Expansion joint sealing in Compton

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When to call us in Compton

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.

What tends to prompt an enquiry:

  • Water getting into the wall through a failed joint
  • Joints packed with grit and debris
  • Spalled or broken joint edges in floors and decks
  • Sealant pulling off the joint face

For a school such as Compton C.E. Primary School, playground and building joints can be done in the holidays.

Before you book anyone

  • Their public liability cover
  • Whether their applicators hold CSCS cards
  • Their approach to joint depth and backing
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Expansion joint sealing in Compton, done properly

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels. We will tell you if the edges need repairing before sealing. We work on precast concrete panel joints, cladding panel joints and brickwork movement joints, and what we are called in for most is rain penetration at brick or block movement joints and joints packed with grit and debris. Whether you call it commercial sealant work, mastic application or joint sealing, in Compton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For a site near Compton, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Doing it in-house

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

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.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Compton, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Let building users know which areas are affected
  • Agree which areas must stay open
  • Share the asbestos register for older buildings

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or use the quote form.

Advice

Quoting for work in Compton

These are the things that shape the price:

  • The size and state of each joint
  • Site requirements such as inductions and permits
  • How much existing material needs removing
  • The product specified

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What we need to price the job

A few photos plus some basic facts will normally do. Please tell us:

  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back
  • When you need the work done
  • Drawings or a marked-up plan, if available

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email us to discuss it first.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Cracking or settlement that calls for an engineer’s assessment
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal

Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.

What we seal

  • Podiums and floor movement joints
  • Brickwork movement joints
  • Blockwork control joints
  • Cladding panel joints
  • Car park decks and ramps
  • Precast concrete panel joints

Surface by surface

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement.

Slabs, ramps and loading bays in Compton

Rainfall across the South East, Compton included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in. Compton is about 50 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.

In and around Compton, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Compton: questions and answers

Is Compton too small for you to travel to?

No. Places such as Compton are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do we have to stop operations in Compton while the joints are sealed?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

Can you quote from photographs?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
