Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Aftercare for building managers
A few simple habits keep the new joints working:
- Put movement joints on the planned maintenance inspection round
- Report split or peeling joint sealant early
- Check joints after long freezing spells
- Keep product details with the building records for the next reseal
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
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. Resealing promptly prevents internal damage.

One point of contact handles commercial sealant work in South Wimbledon from the first photographs to the final walk-round, whether it’s one building or several.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Common questions from South Wimbledon clients
Would you work within a site like St George's Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Do you take on jobs in South Wimbledon where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Can you seal car park deck joints?
Yes. We use a sealant designed for wheel loads and the expected movement.
How long will the joint resealing take?
Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote along with the phasing plan.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
How do we ask for a quote?
The quote form is the simplest route, though you can also phone 01277 525 020 or email the details over. Include photos or drawings if you have them.
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Let us know about inductions and permits
- Make sure the joints can be reached

When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:
- Concrete or masonry repairs along the arrises
- Cracking or settlement that calls for an engineer’s assessment
- Changing the joint layout or spacing of a structure
If in doubt, call 01277 525 020 or email the details over and we will say what we think.

Do you need expansion joint sealing in South Wimbledon?
The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.
Any of the following is a good reason to get the joints checked over:
- Car park joints leaking onto vehicles below
- Sealant pulling off the joint face
- Layers of sealant in a movement joint
- Weathered movement joint sealant that no longer flexes
A campus such as Kingston University Roehampton Vale Campus (to the north-west of South Wimbledon) has long runs of movement joint in its buildings, decks and paving.
What to look for in a quote

South Wimbledon has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
Phasing is what makes joint work possible on busy sites such as Lombard Business Park (0.7 miles south-east of South Wimbledon): one bay, aisle or car park row at a time.
