About our expansion joint sealing in Lee
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. Most enquiries involve debris jammed in movement joints and expansion joints split through the centre of the bead, on cladding panel joints, precast concrete panel joints and blockwork control joints. A single leaking joint is often how a building in Lee 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.
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.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What the job involves on each surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Brickwork and blockwork joints
Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

FAQs: Lee
Do you cover business parks and estates near Lee, such as Chiltonian Industrial Estate?
Yes. Our area takes in Lee and its surroundings, with estates and business parks such as Chiltonian Industrial Estate included. A few photos and the unit address let us price the work.
Is a hospital such as Blackheath Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you use silicone or polyurethane in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks normally need a polyurethane unless the specification names something else.
Can a joint be sealed if the edges are broken?
The edges have to be sound. Where they’ve broken up, we will tell you they need repairing first so you’re not paying for a bead that won’t hold.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Traffic, movement and joints around Lee
Less than 3 miles from Lee there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. 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.
At a retail site such as Lewisham Shopping Centre, 1.1 miles north-west of Lee, trolleys, cages and cars run over floor and slab joints all day. For an occupier at a site such as Chiltonian Industrial Estate, which lies south of Lee, the joints at loading doors and dock levellers usually see the hardest wear. Large sites such as Blackheath Hospital, 0.8 miles to the north of Lee, have car parks, service roads and long elevations with movement joints in brick and panels.
Lee is about 2 miles south of Greenwich, in Greater London. If you’re looking for expansion joint sealing in Lee, we can help. Lee is one of 764 places in Greater London on our list for movement joints. Sites around London have their own page, about 6 miles away.

Landmarks near Lee

From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a job in Lee, 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.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Send your site hours and access windows
- Make sure the joints can be reached

What happens if it’s left?
A like-for-like reseal of a joint that keeps splitting rarely lasts. If the joint is too narrow or the product wrong for the movement, it needs a different approach, and we’ll 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.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Looking after the joints
After handover, a little attention goes a long way:
- Clear dirt from joint lines during routine cleaning
- Avoid parking heavy plant or pallets on joint lines
- Keep product details with the building records for the next reseal
- Inspect movement joints alongside other routine building checks
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, speak to us on 01277 525 020 or email drawings and photos with photographs.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Crumbling edges that would give a new bead nothing sound to grip
- Joints too narrow for the movement, which need redesigning by the engineer
- Waterproofing layers buried beneath the sealant
If you’re not sure, just speak to us on 01277 525 020 or send photos by email and we will give you a straight answer.
