How we handle expansion joint sealing in Dulwich Village

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. If you’re dealing with damp inside where a wall movement joint has failed and arrises breaking up along floor joints, we can put it right, on precast concrete panel joints, blockwork control joints and car park decks and ramps alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Dulwich Village it comes down to the same thing: the right product in a properly prepared joint.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In Dulwich Village, as everywhere in London, access, loading and the ULEZ all come into the plan.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to call us in Dulwich Village

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

Any of the following is a good reason to get the joints checked over:

  • Damp inside where a wall movement joint has failed
  • Expansion joints filled with dirt and stones
  • Expansion joints split through the centre of the bead
  • Joints where the bead has lost adhesion

On industrial estates such as Goose Green Trading Estate (0.9 miles north-east of Dulwich Village), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Choosing a commercial sealant contractor

From enquiry to sign-off

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and we clear our waste as we work. Planning a London job such as one in Dulwich Village starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we’ll schedule to suit.

  1. We assess the joints on site or from photographs, 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. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Share your working hours and any access restrictions
  • Move anything stored against the joints
  • Tell us which areas need to stay in use

Surface by surface

Joints between different materials

Some mixed-material joints suit a hybrid sealant. We pick the product for the materials and the movement, and confirm it in the quote.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen in a colour confirmed for that product.

What happens if it’s left?

Resealing is normally the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. We will flag where edges need repair before sealing. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Keeping the joints sound

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Look over external and deck joints after a hard winter
  • Act on the first tear or lifting edge rather than waiting
  • Clear dirt from joint lines during routine cleaning
  • Avoid parking heavy plant or pallets on joint lines

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, speak to us on 01277 525 020 or use the quote form with photographs.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

Your questions answered

Do you cover business parks and estates near Dulwich Village, such as Goose Green Trading Estate?

Yes. We cover Dulwich Village and the area around it, including industrial estates, business parks and retail parks such as Goose Green Trading Estate. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Can you cope with the access rules in a London building?

Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you work on car park ramps and decks?

Yes. We use a sealant designed for wheel loads and the expected movement.

Does the weather affect joint sealing?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Can one quote cover more than one building?

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