Expansion joint sealing for businesses in Stonehills

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What happens if it’s left?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Older rural buildings around Stonehills move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Expansion joint sealing in Stonehills

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. The enquiries we see most involve water getting into the wall through a failed joint and expansion joints filled with dirt and stones, across cladding panel joints, brickwork movement joints and car park decks and ramps. Whoever orders the work in Stonehills, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Halls, schools and small commercial buildings near places like Stonehills have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Your questions answered

Is Stonehills too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Coldeast?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Can you work on car park ramps and decks?

Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Is movement joint sealing guaranteed?

Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

What the job involves on each surface

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.

Cladding panel joints

We confirm what access is in place before pricing. Close-up photographs help us judge the joints or a site visit fills the gaps.

Cost factors for movement joints

A fixed quote reflects the actual work. It allows for:

  • Any access equipment needed
  • The total length or number of joints
  • Location, for remote and island sites
  • Site requirements such as inductions and permits

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site rules also count.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • The asbestos register, for older buildings
  • What the building is and how it’s used
  • Anything awkward about access or site hours
  • Clear photographs of the problem areas

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, give us a call on 01277 525 020 or email drawings and photos.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Keep stones and debris out of open joint lines
  • Treat a small split as a warning, not a cosmetic issue
  • Keep traffic off new joints until the cure time is up
  • Inspect movement joints alongside other routine building checks

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.

Slabs, ramps and loading bays in Stonehills

Stonehills sits close to the coast, within about 1 mile. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so it pays to keep them sealed. Stonehills is in the South East, one of the UK’s drier regions. 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.

For buildings at a park such as Ensign Way Business Park (2.4 miles north of Stonehills), brick and panel movement joints are easy to forget until one leaks. Phasing is what makes joint work possible on busy sites such as Glenmore Business Park (2.4 miles north-west of Stonehills): one bay, aisle or car park row at a time. Schools like Fawley Infant School often have long brick elevations with movement joints that age quietly.

General trades versus a specialist

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Stonehills are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  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. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Tell staff and tenants when we’ll be in
  • Let us know about inductions and permits
