How we handle expansion joint sealing in Fontwell

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. Site teams most often ask us about weathered movement joint sealant that no longer flexes and new sealant over old, now failing, on cladding panel joints, blockwork control joints and brickwork movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Fontwell is the same: the right product in a properly prepared joint.

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

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Commercial clients in Fontwell

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Questions we are asked in Fontwell

Is a smaller place like Fontwell outside your area?

Not at all. Fontwell is within our area. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is hospital work, at somewhere like Arundel and District Hospital, something you do?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What will the job cost?

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

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you work on car park ramps and decks?

Yes. Let us know the opening hours and which levels or bays have to stay available, and we will plan the phasing around it.

Leave it or put it right?

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. If the edges have broken up, we will tell you they need repairing first. One visit to deal with every failing joint makes more sense than several trips to a place like Fontwell, rather than one at a time. Send photos of each area and we will quote for the lot.

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 clients in Fontwell choose us

  • Our applicators hold CSCS cards
  • Colours chosen to suit frames, cladding or finishes where possible
  • Work to your specification and the manufacturer’s guidance
  • A range of standard colours, depending on the product

Common problems we fix in Fontwell

Sometimes the sealant holds but the substrate breaks away. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Things that usually lead to an enquiry:

  • Water getting into the wall through a failed joint
  • Layers of sealant in a movement joint
  • Expansion joints split through the centre of the bead
  • Chipped joint edges on forklift routes

Sites like Arundel and District Hospital (3.7 miles east of Fontwell) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Our contractor checklist

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Smaller jobs around Fontwell can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. A fixed quote names the sealant we propose and its movement class.
  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. 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

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Tell us which areas need to stay in use

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or give us a call on 01277 525 020 or email us to discuss it first.

Expansion joint sealing around Fontwell: points for this area

Fontwell sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Fontwell is about 51 miles from central London. Warehousing clusters around the motorways that ring and radiate from London.

At places like Sussex Business Village, which lies south-east of Fontwell, joints are sealed a section at a time so operations carry on. Campuses like University of Chichester (to the south-west of Fontwell) mix old and new buildings, with movement joints wherever they meet.

Fontwell is about 5 miles north of Bognor Regis, in West Sussex. We send applicators to Fontwell for movement joints. We work across 373 places in West Sussex. For work in that direction, see our Portsmouth page (19 miles or so).

How the quote is worked out

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

  • Joint width, depth and condition
  • Location, for remote and island sites
  • Access and working height
  • How much existing material needs removing

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • A wide shot and a close-up of the area
  • Specification clauses that apply
  • Any dates the work must fit around
  • Whether an asbestos survey exists

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
