About our expansion joint sealing in Aldershot

We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we’ll confirm the choice in the quote. Most enquiries involve expansion joints filled with dirt and stones and joints where the bead has lost adhesion, on brickwork movement joints, cladding panel joints and car park decks and ramps. A specialist sealant contractor works differently from a general builder: in Aldershot, that means joint design, primers and backing rod as standard.

In Aldershot, as in most towns, brickwork and panel movement joints on public and commercial buildings age quietly. A split or hardened joint lets rain into the wall, and it can no longer take up the movement.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Aldershot: questions and answers

Does a site in Aldershot have to shut while its joints are sealed?

Normally not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Is Westgate Shopping Centre, near Aldershot, within your area?

Yes. Estates, retail parks and business parks around Aldershot, Westgate Shopping Centre among them, are all within reach. A few photographs and the unit address let us price the work.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

Is movement joint sealing guaranteed?

The workmanship is guaranteed for 12 months from sign-off, and we are fully insured for public liability. Keeping joints clear of debris helps them last.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

What do you charge?

We don’t publish prices, as every site differs. Send photos or drawings and we’ll price it at a fixed figure.

Do the joint edges need to be sound before sealing?

Spalled edges need repairing before a new seal will last. Sealing over them leads to early failure.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. If you have more than one building in Aldershot, they can often be done on the same visit. Tell us when the building is open and we’ll plan to suit.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  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. The failed seal is cut out and both joint faces cleaned back to sound material.
  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.

Preparing the site

  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close

Expansion joint sealing around Aldershot: how the place shapes the job

At least three named trading, business or retail sites lie within about 3 miles of Aldershot. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in.

Schools like Talavera Junior School often have long brick elevations with movement joints that age quietly. Another example is Preymead Industrial Estate (0.9 miles south of Aldershot), where floors and yards would be done in stages around the occupiers. Hospital campuses such as Farnham Community Hospital (2.1 miles south-west of Aldershot) grow in stages, leaving movement joints wherever new blocks meet old.

Doing it in-house

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 where general trades tend to cut corners.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Maintenance after handover

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

  • Keep product details with the building records for the next reseal
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Look over external and deck joints after a hard winter
  • Reopen bays and walkways only after the stated cure time

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. A sound seal keeps the joint working.

Commercial clients in Aldershot

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

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 Aldershot can sit alongside others in a wider programme.

When it isn’t the sealant

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Movement on a scale no sealant is meant to absorb
  • Crumbling edges that would give a new bead nothing sound to grip
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Surfaces we seal

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

What affects the price in Aldershot

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation
  • Removal of failed or old sealant
  • Quantities, in metres or numbers

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
