Signs you need expansion joint sealing in Mortlake
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.
Any of the following is a good reason to get the joints checked over:
- Sealant pulling off the joint face
- Arrises breaking up along floor joints
- Leaks through car park deck joints onto the level below
- Joints packed with grit and debris
Retail parks like Kew Retail Park (1 mile north-west of Mortlake) have long runs of car park and yard joints taking daily traffic.
Questions to ask before you book
- How they’ll work around occupants
- Health and safety accreditation such as CHAS
- Do they follow the manufacturer’s priming guidance?
- The named product and why it was chosen
Expansion joint sealing for commercial buildings in Mortlake
If you need expansion joint sealing in Mortlake, start with photographs and joint lengths. We’ll come and look where photographs don’t show enough, then send a fixed quote that names the sealant. You can also call 01277 525 020 or email drawings and photos to talk the joints through. If you are dealing with expansion joints filled with dirt and stones and joints where the bead has lost adhesion, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Mortlake it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Mortlake, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What happens if it’s left?
A torn seal left alone usually gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Failed sealant in a building in Mortlake can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.

What sealant work can’t fix
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Concrete or masonry repairs along the arrises
- Movement on a scale no sealant is meant to absorb
- Leaks coming from the membrane rather than the joint seal
If you’re not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer.

On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a job in Mortlake, 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.
- First, the joints are inspected for width, movement and the type of failure.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- 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.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Send your site hours and access windows
- Send asbestos survey details if the building is pre-2000
- Tell staff and tenants when we’ll be in

How the job changes by surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.
Joints between different materials
Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement.
Keeping the joints sound
Once the work is signed off, these steps help:
- Reopen bays and walkways only after the stated cure time
- Include every elevation and deck joint in periodic inspections
- Inspect exposed joints once the cold weather has passed
- Report split or peeling joint sealant early
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.
Common questions from Mortlake clients
Do you take on work at healthcare sites like Barnes Hospital?
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.
Can you work at a site such as Kew Retail Park, by Mortlake?
Yes, sites like Kew Retail Park are within our area, along with the rest of Mortlake. Photos and a short description are enough for a first look.
What causes movement joint sealant to fail?
Normally the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
