Expansion joint sealing across Broom Hill
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
How a job runs
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. In Broom Hill, 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.
- You receive a fixed quote stating the product and the movement it is rated for.
- 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.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Move anything stored against the joints
Quotes
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Expansion joint sealing for commercial buildings in Broom Hill
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you have spalled or broken joint edges in floors and decks and sealant peeling off one face of the joint, we can help, on brickwork movement joints, precast concrete panel joints and blockwork control joints alike. Facilities teams, main contractors and managing agents in Broom Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Joints that move: notes for Broom Hill
The 3 miles around Broom Hill take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. 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.
At places like Nugent Retail Park, which lies north-east of Broom Hill, joints are sealed a section at a time so operations carry on. Hospital campuses such as Orpington Hospital, 1.2 miles to the south of Broom Hill, grow in stages, leaving movement joints wherever new blocks meet old. University campuses such as University of Greenwich Avery Hill Campus (to the north of Broom Hill) have car parks, paved walkways and building elevations with movement joints.
Broom Hill is about 1 mile south-west of Orpington, in Greater London. Commercial clients in Broom Hill can call on us for movement joints, as part of our coverage of Greater London.

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 typically costs more in the end than doing them right.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
What the job involves on each 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.
Cladding panel joints
We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.
Questions about Broom Hill
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Is a hospital such as Orpington Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What do you charge?
Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or email drawings and photos with a description of the work.
When can you be on site?
We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
What happens if it rains on the day?
Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Why it’s worth doing now in Broom Hill
Combining joint work with other maintenance reduces set-up costs. But joints already letting water in shouldn’t wait for a programme. Urgent joints now, the rest later, is often the sensible plan. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
