Expansion joint sealing for East Finchley sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What affects the price in East Finchley
What shapes the price:
- The site’s rules and procedures
- Phasing around occupants
- Quantities, in metres or numbers
- Whether old sealant has to be cut out first
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Approximate linear metres or a joint schedule
- Asbestos survey details if the building is older
- Your programme or deadline
- Clear photographs of the problem areas
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or send details through our quote form.
Expansion joint sealing in East Finchley, done properly
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on podiums and floor movement joints, blockwork control joints and precast concrete panel joints, and the failures we’re asked to look at most are rain penetration at brick or block movement joints and brittle, chalky sealant on external joints. A single leaking joint is often how a building in East Finchley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around East Finchley, 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, so it pays to act early.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

East Finchley: questions and answers
Is Finchley Industrial Centre, near East Finchley, within your area?
Yes. Our area takes in East Finchley and its surroundings, with estates and business parks such as Finchley Industrial Centre included. Photos and a short description are enough for a first look.
Do you take on jobs in East Finchley where loading and access are tightly controlled?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email us. Photos, drawings or a joint schedule help us quote quickly.
How long does movement joint sealing take?
That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Common problems we fix in East Finchley
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. The product has to be suited to the traffic.
What tends to prompt an enquiry:
- Torn sealant in brick or block movement joints
- Water getting into the wall through a failed joint
- Brittle, chalky sealant on external joints
- Water dripping through deck or ramp joints
Another example is Friern Bridge Retail Park, 2 miles north-east of East Finchley, where floors and yards would be done in stages around the occupiers.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Whether primer will be used where the manufacturer specifies it
- Their pre-qualification and accreditations
- What the guarantee covers, and for how long
General trades versus a specialist
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
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 where general trades tend to cut corners.
How the job changes by surface
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 and a flexible sealant where the joint moves more.
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
