Expansion joint sealing in Sidlesham Common

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. Most enquiries involve layers of sealant in a movement joint and sealant peeling off one face of the joint, across precast concrete panel joints, podiums and floor movement joints and brickwork movement joints. A single leaking joint is often how a building in Sidlesham Common first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places such as Sidlesham Common, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Sidlesham Common

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears.

It’s worth sending us details if you spot any of the following:

  • Torn sealant in brick or block movement joints
  • Hardened, cracked sealant on exposed facades
  • Chipped joint edges on forklift routes
  • Leaks through car park deck joints onto the level below

Hospitals like St Richard's Hospital, 3.5 miles to the north of Sidlesham Common, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Before you book anyone

  • How they’ll work around occupants
  • Will failed sealant be removed rather than covered?
  • The terms of the workmanship guarantee
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

General trades versus a specialist

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Aftercare for building managers

To get the most from the new sealant:

  • Keep traffic off new joints until the cure time is up
  • Raise snow-clearing blades over deck joints where possible
  • Include every elevation and deck joint in periodic inspections
  • Record the sealant used and the date in the O&M file

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears. A routine sweep is the simplest protection.

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. Resealing promptly prevents internal damage.

Why it’s worth doing now in Sidlesham Common

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up. Acting at the first split keeps the cost down. Halls, stores and units around places like Sidlesham Common may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Slabs, ramps and loading bays in Sidlesham Common

Sidlesham Common sits close to the coast, within about 2 miles. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so a failed joint lets more in and the edges break up sooner. Sidlesham Common has at least three named business or industrial parks inside a 3-mile radius. Their warehouses, yards and car parks are exactly where joints take the most punishment.

For estates staff at a university like University of Chichester, which lies north of Sidlesham Common, building and paving joints are part of the planned maintenance list. For buildings at a park such as Enborne Business Park, which lies south of Sidlesham Common, brick and panel movement joints are easy to forget until one leaks.

Your questions answered

Is Sidlesham Common too small for you to travel to?

No. Small places get the same service as large ones. 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.

Would you work within a site like St Richard's Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How much does the work cost?

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

Quoting for work in Sidlesham Common

Before we quote, we look at:

  • Distance, for remote addresses
  • Removal of failed or old sealant
  • Whether the work must be split into stages
  • Access and working height

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Details that help us quote

There’s no need for a formal survey. These details are enough to start:

  • Clear photos of the problem areas
  • Anything awkward about access or site hours
  • Asbestos survey details if the building is older
  • When you need the work done

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Our process

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For work around Sidlesham Common, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • Flag any permit to work we’ll need
  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000
