What the job involves on each surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in, phased so parts of the car park stay open.
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. In Upper Edmonton, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Point out parking and an unloading spot
- Tell us which areas need to stay in use
- Move anything stored against the joints

Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Plan racking layouts so feet don’t land on a joint
- Keep traffic off new joints until the cure time is up
- Keep scrapers and ploughs from dragging across joint sealant
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
Floor joints on main traffic routes need watching more closely than the rest. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. A sound seal keeps the joint working.
Questions we’re asked in Upper Edmonton
Does your area include sites such as Compass West Industrial Estate, near Upper Edmonton?
Yes. Estates, retail parks and business parks around Upper Edmonton, Compass West Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is a hospital such as North Middlesex University Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you seal joints in cold or wet weather?
Outside work depends on conditions. Internal floor joints are far less affected.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Are expansion joints and movement joints the same thing?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
Signs you need expansion joint sealing in Upper Edmonton
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 typically get in touch after noticing one or more of the following:
- Water getting into the wall through a failed joint
- Movement joints with split or torn sealant
- Previous reseals laid over old sealant
- Sealant peeling off one face of the joint
Warehouse floors on estates like Compass West Industrial Estate, 0.6 miles to the south-east of Upper Edmonton, carry pallet trucks and forklifts over every saw-cut joint.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- Their pre-qualification and accreditations
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Is the sealant right for the movement and the substrate?
