Expansion joint sealing across Wisborough Green

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

Our process

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If others near Wisborough Green need work, visits can be combined. You will have a fixed quote before work starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  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. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  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.

Getting the site ready

  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work

How we handle expansion joint sealing in Wisborough Green

Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. We work on car park decks and ramps, precast concrete panel joints and brickwork movement joints, and the failures we’re asked to look at most are leaks through car park deck joints onto the level below and hardened, cracked sealant on exposed facades. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Wisborough Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

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

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Questions we are asked in Wisborough Green

Can you work at a site such as Gillman's Industrial Estate, by Wisborough Green?

Yes. We cover Wisborough Green and the area around it, including industrial estates, business parks and retail parks such as Gillman's Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Will our site in Wisborough Green have to close for joint sealing?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Do the joint edges need to be sound before sealing?

Spalled edges need repairing before a new seal will last and we’ll flag every length affected. A bead on a broken edge soon lets go.

Is Wisborough Green in your area?

Yes. We take on work across Wisborough Green, and the same phone number covers every area.

What happens if it rains on the day?

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

Do you reseal car park expansion joints?

Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we will tell you if any edges need repairing first.

Do you seal on top of existing sealant?

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.

Looking after the joints

To get the most from the new sealant:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Plan racking layouts so feet don’t land on a joint
  • Leave barriers in place until fresh joint sealant has cured
  • Note which joints were done, when, and with what

Snow ploughs and scrapers catch on joint lines. Raising blades over joints where possible protects the seal, and it’s worth checking joints once the cold weather has passed.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

When it isn’t the sealant

Not every problem is a sealant problem, and we’re 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
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If in doubt, call 01277 525 020 or use the quote form and we will say what we think.

What we seal

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

How the job changes by surface

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

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.

Should maintenance staff do it?

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

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.

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, and we will say so before quoting. For buildings around smaller places like Wisborough Green, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
