Expansion joint sealing near Hartley Mauditt

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. If others near Hartley Mauditt need work, visits can be combined. A fixed quote is given before anything starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Make sure the joints can be reached
  • Point out any areas we must not close

Expansion joint sealing in Hartley Mauditt

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. If you have torn sealant in brick or block movement joints and chipped joint edges on forklift routes, we can help. One point of contact handles commercial sealant work in Hartley Mauditt from the first photos to the final walk-round, for single jobs and planned programmes alike.

In and around smaller places like Hartley Mauditt, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Why act early in Hartley Mauditt

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now, as damage continues meanwhile. Urgent joints now, the rest later, is often the sensible plan. One visit to deal with every failing joint makes more sense than several trips to a place like Hartley Mauditt, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What you get with us

  • Health and safety: CHAS accredited
  • A range of standard colours, depending on the product
  • Sealing commercial buildings since 2005

Hartley Mauditt: questions and answers

Is Southlands Industrial Park, near Hartley Mauditt, within your area?

Yes, sites like Southlands Industrial Park are within our area, along with the rest of Hartley Mauditt. To start, just speak to us on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Can you work on a hospital site such as Alton Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Are you CHAS accredited?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do you use silicone or polyurethane in movement joints?

Whatever suits the joint and the specification. The quote states the sealant and its movement class so there are no surprises.

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

What sets the cost

These are the things that shape the price:

  • Backing rod, priming and other preparation
  • The total length or number of joints
  • The site’s rules and procedures
  • Location, for remote and island sites

Pricing movement joints depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • Access details, including height
  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • Your programme or deadline

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

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What the job involves on each surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. They take a low-modulus sealant with a movement class to suit laid over backing rod at the correct depth.
