Expansion joint sealing in Hayes

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Expansion joint sealing in Hayes

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, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. We work on cladding panel joints, brickwork movement joints and podiums and floor movement joints, and the usual reasons a site gets in touch are arrises breaking up along floor joints and leaks through car park deck joints onto the level below. Most enquiries from Hayes start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Around Hayes, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. When a joint fails, grit and water get in and the arrises start to break up.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. All of Greater London is in the ULEZ, and kerbside space in Hayes can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Let building users know which areas are affected
  • Send any specification or drawings in advance

Related advice

Hayes: questions and answers

Is Chartwell Business Centre, near Hayes, within your area?

Yes. We cover Hayes and the area around it, including industrial estates, business parks and retail parks such as Chartwell Business Centre. A few photographs and the unit address let us price the work.

Do you take on jobs in Hayes where loading and access are tightly controlled?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we’ll work to them.

How do we ask for a quote?

You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send photos by email. Include photographs or drawings if you have them.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Can you handle several sites?

Yes. Several buildings can share a single quote, with one point of contact.

Do you reseal car park expansion joints?

Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we will tell you if any edges need repairing first.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Surface by surface

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.

What sets the cost

These are the things that shape the price:

  • Whether the work must be split into stages
  • Quantities, in metres or numbers
  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Details that help us quote

To price the job accurately, we need to understand the site. Send us:

  • Drawings or a marked-up plan, if available
  • The postcode of the building
  • Any dates the work must fit around
  • Whether the building will be occupied during the work

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Do you need expansion joint sealing in Hayes?

Some joints were never sealed with the right product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.

Common reasons buildings call us in:

  • Rain penetration at brick or block movement joints
  • Weathered movement joint sealant that no longer flexes
  • Torn sealant in brick or block movement joints
  • Sealant peeling off one face of the joint

Hospitals like Bethlem Royal Hospital (1.6 miles west of Hayes) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Questions to ask before you book

  • Their approach to joint depth and backing
  • What the guarantee covers, and for how long
  • Will RAMS and insurance details be available?
  • Will CSCS-carded applicators be on site?

Choosing a commercial sealant contractor

What happens if it’s left?

Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too and repeated access costs add up. 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.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Fixed quotes based on photos, drawings or a visit
  • CHAS accredited
  • Old sealant cut out, never sealed over
  • Work to your specification and the manufacturer’s guidance

Warehouse floors and decks around Hayes

At least three named trading, business or retail sites lie within about 3 miles of Hayes. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. 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.

Centres like The Mall, 1.9 miles to the north of Hayes, have mall floors and service decks whose joints carry steady traffic. Another example is Glebe Farm Business Park, 2.3 miles south-east of Hayes, where floors and yards would be done in stages around the occupiers.
