Expansion joint sealing in Sidlow: the local picture

At least three named trading, business or retail sites lie within about 3 miles of Sidlow. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Sidlow is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, while winter salting gets into any joint left open.

Across sites such as Salbrook Road Industrial Estate, 1.7 miles to the east of Sidlow, floor and movement joints can be sealed in phases so units keep working. Large sites such as East Surrey Hospital, 1.9 miles to the north-east of Sidlow, have car parks, service roads and long elevations with movement joints in brick and panels.

Sidlow is about 2 miles south of Reigate, in Surrey. Across the RH2 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Sidlow is one of 379 places we cover in Surrey. Our London page has more on work in that area (21 miles or so).

Work on movement joints is covered throughout RH2, whatever the building. If your building is just outside Sidlow, we cover Irons Bottom (1 mile south-west), South Park (1 mile north), Leigh (2 miles west), Reigate (2 miles north) and Dawesgreen (2 miles west). Nearby towns on our patch include Epsom (9 miles north), Redhill (3 miles north-east), Ewell (10 miles north), Walton-on-Thames (15 miles north-west), Caterham (7 miles north-east) and Dorking (6 miles west).

Expansion joint sealing for commercial buildings in Sidlow

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you are dealing with hardened, cracked sealant on exposed facades and damp inside where a wall movement joint has failed, we can put it right, on cladding panel joints, blockwork control joints and car park decks and ramps alike. For commercial sealant work in Sidlow, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Sidlow, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

When to call us in Sidlow

When a bead pulls away from one face, it has lost adhesion. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.

Typical triggers for a call:

  • Joints where the bead has lost adhesion
  • Damp inside where a wall movement joint has failed
  • Spalled or broken joint edges in floors and decks
  • Water dripping through deck or ramp joints

In a school such as Dovers Green School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • What site paperwork they can supply
  • How joint depth will be controlled
  • Their public liability cover

Choosing a commercial sealant contractor

Work for main contractors and building owners

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

We work for building owners and managing agents on everything from one building to a spread of sites around Sidlow. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Why deal with it now?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open. We agree phasing with you before work starts. Halls, stores and units around places like Sidlow may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why appoint us

  • Fully insured
  • 12 months’ guarantee on every job
  • Colours chosen to suit frames, cladding or finishes where possible
  • Joints cleaned back to sound surfaces

Read our cost guide or how we’re accredited.

What affects the price in Sidlow

The price varies from site to site. It mainly depends on:

  • Working within restricted access windows
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements
  • How much there is to seal

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Sending details for a quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Any dates the work must fit around
  • Specification clauses that apply
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, speak to us on 01277 525 020 or email the details over.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a building around Sidlow, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Point out any areas we must not close
  • Share your working hours and any access restrictions
  • Clear stock, furniture or equipment away from the joints

Advice

Surface by surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. The sealant needs the right movement capability and a controlled depth.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen, and we will confirm the colours available for the specified product.

Questions we’re asked in Sidlow

Can you work at a site such as Fontigarry Farm Business Park, by Sidlow?

Yes. Estates, retail parks and business parks around Sidlow, Fontigarry Farm Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Would you work within a site like East Surrey Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Are you fully insured?

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

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Can the building stay open while you work?

Normally, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

Is colour matching possible?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

What causes movement joint sealant to fail?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.
