Need expansion joint sealing in The Mint?

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

How we handle expansion joint sealing in The Mint

Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load. If the arrises are already broken, we’ll say so before sealing. Most enquiries involve sealant peeling off one face of the joint and spalled or broken joint edges in floors and decks, across brickwork movement joints, car park decks and ramps and blockwork control joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in The Mint, preparation and product choice get the time they need.

For a site near The Mint, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. A semi-rigid filler is common in trafficked industrial floors.

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. The product must bond to both substrates and cope with the movement, with primer where specified.

Our process

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around The Mint, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First the joints are inspected, widths measured and the type of failure noted.
  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. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Send any specification or drawings in advance
  • Tell us which areas need to stay in use
  • Send asbestos survey details if the building is pre-2000

What we’re called out for in The Mint

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Most enquiries start with one or more of the following:

  • Brittle, chalky sealant on external joints
  • Sealant peeling off one face of the joint
  • Car park joints leaking onto vehicles below
  • Expansion joints split through the centre of the bead

On a site such as Ham Barn Business Park, 1.2 miles to the north-west of The Mint, the movement joints are in car park slabs, paving and building elevations.

What to look for in a quote

  • How they handle RAMS and site documents
  • How long is the guarantee, and what does it include?
  • Proof of insurance
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • How much there is to seal
  • Phasing around occupants
  • Which sealant the job calls for
  • Site requirements such as inductions and permits

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.

Sending details for a quote

Diagnosis starts before we arrive. Tell us:

  • Where the site is, with the postcode
  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • Your programme or deadline

To get a fixed quote, give us a call on 01277 525 020 or email a schedule or drawings. You can also send details through our quote form.

Slabs, ramps and loading bays in The Mint

Less than 3 miles from The Mint there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. The Mint sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

Schools like Liss Junior School often have long brick elevations with movement joints that age quietly. A healthcare site such as Chase Community Hospital (3.9 miles north of The Mint) depends on car parks, ramps and service yards whose joints take traffic all day.

The Mint is about 4 miles north-east of Petersfield, in Hampshire. If you are looking for expansion joint sealing in The Mint, we can help. Across Hampshire, 723 places are covered, The Mint among them. For work in that direction, see our Portsmouth page.

Building owners, agents and FMs in The Mint

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in The Mint can sit alongside others in a wider programme across Hampshire.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Questions we are asked in The Mint

Is The Mint off your patch?

Not at all. The Mint is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Chase Community Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

What timescale should we allow for resealing expansion joints?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so we will tell you if the edges need repairing before sealing. Where it’s visible beforehand, we’ll say so when we quote.

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.

Why has the sealant in our expansion joints split?

Most often the movement is too much for the product or the joint width. We review the joint design as well as the sealant before pricing.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.
