Owners, agents and contractors
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Expansion joint sealing in Norwood Green
Long runs of brick or block have movement joints built in. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled with primer where the maker calls for it. Site teams most often ask us about expansion joints filled with dirt and stones and torn sealant in brick or block movement joints, across podiums and floor movement joints, blockwork control joints and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Norwood Green is the same: the right product in a properly prepared joint.
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.
Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Our process
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Planning a London job such as one in Norwood Green starts with access. Give us the hours we can be on site and we’ll schedule to suit.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.
Before we start on site
- Have the specification and drawings to hand
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

How the job changes by surface
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed.
Maintenance after handover
Regular inspection catches problems early. Specifically:
- Avoid parking heavy plant or pallets on joint lines
- Record the sealant used and the date in the O&M file
- Include every elevation and deck joint in periodic inspections
- Check joints after long freezing spells
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.
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. Keeping the filler or sealant sound protects the floor.
What happens if it’s left?
Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too. We can price a patch and a full reseal side by side. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
A quote for movement joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Warehouse floors and decks around Norwood Green
In London, decks, bays and service yards usually have to keep running, so we seal in sections and hand areas back as each cures. Less than 3 miles from Norwood Green there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

For a centre such as Treaty Centre, 1.8 miles south of Norwood Green, the service yard and car park joints normally need attention first.

Questions about Norwood Green
Can you work at a site such as Bridge Road Industrial Estate, by Norwood Green?
Yes, sites like Bridge Road Industrial Estate are within our area, along with the rest of Norwood Green. Send details of the unit and the work through our quote form for a quick quote.
Can you cope with the access rules in a London building?
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. The ULEZ covers the whole of Greater London, which we allow for
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
Can you send site paperwork?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Can the sealant be colour-matched?
It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
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.
