Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Expansion joint sealing for commercial buildings in Riddlesdown
Brickwork and blockwork walls have vertical movement joints at intervals. 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. If you have chipped joint edges on forklift routes and sealant peeling off one face of the joint, we can put it right, on brickwork movement joints, blockwork control joints and podiums and floor movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Riddlesdown is the same: the right product in a properly prepared joint.
London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Riddlesdown, as everywhere in London, access, loading and the ULEZ all come into the plan.
A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or send photos by email and we will arrange a return visit.

Joints that move: notes for Riddlesdown
At least three named trading, business or retail sites lie within about 3 miles of Riddlesdown. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards typically have to keep running, so the work is broken into short sections agreed with the building manager.
In a school such as Harris Primary Academy Kenley, movement joints in brick, block and hall floors tend to be forgotten until they leak. For a job in Riddlesdown, we confirm the ULEZ-compliant vehicle, the loading arrangements and where materials go before we arrive. Hospital campuses such as Purley War Memorial Hospital (1 mile north-west of Riddlesdown) grow in stages, leaving movement joints wherever new blocks meet old.

Questions about Riddlesdown
Is a hospital such as Purley War Memorial Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do you offer coloured sealant?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Can you work while the building is occupied?
Normally, yes. Phased work can be planned so areas stay in use.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
When something else is needed
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Movement on a scale no sealant is meant to absorb
- Changing the joint layout or spacing of a structure
- Leaks coming from the membrane rather than the joint seal
If in doubt, phone 01277 525 020 or email the details over and we will say what we think.
Surfaces we seal
- Blockwork control joints
- Brickwork movement joints

Owners, agents and contractors
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Riddlesdown can sit alongside others in a wider programme.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.
Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Leave barriers in place until fresh joint sealant has cured
- Put movement joints on the planned maintenance inspection round
- Plan racking layouts so feet don’t land on a joint
- Report split or peeling joint sealant early
Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. 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. Keeping the filler or sealant sound protects the floor.
Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. 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 look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- 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
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
- Tell staff and tenants when we’ll be in
Getting a fixed quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Why it’s worth doing now in Riddlesdown
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. Full removal and preparation is in every quote. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why appoint us
