Expansion joint sealing in Old Chiswick
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors on sites in Old Chiswick. We work on podiums and floor movement joints, blockwork control joints and car park decks and ramps, and the usual reasons a site gets in touch are previous reseals laid over old sealant and expansion joints split through the centre of the bead. Looking for mastic applicators who cover Old Chiswick? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Most London buildings can’t shut a car park, loading bay or warehouse floor for long. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Why act early in Old Chiswick
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we’ll tell you they need repairing first. In Old Chiswick, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Should maintenance staff do it?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

What else we do in Old Chiswick
After the work
For the best life from the joints:
- Include every elevation and deck joint in periodic inspections
- Act on the first tear or lifting edge rather than waiting
- Raise snow-clearing blades over deck joints where possible
- Leave barriers in place until fresh joint sealant has cured
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines, and report any chipped edges early.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort. We can suggest an order, worst joints first.
What affects the price in Old Chiswick
We price every job individually. The main factors are:
- Which sealant the job calls for
- Access and working height
- The size and state of each joint
- Phasing around occupants
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Clear photos of the problem areas
- Any specification or named product
- The asbestos register, for older buildings
- Anything awkward about access or site hours
Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or email drawings and photos.
Slabs, ramps and loading bays in Old Chiswick
In London, decks, bays and service yards typically have to keep running, so the work is broken into short sections agreed with the building manager. Less than 3 miles from Old Chiswick there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
For a store at a site such as Kew Retail Park (1.4 miles south-west of Old Chiswick), the service yard and goods-in area are where joints break down first. Across sites such as Berghem Mews Business Village, which lies north-east of Old Chiswick, floor and movement joints can be sealed in phases so units keep working. Schools like The William Hogarth Primary School often have long brick elevations with movement joints that age quietly.

Old Chiswick: questions and answers
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
Does your area include sites such as Kew Retail Park, near Old Chiswick?
Yes. Our area takes in Old Chiswick and its surroundings, with estates and business parks such as Kew Retail Park included. To start, just ring 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Why has the sealant in our expansion joints split?
It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
How long will the joint resealing take?
Expect a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases and phased work can stretch that to suit your site. We will confirm when each area can be used again.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Building owners, agents and FMs in Old Chiswick
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Our process
Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. All of Greater London is in the ULEZ, and kerbside space in Old Chiswick can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
