Expansion joint sealing for commercial buildings in Brunswick Park
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. If you have leaks through car park deck joints onto the level below and expansion joints filled with dirt and stones, we can help, whatever the surface. A single leaking joint is often how a building in Brunswick Park first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around Brunswick Park, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why act early in Brunswick Park
A like-for-like reseal of a joint that keeps splitting rarely lasts. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
A quote for movement joints depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Where floor joints take the most wear near Brunswick Park
Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured. Brunswick Park has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
Schools such as St Andrew the Apostle Greek Orthodox School have movement joints in their walls and floors that are easy to overlook. For buildings at a park such as North London Business Park, less than half a mile west of Brunswick Park, brick and panel movement joints are easy to forget until one leaks.

Different surfaces, different methods

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.
Brickwork and blockwork joints
Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it.

Other services in Brunswick Park
From enquiry to sign-off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. All of Greater London is in the ULEZ, and kerbside space in Brunswick Park can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000
- Arrange parking or a loading space

Advice
Your questions answered
Can you work at a site such as North London Business Park, by Brunswick Park?
Yes, sites like North London Business Park are within our area, along with the rest of Brunswick Park. Photos and a short description are enough for a first look.
Can you take on a job at a hospital such as Priory Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Can weather delay the job?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
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.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
When to call us in Brunswick Park
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way unless width and product are reviewed.
These are often picked up first by site or facilities staff:
- Joints where the bead has lost adhesion
- Leaks through car park deck joints onto the level below
- Layers of sealant in a movement joint
- Brittle, chalky sealant on external joints
Phasing is what makes joint work possible on busy sites such as Brunswick Industrial Estate (0.5 miles south-east of Brunswick Park): one bay, aisle or car park row at a time.

Keeping the joints sound
For the best life from the joints:
- Keep racking legs and heavy point loads off floor joints
- Report split or peeling joint sealant early
- Check joints after long freezing spells
- Note which joints were done, when, and with what
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. A routine sweep is the simplest protection.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We will tell you which movement joints need doing now and which can wait.
