Expansion joint sealing in Ham, done properly
Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We’ll tell you if the edges need repairing before sealing, and phased work keeps areas in use. If you have joints packed with grit and debris and sealant pulling off the joint face, we can help. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Ham, that means joint design, primers and backing rod as standard.
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, so it pays to act early.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email us and we will arrange a return visit.

Slabs, ramps and loading bays in Ham
Few London car parks or loading bays can be taken out of use for more than a short spell, which is why we work a few bays at a time. Ham has at least three 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.
Across sites such as Newmans Shipyard & Business Park, 1 mile to the west of Ham, floor and movement joints can be sealed in phases so units keep working. Large sites such as Cassel Hospital (to the south of Ham) have car parks, service roads and long elevations with movement joints in brick and panels.
Ham is about 1 mile south-east of Twickenham, in Greater London. Across the TW10 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Greater London, 764 places are covered, including Ham. Sites around London have their own page, roughly 10 miles from Ham.
Anyone looking for expansion joint sealing in TW10, KT2 and TW11 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your site is on New Road, Lock Road and Cave Road or close by, send details and we’ll quote for movement joints. Access to Ham is via the A307. Nearby places we also cover include Petersham (1 mile north), Eel Pie Island (1 mile north-west), Strawberry Hill (1 mile west), Teddington (1 mile south-west) and Richmond (1 mile north). A short drive away, we cover London (10 miles north-east), City of Westminster (9 miles north-east), Marylebone (9 miles north-east), Kensington (6 miles north-east), St Pancras (10 miles north-east) and Shoreditch (12 miles north-east).

Owners, agents and contractors
CHAS accredited and a Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Your questions answered
Do you take on jobs in Ham where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough
Do you take on work at healthcare sites like Cassel Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Does weather matter for sealant work?
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. Internal work is far less affected.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
What will the job cost?
We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Does the weather affect joint sealing?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside so external dates keep some flexibility.
What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Movement on a scale no sealant is meant to absorb
If in doubt, call 01277 525 020 or email us and we will say what we think.
Joints and surfaces we work on
- Car park decks and ramps
- Blockwork control joints
- Cladding panel joints
- Brickwork movement joints
- Precast concrete panel joints
- Podiums and floor movement joints
Different surfaces, different methods
Car park decks and ramps
Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in.
Podium joints
Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
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.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take.
- Every joint is cleared of the failed seal and any grit packed into it.
- 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.
- 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
- Have the specification and drawings to hand
- Send your site hours and access windows
Getting a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or email a schedule or drawings.

When to call us in Ham
When the movement exceeds the sealant’s capability, the bead tears. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way, so we check width and movement before quoting.
Any of the following is a good reason to get the joints checked over:
- Chipped joint edges on forklift routes
- Movement joints with split or torn sealant
- Joints packed with grit and debris
- New sealant over old, now failing
Warehouse floors on estates like St. George's Industrial Estate (to the south-east of Ham) carry pallet trucks and forklifts over every saw-cut joint.
Questions to ask before you book
- How joint depth will be controlled
- Will CSCS-carded applicators be on site?
- Which product they’ll use, and why it suits the joint
- How they handle RAMS and site documents
