Expansion joint sealing in Englefield

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, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. Site teams most often ask us about hardened, cracked sealant on exposed facades and expansion joints filled with dirt and stones, on precast concrete panel joints, cladding panel joints and podiums and floor movement joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Englefield, that means joint design, primers and backing rod as standard.

In and around smaller places like Englefield, 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 we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Movement on a scale no sealant is meant to absorb
  • Waterproofing layers buried beneath the sealant

If in doubt, phone 01277 525 020 or email the details over and we’ll say what we think.

Where we work in Englefield

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

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. Jobs in and around smaller places like Englefield are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  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. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Share the asbestos register for older buildings
  • Flag any permit to work we’ll need
  • Send your site hours and access windows

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Common questions from Englefield clients

Can you work at a site such as Chiltern Enterprise Centre, by Englefield?

Yes. We cover Englefield and the area around it, including industrial estates, business parks and retail parks such as Chiltern Enterprise Centre. To start, just ring 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.

Would you work within a site like Battle Hospital?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.

Are you fully insured?

Yes. We’re fully insured, including public liability cover.

Do you guarantee expansion joint work?

A 12-month guarantee covers our workmanship and we hold public liability insurance. Keeping joints clear of debris helps them last.

Does the weather affect joint sealing?

The joint has to be dry, and the air and surface temperature inside the product’s limits. Cold, damp or frosty mornings can stop work outside, so we plan with the forecast in mind.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

How the quote is worked out

These are the things that shape the price:

  • Specialist products, such as fire-rated or hygienic sealants
  • Working within restricted access windows
  • Quantities, in metres or numbers
  • Removal of failed or old sealant

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Sending details for a quote

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

  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • Approximate linear metres or a joint schedule

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

What the job involves on each surface

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

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.

Why act early in Englefield

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind, and a second visit means paying for access again. Where it helps, we quote both options. Converted and older buildings near places like Englefield tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Pricing movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Why appoint us

  • A range of standard colours, depending on the product
  • RAL and finish matching where the product range allows
  • Workmanship guaranteed for 12 months
  • Products installed to the manufacturer’s instructions

Common problems we fix in Englefield

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.

Clients typically get in touch after noticing something like this:

  • Expansion joints split through the centre of the bead
  • Water getting into the wall through a failed joint
  • Weathered movement joint sealant that no longer flexes
  • Chipped joint edges on forklift routes

Office parks like Chiltern Enterprise Centre (to the south-east of Englefield) have decks, ramps and clad elevations whose joints take movement every day.

What to look for in a quote
