Common questions from Jack's Hatch clients

Do you take on work at healthcare sites like Princess Alexandra Hospital?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does your area include sites such as Latton Bush Business Centre, near Jack's Hatch?

Yes, sites like Latton Bush Business Centre are within our area, along with the rest of Jack's Hatch. Send details of the unit and the work through our quote form for a quick quote.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Does weather matter for sealant work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Is the floor joint work guaranteed?

Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

Is it normal for joint filler to separate?

It can be shrinkage, contamination on the joint faces or a product unsuited to the movement. We look at which it is before recommending anything.

Why act early in Jack's Hatch

Some runs only need partial renewal or topping up. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. One visit to deal with every failing joint makes more sense than several trips to a place like Jack's Hatch. Photos of every joint help us quote for the whole job.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why appoint us

  • Old sealant cut out, never sealed over
  • Workmanship guaranteed for 12 months
  • Health and safety: CHAS accredited
  • Our applicators hold CSCS cards

Honest limits

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

  • Cracks across panels caused by settlement or overload
  • Damaged or worn floor coatings and screeds
  • Level or flatness problems across the floor

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.

Surfaces we seal

  • Retail and showroom floors
  • Forklift and pallet-truck routes
  • Saw-cut induced joints
  • Joints along racking aisles
  • Construction joints
  • Loading bays

Our process

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Jack's Hatch, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We agree the traffic routes and phasing with your site team.
  2. Any joints with broken edges are flagged before work starts.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

Getting the site ready

  • Point out parking and an unloading spot
  • Share the asbestos register for older buildings
  • Send any specification or drawings in advance

What the job involves on each surface

Flexible floor sealants

Flexible floor sealants come in several colours so ask if the colour matters.

Isolation joints at walls and columns

Joints at walls and columns are often missed when floors are sealed, and they collect dust and debris. We include them in the survey.

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

What we are called out for in Jack's Hatch

An ageing filler or sealant can go brittle and split especially under daily scrubbing and traffic. Once it has gone hard or come loose, it protects nothing.

Most enquiries start with something like this:

  • A rough ride across broken joints
  • Chipped and spalling edges along forklift routes
  • Loading bay joints breaking down
  • Flexible sealant torn out by wheels

Parks like Latton Bush Business Centre, 1.6 miles to the north-east of Jack's Hatch, combine paved areas, car parks and building elevations, each with joints that move.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants
  • What level of public liability insurance do they hold?
  • Are they CHAS accredited or on Constructionline?
