About our expansion joint sealing in The Hale
Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. The enquiries we see most involve joints where the bead has lost adhesion and new sealant over old, now failing, on brickwork movement joints, blockwork control joints and podiums and floor movement joints. A specialist sealant contractor works differently from a general builder: in The Hale, that means joint design, primers and backing rod as standard.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Signs you need expansion joint sealing in The Hale
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.
Clients normally get in touch after noticing one or more of the following:
- Spalled or broken joint edges in floors and decks
- Previous reseals laid over old sealant
- Water dripping through deck or ramp joints
- Joints where the bead has lost adhesion
Warehouse floors on estates like Mill Hill Industrial Estate (to the south-east of The Hale) carry pallet trucks and forklifts over every saw-cut joint.

Questions we are asked in The Hale
Do you take on jobs in The Hale where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry.
Is a hospital such as Edgware Community Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you seal car park deck joints?
Yes. Tell us how the car park is used and which areas must stay open.
Can you handle several sites?
Yes. Several buildings can share a single quote, with one point of contact.
What sealant do you use in movement joints?
It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane.
Where floor joints take the most wear near The Hale
The 3 miles around The Hale take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager.
University campuses such as Middlesex University (1.8 miles south-east of The Hale) have car parks, paved walkways and building elevations with movement joints. Sites like Edgware Community Hospital, 1 mile to the south-west of The Hale, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Different surfaces, different methods
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.
How the quote is worked out
Each job is priced on its own details. The things that drive the figure:
- The site’s rules and procedures
- Working within restricted access windows
- Access and working height
- Quantities, in metres or numbers
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.
What to include in your enquiry
There’s no need for a formal survey. These details are enough to start:
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
- What the building is and how it’s used
- Photos of the joints, close up and from further back
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.
Diagnose, treat, sign off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Before we start on site
- Have the specification and drawings to hand
- Send your site hours and access windows
- Agree which areas must stay open
Request a quote
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Keeping the joints sound
A few simple habits keep the new joints working:
- Avoid parking heavy plant or pallets on joint lines
- Keep stones and debris out of open joint lines
- Act on the first tear or lifting edge rather than waiting
- Note which joints were done, when, and with what
Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort so you can prioritise and budget. We can suggest an order, worst joints first.
