Expansion joint sealing for commercial buildings in West Hampstead
We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we will confirm the choice in the quote. If you have damp inside where a wall movement joint has failed and weathered movement joint sealant that no longer flexes, we can put it right, whatever the surface. One point of contact handles commercial sealant work in West Hampstead from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Around West Hampstead, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
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.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. Planning a London job such as one in West Hampstead starts with access: 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.
- 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.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Flag any permit to work we’ll need
- For older buildings, check the asbestos register before work
- Move anything stored against the joints

Why act early in West Hampstead
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. Getting scaffold, permits or access booked in West Hampstead takes effort, so it makes sense to deal with every failing joint while access is in place.
Pricing movement joints depends on how many there are, their condition and the access. Call for a quote.

How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- How accessible the joints are
- The product specified
- Working within restricted access windows
- Removal of failed or old sealant
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What to include in your enquiry
Diagnosis starts before we arrive. Tell us:
- Where the site is, with the postcode
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
- Any specification or named product
Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, ring 01277 525 020 or email us.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Put movement joints on the planned maintenance inspection round
- Check joints after long freezing spells
- Brief car park operatives to protect joint lines during winter clearance
- Record the sealant used and the date in the O&M file
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.
Surface by surface
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.
Cladding panel joints
We confirm what access is in place before pricing. Close-up photos help us judge the joints or a site visit fills the gaps.
FAQs: West Hampstead
Do you take on jobs in West Hampstead where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Do you take on work at healthcare sites like Royal Free Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Does the weather affect joint sealing?
Sealing onto a damp surface leads to adhesion failure so we’d rather rearrange than seal in the rain. We agree a revised date with you.
Are expansion joints and movement joints the same thing?
Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Can the building stay open while you work?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.

When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Crumbling edges that would give a new bead nothing sound to grip
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
If you are not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.
