Expansion joint sealing in Single Street
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. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on brickwork movement joints, cladding panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are sealant peeling off one face of the joint and rain penetration at brick or block movement joints. Most enquiries from Single Street start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Single Street, 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, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Planning a London job such as one in Single Street starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Point out any areas we must not close
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed

Building owners, agents and FMs in Single Street
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Single Street can sit alongside others in a wider programme.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Keeping the joints sound
For the best life from the joints:
- Reopen bays and walkways only after the stated cure time
- Include every elevation and deck joint in periodic inspections
- Treat a small split as a warning, not a cosmetic issue
- Keep stones and debris out of open joint lines
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. If anything looks wrong, phone 01277 525 020 or email the details over with photographs.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We’ll tell you which movement joints need doing now and which can wait.
Floors, slabs and movement joints in Single Street
Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures. Single Street has two named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.
If you manage units on an estate such as Biggin Hill Airport Trading Estate, 1.3 miles west of Single Street, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. In a school such as Cudham Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Across sites such as Glebe Farm Business Park, 2.4 miles north-west of Single Street, floor and movement joints can be sealed in phases so units keep working.

Single Street: questions and answers
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. All of Greater London is inside the ULEZ, and our planning allows for it
Does your area include sites such as Biggin Hill Airport Trading Estate, near Single Street?
Yes. Our area takes in Single Street and its surroundings, with estates and business parks such as Biggin Hill Airport Trading Estate included. A few photographs and the unit address let us price the work.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
Will you come and look before quoting?
Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
How the job changes by surface
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement, phased so parts of the car park stay open.
How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- The total length or number of joints
- How much existing material needs removing
- Backing rod, priming and other preparation
- Working within restricted access windows
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Send us:
- A wide shot and a close-up of the area
- Any specification or named product
- Any dates the work must fit around
- How the joints are reached, and at what height
A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email the details over to discuss it first.
Should maintenance staff do it?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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 usually costs more in the end than doing them right.
