Expansion joint sealing for commercial buildings in Collier Row

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. Most enquiries involve previous reseals laid over old sealant and damp inside where a wall movement joint has failed, across car park decks and ramps, podiums and floor movement joints and blockwork control joints. Facilities teams, main contractors and managing agents in Collier Row tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Collier Row means thinking about access, loading times and the ULEZ as well as the joints.

A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, phone 01277 525 020 or email us and we’ll come back to it.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. 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. In Collier Row, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.

A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Concrete or masonry repairs along the arrises
  • Leaks coming from the membrane rather than the joint seal
  • Proprietary pre-formed expansion joint systems

If in doubt, speak to us on 01277 525 020 or use the quote form and we’ll say what we think.

Quoting for work in Collier Row

Your fixed quote is built from the real scope. It takes account of:

  • Whether the work must be split into stages
  • Travel to remote or island sites
  • Any access equipment needed
  • Which sealant the job calls for

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Sending details for a quote

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

  • Your programme or deadline
  • The asbestos register, for older buildings
  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, call the office on 01277 525 020 or email a schedule or drawings.

Signs you need expansion joint sealing in Collier Row

Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks.

Common reasons buildings call us in:

  • Rain penetration at brick or block movement joints
  • Torn sealant in brick or block movement joints
  • Sealant peeling off one face of the joint
  • Expansion joints filled with dirt and stones

Centres like Romford Shopping Hall, 1 mile to the south of Collier Row, have mall floors and service decks whose joints carry steady traffic.

What to look for in a quote

  • Proof of insurance
  • Are they CHAS accredited or on Constructionline?
  • How they handle RAMS and site documents
  • Their approach to joint depth and backing

Questions to ask before you appoint anyone

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  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.

Getting the site ready

  • Move anything stored against the joints
  • Tell staff and tenants when we’ll be in
  • Send any specification or drawings in advance

Ask for a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, give us a call on 01277 525 020 or email a schedule or drawings.

Advice

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Reopen bays and walkways only after the stated cure time
  • Check joints after long freezing spells
  • Treat a small split as a warning, not a cosmetic issue
  • Raise snow-clearing blades over deck joints where possible

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Catching it early keeps the water outside.

Floors, slabs and movement joints in Collier Row

Basement car parks and service yards in London tend to be in use all working day, so we seal in sections and hand areas back as each cures.

Phasing is what makes joint work possible on busy sites such as Business Centre (2.5 miles south of Collier Row): one bay, aisle or car park row at a time. For a school such as Rise Park Infant School, playground and building joints can be done in the holidays.

What causes movement joint sealant to fail?

The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.

Are expansion joints and movement joints the same thing?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably.
