Expansion joint sealing for businesses in Cannon Hill
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Questions about Cannon Hill
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for
Is a hospital such as New Victoria Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Does the weather affect joint sealing?
Weather matters for any external joint: rain, frost and condensation all stop sealant bonding. Indoor joints can normally carry on regardless.
Can you quote from photos?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Is any job too small?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Which product is best for expansion joints?
Movement capability matters most, classified under BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Joints that move: notes for Cannon Hill
The 3 miles around Cannon Hill take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager.
Phasing is what makes joint work possible on busy sites such as Beverley Trading Estate (1.1 miles south of Cannon Hill): one bay, aisle or car park row at a time. Hospital campuses such as New Victoria Hospital (to the north-west of Cannon Hill) grow in stages, leaving movement joints wherever new blocks meet old.
Cannon Hill is about 1 mile north-west of Morden, in Greater London. Anywhere in SW20, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

Our process
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 each bead is tooled to a neat concave finish. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied 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
- Tell staff and tenants when we will be in
- Arrange parking or a loading space
- Agree which areas must stay open

Do you need expansion joint sealing in Cannon Hill?
Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. BS EN ISO 11600 classifies building sealants by movement capability.
It’s worth sending us details if you spot any of the following:
- Damp inside where a wall movement joint has failed
- Joints packed with grit and debris
- Chipped joint edges on forklift routes
- Movement joints with split or torn sealant
Retail centres such as Priory Retail Park, 2 miles to the north-east of Cannon Hill, have floors, service yards and car parks with joints under constant traffic.
What to look for in a quote
- The named product and why it was chosen
- Their plan for phasing and protecting the area
- Their pre-qualification and accreditations
- Who will actually carry out the work
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Changing the joint layout or spacing of a structure
- Crumbling edges that would give a new bead nothing sound to grip
- Leaks coming from the membrane rather than the joint seal
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think before you book.
What we seal
- Blockwork control joints
- Precast concrete panel joints
- Car park decks and ramps
- Podiums and floor movement joints
- Brickwork movement joints

What sets the cost
These are the things that shape the price:
- Whether old sealant has to be cut out first
- Access and working height
- Whether the work must be split into stages
- Specialist products, such as fire-rated or hygienic sealants
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
