Expansion joint sealing across Richmond

Do you need expansion joint sealing in Richmond?

Three-sided adhesion is a common cause of early failure. Bonded on three faces, it can’t stretch evenly when the joint opens so backing is set before sealing.

Clients typically get in touch after noticing one or more of the following:

  • Water dripping through deck or ramp joints
  • Damp inside where a wall movement joint has failed
  • New sealant over old, now failing
  • Weathered movement joint sealant that no longer flexes

For estates staff at a university like University of London, which lies north-west of Richmond, building and paving joints are part of the planned maintenance list.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • Will RAMS and insurance details be available?
  • How they’ll work around occupants
  • What the guarantee covers, and for how long

Our contractor checklist

Expansion joint sealing in Richmond, done properly

Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. 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 for buildings in Richmond. If you’re dealing with water dripping through deck or ramp joints and sealant pulling off the joint face, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Richmond is the same: the right product in a properly prepared joint.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Richmond means thinking about access, loading times and the ULEZ as well as the joints.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Building owners, agents and FMs in Richmond

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Surface by surface

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement, and confirm it in the quote.

Cladding panel joints

We confirm what access is in place before pricing. Photos taken near the joints help us price accurately.

Joints that move: notes for Richmond

Less than 3 miles from Richmond there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. London car parks, loading bays and podium decks often can’t close for long, so the work is broken into short sections agreed with the building manager.

Another example is Twickenham Trading Estate, which lies west of Richmond, where floors and yards would be done in stages around the occupiers. Retail sites such as Ivybridge Retail Park (to the west of Richmond) have car park, service yard and shop floor joints under constant traffic.

Richmond is about 5 miles south-west of Kensington, in Greater London. If you’re looking for expansion joint sealing in Richmond, we can help, as we do across Greater London. We work across 764 places in Greater London, large and small. For work in that direction, see our London page (9 miles or so).

FAQs: Richmond

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for

Does your area include sites such as Ivybridge Retail Park, near Richmond?

Yes. Estates, retail parks and business parks around Richmond, Ivybridge Retail Park among them, are all within reach. Photos and a short description are enough for a first look.

Why do our movement joints keep failing?

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. Broken edges are a third possibility.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • Removal of failed or old sealant
  • How much there is to seal

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Before you send an enquiry

We can often quote from photographs and a few details. Please tell us:

  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work

Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, give us a call on 01277 525 020 or email a schedule or drawings.

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, 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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. All of Greater London is in the ULEZ, and kerbside space in Richmond can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Flag any permit to work we’ll need
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements
