Expansion joint sealing across Fernhurst

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in Fernhurst, done properly

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve damp inside where a wall movement joint has failed and sealant peeling off one face of the joint, across car park decks and ramps, podiums and floor movement joints and precast concrete panel joints. One point of contact handles commercial sealant work in Fernhurst from the first photos to the final walk-round, whether it’s one building or several.

Around smaller places such as Fernhurst, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

What sets the cost

We price every job individually. The things that drive the figure:

  • Which sealant the job calls for
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Travel to remote or island sites

What a job costs comes down to the quantity of joints, what has to come out first and how the joints are reached. Call for a quote once you have the details.

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Your programme or deadline
  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • Where the site is, with the postcode

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, give us a call on 01277 525 020 or send details through our quote form.

FAQs: Fernhurst

Is Fernhurst off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Do you cover business parks and estates near Fernhurst, such as Hurstfold Industrial Estate?

Yes, sites like Hurstfold Industrial Estate are within our area, along with the rest of Fernhurst. Photos and a short description are enough for a first look.

Are you fully insured?

Yes. We’re fully insured, and the certificate can go with your quote.

What do you charge?

We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.

Are expansion joints and movement joints the same thing?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.

Will you come and look before quoting?

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

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:

  • Crumbling edges that would give a new bead nothing sound to grip
  • Movement on a scale no sealant is meant to absorb
  • Changing the joint layout or spacing of a structure

If in doubt, ring 01277 525 020 or email drawings and photos and we will say what we think.

Surfaces we seal

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

Traffic, movement and joints around Fernhurst

The 3 miles around Fernhurst take in at least three named trading estates, business parks or retail parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Fernhurst is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

Phasing is what makes joint work possible on busy sites such as Kings Road Industrial Estate (2.5 miles north of Fernhurst): one bay, aisle or car park row at a time. Schools such as Fernhurst Primary School have movement joints in their walls and floors that are easy to overlook.

Fernhurst is about 10 miles east of Petersfield, in West Sussex. We cover Fernhurst, with the same fixed quotes and 12-month guarantee as everywhere else. Fernhurst is one of 373 places in West Sussex on our list for movement joints. Our Portsmouth page has more on work in that area.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on 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 Fernhurst, 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 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.

Before we start on site

  • Confirm the product named in the specification
  • Move anything stored against the joints
  • Let building users know which areas are affected

Getting a fixed quote

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Related advice

After the work

Problems stay small when the joints are checked regularly. In particular:

  • Keep product details with the building records for the next reseal
  • Keep scrapers and ploughs from dragging across joint sealant
  • Reopen bays and walkways only after the stated cure time
  • Inspect movement joints alongside other routine building checks

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.

Common problems we fix in Fernhurst

Car park decks and floors face loads that walls never see. Tyres and wheels press on the edges and the sealant, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.

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

  • Damp inside where a wall movement joint has failed
  • Joints packed with grit and debris
  • Chipped joint edges on forklift routes
  • Hardened, cracked sealant on exposed facades

If you manage units on an estate such as Hurstfold Industrial Estate, which lies south-east of Fernhurst, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.
