Coping and flashing joints are included where sealant is the specified fix. We work on cladding panel joints, perimeter joints where frames meet the structure and shopfront frames, and the failures we’re asked to look at most are failed seals around shopfront and entrance frames and facade joints cracked through the middle.

Questions we’re asked in Swiss Cottage
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for
Can you take on a job at a hospital such as Hospital of St John and St Elizabeth?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Is Swiss Cottage in your area?
Yes. We cover Swiss Cottage, and you can give us a call on 01277 525 020 or email a schedule or drawings to get started.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Providing access systems for the work
- Render or concrete edges that have broken away
- Water getting in through cracked render or porous masonry
Not sure which it is? You can give us a call on 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Joints and surfaces we work on
- Perimeter joints where frames meet the structure
- Cladding panel joints
- Stone and brick facade joints
- Window and door perimeters
- Shopfront frames
- Coping and flashing joints
Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Combine resealing with other works that need access
- Keep the sealant details on the building file
- Walk the elevations once or twice a year
- Insist on a full cut-out when joints are renewed
Following storms, look inside for damp or staining near frames. An early report typically means a small reseal rather than a bigger repair.
Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones.
Why deal with it now?
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 it makes sense to deal with every failing joint while access is in place.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why appoint us
- Sealing commercial buildings since 2005
- Old sealant cut out, never sealed over

Our process
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Photos, drawings or a visit tell us about the joints and the access.
- We confirm the joint type, movement and the specified product.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- The finished joints are checked with you.
What we need from you
- Flag any permit to work we will need
- Let building users know which areas are affected
- Move anything stored against the joints
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Building and refurbishing in Swiss Cottage
As part of Greater London, Swiss Cottage 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. There are plenty of hotels within about 2 miles of Swiss Cottage. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.
For a contractor at a hotel such as Marriott Hotel Regent's Park (under half a mile east of Swiss Cottage), the mastic often has to be finished before a reopening date. Units on estates such as Regis Road Business Park (to the north-east of Swiss Cottage) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. When a college such as City of Westminster College, 1.3 miles south-west of Swiss Cottage, builds or refurbishes, the mastic package typically has to fit around students and staff.
