Expansion joint sealing in Fortis Green: the local picture
In London, decks, bays and service yards normally have to keep running, so the work is broken into short sections agreed with the building manager. The 3 miles around Fortis Green take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.
Campuses like American University in London, 2.7 miles to the south-east of Fortis Green, mix old and new buildings, with movement joints wherever they meet. A healthcare site such as Nuffield Health Highgate Hospital (to the south of Fortis Green) depends on car parks, ramps and service yards whose joints take traffic all day.
Fortis Green is about 1 mile south-east of Finchley, in Greater London. We cover Fortis Green, with the same fixed quotes and 12-month guarantee as everywhere else.

How we handle expansion joint sealing in Fortis Green
For movement joints in Fortis Green, photos and approximate lengths are the best start. We’ll come and look where photos don’t show enough before issuing a fixed quote. To discuss the joints first, call 01277 525 020 or email the details over. Site teams most often ask us about new sealant over old, now failing and car park joints leaking onto vehicles below, on blockwork control joints, car park decks and ramps and cladding panel joints. One point of contact handles commercial sealant work in Fortis Green from the first photos to the final walk-round, for single jobs and planned programmes alike.
Around Fortis Green, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Fortis Green
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.
Typical triggers for a call:
- Debris jammed in movement joints
- Arrises breaking up along floor joints
- Movement joints with split or torn sealant
- Joints where the bead has lost adhesion
Another example is Brunswick Industrial Estate (2 miles north of Fortis Green), where floors and yards would be done in stages around the occupiers.
What to look for in a quote
- Can the work be phased to keep areas open?
- Whether their applicators hold CSCS cards
- How they handle RAMS and site documents
- Proof of insurance
When to bring in a specialist
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.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Questions we’re asked in Fortis Green
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. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as Friern Bridge Retail Park, near Fortis Green?
Yes. Estates, retail parks and business parks around Fortis Green, Friern Bridge Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Is movement joint sealing guaranteed?
A 12-month guarantee covers our workmanship, and we’re fully insured for public liability. Regular sweeping and inspection help the joints last.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you cover Fortis Green?
Yes. Fortis Green falls within our area, and the simplest way to start is to give us a call on 01277 525 020 or send details through our quote form.
On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Make sure the joints can be reached

For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
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 Fortis Green can sit alongside others in a wider programme.
Different surfaces, different methods
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen.
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves.
Why deal with it now?
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. Getting scaffold, permits or access booked in Fortis Green takes effort, so it makes sense to deal with every failing joint while access is in place.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.
