Expansion joint sealing in Lower Cox Street, done properly
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. 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. Site teams most often ask us about layers of sealant in a movement joint and sealant peeling off one face of the joint, on brickwork movement joints, blockwork control joints and cladding panel joints.

Smaller community and commercial buildings around Lower Cox Street have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Every job we finish is backed by a 12-month workmanship guarantee, in Lower Cox Street as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Cracking or settlement that calls for an engineer’s assessment
- Joints too narrow for the movement, which need redesigning by the engineer
- Waterproofing layers buried beneath the sealant

Building owners, agents and FMs in Lower Cox Street
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Common problems we fix in Lower Cox Street
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
Clients normally get in touch after noticing one or more of the following:
- Damp inside where a wall movement joint has failed
- Brittle, chalky sealant on external joints
- New sealant over old, now failing
- Car park joints leaking onto vehicles below
Another example is Parkwood Shopping Centre, 2.1 miles north of Lower Cox Street, where floors and yards would be done in stages around the occupiers.
What your quote should include
- Health and safety accreditation such as CHAS
- Whether primer will be used where the manufacturer specifies it
- Whether old or failed sealant will be cut out, not overlaid
- The named product and why it was chosen
On site: what to expect
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Lower Cox Street, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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 which areas need to stay in use
- Explain the parking and delivery arrangements

Joints that move: notes for Lower Cox Street
The 3 miles around Lower Cox Street take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Rainfall across the South East, Lower Cox Street included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.
A healthcare site such as KIMS Hospital, 2.8 miles south-west of Lower Cox Street, depends on car parks, ramps and service yards whose joints take traffic all day. University campuses such as Canterbury Christ Church University, 5 miles to the south-east of Lower Cox Street, have car parks, paved walkways and building elevations with movement joints.

Leave it or put it right?
Resealing is typically the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. For buildings around smaller places like Lower Cox Street, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

FAQs: Lower Cox Street
Can you work at a site such as Hempstead Valley Shopping Centre, by Lower Cox Street?
Yes, sites like Hempstead Valley Shopping Centre are within our area, along with the rest of Lower Cox Street. Send details of the unit and the work through our quote form for a quick quote.
Is hospital work, at somewhere like KIMS Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is movement joint sealing guaranteed?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can staff carry on working while you are here?
Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.
What exactly is a movement joint?
They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Different surfaces, different methods
Internal floor movement joints
Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in and flag any joint that seems undersized.
