Wincheap: questions and answers

Can you work at a site such as Wincheap Industrial Estate, by Wincheap?

Yes, sites like Wincheap Industrial Estate are within our area, along with the rest of Wincheap. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Can you take on a job at a hospital such as Kent and Canterbury Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you come and look before quoting?

It depends on the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Why do our movement joints keep failing?

The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.

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.

What sealant do you use in movement joints?

It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.

How much does the work cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.

How we handle expansion joint sealing in Wincheap

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. If you have spalled or broken joint edges in floors and decks and sealant peeling off one face of the joint, we can help, on podiums and floor movement joints, blockwork control joints and precast concrete panel joints alike. A specialist sealant contractor works differently from a general builder: in Wincheap, that means joint design, primers and backing rod as standard.

Rural business units around smaller places such as Wincheap often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Leave it or put it right?

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • Clear, fixed quotes
  • Commercial sealant work since 2005
  • Failed material removed, not covered up
  • Health and safety: CHAS accredited

Take a look at our cost guide and our accreditations.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Several jobs near Wincheap can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  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.

Preparing the site

  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work
  • Tell us which areas need to stay in use

How the quote is worked out

We price every job individually. The things that drive the figure:

  • The product specified
  • Whether the work must be split into stages
  • The total length or number of joints
  • Access and working height

Small jobs and large programmes are priced from the same things: 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 a clear picture of the site. Send us:

  • How the joints are reached, and at what height
  • Clear photographs of the problem areas
  • What the building is and how it’s used
  • Asbestos survey details if the building is older

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, ring 01277 525 020 or send photos by email.

Do you need expansion joint sealing in Wincheap?

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.

These are often picked up first by site or facilities staff:

  • Car park joints leaking onto vehicles below
  • Spalled or broken joint edges in floors and decks
  • Hardened, cracked sealant on exposed facades
  • Damp inside where a wall movement joint has failed

For a centre such as Whitefriars Shopping Centre, 0.5 miles north-east of Wincheap, the service yard and car park joints normally need attention first.

What your quote should include

  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Record the sealant used and the date in the O&M file
  • Keep scrapers and ploughs from dragging across joint sealant
  • Treat a small split as a warning, not a cosmetic issue
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Resealing promptly prevents internal damage.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A joint that has to be widened or re-detailed before it can work
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Concrete or masonry repairs along the arrises

If in doubt, ring 01277 525 020 or email us and we will say what we think before you book.
