Need expansion joint sealing in Golden Pot?

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

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Waterproofing layers buried beneath the sealant
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Movement on a scale no sealant is meant to absorb

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Joints and surfaces we work on

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

Expansion joint sealing for commercial buildings in Golden Pot

The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water. Resealing at the first signs of failure is far cheaper than repairing the material either side. If you are dealing with water getting into the wall through a failed joint and car park joints leaking onto vehicles below, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Golden Pot, that means joint design, primers and backing rod as standard.

For a site near Golden Pot, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

When to call us in Golden Pot

Some joints were never sealed with the right product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.

Most enquiries start with one or more of the following:

  • Layers of sealant in a movement joint
  • Joints packed with grit and debris
  • Joints where the bead has lost adhesion
  • Water getting into the wall through a failed joint

Warehouse floors on estates like Kerridge Industrial Estate, 2.3 miles south-east of Golden Pot, carry pallet trucks and forklifts over every saw-cut joint.

What your quote should include

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How long is the guarantee, and what does it include?
  • Is the sealant right for the movement and the substrate?
  • Health and safety accreditation such as CHAS

Our contractor checklist

Commercial clients in Golden Pot

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Golden Pot. One quote can cover more than one site, so there’s one set of paperwork to deal with.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

How a job runs

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Golden Pot, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  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. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use
  • Tell staff and tenants when we’ll be in

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Advice

How the job changes by surface

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.

Cost factors for movement joints

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • The total length or number of joints

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Anything awkward about access or site hours
  • The product your specification calls for
  • Whether an asbestos survey exists
  • Rough lengths or quantities, or drawings if you have them

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.

Golden Pot: questions and answers

Is Golden Pot off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do you cover business parks and estates near Golden Pot, such as Kerridge Industrial Estate?

Yes. Estates, retail parks and business parks around Golden Pot, Kerridge Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can you work while the building is occupied?

In most cases, yes. Phased work can be planned so areas stay in use.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

What timescale should we allow for resealing expansion joints?

It normally 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. We confirm the timescale with the quote along with the phasing plan.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
