Expansion joint sealing for businesses in Danaway

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Diagnose, treat, sign off

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Danaway may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  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. Old sealant and debris are cut out of every joint.
  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

  • Point out any areas we must not close
  • Tell us what induction or permit system the site runs
  • Make sure the joints can be reached

How we handle expansion joint sealing in Danaway

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. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. If you have joints where the bead has lost adhesion and joints packed with grit and debris, we can help. For commercial sealant work in Danaway, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Danaway, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Why deal with it now?

Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. Full removal and preparation is in every quote. Older rural buildings around Danaway move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

What you get with us

  • A Constructionline member, so easy to vet
  • Matching to RAL references, product permitting
  • One contact handling all your sites
  • Public liability insurance in place

Read what affects the cost and how we’re accredited.

What sets the cost

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

  • Backing rod, priming and other preparation
  • Any access equipment needed
  • The site’s rules and procedures
  • Whether old sealant has to be cut out first

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • When you need the work done
  • Photos of the joints, close up and from further back
  • The site address and postcode
  • Drawings or a marked-up plan, if available

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email drawings and photos.

When it isn’t the sealant

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

  • Changing the joint layout or spacing of a structure
  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal

If in doubt, speak to us on 01277 525 020 or use the quote form and we’ll say what we think.

Surfaces we seal

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

What we are called out for in Danaway

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

It’s worth sending us details if you spot any of the following:

  • Spalled or broken joint edges in floors and decks
  • Expansion joints split through the centre of the bead
  • Hardened, cracked sealant on exposed facades
  • Sealant peeling off one face of the joint

Phasing is what makes joint work possible on busy sites such as Newington Enterprise Centre (1.5 miles north of Danaway): one bay, aisle or car park row at a time.

What to look for in a quote

  • What the guarantee covers, and for how long
  • Can the work be phased to keep areas open?
  • Their public liability cover
  • How joint depth will be controlled

Our contractor checklist

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Raise snow-clearing blades over deck joints where possible
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Note which joints were done, when, and with what
  • Check joints after long freezing spells

Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records, so the next reseal starts with the facts.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Questions about Danaway

Is Danaway too small for you to travel to?

No. Places such as Danaway are covered as much as the big towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is hospital work, at somewhere like Sittingbourne Memorial Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.

Are you fully insured?

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

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
