Honest limits
Our job is the joint, not everything around it. On its own, sealant can’t deal with:
- Damaged metal nosings or cover plates over a joint
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Joints too narrow for the movement, which need redesigning by the engineer

Expansion joint sealing in West Green
A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on podiums and floor movement joints, brickwork movement joints and car park decks and ramps, and the usual reasons a site gets in touch are rain penetration at brick or block movement joints and previous reseals laid over old sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in West Green, that means joint design, primers and backing rod as standard.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. All of Greater London is in the ULEZ, and kerbside space in West Green 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 look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Share your working hours and any access restrictions
- Send asbestos survey details if the building is pre-2000

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Keep stones and debris out of open joint lines
- Report split or peeling joint sealant early
- Brief car park operatives to protect joint lines during winter clearance
- Put movement joints on the planned maintenance inspection round
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.

Where floor joints take the most wear near West Green
The 3 miles around West Green take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. 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.
On industrial estates such as Crusader Industrial Park (0.6 miles south of West Green), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Sites like St Ann's Hospital, under half a mile to the south of West Green, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Quoting for work in West Green
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- Working within restricted access windows
- Quantities, in metres or numbers
- Site requirements such as inductions and permits
- The product specified
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.
Before you send an enquiry
To price the job accurately, we need to understand the site. Useful things to include:

Surface by surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in.
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. We clean them back to sound material and prime where the manufacturer specifies before the bead goes in.
Do you need expansion joint sealing in West Green?
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.
Things that usually lead to an enquiry:
- Water dripping through deck or ramp joints
- Rain penetration at brick or block movement joints
- Layers of sealant in a movement joint
- Chipped joint edges on forklift routes
University campuses such as American University in London (2.1 miles south-west of West Green) have car parks, paved walkways and building elevations with movement joints.
Questions to ask before you book
- How long is the guarantee, and what does it include?
- Who will actually carry out the work
- Do they follow the manufacturer’s priming guidance?
- Their plan for phasing and protecting the area
