How we handle expansion joint sealing in West Blatchington

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, and the sealant in them keeps water and debris out. We seal and reseal movement joints in walls, panels, decks and floors. If you’re dealing with debris jammed in movement joints and leaks through car park deck joints onto the level below, we can help. One point of contact handles commercial sealant work in West Blatchington from the first photographs to the final walk-round, whether it’s one building or several.

Around West Blatchington, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant
  • Quantities, in metres or numbers
  • Phasing around occupants

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 we will put a fixed figure on it.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Drawings or a marked-up plan, if available
  • The product your specification calls for
  • Your programme or deadline
  • Anything awkward about access or site hours

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or use the quote form.

Your questions answered

Can you take on a job at a hospital such as Mill View Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Does a coastal location like West Blatchington affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can the sealant be colour-matched?

In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What’s the difference between an expansion joint and a movement joint?

The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped, and the sealing method is much the same.

Can you quote from photos?

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

Which product is best for expansion joints?

Movement capability matters most as set out in BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. What matters most for a job in West Blatchington is a clear list of what needs doing, so send photographs of each area. You’ll then get a fixed price for the work.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  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. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Tell staff and tenants when we will be in
  • Agree which areas must stay open
  • Confirm the product named in the specification

Quotes

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, typically low-modulus, with backing rod setting the depth.

When to call us in West Blatchington

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.

Most enquiries start with one or more of the following:

  • Sealant peeling off one face of the joint
  • Torn sealant in brick or block movement joints
  • Leaks through car park deck joints onto the level below
  • Hardened, cracked sealant on exposed facades

University campuses such as University of Brighton Moulesecoomb Campus (2.6 miles east of West Blatchington) have car parks, paved walkways and building elevations with movement joints.

How to choose a sealant contractor

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Include every elevation and deck joint in periodic inspections
  • Note which joints were done, when, and with what
  • Treat a small split as a warning, not a cosmetic issue

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can ring 01277 525 020 or use the quote form and send a picture.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.
