Why act early in North Sheen
Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Pricing facade joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Facade sealing in North Sheen
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. If you are dealing with leaks at window and door perimeters and patch repairs that keep failing, we can put it right. Whoever orders the work in North Sheen, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around North Sheen, as across London, much of the work is refurbishing existing buildings as well as building new ones. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
A 12-month guarantee applies to all our work in Greater London. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Building owners, agents and FMs in North Sheen
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around North Sheen. One quote can cover more than one site, so there’s one set of paperwork to deal with.
How the job changes by surface
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus neutral-cure product, chosen for the frame and wall, goes in, tooled to shed water.
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. 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.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- Failed beads are removed in full and the joint faces cleaned.
- Primer goes on where the product data asks for it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
Before we start on site
- Share your working hours and any access restrictions
- Flag any permit to work we will need
- Clear stock, furniture or equipment away from the joints

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Keep sills, gutters and drainage paths clear
- Ask about asbestos in pre-2000 mastic
- Plan facade sealing alongside redecoration
- Walk the elevations once or twice a year
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant, so brief your window cleaners.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and work stops until it’s tested if it’s suspected.
Your questions answered
Will you take on work at estates like Kew Retail Park, close to North Sheen?
Yes. Estates, retail parks and business parks around North Sheen, Kew Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Will you plan work around the academic year at somewhere like Richmond American University London?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you look at water coming in around a frame?
Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Do you run new sealant over the existing bead?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Do you replace windows or glass?
No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.
Which sealant do you use on facades?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.
