Expansion joint sealing across Mill Street

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

About our expansion joint sealing in Mill Street

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. If you’re dealing with chipped joint edges on forklift routes and damp inside where a wall movement joint has failed, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Mill Street, that means joint design, primers and backing rod as standard.

For a site near Mill Street, measurements and photographs 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.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we will come back to it.

Building owners, agents and FMs in Mill Street

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

What affects the price in Mill Street

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

  • How much existing material needs removing
  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

We can often quote from photos and a few details. It helps to include:

  • The postcode of the building
  • How the joints are reached, and at what height
  • When you need the work done
  • A wide shot and a close-up of the area

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can call 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

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

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Mill Street, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We look at the joints, their width and how they’ve failed.
  2. A fixed quote follows, naming the sealant and its movement class.
  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. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Confirm the product named in the specification
  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints

When to call us in Mill Street

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch.

Clients usually get in touch after noticing one or more of the following:

  • Sealant pulling off the joint face
  • Joints packed with grit and debris
  • Torn sealant in brick or block movement joints
  • Water getting into the wall through a failed joint

Hospitals like Severalls Hospital, 5.7 miles to the south of Mill Street, have multi-storey or surface car parks whose joints carry vehicles round the clock.

What your quote should include

  • Their approach to joint depth and backing
  • Do they follow the manufacturer’s priming guidance?
  • Their public liability cover
  • The named product and why it was chosen

Choosing a commercial sealant contractor

Mill Street: questions and answers

Will our site in Mill Street have to close for joint sealing?

In the majority of 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.

Can you work on a hospital site such as Severalls Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What happens if it rains on the day?

Outside work depends on conditions because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.

What causes movement joint sealant to fail?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Where floor joints take the most wear near Mill Street

The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open. Mill Street is about 55 miles from central London. Warehousing clusters around the motorways that ring and radiate from London.

For a school such as Stoke-by-Nayland Church of England Primary School, playground and building joints can be done in the holidays.

Surface by surface

Joints between different materials

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

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond, so the new seal holds.
