Expansion joint sealing for commercial buildings in Lower Upham

Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. We seal and reseal movement joints in walls, panels, decks and floors on sites in Lower Upham. We work on podiums and floor movement joints, brickwork movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are rain penetration at brick or block movement joints and new sealant over old, now failing. Most enquiries from Lower Upham start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Smaller community and commercial buildings around Lower Upham have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

The 12-month guarantee is for workmanship rather than 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.

Leave it or put it right?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we’ll plan around it. One visit to deal with every failing joint makes more sense than several trips to a place like Lower Upham, rather than one at a time. Photos of every joint help us quote for the whole job.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal
  • Changing the joint layout or spacing of a structure

Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

Where we work in Lower Upham

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

Doing it in-house

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Lower Upham can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work 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.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

Before we start on site

  • Share your working hours and any access restrictions
  • Tell staff and tenants when we’ll be in
  • Send asbestos survey details if the building is pre-2000

Lower Upham: questions and answers

Can you work at a site such as Deer Park Farm Industrial Estate, by Lower Upham?

Yes. We cover Lower Upham and the area around it, including industrial estates, business parks and retail parks such as Deer Park Farm Industrial Estate. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is Lower Upham too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What happens if it rains on the day?

Weather matters for any external joint because a damp or frozen joint won’t take a proper bond. Internal floor joints are far less affected.

What will the job cost?

Each job is quoted on its own details. To get one, phone 01277 525 020 or send photos by email with a description of the work.

What if the joint edges are damaged?

Broken arrises have to be put right before resealing. A bead on a broken edge soon lets go.

Do you use silicone or polyurethane in movement joints?

The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

For managing agents and facilities managers

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

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 Lower Upham can sit alongside others in a wider programme across Hampshire.

How the quote is worked out

Your fixed quote is built from the real scope. It takes account of:

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

A quote for movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What we need to price the job

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

  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • A wide shot and a close-up of the area
  • Any dates the work must fit around

To get a fixed quote, speak to us on 01277 525 020 or email the details over with the site address and an outline of the work. You can also send details through our quote form.
