About our expansion joint sealing in Wallend

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you are dealing with torn sealant in brick or block movement joints and spalled or broken joint edges in floors and decks, we can put it right. Facilities teams, main contractors and managing agents in Wallend tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In and around smaller places like Wallend, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. If others near Wallend need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Let us know about inductions and permits
  • Tell us which areas need to stay in use
  • Make sure the joints can be reached

Questions about Wallend

Is Wallend too far out for you?

Not at all. Wallend is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Does the sea air around Wallend change the choice of sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

How long will the joint resealing take?

Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote along with the phasing plan.

What if the joint edges are damaged?

Broken arrises have to be put right before resealing, and we will point out where that’s the case. A bead on a broken edge soon lets go.

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.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can you seal joints in cold or wet weather?

Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Indoor joints can usually carry on regardless.

Warehouse floors and decks around Wallend

Wallend sits close to the coast, within about 1 mile. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. Wallend lies roughly 34 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

For a school such as St James Church of England Primary Academy, playground and building joints can be done in the holidays.

Wallend is about 5 miles north-west of Minster, in Medway. We send applicators to Wallend for movement joints. Wallend is one of 54 places we cover in Medway for movement joints. Our London page has more on work in that area (34 miles or so).

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Some joints are best left to specialists: for instance 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.

What sealant work can’t fix

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Changing the joint layout or spacing of a structure
  • Leaks coming from the membrane rather than the joint seal
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

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

Joints and surfaces we work on

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

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Raise snow-clearing blades over deck joints where possible
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Keep racking legs and heavy point loads off floor joints
  • Inspect movement joints alongside other routine building checks

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.

What affects the price in Wallend

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

  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are
  • Induction, permit and paperwork requirements

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work
  • Anything awkward about access or site hours
  • Your programme or deadline

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Signs you need expansion joint sealing in Wallend

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. The product has to be suited to the traffic.

If one of these sounds familiar, it’s time for a closer look:

  • Hardened, cracked sealant on exposed facades
  • Damp inside where a wall movement joint has failed
  • Expansion joints split through the centre of the bead
  • Sealant peeling off one face of the joint

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