About our expansion joint sealing in Lewisham
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on car park decks and ramps, precast concrete panel joints and blockwork control joints, and what we’re called in for most is expansion joints split through the centre of the bead and weathered movement joint sealant that no longer flexes. One point of contact handles commercial sealant work in Lewisham from the first photos to the final walk-round, for single jobs and planned programmes alike.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Your questions answered
Is hospital work, at somewhere like University Hospital Lewisham, something you do?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you take on jobs in Lewisham where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Which sealant will you use?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Can you seal car park deck joints?
Yes. These joints take wheels, salt and water, so product choice matters, and we will tell you if any edges need repairing first.
Why do our movement joints keep failing?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing since each needs a different fix.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
Slabs, ramps and loading bays in Lewisham
London car parks, loading bays and podium decks often can’t close for long, so the work is broken into short sections agreed with the building manager. Lewisham has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.
For a centre such as Lewisham Shopping Centre, less than half a mile north-west of Lewisham, the service yard and car park joints typically need attention first. For an estate such as University Hospital Lewisham (0.6 miles south-west of Lewisham), the joints in ramps, decks and long building elevations all need attention over time. Campuses like University of Greenwich - Greenwich Campus (to the north of Lewisham) mix old and new buildings, with movement joints wherever they meet.

What else we do in Lewisham
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.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Cost factors for movement joints
Your fixed quote is built from the real scope. It takes account of:
- Phasing around occupants
- How much existing material needs removing
- Site requirements such as inductions and permits
- How accessible the joints are
Pricing movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.
Details that help us quote
There’s no need for a formal survey. These details are enough to start:
- The asbestos register, for older buildings
- A wide shot and a close-up of the area
- Access details, including height
- Any dates the work must fit around
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or email a schedule or drawings.
Why deal with it now?
Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. Urgent joints now, the rest later, is often the sensible plan. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Changing the joint layout or spacing of a structure
- Cracking or settlement that calls for an engineer’s assessment

Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- 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.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Explain the parking and delivery arrangements
- Share your working hours and any access restrictions
