Our process
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. In West Hampstead, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Send any specification or drawings in advance
- Warn occupants and staff about the work

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Advice
Facade sealing for commercial buildings in West Hampstead
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on shopfront frames, cladding panel joints and stone and brick facade joints, and the usual reasons a site gets in touch are staining on stone next to old sealant and damp patches beside frames after rain.

Facade sealing around West Hampstead: points for this area
The area within 2 miles of West Hampstead holds plenty of hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. As part of Greater London, West Hampstead is inside the ULEZ, which applies to every van on site. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Units on estates such as The Quadrant Business Centre (to the south-west of West Hampstead) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. On a healthcare site such as Royal Free Hospital, 1 mile to the east of West Hampstead, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For a contractor at a hotel such as Quality Hotel Hampstead, 0.5 miles to the south-east of West Hampstead, the mastic often has to be finished before a reopening date.
West Hampstead is about 3 miles north-west of City of Westminster, in Greater London. Anywhere in NW3, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

- Site requirements such as inductions and permits
- Distance, for remote addresses
- Quantities, in metres or numbers
- Specialist products, such as fire-rated or hygienic sealants
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
Details that help us quote
The more we know, the firmer the quote. When you get in touch, include:
- Approximate linear metres or a joint schedule

- The site address and postcode
- What the building is and how it’s used

What else we do in West Hampstead
After the work
Once the work is signed off, a little attention goes a long way:
- Ask about asbestos in pre-2000 mastic
- Insist on a full cut-out when joints are renewed
- Don’t wait for a second leak before calling
- Keep pressure washers away from fresh sealant
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.
Surface by surface
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.
Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
FAQs: West Hampstead
Can you work at a site such as The Quadrant Business Centre, by West Hampstead?
Yes. Estates, retail parks and business parks around West Hampstead, The Quadrant Business Centre among them, are all within reach. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Can you take on a job at a hospital such as Royal Free Hospital?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Can you find out why a window is leaking?
Yes. We check the sealant joints and report what we find before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
Is West Hampstead in your area?
Yes. West Hampstead is in our area. For a quote, phone 01277 525 020 or email the details over.
How long does a job like this take?
That varies with the scale of the job, though a typical visit normally takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
