Expansion joint sealing for businesses in West Preston

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

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

How we handle expansion joint sealing in West Preston

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 is tooled so it grips the two faces alone. Most enquiries involve new sealant over old, now failing and movement joints with split or torn sealant, on blockwork control joints, podiums and floor movement joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in West Preston it comes down to the same thing: the right product in a properly prepared joint.

Around West Preston, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. Getting widths, depths and traffic details up front means one visit, not two.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

From enquiry to 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. Several jobs near West Preston can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Flag any permit to work we will need
  • Tell staff and tenants when we’ll be in
  • Have the specification and drawings to hand

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

What the job involves on each surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Car park decks and ramps

Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed.

Looking after the joints

For the best life from the joints:

  • Check joints after long freezing spells
  • Include every elevation and deck joint in periodic inspections
  • Leave barriers in place until fresh joint sealant has cured
  • Note which joints were done, when, and with what

Add every elevation, deck and floor joint to your inspection round. 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, speak to us on 01277 525 020 or email drawings and photos with photographs.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

Questions we are asked in West Preston

Does the sea air around West Preston change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Is a smaller place like West Preston outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you quote for a small job?

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

Are you CHAS accredited?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Does the weather affect joint sealing?

A wet joint can’t be sealed properly so we’d rather rearrange than seal in the rain. The work is simply moved to the next suitable day.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Leaks coming from the membrane rather than the joint seal

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think.

Warehouse floors and decks around West Preston

West Preston lies within about 1 mile of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. West Preston is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

In a school such as Georgian Gardens Community Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Warehouse floors on estates like Rustington Trading Estate (0.7 miles north-west of West Preston) carry pallet trucks and forklifts over every saw-cut joint. Across sites such as The Vinery Industrial Estate, 2 miles to the north of West Preston, floor and movement joints can be sealed in phases so units keep working.
