Expansion joint sealing for businesses in Hook

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

Our process

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Hook are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Getting the site ready

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Flag any permit to work we’ll need

Advice

Expansion joint sealing in Hook

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed. We seal and reseal movement joints in walls, panels, decks and floors on sites in Hook. Most enquiries involve spalled or broken joint edges in floors and decks and leaks through car park deck joints onto the level below, across cladding panel joints, blockwork control joints and brickwork movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hook is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Jobs around smaller places like Hook are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses
  • Site requirements such as inductions and permits
  • Working within restricted access windows

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

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it
  • How the joints are reached, and at what height

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

Surface by surface

Cladding panel joints

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

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement, and tell you if edges need repairing first.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Check joints after long freezing spells
  • Inspect movement joints alongside other routine building checks
  • Brief car park operatives to protect joint lines during winter clearance
  • Report split or peeling joint sealant early

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check. Should you spot a problem, you can call the office on 01277 525 020 or email us and send a picture.

A failed deck joint lets water straight through to the level below. That water often carries de-icing salts with it. Sealing the joint promptly stops it at source.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Hook: questions and answers

Would you work within a site like Fareham Community Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Do you cover business parks and estates near Hook, such as Kite's Croft Business Park?

Yes. We cover Hook and the area around it, including industrial estates, business parks and retail parks such as Kite's Croft Business Park. Send details of the unit and the work through our quote form for a quick quote.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Where floor joints take the most wear near Hook

Hook sits close to the coast, within about 1 mile. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. Rainfall across the South East, Hook included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Business parks such as Kite's Croft Business Park (1.5 miles north-east of Hook) have car parks, paved areas and long brick and panel elevations, all with movement joints. Another example is Park Gate Business Centre, 2.2 miles north of Hook, where floors and yards would be done in stages around the occupiers.

Hook is about 1 mile south-east of Warsash, in Hampshire. Businesses, contractors and managing agents in Hook use us for work on movement joints, as part of our coverage of Hampshire. Across Hampshire, 723 places are covered, including Hook. For work in that direction, see our Southampton page (7 miles or so).

Signs you need expansion joint sealing in Hook

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.

Site and facilities staff are often the first to spot these:

  • Hardened, cracked sealant on exposed facades
  • Sealant peeling off one face of the joint
  • Car park joints leaking onto vehicles below
  • Debris jammed in movement joints

Large sites such as Fareham Community Hospital (to the north of Hook) have car parks, service roads and long elevations with movement joints in brick and panels.

What your quote should include

  • Is the sealant right for the movement and the substrate?
  • Proof of insurance
  • What the guarantee covers, and for how long
  • How the joint faces will be prepared and primed
