Expansion joint sealing near Great Chart

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

Owners, agents and contractors

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Expansion joint sealing for commercial buildings in Great Chart

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in. Site teams most often ask us about joints where the bead has lost adhesion and water getting into the wall through a failed joint, across cladding panel joints, precast concrete panel joints and car park decks and ramps. A specialist sealant contractor works differently from a general builder: on jobs in Great Chart, preparation and product choice get the time they need.

Jobs around smaller places like Great Chart are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Leaks coming from the membrane rather than the joint seal
  • Cracking or settlement that calls for an engineer’s assessment

If you are not sure, just speak to us on 01277 525 020 or email us and we’ll give you a straight answer before you book.

Where we work in Great Chart

  • Podiums and floor movement joints
  • Car park decks and ramps
  • Brickwork movement joints
  • Precast concrete panel joints
  • Cladding panel joints
  • Blockwork control joints

Why deal with it now?

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. One visit to deal with every failing joint makes more sense than several trips to a place like Great Chart. Photos of every joint help us quote for the whole job.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Why appoint us

  • Colours confirmed for the specified product
  • Fixed quotes based on photographs, drawings or a visit
  • Coloured sealants to suit the setting, where available
  • One phone line for London, the South East and Scotland

From enquiry to sign-off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a building around Great Chart, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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

  • Arrange parking or a loading space
  • Confirm the product named in the specification
  • Share your working hours and any access restrictions

Surface by surface

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces priming where the maker calls for it.

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • Site requirements such as inductions and permits
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses
  • How much existing material needs removing

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

What to include in your enquiry

However big the job, the same details help:

  • Where the site is, with the postcode
  • Any specification or named product
  • Photos of the joints, close up and from further back
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or send photos by email.

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you cover business parks and estates near Great Chart, such as St. Georges Business Centre?

Yes. We cover Great Chart and the area around it, including industrial estates, business parks and retail parks such as St. Georges Business Centre. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, with one point of contact.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

What causes movement joint sealant to fail?

Typically the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing, rather than replacing like for like.

Floors, slabs and movement joints in Great Chart

Central London is about 47 miles from Great Chart. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day. Rainfall across the South East, Great Chart included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

In a school such as Great Chart Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. At places like Fairwood Industrial Park, 1.1 miles to the east of Great Chart, joints are sealed a section at a time so operations carry on. Hospitals like William Harvey Hospital, 3.5 miles east of Great Chart, have multi-storey or surface car parks whose joints carry vehicles round the clock.
