Expansion joint sealing for businesses in Swiss Cottage
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Look over external and deck joints after a hard winter
- Reopen bays and walkways only after the stated cure time
- Clear dirt from joint lines during routine cleaning
- Note which joints were done, when, and with what
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.
About our expansion joint sealing in Swiss Cottage
Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied. The enquiries we see most involve joints packed with grit and debris and sealant pulling off the joint face, across precast concrete panel joints, brickwork movement joints and podiums and floor movement joints. A specialist sealant contractor works differently from a general builder: in Swiss Cottage, that means joint design, primers and backing rod as standard.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Swiss Cottage means thinking about access, loading times and the ULEZ as well as the joints.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Slabs, ramps and loading bays in Swiss Cottage
The 3 miles around Swiss Cottage take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager.
A healthcare site such as Hospital of St John and St Elizabeth, 0.6 miles to the south of Swiss Cottage, depends on car parks, ramps and service yards whose joints take traffic all day. Parks like Regis Road Business Park, 1.4 miles to the north-east of Swiss Cottage, combine paved areas, car parks and building elevations, each with joints that move. For a centre such as O2 Centre, which lies north-west of Swiss Cottage, the service yard and car park joints usually need attention first.
Swiss Cottage is about 1 mile south of Hampstead, in Greater London. Anywhere in NW3, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 764 places in Greater London, from busy centres to rural villages.

FAQs: Swiss Cottage
Do you cover business parks and estates near Swiss Cottage, such as Regis Road Business Park?
Yes. We cover Swiss Cottage and the area around it, including industrial estates, business parks and retail parks such as Regis Road Business Park. Photos and a short description are enough for a first look.
Do you take on work at healthcare sites like Hospital of St John and St Elizabeth?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Do the joint edges need to be sound before sealing?
Sound edges are essential. If they’re damaged, we will say so before any sealing so you’re not paying for a bead that won’t hold.
What timescale should we allow for resealing expansion joints?
Expect a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, with phasing where areas must stay open. Cure time before reopening is confirmed on the day.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Owners, agents and contractors
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

What else we do in Swiss Cottage
Cost factors for movement joints
A fixed quote reflects the actual work. It takes account of:
- How much existing material needs removing
- Backing rod, priming and other preparation
- How accessible the joints are
- Induction, permit and paperwork requirements
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
We can often quote from photographs and a few details. Please tell us:
- Rough lengths or quantities, or drawings if you have them
- Whether the building will be occupied during the work
- Whether an asbestos survey exists
- Where the site is, with the postcode
For a fixed quote, call the office on 01277 525 020 or email us, telling us the site location and the nature of the job. Our quote form is another easy route.
Different surfaces, different methods
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.
Why act early in Swiss Cottage
Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex, so it fails quickly. We cut out the old seal and prepare the faces every time. In a London building, a failed joint rarely affects only one party: 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, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In Swiss Cottage, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Tell staff and tenants when we will be in
- Share your working hours and any access restrictions
- Share the asbestos register for older buildings
