Expansion joint sealing in Flansham, done properly

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in. We work on blockwork control joints, brickwork movement joints and precast concrete panel joints, and the failures we’re asked to look at most are sealant peeling off one face of the joint and water dripping through deck or ramp joints. Whoever orders the work in Flansham, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Jobs around smaller places like Flansham are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Common questions from Flansham clients

Is Flansham off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Bognor Regis War Memorial Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

How long does movement joint sealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Is movement joint sealing guaranteed?

It’s backed by our 12-month guarantee. If a joint we sealed fails inside the 12 months, let us know.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Traffic, movement and joints around Flansham

The sea is no more than about 2 miles from Flansham. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. Central London is about 54 miles from Flansham. The roads out of London are lined with trade parks and distribution sheds.

University campuses such as University of Chichester (Bognor Campus) (to the south-west of Flansham) have car parks, paved walkways and building elevations with movement joints. Warehouse floors on estates like Southern Cross Trading Estate (1.1 miles west of Flansham) carry pallet trucks and forklifts over every saw-cut joint. For an estate such as Bognor Regis War Memorial Hospital (1.7 miles south-west of Flansham), the joints in ramps, decks and long building elevations all need attention over time.

Flansham is about 2 miles north-east of Bognor Regis, in West Sussex. Anywhere in PO22, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Flansham is one of 373 places we cover in West Sussex. Portsmouth is covered too, some 19 miles away.

Commercial sites across PO22 are covered. We also cover Bilsham (1 mile east), Lidsey (2 miles north-west), Shripney (2 miles west), Yapton (2 miles north-east) and Barnham (2 miles north). Further afield, our area takes in Worthing (11 miles east), Chichester (7 miles west), Selsey (8 miles south-west), Littlehampton (5 miles east), Lancing (14 miles east) and Rustington (6 miles east).

Local landmarks in Flansham

We work on buildings around Felpham Community College and The Brooks Local Nature Reserve, among other places. The closest station to Flansham is Barnham station, about 1.9 miles north. Nearby you’ll also find Tote Copse Castle (3.1 miles north-west) and Bognor Regis Museum (2.3 miles south-west).

Why it’s worth doing now in Flansham

On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use. We agree phasing with you before work starts. Older rural buildings around Flansham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

  • Commercial sealant work since 2005
  • CHAS accredited contractor

From enquiry to sign-off

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Flansham need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs

Commercial clients in Flansham

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, so there’s one set of paperwork to deal with.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Cost factors for movement joints

To price the job, we consider:

  • Quantities, in metres or numbers
  • Removal of failed or old sealant
  • Access and working height
  • The product specified

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.

Details that help us quote

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • The product your specification calls for
  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • Access details, including height

To get a fixed quote, speak to us on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

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. That’s why many clients bring in a specialist from the beginning.

After the work

Once the work is signed off, these steps help:

  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Reopen bays and walkways only after the stated cure time
  • Note which joints were done, when, and with what
  • Check joints after long freezing spells

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file, so the next reseal starts with the facts.

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.
