Expansion joint sealing for commercial buildings in Summerstown
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. Most enquiries involve arrises breaking up along floor joints and torn sealant in brick or block movement joints, on brickwork movement joints, cladding panel joints and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Summerstown, 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. In Summerstown, as everywhere in London, access, loading and the ULEZ all come into the plan.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

What happens if it’s left?
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. 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.
Pricing movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

When to call us in Summerstown
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.
Things that usually lead to an enquiry:
- Leaks through car park deck joints onto the level below
- Water getting into the wall through a failed joint
- Joints where the bead has lost adhesion
- Torn sealant in brick or block movement joints
Parks like Garratt Business Park, less than half a mile to the south-west of Summerstown, combine paved areas, car parks and building elevations, each with joints that move.
Questions to ask before you book
- Their plan for phasing and protecting the area
- What site paperwork they can supply
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How the joint faces will be prepared and primed
Floors, slabs and movement joints in Summerstown
London car parks, loading bays and podium decks often can’t close for long, so joints are sealed in sections with each area handed back once cured. At least three named trading, business or retail sites lie within about 3 miles of Summerstown. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
University campuses such as Kingston University Roehampton Vale Campus (to the west of Summerstown) have car parks, paved walkways and building elevations with movement joints. A healthcare site such as Springfield University Hospital (to the east of Summerstown) depends on car parks, ramps and service yards whose joints take traffic all day.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Cracking or settlement that calls for an engineer’s assessment
If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer.
What we seal
- Cladding panel joints
- Blockwork control joints
- Brickwork movement joints
- Podiums and floor movement joints
- Precast concrete panel joints
- Car park decks and ramps
Keeping the joints sound
Cleaning and maintenance staff play a part too. Share these points with them:
- Raise snow-clearing blades over deck joints where possible
- Inspect movement joints alongside other routine building checks
- Look over external and deck joints after a hard winter
- Keep stones and debris out of open joint lines
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. A routine sweep is the simplest protection.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a job in Summerstown, access comes first: 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.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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
- Send asbestos survey details if the building is pre-2000
- Let building users know which areas are affected
- Tell us which areas need to stay in use
