How we handle expansion joint sealing in Penton Corner

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. If you are dealing with movement joints with split or torn sealant and previous reseals laid over old sealant, we can put it right, whatever the surface. A single leaking joint is often how a building in Penton Corner first comes to us: we look at the rest while we’re there and tell you what we find.

For a site near Penton Corner, measurements and photos up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

The 12-month guarantee covers our workmanship: 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.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Smaller jobs around Penton Corner can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Warn occupants and staff about the work
  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open

Cost factors for movement joints

To price the job, we consider:

  • Backing rod, priming and other preparation
  • How much existing material needs removing
  • Travel to remote or island sites
  • The total length or number of joints

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • What the building is and how it’s used
  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists
  • When you need the work done

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Different surfaces, different methods

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it.

Honest limits

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

  • Movement on a scale no sealant is meant to absorb
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Changing the joint layout or spacing of a structure

If you are not sure, just call 01277 525 020 or email us and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Common questions from Penton Corner clients

Is a hospital such as Andover War Memorial Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Does your area include sites such as Plot 2 Andover Business Park, near Penton Corner?

Yes, sites like Plot 2 Andover Business Park are within our area, along with the rest of Penton Corner. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.

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.

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, including any phasing.

What guarantee do you give on joint sealing?

Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you need to see the site first?

It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.

After the work

Once the work is signed off, a little attention goes a long way:

  • Inspect exposed joints once the cold weather has passed
  • Keep racking legs and heavy point loads off floor joints
  • Clear dirt from joint lines during routine cleaning
  • Reopen bays and walkways only after the stated cure time

Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, call the office on 01277 525 020 or send photos by email with photos.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors by which time the joint has been open for a while. Resealing promptly prevents internal damage.
