About our expansion joint sealing in Walworth
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. We work on cladding panel joints, car park decks and ramps and brickwork movement joints, and the failures we are asked to look at most are car park joints leaking onto vehicles below and damp inside where a wall movement joint has failed. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Walworth is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Areas such as a loading bay or car park deck in Walworth usually 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.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. All of Greater London is in the ULEZ, and kerbside space in Walworth 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 photographs, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- 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.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Flag any permit to work we’ll need
- Tell staff and tenants when we’ll be in
- For older buildings, check the asbestos register before work

Related advice
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Include every elevation and deck joint in periodic inspections
- Keep product details with the building records for the next reseal
- Inspect exposed joints once the cold weather has passed
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.
Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.

Expansion joint sealing around Walworth: what changes locally
At least three named trading, business or retail sites lie within about 3 miles of Walworth. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. London car parks, loading bays and podium decks often can’t close for long, so we seal in sections and hand areas back as each cures.
In a school such as Robert Browning Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. University campuses such as London South Bank University (0.8 miles north-west of Walworth) have car parks, paved walkways and building elevations with movement joints.
Walworth is about 1 mile south of London, in Greater London. We send applicators to Walworth for movement joints. Our Greater London coverage takes in 764 places, from busy centres to rural villages.

Common problems we fix in Walworth
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Any of the following is a good reason to get the joints checked over:
- Car park joints leaking onto vehicles below
- Rain penetration at brick or block movement joints
- Torn sealant in brick or block movement joints
- Previous reseals laid over old sealant
Hospital campuses such as Guy's Hospital, 0.9 miles north of Walworth, grow in stages, leaving movement joints wherever new blocks meet old.
What your quote should include
- Proof of insurance
- How the existing material will be dealt with
- How joint depth will be controlled
- Health and safety accreditation such as CHAS
Leave it or put it right?
Leaving a failed movement joint rarely stays a small problem. 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. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Pricing movement joints depends on how many there are, their condition and the access. Call for a quote.

Walworth: questions and answers
Will you take on work at estates like Burgess Business Park, close to Walworth?
Yes. We cover Walworth and the area around it, including industrial estates, business parks and retail parks such as Burgess Business Park. A few photos and the unit address let us price the work.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Can the building stay open while you work?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can you quote from photographs?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Do you cover Walworth?
Yes. We cover Walworth, and you can give us a call on 01277 525 020 or send photos by email to get started.
Doing it in-house
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.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
How the job changes by surface
Brickwork and blockwork joints
Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit.
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.
