Expansion joint sealing for commercial buildings in Hextable

We’ve been sealing expansion and movement joints for over 20 years. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on podiums and floor movement joints, precast concrete panel joints and brickwork movement joints, and the failures we are asked to look at most are layers of sealant in a movement joint and movement joints with split or torn sealant. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hextable is the same: the right product in a properly prepared joint.

Around places the size of Hextable, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Concrete floors and yards in these buildings move and crack like any others.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • The site’s rules and procedures
  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • Which sealant the job calls for

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • The type of building and who uses it
  • Asbestos survey details if the building is older
  • The postcode of the building
  • Clear photos of the problem areas

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, speak to us on 01277 525 020 or send details through our quote form.

What happens if it’s left?

Doing joint resealing alongside other planned works can save on access. Leaking joints need sealing now because damage continues. We can split the scope into urgent and planned. Small buildings around Hextable suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Why appoint us

  • Colours confirmed for the specified product
  • A range of standard colours, depending on the product
  • Fixed quotes based on photos, drawings or a visit
  • RAL and finish matching where the product range allows

Common problems we fix in Hextable

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.

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

  • Arrises breaking up along floor joints
  • Brittle, chalky sealant on external joints
  • Debris jammed in movement joints
  • Joints where the bead has lost adhesion

Business parks such as Pembroke Business Centre, 0.7 miles to the south-west of Hextable, have car parks, paved areas and long brick and panel elevations, all with movement joints.

What your quote should include

  • Is the sealant right for the movement and the substrate?
  • Who will actually carry out the work
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance

Our contractor checklist

On site: what to expect

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Several jobs near Hextable can be grouped on one trip. Tell us your site hours and we’ll plan around them.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Flag any permit to work we’ll need
  • Send any specification or drawings in advance
  • Move anything stored against the joints

Your questions answered

Is Hextable off your patch?

Not at all. Hextable is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Pembroke Business Centre, near Hextable?

Yes. We cover Hextable and the area around it, including industrial estates, business parks and retail parks such as Pembroke Business Centre. A few photos and the unit address let us price the work.

What will the job cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Do you have public liability insurance?

Yes. We are fully insured, including public liability cover.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Report split or peeling joint sealant early
  • Check joints after long freezing spells
  • Keep traffic off new joints until the cure time is up
  • Put movement joints on the planned maintenance inspection round

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in and long before edges start to break. Should you spot a problem, you can speak to us on 01277 525 020 or send photos by email and send a picture.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster. Sealing early protects the edges.
