How we handle expansion joint sealing in Witherenden Hill

Mastic Doctor has sealed movement joints since 2005. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on precast concrete panel joints, car park decks and ramps and blockwork control joints, and what we’re called in for most is joints packed with grit and debris and previous reseals laid over old sealant. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Witherenden Hill is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places such as Witherenden Hill, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

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

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. If others near Witherenden Hill need work, visits can be combined. A fixed quote is given before anything starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

What we need from you

  • Share the asbestos register for older buildings
  • Arrange parking or a loading space
  • Tell us which areas need to stay in use

Advice

Your questions answered

Is Swife Business Park, near Witherenden Hill, within your area?

Yes. Estates, retail parks and business parks around Witherenden Hill, Swife Business Park among them, are all within reach. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Would you work within a site like Ticehurst House Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it.

What guarantee do you give on joint sealing?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

What if the joint edges are damaged?

Spalled edges need repairing before a new seal will last and we’ll flag every length affected. Sealing over them leads to early failure.

Can the building stay open while you work?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

When something else is needed

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Broken or spalled joint edges, which need repairing before any sealant goes in

Not sure which it is? You can phone 01277 525 020 or email us and we will tell you honestly before you book.

Where we work in Witherenden Hill

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

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

When to call us in Witherenden Hill

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.

Any of the following is a good reason to get the joints checked over:

  • Sealant peeling off one face of the joint
  • Chipped joint edges on forklift routes
  • Expansion joints split through the centre of the bead
  • Previous reseals laid over old sealant

For an estate such as Ticehurst House Hospital, 3.4 miles to the north-east of Witherenden Hill, the joints in ramps, decks and long building elevations all need attention over time.

What to look for in a quote

  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?
  • Whether their applicators hold CSCS cards
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

How the quote is worked out

These are the things that shape the price:

  • How accessible the joints are
  • Which sealant the job calls for
  • Whether old sealant has to be cut out first
  • The total length or number of joints

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

What we need to price the job

A few photos plus some basic facts will normally do. It helps to include:

  • The postcode of the building
  • Any specification or named product
  • Any dates the work must fit around
  • Clear photographs of the problem areas

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or email the details over to discuss it first.
