Expansion joint sealing for commercial buildings in Hawley

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. The enquiries we see most involve car park joints leaking onto vehicles below and joints packed with grit and debris, across car park decks and ramps, blockwork control joints and precast concrete panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Hawley it comes down to the same thing: the right product in a properly prepared joint.

Rural business units around smaller places such as Hawley often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What the job involves on each surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen.

Your questions answered

Is Hawley too small for you to travel to?

No. Places such as Hawley are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Frimley Park Hospital, something you do?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you hold CHAS accreditation?

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

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Do you reseal car park expansion joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement, and phased work can be planned so parts of the car park stay in use.

Cost factors for movement joints

A fixed quote reflects the actual work. It allows for:

  • Whether the work must be split into stages
  • How much existing material needs removing
  • Specialist products, such as fire-rated or hygienic sealants
  • Location, for remote and island sites

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • A wide shot and a close-up of the area
  • The asbestos register, for older buildings
  • Rough lengths or quantities, or drawings if you have them
  • Access details, including height

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, call the office on 01277 525 020 or send details through our quote form.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Leave barriers in place until fresh joint sealant has cured
  • Inspect exposed joints once the cold weather has passed
  • Include every elevation and deck joint in periodic inspections
  • Record the sealant used and the date in the O&M file

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint. Keeping the area coned off until then avoids tyre marks and damage.

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

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. If neighbouring businesses or buildings around Hawley need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  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.

What we need from you

  • Send any specification or drawings in advance
  • Warn occupants and staff about the work
  • Send your site hours and access windows

When to bring in a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

When to call us in Hawley

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens.

Look out for the following:

  • Chipped joint edges on forklift routes
  • Sealant peeling off one face of the joint
  • Expansion joints filled with dirt and stones
  • Water getting into the wall through a failed joint

On a site such as The Meadows Business Park, less than half a mile north of Hawley, the movement joints are in car park slabs, paving and building elevations.

Comparing quotes

  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen
  • Whether primer will be used where the manufacturer specifies it
  • Are they CHAS accredited or on Constructionline?
