Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- On pre-2000 buildings, share the asbestos information before work starts
- Add sealant to the planned maintenance inspection list
- Report cracked or peeling sealant early
- Ask fit-out and M&E contractors to report any sealant they disturb
Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. If that happens, ring 01277 525 020 or email us and we will price putting it right.
Once sealant fails in a movement joint, grit and debris get in. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.
Commercial sealant contractors for commercial buildings in Swiss Cottage
Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Swiss Cottage, give us a call on 01277 525 020 or email drawings and photos with the site addresses. We work on window and door perimeters, external facade joints and washrooms and tea points, and the usual reasons a site gets in touch are smeared sealant across finishes from a rushed job and frame mastic that has hardened and come away from the wall. Whether you call it commercial sealant work, mastic application or joint sealing, in Swiss Cottage it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
If you look after more than one building near Swiss Cottage, the work can be planned as one programme, so standards and paperwork match across every site.
In London, most commercial sealant work happens in buildings that stay open: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Quoting for work in Swiss Cottage
To price the job, we consider:
- Any access equipment needed
- Travel to remote or island sites
- Backing rod, priming and other preparation
- Working within restricted access windows
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
Sending details for a quote
To price the job accurately, we need a clear picture of the site. Send us:
- The site address and postcode
- Approximate linear metres or a joint schedule
- Whether the building will be occupied during the work
- The asbestos register, for older buildings
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.
What we are called out for in Swiss Cottage
A split down the middle of the bead tells a different story. Normally the movement was too much for the sealant chosen. The same product in the same joint tends to fail the same way, so width, depth and product are checked before we quote.
Clients usually get in touch after noticing something like this:
- Untidy joints in a reception, shop floor or lobby
- Movement joints packed with grit and debris
- Shrunken sealant along kitchen worktops and splashbacks
- Sanitary sealant that has gone black and patchy
In hotels such as Marriott Hotel Regent's Park, under half a mile to the east of Swiss Cottage, refurbishments normally mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

General trades versus a 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.
Common questions from Swiss Cottage clients
Must a hotel around Swiss Cottage close while you work?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.
Do you cover Swiss Cottage?
Yes. We cover Swiss Cottage and the rest of Greater London. For a quote, call the office on 01277 525 020 or email a schedule or drawings.
Are your applicators CSCS-carded?
Yes. If you need card details for site access, tell us and we will confirm them with the quote.
Do you take on multi-site sealant work?
Yes, across South East England, Greater London and all of Scotland. Each site gets the same process and a single contact.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a few hours to several days on most single sites, depending on joint lengths and access. For a job in Swiss Cottage, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- We start with the evidence: photos, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
What we need from you
- Send any specification or drawings in advance
- Tell us which areas need to stay in use
- Warn occupants and staff about the work

Surface by surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in.
Facade and cladding joints
Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.
