How a job runs
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. In Custom House, 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.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Preparing the site
- Point out any areas we must not close
- Let building users know which areas are affected
- Flag any permit to work we will need

Expansion joint sealing for commercial buildings in Custom House
Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we’ll say so before sealing, and phased work keeps areas in use. Site teams most often ask us about water getting into the wall through a failed joint and torn sealant in brick or block movement joints, across brickwork movement joints, car park decks and ramps and podiums and floor movement joints. Facilities teams, main contractors and managing agents in Custom House tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Slabs, ramps and loading bays in Custom House
Few London car parks or loading bays can be taken out of use for more than a short spell, so joints are sealed in sections with each area handed back once cured. The 3 miles around Custom House take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
A campus such as Ravensbourne University London (to the west of Custom House) has long runs of movement joint in its buildings, decks and paving. Warehouse floors on estates like Greenshields Industrial Estate, 0.5 miles south-west of Custom House, carry pallet trucks and forklifts over every saw-cut joint.
Custom House is about 1 mile south of Canning Town, in Greater London. Anywhere in E16, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Across Greater London, 764 places are covered, including Custom House.
Work on movement joints is covered throughout E16 and E13. For a building on Tree Road, Ethel Road and Booth Road or nearby, send details and we’ll quote for movement joints. Custom House sits on or close to the A1020, which helps when planning parking and deliveries for the job. Nearby places we also cover include West Silvertown (1 mile south-west), Silvertown (1 mile south), Canning Town (1 mile north), Royal Docks (1 mile east) and Limmo Peninsula (1 mile west) for movement joints. Nearby towns on our patch include London (5 miles west), City of Westminster (8 miles west), Marylebone (8 miles west), Kensington (10 miles west), St Pancras (6 miles west) and Shoreditch (5 miles west).
Landmarks near Custom House
Around Custom House, our work takes us to commercial buildings near Thames Barrier Park, The Royal Docks Community School and Royal Docks Academy, among other places. There’s a railway station in Custom House itself: Custom House station. Other landmarks nearby include Gallions Reach Shopping Park (2.2 miles east) and Charlton Athletic Museum (1.5 miles south). Not far away are Gilbert's Pit and Tower Hill.
Why act early in Custom House
Doing joint resealing alongside other planned works can save on access. But joints already letting water in shouldn’t wait for a programme, as damage continues meanwhile. We can split the scope into urgent and planned. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Brief car park operatives to protect joint lines during winter clearance
- Inspect exposed joints once the cold weather has passed
- Record the sealant used and the date in the O&M file
- Inspect movement joints alongside other routine building checks
In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.
Building owners, agents and FMs in Custom House
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Custom House. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
When to call us in Custom House
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Look out for the following:
- Water dripping through deck or ramp joints
- Rain penetration at brick or block movement joints
- Chipped joint edges on forklift routes
- Layers of sealant in a movement joint
Centres like Brocklebank Retail Park (1.2 miles south of Custom House) have mall floors and service decks whose joints carry steady traffic.
Questions to ask before you book
- Can the work be phased to keep areas open?
- Are they CHAS accredited or on Constructionline?
- Whether old or failed sealant will be cut out, not overlaid
- Their public liability cover
Custom House: questions and answers
Is hospital work, at somewhere like Newham University Hospital, something you do?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you cover business parks and estates near Custom House, such as Greenshields Industrial Estate?
Yes. Estates, retail parks and business parks around Custom House, Greenshields Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Can a joint be sealed if the edges are broken?
Sound edges are essential. If they’re damaged, we’ll say so before any sealing.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can you work on car park ramps and decks?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.
Can weather delay the job?
It can, for external work. 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. Indoors, the weather is rarely a problem.
What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Waterproofing layers buried beneath the sealant
- A joint that has to be widened or re-detailed before it can work
- Cracking or settlement that calls for an engineer’s assessment
If you’re not sure, just call the office on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
