Expansion joint sealing in Sandgate
A movement joint only works while its seal does. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. We work on car park decks and ramps, blockwork control joints and brickwork movement joints, and the failures we are asked to look at most are weathered movement joint sealant that no longer flexes and damp inside where a wall movement joint has failed. One point of contact handles commercial sealant work in Sandgate from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Smaller community and commercial buildings around Sandgate have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Surface by surface
Joints between different materials
Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement, with primer where specified.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.
Diagnose, treat, sign off
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Sandgate can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.

When to call us in Sandgate
Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again, so we check width and movement before quoting.
Common reasons buildings call us in:
- Hardened, cracked sealant on exposed facades
- Debris jammed in movement joints
- Sealant pulling off the joint face
- Car park joints leaking onto vehicles below
Another example is Golden Valley Shopping Centre, 0.6 miles to the north of Sandgate, where floors and yards would be done in stages around the occupiers.
What to look for in a quote
- What the guarantee covers, and for how long
- Which product they’ll use, and why it suits the joint
- Will CSCS-carded applicators be on site?
- Health and safety accreditation such as CHAS
What happens if it’s left?
Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Converted and older buildings near places like Sandgate tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Pricing movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

FAQs: Sandgate
Does your area include sites such as Shorncliffe Industrial Estate, near Sandgate?
Yes. We cover Sandgate and the area around it, including industrial estates, business parks and retail parks such as Shorncliffe Industrial Estate. Photos and a short description are enough for a first look.
Is Sandgate off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Is movement joint sealing guaranteed?
Our workmanship on movement joints carries a 12-month guarantee. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Are you fully insured?
Yes. We’re fully insured, and the certificate can go with your quote.
