Expansion joint sealing in Wandsworth, done properly
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you have spalled or broken joint edges in floors and decks and water dripping through deck or ramp joints, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Wandsworth it comes down to the same thing: the right product in a properly prepared joint.
Areas such as a loading bay or car park deck in Wandsworth typically have to stay in use. We work through joints a section at a time, closing small areas in turn.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. All of Greater London is in the ULEZ, and kerbside space in Wandsworth can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Tell us what induction or permit system the site runs
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints

Honest limits
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Cracking or settlement that calls for an engineer’s assessment
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Proprietary pre-formed expansion joint systems
If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.
Joints and surfaces we work on
- Precast concrete panel joints
- Brickwork movement joints
- Podiums and floor movement joints

What affects the price in Wandsworth
A fixed quote reflects the actual work. It takes account of:
- How much existing material needs removing
- Location, for remote and island sites
- Which sealant the job calls for
- How accessible the joints are
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:

Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Plan racking layouts so feet don’t land on a joint
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Note which joints were done, when, and with what
- Report split or peeling joint sealant early
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.
External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.
What happens if it’s left?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
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.

Expansion joint sealing around Wandsworth: what changes locally
Few London car parks or loading bays can be taken out of use for more than a short spell, so we seal in sections and hand areas back as each cures. Wandsworth has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
For buildings at a park such as Chartwell Business Park, 0.5 miles to the north of Wandsworth, brick and panel movement joints are easy to forget until one leaks. Phasing is what makes joint work possible on busy sites such as Hurlingham Business Park (0.8 miles north of Wandsworth): one bay, aisle or car park row at a time. Hospital campuses such as Royal Hospital for Neuro-Disability (to the west of Wandsworth) grow in stages, leaving movement joints wherever new blocks meet old.
Wandsworth is about 3 miles south-west of Brompton, in Greater London. Our applicators travel to Wandsworth for work on movement joints, handled exactly as we handle every other area. Across Greater London, 764 places are covered, including Wandsworth.

Questions we’re asked in Wandsworth
Will you take on work at estates like Chartwell Business Park, close to Wandsworth?
Yes, sites like Chartwell Business Park are within our area, along with the rest of Wandsworth. A few photographs and the unit address let us price the work.
Can you cope with the access rules in a London building?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
What causes movement joint sealant to fail?
Typically the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing, rather than replacing like for like.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Do you work in Wandsworth?
Yes. We cover Wandsworth, and you can call the office on 01277 525 020 or email drawings and photos to get started.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
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.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
