Need expansion joint sealing in South Lambeth?

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

Why deal with it now?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Failed sealant in a building in South Lambeth can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

How we handle expansion joint sealing in South Lambeth

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. We reseal deck and ramp joints with a trafficable sealant chosen for the movement, phasing bays so the car park can stay in use. Most enquiries involve new sealant over old, now failing and car park joints leaking onto vehicles below, across precast concrete panel joints, car park decks and ramps and blockwork control joints. Facilities teams, main contractors and managing agents in South Lambeth tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Areas such as a loading bay or car park deck in South Lambeth typically have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating, at times agreed with the building manager.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Questions about South Lambeth

Would you work within a site like Lambeth Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

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

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

Is it fine to apply new sealant on top of old?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Can staff carry on working while you’re here?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

What we are called out for in South Lambeth

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it.

Most enquiries start with one or more of the following:

  • Car park joints leaking onto vehicles below
  • Torn sealant in brick or block movement joints
  • Rain penetration at brick or block movement joints
  • Hardened, cracked sealant on exposed facades

A healthcare site such as Lambeth Hospital (to the south of South Lambeth) depends on car parks, ramps and service yards whose joints take traffic all day.

Comparing quotes

  • How the joint faces will be prepared and primed
  • Is the sealant right for the movement and the substrate?
  • What the guarantee covers, and for how long
  • Will CSCS-carded applicators be on site?

Surface by surface

Joints between different materials

Different materials meeting at a joint rarely move in step. We choose a sealant that grips both faces.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal.

Honest limits

Honesty saves time and money. New sealant won’t cure:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Movement on a scale no sealant is meant to absorb
  • Waterproofing layers buried beneath the sealant

Not sure which it is? You can phone 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Surfaces we seal

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

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and work section by section so the rest of the building stays in use. For a job in South Lambeth, access comes first: 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 look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Before we start on site

  • Agree which areas must stay open
  • Arrange parking or a loading space
  • Let us know about inductions and permits
