About our expansion joint sealing in New Malden
The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you’re dealing with leaks through car park deck joints onto the level below and sealant pulling off the joint face, we can help, on car park decks and ramps, brickwork movement joints and cladding panel joints alike. Whether you call it commercial sealant work, mastic application or joint sealing, in New Malden it comes down to the same thing: the right product in a properly prepared joint.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. When a joint fails, grit and water get in and the arrises start to break up.
Every job we finish is backed by a 12-month workmanship guarantee, in New Malden as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Surface by surface
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
Site staff or a sealant specialist?
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.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

- Whether the work must be split into stages
- The total length or number of joints

Expansion joint sealing in New Malden: the local picture
New Malden has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment. London car parks, loading bays and podium decks often can’t close for long, so we seal in sections and hand areas back as each cures.
Another example is Wyvern Industrial Estate, 0.8 miles to the east of New Malden, where floors and yards would be done in stages around the occupiers. For buildings at a park such as Shannon Commercial Centre, 0.8 miles to the east of New Malden, brick and panel movement joints are easy to forget until one leaks.

Questions we’re asked in New Malden
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Would you work within a site like New Victoria Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What will the job cost?
We don’t publish prices, because every site is different. With photographs or drawings, we can give you a fixed quote.
How long will the joint resealing take?
The metres of joint, the access and the amount of removal decide it. Typically it takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
When to call us in New Malden
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.
Common reasons buildings call us in:
- Expansion joints filled with dirt and stones
- Brittle, chalky sealant on external joints
- New sealant over old, now failing
- Leaks through car park deck joints onto the level below
Campuses like Kingston University, 1.4 miles north-west of New Malden, mix old and new buildings, with movement joints wherever they meet.

From enquiry to sign-off
Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In New Malden, 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.
- We compare each joint’s width with the movement and the sealant’s capability.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Make sure the joints can be reached
- Agree which areas must stay open
- Flag any permit to work we will need
