Why it’s worth doing now in St Ann's
A torn seal left alone normally gets worse. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. 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.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Expansion joint sealing for commercial buildings in St Ann's
Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. 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. Site teams most often ask us about hardened, cracked sealant on exposed facades and expansion joints filled with dirt and stones, across podiums and floor movement joints, car park decks and ramps and precast concrete panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in St Ann's, that means joint design, primers and backing rod as standard.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in St Ann's means thinking about access, loading times and the ULEZ as well as the joints.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need expansion joint sealing in St Ann's
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. A sealant that isn’t trafficable won’t last there.
It’s worth sending us details if you spot any of the following:
- Sealant peeling off one face of the joint
- New sealant over old, now failing
- Arrises breaking up along floor joints
- Water getting into the wall through a failed joint
Sites like St Ann's Hospital (to the south-west of St Ann's) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
What to look for in a quote
- Is the sealant right for the movement and the substrate?
- Whether primer will be used where the manufacturer specifies it
- Health and safety accreditation such as CHAS
- How joint depth will be controlled
Quoting for work in St Ann's
Before we quote, we look at:
- The total length or number of joints
- How accessible the joints are
- How much existing material needs removing
- The product specified
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 fixed quote once you have the details.
Sending details for a quote
A good diagnosis starts with the right details. Tell us:
- Whether the building will be occupied during the work
- The site address and postcode
- Specification clauses that apply
- How the joints are reached, and at what height
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Surface by surface
Brickwork and blockwork joints
Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, normally low-modulus, with backing rod setting the depth.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.
Honest limits
We check first that sealant really is the fix. It won’t put right:
- A joint that has to be widened or re-detailed before it can work
- Waterproofing layers buried beneath the sealant
- Movement on a scale no sealant is meant to absorb
Not sure which it is? You can call 01277 525 020 or send photos by email and we will tell you honestly before you book.

Your questions answered
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we will work to them.
Do you cover business parks and estates near St Ann's, such as Crusader Industrial Park?
Yes. We cover St Ann's and the area around it, including industrial estates, business parks and retail parks such as Crusader Industrial Park. Photos and a short description are enough for a first look.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.
Can you work on car park ramps and decks?
Yes. These joints take wheels, salt and water, so product choice matters and broken edges are flagged before sealing.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Do you work in St Ann's?
Yes. We cover St Ann's, and you can call 01277 525 020 or send photos by email to get started.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. All of Greater London is in the ULEZ, and kerbside space in St Ann's can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First, the joints are inspected for width, movement and the type of failure.
- A fixed quote follows, naming the sealant and its movement class.
- We strip out the old seal and prepare the faces.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- Tell staff and tenants when we will be in
- Send your site hours and access windows
- Agree which areas must stay open
