Expansion joint sealing for businesses in Great Hormead

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

Why act early in Great Hormead

Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. Around Great Hormead, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What you get with us

  • Fully insured
  • CSCS-carded applicators
  • Workmanship guaranteed for 12 months
  • One phone line for London, the South East and Scotland

About our expansion joint sealing in Great Hormead

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap; water dripping through to the deck below is often the first sign. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you’re dealing with previous reseals laid over old sealant and arrises breaking up along floor joints, we can help, whatever the surface. Facilities teams, main contractors and managing agents in Great Hormead tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Great Hormead, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for movement joints

Your fixed quote is built from the real scope. It takes account of:

  • Travel to remote or island sites
  • Working within restricted access windows
  • The site’s rules and procedures
  • Quantities, in metres or numbers

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Before you send an enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Whether an asbestos survey exists
  • Where the site is, with the postcode
  • Anything awkward about access or site hours
  • The product your specification calls for

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Signs you need expansion joint sealing in Great Hormead

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.

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

  • Damp inside where a wall movement joint has failed
  • Hardened, cracked sealant on exposed facades
  • Car park joints leaking onto vehicles below
  • Spalled or broken joint edges in floors and decks

For a school such as Hormead Church of England (VA) First School, playground and building joints can be done in the holidays.

What your quote should include

  • Health and safety accreditation such as CHAS
  • Their plan for phasing and protecting the area
  • Will RAMS and insurance details be available?
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Expansion joint sealing around Great Hormead: how the place shapes the job

Less than 3 miles from Great Hormead there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

At places like Park Farm Industrial Estate, 2.7 miles west of Great Hormead, joints are sealed a section at a time so operations carry on. Warehouse floors on estates like Watermill Industrial Estate (to the west of Great Hormead) carry pallet trucks and forklifts over every saw-cut joint.

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Great Hormead need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  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. 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. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification
  • Point out any areas we must not close

Maintenance after handover

To get the most from the new sealant:

  • Keep product details with the building records for the next reseal
  • Inspect exposed joints once the cold weather has passed
  • Include every elevation and deck joint in periodic inspections
  • Act on the first tear or lifting edge rather than waiting

Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.

Your questions answered

Will our site in Great Hormead have to close for joint sealing?

Rarely. Work is phased around your operations. We agree the sequence and timings with you before we start.

Does your area include sites such as Watermill Industrial Estate, near Great Hormead?

Yes. Our area takes in Great Hormead and its surroundings, with estates and business parks such as Watermill Industrial Estate included. Photos and a short description are enough for a first look.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Do you take on small jobs?

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

What causes movement joint sealant to fail?

Normally the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

What the job involves on each surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in.
