Floors, slabs and movement joints in Widmore
Widmore has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment. London car parks, loading bays and podium decks often can’t close for long, so the work is broken into short sections agreed with the building manager.
University campuses such as University of Greenwich - Avery Hill (3.4 miles north of Widmore) have car parks, paved walkways and building elevations with movement joints. For buildings at a park such as Chartwell Business Centre (0.5 miles west of Widmore), brick and panel movement joints are easy to forget until one leaks.
Widmore is about 1 mile east of Bromley, in Greater London. We cover commercial sites throughout Widmore, whether it’s a single job or part of a planned programme. We work across 764 places in Greater London, large and small. London is covered too, around 9 miles from Widmore.

What’s near Widmore
Locally, jobs take us to sites close to Bird In Hand Public House, St George's and Jubilee Country Park and the streets around them. There’s a railway station in Widmore itself: Bickley station. Nearby you will also find Bridgeways Day Hospital (1 mile south) and The Mall (1.3 miles west). Not far away are Summer Hill and The Tarn.
On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. In Widmore, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- First the joints are inspected, widths measured and the type of failure noted.
- 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.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Getting the site ready
- Confirm the product named in the specification
- Flag any permit to work we’ll need
- For older buildings, check the asbestos register before work

Common problems we fix in Widmore
Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way.
Any of the following is a good reason to get the joints checked over:
- Chipped joint edges on forklift routes
- Expansion joints split through the centre of the bead
- Hardened, cracked sealant on exposed facades
- Car park joints leaking onto vehicles below
Hospitals like Sloane Hospital (2.3 miles west of Widmore) have multi-storey or surface car parks whose joints carry vehicles round the clock.
Before you book anyone
- Their pre-qualification and accreditations
- Is the sealant right for the movement and the substrate?
- Whether old or failed sealant will be cut out, not overlaid
- What site paperwork they can supply
What sealant work can’t fix
Before quoting, we check that sealant is the right answer. It won’t put right:
- Movement on a scale no sealant is meant to absorb
- Waterproofing layers buried beneath the sealant
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Maintenance after handover
For the best life from the joints:
- Keep racking legs and heavy point loads off floor joints
- Report split or peeling joint sealant early
- Leave barriers in place until fresh joint sealant has cured
- Put movement joints on the planned maintenance inspection round
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.
Other services in Widmore
Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Common questions from Widmore clients
Can you work at a site such as Chartwell Business Centre, by Widmore?
Yes. Our area takes in Widmore and its surroundings, with estates and business parks such as Chartwell Business Centre included. A few photographs and the unit address let us price the work.
Is hospital work, at somewhere like Sloane Hospital, something you do?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Does the weather affect joint sealing?
Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.
What will the job cost?
Each job is quoted on its own details. For yours, ring 01277 525 020 or send details through our quote form with a description of the work.
Is movement joint sealing guaranteed?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
