Expansion joint sealing for Lamb Corner sites

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

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

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

Expansion joint sealing in Lamb Corner

We’ve been sealing expansion and movement joints for over 20 years. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. If you have damp inside where a wall movement joint has failed and previous reseals laid over old sealant, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Lamb Corner is the same: the right product in a properly prepared joint.

Smaller community and commercial buildings around Lamb Corner have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before we move to the next. If others near Lamb Corner need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  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.

Before we start on site

  • Tell staff and tenants when we will be in
  • Send your site hours and access windows
  • Make sure the joints can be reached

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Joints that move: notes for Lamb Corner

Lamb Corner has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. At about 55 miles from central London, Lamb Corner is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.

Lamb Corner: questions and answers

Is Lamb Corner too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

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

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

What exactly is a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Many people call it an expansion joint and both need a flexible seal.

Which product is best for expansion joints?

Movement capability matters most, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

What if the joint edges are damaged?

Spalled edges need repairing before a new seal will last and we will flag every length affected. Sealing over them leads to early failure.

Does weather matter for sealant work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

When to call us in Lamb Corner

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.

These are often picked up first by site or facilities staff:

  • Joints packed with grit and debris
  • Movement joints with split or torn sealant
  • Joints where the bead has lost adhesion
  • Spalled or broken joint edges in floors and decks

Hospital campuses such as Severalls Hospital, 4 miles to the south-west of Lamb Corner, grow in stages, leaving movement joints wherever new blocks meet old.

How to choose a sealant contractor

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Changing the joint layout or spacing of a structure
  • Crumbling edges that would give a new bead nothing sound to grip

If you are not sure, just call 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Surfaces we seal

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

What sets the cost

The price varies from site to site. Expect it to depend on:

  • Working within restricted access windows
  • Quantities, in metres or numbers
  • Which sealant the job calls for
  • Travel to remote or island sites

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What to include in your enquiry

The more we know, the firmer the quote. Helpful details to send:

  • Access details, including height
  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • Whether an asbestos survey exists

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, phone 01277 525 020 or send details through our quote form.

Maintenance after handover

To get the most from the new sealant:

  • Inspect movement joints alongside other routine building checks
  • Inspect exposed joints once the cold weather has passed
  • Keep scrapers and ploughs from dragging across joint sealant
  • Clear dirt from joint lines during routine cleaning

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check. If anything looks wrong, call the office on 01277 525 020 or email a schedule or drawings with photographs.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Sealing early protects the edges.
