Expansion joint sealing in Deptford
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. If you’re dealing with torn sealant in brick or block movement joints and spalled or broken joint edges in floors and decks, we can put it right. One point of contact handles commercial sealant work in Deptford from the first photos 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. Joints are done in sections, with bays coned off one after another, so the site keeps operating.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

After the work
To get the most from the new sealant:
- Inspect exposed joints once the cold weather has passed
- Reopen bays and walkways only after the stated cure time
- Raise snow-clearing blades over deck joints where possible
- Act on the first tear or lifting edge rather than waiting
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

Our process
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 we check in with your contact before moving on to each new area. In Deptford, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We look at the joints, their width and how they’ve failed.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
What we need from you

Do you need expansion joint sealing in Deptford?
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way, so we check width and movement before quoting.
Most enquiries start with something like this:
- Previous reseals laid over old sealant
- Joints packed with grit and debris
- Water dripping through deck or ramp joints
- Rain penetration at brick or block movement joints
A campus such as University of Greenwich - Greenwich Campus, 0.9 miles to the east of Deptford, has long runs of movement joint in its buildings, decks and paving.
Questions to ask before you book
- Are they CHAS accredited or on Constructionline?
- Is the sealant right for the movement and the substrate?
- What level of public liability insurance do they hold?
- Their approach to joint depth and backing
What affects the price in Deptford
We price every job individually. The main factors are:
- Removal of failed or old sealant
- The product specified
- Site requirements such as inductions and permits
- The total length or number of joints
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- Whether an asbestos survey exists
- Whether the building will be occupied during the work
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Surface by surface
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.
Cladding panel joints
We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.
