Expansion joint sealing near Roundbush Green

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

Expansion joint sealing for commercial buildings in Roundbush Green

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. The enquiries we see most involve expansion joints split through the centre of the bead and water dripping through deck or ramp joints, on cladding panel joints, blockwork control joints and precast concrete panel joints. For commercial sealant work in Roundbush Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For a site near Roundbush Green, measurements and photos up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

On site: what to expect

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Roundbush Green can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints
  • Tell us which areas need to stay in use

What affects the price in Roundbush Green

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • The site’s rules and procedures
  • Which sealant the job calls for
  • Removal of failed or old sealant
  • How accessible the joints are

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

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • Whether the building will be occupied during the work
  • Specification clauses that apply
  • Asbestos survey details if the building is older
  • When you need the work done

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Note which joints were done, when, and with what
  • Look over external and deck joints after a hard winter
  • Brief car park operatives to protect joint lines during winter clearance
  • Put movement joints on the planned maintenance inspection round

Add every elevation, deck and floor joint to your inspection round. 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 call 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. Sealing early protects the edges.

Common problems we fix in Roundbush Green

When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.

Typical triggers for a call:

  • Weathered movement joint sealant that no longer flexes
  • Arrises breaking up along floor joints
  • New sealant over old, now failing
  • Torn sealant in brick or block movement joints

Business parks such as Parklands Business Centre, 1.1 miles south of Roundbush Green, have car parks, paved areas and long brick and panel elevations, all with movement joints.

What to look for in a quote

  • Their public liability cover
  • Which product they’ll use, and why it suits the joint
  • How they handle RAMS and site documents
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

What the job involves on each surface

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.
