Why it’s worth doing now in Mottingham
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we’ll tell you honestly. Getting scaffold, permits or access booked in Mottingham takes effort, so it makes sense to deal with every failing joint while access is in place.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Expansion joint sealing for commercial buildings in Mottingham
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors on sites in Mottingham. The enquiries we see most involve previous reseals laid over old sealant and rain penetration at brick or block movement joints, across car park decks and ramps, blockwork control joints and cladding panel joints. Facilities teams, main contractors and managing agents in Mottingham tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Mottingham, as everywhere in London, access, loading and the ULEZ all come into the plan.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

FAQs: Mottingham
Can you cope with the access rules in a London building?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry.
Will you take on work at estates like Green Lane Business Park, close to Mottingham?
Yes. We cover Mottingham and the area around it, including industrial estates, business parks and retail parks such as Green Lane Business Park. Send details of the unit and the work through our quote form for a quick quote.
Why do our movement joints keep failing?
Normally the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.
What site paperwork can you supply?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Are you insured?
Yes. We’re fully insured, including public liability cover.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
What do you charge?
We don’t publish prices, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- A joint that has to be widened or re-detailed before it can work
- Cracking or settlement that calls for an engineer’s assessment
If you are not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

When to call us in Mottingham
Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.
If one of these sounds familiar, it’s time for a closer look:
- Joints where the bead has lost adhesion
- Rain penetration at brick or block movement joints
- Brittle, chalky sealant on external joints
- Previous reseals laid over old sealant
For buildings at a park such as Green Lane Business Park, 1.1 miles to the east of Mottingham, brick and panel movement joints are easy to forget until one leaks.

Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Send your site hours and access windows
- Tell us which areas need to stay in use
- Warn occupants and staff about the work
