How we handle expansion joint sealing in Well End

The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on blockwork control joints, cladding panel joints and brickwork movement joints, and the failures we’re asked to look at most are sealant peeling off one face of the joint and arrises breaking up along floor joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Well End, preparation and product choice get the time they need.

Jobs around smaller places like Well End are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

For managing agents and facilities managers

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Different surfaces, different methods

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement, with primer where specified.

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing and flag any joint that seems undersized.

Why act early in Well End

A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Older rural buildings around Well End 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 and we’ll explain how it’s made up.

Why us?

  • Coloured sealants to suit the setting, where available
  • Work carried out by CSCS-carded applicators
  • 12-month guarantee on workmanship
  • Constructionline member

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Well End, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  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. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Share the asbestos register for older buildings
  • Tell staff and tenants when we will be in
  • Point out any areas we must not close
