Doing it in-house
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
About our expansion joint sealing in Westminster
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve water getting into the wall through a failed joint and chipped joint edges on forklift routes, across brickwork movement joints, precast concrete panel joints and podiums and floor movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Westminster it comes down to the same thing: the right product in a properly prepared joint.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What else we do in Westminster
Cost factors for movement joints
A fixed quote reflects the actual work. It takes account of:
- Backing rod, priming and other preparation
- The site’s rules and procedures
- Whether old sealant has to be cut out first
- Location, for remote and island sites
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.
Details that help us quote
However big the job, these details speed things up:
- Photos of the joints, close up and from further back
- The product your specification calls for
- Whether an asbestos survey exists
- Any dates the work must fit around
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email a schedule or drawings.
What happens if it’s left?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We’ll flag where edges need repair before sealing. Getting scaffold, permits or access booked in Westminster takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Why appoint us
- Matching to RAL references, product permitting

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Westminster can form part of a wider programme across Greater London.
Common questions from Westminster clients
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Will you take on work at estates like Handel Business Centre, close to Westminster?
Yes. We cover Westminster and the area around it, including industrial estates, business parks and retail parks such as Handel Business Centre. Send details of the unit and the work through our quote form for a quick quote.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
How long does movement joint sealing take?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Where floor joints take the most wear near Westminster
The 3 miles around Westminster take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Basement car parks and service yards in London tend to be in use all working day, which is why we work a few bays at a time.
In a school such as Harris Westminster Sixth Form, movement joints in brick, block and hall floors tend to be forgotten until they leak. For an estate such as Gordon Hospital, 0.5 miles south of Westminster, the joints in ramps, decks and long building elevations all need attention over time. At places like Grand Vitesse Industrial Estate (1.4 miles east of Westminster), joints are sealed a section at a time so operations carry on.
Westminster is about 1 mile south-east of City of Westminster, in Greater London. Westminster sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Our Greater London coverage takes in 764 places.

How the job changes by surface
Cladding panel joints
Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.
Brickwork and blockwork joints
Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it.
On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
- Point out any areas we must not close
- Tell us your opening times and when work is allowed
- Tell us what induction or permit system the site runs
