Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Expansion joint sealing for commercial buildings in Mitcham
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we’ll confirm the choice in the quote. If you’re dealing with spalled or broken joint edges in floors and decks and previous reseals laid over old sealant, we can help, on brickwork movement joints, car park decks and ramps and podiums and floor movement joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Mitcham is the same: the right product in a properly prepared joint.
Areas such as a loading bay or car park deck in Mitcham normally have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Cost factors for movement joints
To price the job, we consider:
- How accessible the joints are
- Phasing around occupants
- The site’s rules and procedures
- Specialist products, such as fire-rated or hygienic sealants
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- Whether the building will be occupied during the work
- Any specification or named product
- When you need the work done
- Drawings or a marked-up plan, if available
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send photos by email.
From enquiry to sign-off
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. All of Greater London is in the ULEZ, and kerbside space in Mitcham can be scarce. 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.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Share your working hours and any access restrictions
- Explain the parking and delivery arrangements
- Flag any permit to work we’ll need

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
Advice
Questions about Mitcham
Is hospital work, at somewhere like The Wilson Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you take on jobs in Mitcham where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you guarantee expansion joint work?
The workmanship is guaranteed for 12 months from sign-off. Regular sweeping and inspection help the joints last.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
What we are called out for in Mitcham
Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes and it often shows on rushed work.
Things that usually lead to an enquiry:
- Hardened, cracked sealant on exposed facades
- Chipped joint edges on forklift routes
- Rain penetration at brick or block movement joints
- New sealant over old, now failing
For a centre such as Priory Retail Park, which lies north-west of Mitcham, the service yard and car park joints usually need attention first.
What your quote should include
- Their public liability cover
- Their approach to joint depth and backing
- Will CSCS-carded applicators be on site?
- Whether primer will be used where the manufacturer specifies it

Slabs, ramps and loading bays in Mitcham
The 3 miles around Mitcham 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. 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.
Another example is Beddington Lane Industrial Estate, 0.8 miles to the south-east of Mitcham, where floors and yards would be done in stages around the occupiers. Campuses like Kingston University Roehampton Vale Campus (5 miles north-west of Mitcham) mix old and new buildings, with movement joints wherever they meet.

Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Clear dirt from joint lines during routine cleaning
- Keep traffic off new joints until the cure time is up
- Report split or peeling joint sealant early
- Plan racking layouts so feet don’t land on a joint
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth. Keeping the area coned off until then avoids tyre marks and damage.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.
