About our expansion joint sealing in Heyshott

Our movement joint work takes in walls, panels, decks and floors: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. We work on car park decks and ramps, cladding panel joints and podiums and floor movement joints, and the usual reasons a site gets in touch are sealant pulling off the joint face and hardened, cracked sealant on exposed facades. Looking for mastic applicators who cover Heyshott? We have been sealing commercial buildings since 2005.

Halls, schools and small commercial buildings near places like Heyshott have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Building owners, agents and FMs in Heyshott

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Heyshott can form part of a wider programme.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Rural sites near Heyshott may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  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. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

Advice

General trades versus 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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Aftercare for building managers

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

  • Act on the first tear or lifting edge rather than waiting
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Check joints after long freezing spells
  • Avoid parking heavy plant or pallets on joint lines

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, give us a call on 01277 525 020 or use the quote form with photographs.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Sealing early protects the edges.

Leave it or put it right?

Spot repairs can be useful on a tight budget. The remaining sealant is often close to failing too and repeated access costs add up. We can price a patch and a full reseal side by side. Around Heyshott, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why appoint us

  • Coloured sealants to suit the setting, where available
  • Clear, fixed quotes
  • 12-month guarantee on workmanship
  • Public liability insurance in place

Different surfaces, different methods

Joints between different materials

Junctions between brick and render, or concrete and cladding, move independently. We choose a sealant that grips both faces.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement flagging broken arrises before sealing.

FAQs: Heyshott

Do you cover business parks and estates near Heyshott, such as Holmbush Industrial Estate?

Yes, sites like Holmbush Industrial Estate are within our area, along with the rest of Heyshott. A few photos and the unit address let us price the work.

Is Heyshott too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you quote from photos?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Can staff carry on working while you’re here?

Normally, yes. Phased work can be planned so areas stay in use.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote.

Do the joint edges need to be sound before sealing?

Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we’ll say so when we quote.

Slabs, ramps and loading bays in Heyshott

Central London is about 46 miles from Heyshott. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Heyshott is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

For an estate such as Midhurst Community Hospital (2.9 miles north of Heyshott), the joints in ramps, decks and long building elevations all need attention over time. If you manage units on an estate such as Holmbush Industrial Estate, which lies north-west of Heyshott, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. At places like Midhurst Business Centre (2.6 miles north-west of Heyshott), joints are sealed a section at a time so operations carry on.
