About our expansion joint sealing in Edmonton
We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic, and we’ll confirm the choice in the quote. Site teams most often ask us about car park joints leaking onto vehicles below and damp inside where a wall movement joint has failed, on car park decks and ramps, precast concrete panel joints and blockwork control joints. One point of contact handles commercial sealant work in Edmonton from the first photos to the final walk-round, whether it’s one building or several.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Can you work at a site such as Edmonton Green Shopping Centre, by Edmonton?
Yes, sites like Edmonton Green Shopping Centre are within our area, along with the rest of Edmonton. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Who decides which product is used?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. All of Greater London is in the ULEZ, and kerbside space in Edmonton can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We look at the joints, their width and how they’ve failed.
- 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.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
What we need from you
- Flag any permit to work we will need
- Arrange parking or a loading space
- Tell us your opening times and when work is allowed

Related advice
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Work for main contractors and building owners
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Edmonton can sit alongside others in a wider programme.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Quoting for work in Edmonton
Each job is priced on its own details. The things that drive the figure:
- Joint width, depth and condition
- Quantities, in metres or numbers
- Access and working height
- Which sealant the job calls for
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
However big the job, these details speed things up:
- How the joints are reached, and at what height
- What the building is and how it’s used
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Maintenance after handover
Once the work is signed off, these steps help:
- Avoid parking heavy plant or pallets on joint lines
- Put movement joints on the planned maintenance inspection round
- Look over external and deck joints after a hard winter
- Act on the first tear or lifting edge rather than waiting
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, give us a call on 01277 525 020 or send details through our quote form with photos.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Sealing early protects the edges.
Where floor joints take the most wear near Edmonton
Less than 3 miles from Edmonton there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. London car parks, loading bays and podium decks often can’t close for long, so joints are sealed in sections with each area handed back once cured.
Another example is Dominion Business Park, which lies east of Edmonton, where floors and yards would be done in stages around the occupiers. Schools such as Brettenham Primary School have movement joints in their walls and floors that are easy to overlook. Places like Edmonton Green Shopping Centre, less than half a mile to the north-east of Edmonton, put trolleys over floor joints inside and cars over slab joints outside.

Leave it or put it right?
Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. We’ll flag where edges need repair before sealing. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
