How we handle expansion joint sealing in Lockerley

For movement joints in Lockerley, photos and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed, then send a fixed quote that names the sealant. You can also call 01277 525 020 or send details through our quote form to talk the joints through. If you have previous reseals laid over old sealant and water dripping through deck or ramp joints, we can put it right, whatever the surface. A single leaking joint is often how a building in Lockerley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Jobs around smaller places like Lockerley are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Lockerley, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  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. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Questions we are asked in Lockerley

Can you work on a hospital site such as Romsey Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Lockerley too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Can the building stay open while you work?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • Put movement joints on the planned maintenance inspection round
  • Keep stones and debris out of open joint lines
  • Report split or peeling joint sealant early
  • Record the sealant used and the date in the O&M file

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Catching it early keeps the water outside.

How the job changes by surface

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies, then seal and tool the joint.

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 and check the edges for soundness as we go.

Cost factors for movement joints

We price every job individually. The main factors are:

  • Backing rod, priming and other preparation
  • How accessible the joints are
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

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

  • Whether the building will be occupied during the work
  • Rough lengths or quantities, or drawings if you have them
  • Where the site is, with the postcode
  • Your programme or deadline

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Why deal with it now?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed. Older rural buildings around Lockerley move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

Why appoint us

  • Health and safety: CHAS accredited
  • Fully insured, including public liability cover
  • A Constructionline member, so easy to vet
  • Matching to RAL references, product permitting

Joints that move: notes for Lockerley

Rainfall across the South East, Lockerley included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

For an estate such as Romsey Community Hospital (4.9 miles south-east of Lockerley), the joints in ramps, decks and long building elevations all need attention over time. For a school such as Lockerley Church of England Endowed Primary School, playground and building joints can be done in the holidays.

Do you need expansion joint sealing in Lockerley?

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

Look out for the following:

  • Water dripping through deck or ramp joints
  • Previous reseals laid over old sealant
  • Arrises breaking up along floor joints
  • Sealant pulling off the joint face

On a site such as Home Farm Business Centre, 1.3 miles to the north of Lockerley, the movement joints are in car park slabs, paving and building elevations.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?
