Expansion joint sealing for businesses in Windlesham

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

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Several jobs near Windlesham can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  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. 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.

Preparing the site

  • Explain the parking and delivery arrangements
  • Move anything stored against the joints
  • Tell staff and tenants when we’ll be in

About our expansion joint sealing in Windlesham

Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Movement joints are where that movement is absorbed. We seal and reseal movement joints in walls, panels, decks and floors. We work on podiums and floor movement joints, brickwork movement joints and car park decks and ramps, and what we’re called in for most is torn sealant in brick or block movement joints and sealant peeling off one face of the joint. A single leaking joint is often how a building in Windlesham first comes to us: we look at the rest while we are there and tell you what we find.

Around Windlesham, most floor and movement joint jobs are single buildings or yards. Getting widths, depths and traffic details up front means one visit, not two.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Proprietary pre-formed expansion joint systems
  • Waterproofing layers buried beneath the sealant

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.

Where we work in Windlesham

  • Brickwork movement joints
  • Blockwork control joints

Signs you need expansion joint sealing in Windlesham

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

If one of these sounds familiar, it’s time for a closer look:

  • Weathered movement joint sealant that no longer flexes
  • Water dripping through deck or ramp joints
  • Expansion joints filled with dirt and stones
  • Torn sealant in brick or block movement joints

For an estate such as Heatherwood Hospital, which lies north-west of Windlesham, the joints in ramps, decks and long building elevations all need attention over time.

How to choose a sealant contractor

Slabs, ramps and loading bays in Windlesham

At about 26 miles from central London, Windlesham is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds. Rainfall across the South East, Windlesham included, is lower than in many 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.

A campus such as Imperial College Silwood Park Campus, 3.1 miles to the north of Windlesham, has long runs of movement joint in its buildings, decks and paving. Parks like Ascot Business Park, 2.8 miles north of Windlesham, combine paved areas, car parks and building elevations, each with joints that move.

Windlesham is about 4 miles north-east of Camberley, in Surrey. We cover Windlesham and the rest of Surrey, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Surrey, 379 places are covered, including Windlesham. Reading is covered too, some 15 miles away.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Keeping the joints sound

After handover, these steps help:

  • Leave barriers in place until fresh joint sealant has cured
  • Avoid parking heavy plant or pallets on joint lines
  • Report split or peeling joint sealant early
  • Raise snow-clearing blades over deck joints where possible

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints, and report any chipped edges early.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers. Sealing early protects the edges.

Your questions answered

Will you take on work at estates like Ascot Business Park, close to Windlesham?

Yes. We cover Windlesham and the area around it, including industrial estates, business parks and retail parks such as Ascot Business Park. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Windlesham outside your area?

Not at all. Windlesham is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work on car park ramps and decks?

Yes. These joints take wheels, salt and water, so product choice matters and broken edges are flagged before sealing.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Why has the sealant in our expansion joints split?

Normally the joint is moving more than the sealant can take. We review the joint design as well as the sealant before pricing.

Work for main contractors and building owners

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
