How we handle expansion joint sealing in St John Street area
Brickwork and blockwork walls have vertical movement joints at intervals, and they’re easy to miss until the sealant fails. 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 with primer where the maker calls for it. If you have leaks through car park deck joints onto the level below and previous reseals laid over old sealant, we can put it right. Most enquiries from St John Street area start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Small units near places like St John Street area are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What happens if it’s left?
Resealing is normally the answer, not replacing the element. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. In a smaller place such as St John Street area, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Damaged metal nosings or cover plates over a joint
- A joint that has to be widened or re-detailed before it can work
If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think.
Surfaces we seal
- Cladding panel joints
- Blockwork control joints
- Podiums and floor movement joints
- Car park decks and ramps
- Brickwork movement joints
- Precast concrete panel joints
Aftercare for building managers
To get the most from the new sealant:
- Note which joints were done, when, and with what
- Brief car park operatives to protect joint lines during winter clearance
- Inspect exposed joints once the cold weather has passed
- Include every elevation and deck joint in periodic inspections
Fresh joint sealant needs its full cure time before it takes traffic or water. 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.
On a multi-storey car park, a failed joint typically shows up as a leak onto the deck underneath. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.
