How we handle expansion joint sealing in Cooling Street
Brickwork and blockwork walls have vertical movement joints at intervals. Once the seal fails, rain reaches the cavity and the joint can no longer close. 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 are dealing with rain penetration at brick or block movement joints and joints where the bead has lost adhesion, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Cooling Street from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In and around smaller places like Cooling Street, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Traffic, movement and joints around Cooling Street
With the shore within about 3 miles, Cooling Street counts as a coastal location. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. Rainfall across the South East, Cooling Street included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.
For a school such as Cliffe Woods Primary School, playground and building joints can be done in the holidays. Campuses like University of Greenwich - Medway (3.3 miles south of Cooling Street) mix old and new buildings, with movement joints wherever they meet.

Surface by surface
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, typically low-modulus, with backing rod setting the depth.
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.

Owners, agents and contractors
We work for building owners and managing agents on everything from one building to a spread of sites around Cooling Street. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Cooling Street are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Tell us what induction or permit system the site runs
- Send any specification or drawings in advance

Quotes
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. For smaller jobs, photos and a description will do.

After the work
For the best life from the joints:
- Clear dirt from joint lines during routine cleaning
- Treat a small split as a warning, not a cosmetic issue
- Look over external and deck joints after a hard winter
- Raise snow-clearing blades over deck joints where possible
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check. If anything looks wrong, speak to us on 01277 525 020 or use the quote form with photos.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.
Your questions answered
Is a smaller place like Cooling Street outside your area?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you take on work at healthcare sites like French Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it.
What guarantee do you give on joint sealing?
It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Signs you need expansion joint sealing in Cooling Street
The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.
Typical triggers for a call:
- Chipped joint edges on forklift routes
- Car park joints leaking onto vehicles below
- Hardened, cracked sealant on exposed facades
- Joints where the bead has lost adhesion
On industrial estates such as Nuralite Industrial Estate (2.7 miles west of Cooling Street), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
