Expansion joint sealing in Newington Green
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
General trades versus a 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 easy to get wrong without experience.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
About our expansion joint sealing in Newington Green
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. A sealant suited to traffic and the expected movement goes in. If you’re dealing with brittle, chalky sealant on external joints and expansion joints filled with dirt and stones, we can put it right. Looking for mastic applicators who cover Newington Green? We’ve been sealing commercial buildings since 2005.
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.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What happens if it’s left?
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly. We cut out the old seal and prepare the faces every time. Failed sealant in a building in Newington Green can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
A quote for movement joints depends on how many there are, their condition and the access. Call for a quote.

Where floor joints take the most wear near Newington Green
Newington Green 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 normally have to keep running, so the work is broken into short sections agreed with the building manager.
For estates staff at a university like London Metropolitan University, which lies west of Newington Green, building and paving joints are part of the planned maintenance list. On industrial estates such as Frogmore Industrial Estate, 0.5 miles to the west of Newington Green, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. At a retail site such as Arena Shopping Park, 1.8 miles to the north of Newington Green, trolleys, cages and cars run over floor and slab joints all day.
Newington Green is about 1 mile north of Hoxton, in Greater London. Newington Green sits inside our coverage and the rest of Greater London, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Greater London, 764 places are covered, including Newington Green.

What sealant work can’t fix
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Waterproofing layers buried beneath the sealant
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Joints too narrow for the movement, which need redesigning by the engineer

Newington Green: questions and answers
Is hospital work, at somewhere like Moorfields Eye Hospital (City Road campus), something you do?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What timescale should we allow for resealing expansion joints?
The metres of joint, the access and the amount of removal decide it. As a guide, it normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.
How do you choose the sealant?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Our process
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Let building users know which areas are affected
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work

Surface by surface
Brickwork and blockwork joints
Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies.
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Inspect exposed joints once the cold weather has passed
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Keep scrapers and ploughs from dragging across joint sealant
- Record the sealant used and the date in the O&M file
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.
