About our expansion joint sealing in Blendon
Our movement joint work takes in walls, panels, decks and floors: 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. We work on blockwork control joints, car park decks and ramps and cladding panel joints, and what we are called in for most is damp inside where a wall movement joint has failed and joints packed with grit and debris. One point of contact handles commercial sealant work in Blendon from the first photos to the final walk-round, for single jobs and planned programmes alike.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Blendon, as everywhere in London, access, loading and the ULEZ all come into the plan.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Blendon
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Which sealant the job calls for
- Whether the work must be split into stages
- How much there is to seal
- Location, for remote and island sites
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Where the site is, with the postcode
- The product your specification calls for
- Photos of the joints, close up and from further back
- The asbestos register, for older buildings
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Questions about Blendon
Can you work at a site such as Old Bexley Business Park, by Blendon?
Yes, sites like Old Bexley Business Park are within our area, along with the rest of Blendon. A few photos and the unit address let us price the work.
Can you work on a hospital site such as Queen Mary's Hospital?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Do you work in Blendon?
Yes. We take on work across Blendon, and the same phone number covers every area.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What’s the difference between an expansion joint and a movement joint?
The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably, and the sealing method is much the same.
What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:
- Changing the joint layout or spacing of a structure
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Movement on a scale no sealant is meant to absorb
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.
Joints and surfaces we work on
- Precast concrete panel joints

Common problems we fix in Blendon
When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons.
Things that normally lead to an enquiry:
- Torn sealant in brick or block movement joints
- Sealant peeling off one face of the joint
- Leaks through car park deck joints onto the level below
- Rain penetration at brick or block movement joints
Hospitals like Queen Mary's Hospital, 2.1 miles south of Blendon, have multi-storey or surface car parks whose joints carry vehicles round the clock.
Questions to ask before you book
- Their pre-qualification and accreditations
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether primer will be used where the manufacturer specifies it
- Proof of insurance
On site: what to expect
Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. All of Greater London is in the ULEZ, and kerbside space in Blendon can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces.
- 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.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Let us know about inductions and permits
- Explain the parking and delivery arrangements

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Warehouse floors and decks around Blendon
Blendon has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards typically have to keep running, so joints are sealed in sections with each area handed back once cured.
On a site such as Old Bexley Business Park, 1.3 miles to the east of Blendon, the movement joints are in car park slabs, paving and building elevations. Retail centres such as Broadway Shopping Centre (to the north-east of Blendon) have floors, service yards and car parks with joints under constant traffic.
Blendon is about 1 mile south-east of Welling, in Greater London. We cover Blendon and the rest of Greater London, with the same fixed quotes and 12-month guarantee as everywhere else. Blendon is one of 764 places in Greater London on our list for movement joints. We also cover London, around 10 miles from Blendon.
We cover the DA5, DA15 and DA6 postcode districts for movement joints. We cover commercial and managed buildings on Penn Lane, Hurst Road and Brook Lane and the roads nearby. You will find Blendon on or near the A221, so getting applicators and materials to site is simple. We also cover Bexley (1 mile south-east), Crook Log (1 mile north), Welling (1 mile north-west), Upton (1 mile north-east) and Bexleyheath (1 mile north-east) for movement joints. Further afield, our area takes in London (10 miles west), City of Westminster (13 miles west), Marylebone (13 miles north-west), Kensington (14 miles west), St Pancras (12 miles north-west) and Shoreditch (10 miles north-west).
Local landmarks in Blendon
Locally, jobs take us to sites close to Danson Park, The Royal Oak Public House and Hurst Primary School and the streets around them. Blendon’s nearest station is Albany Park station, about 0.8 miles south. Nearby you’ll also find Metropolitan Police Museum (1.3 miles south-west) and Bexley Hospital (0.8 miles north-east). For a walk, there’s Wansunt Pit and Summer Hill.
Maintenance after handover
For the best life from the joints:
- Note which joints were done, when, and with what
- Keep stones and debris out of open joint lines
- Plan racking layouts so feet don’t land on a joint
- Treat a small split as a warning, not a cosmetic issue
Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. Keeping the seal sound avoids all of that.
Commercial clients in Blendon
