
Before we start on site
- Flag any permit to work we’ll need
- Send any specification or drawings in advance
- For older buildings, check the asbestos register before work

Whether it’s one area or a whole building, these details speed things up:
- When you need the work done

- Whether an asbestos survey exists
- The product your specification calls for
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Work for main contractors and building owners
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
