How we handle expansion joint sealing in Bognor Regis

We have been sealing expansion and movement joints for over 20 years. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on brickwork movement joints, car park decks and ramps and precast concrete panel joints, and the failures we’re asked to look at most are car park joints leaking onto vehicles below and joints packed with grit and debris. A single leaking joint is often how a building in Bognor Regis first comes to us: we look at the rest while we’re there and tell you what we find.

Work on floor and movement joints in a large place such as Bognor Regis is normally phased: aisle by aisle or deck by deck, with areas handed back as each section cures.

Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

How the job changes by surface

Podium joints

Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in, and tell you if the joint looks too narrow for the movement.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. Sites in a big town such as Bognor Regis frequently have reception sign-in, inductions and permits to work. Send the site rules with your enquiry and we will plan to them.

  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. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  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.

What we need from you

  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed
  • Point out parking and an unloading spot

Your questions answered

Do you take on work at healthcare sites like Bognor Regis War Memorial Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Does a coastal location like Bognor Regis affect which sealant is used?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

How much does the work cost?

Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or use the quote form.

Is movement joint sealing guaranteed?

The 12-month guarantee applies to the workmanship. Tell us straight away if a joint we sealed gives trouble in that time.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

What we are called out for in Bognor Regis

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.

If one of these sounds familiar, it’s time for a closer look:

  • Movement joints with split or torn sealant
  • Debris jammed in movement joints
  • Spalled or broken joint edges in floors and decks
  • Rain penetration at brick or block movement joints

University campuses such as University of Chichester (Bognor Campus) (to the east of Bognor Regis) have car parks, paved walkways and building elevations with movement joints.

Choosing a commercial sealant contractor

Floors, slabs and movement joints in Bognor Regis

Bognor Regis is within about 1 mile of the coast. 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. At least three named trading, business or retail sites lie within about 3 miles of Bognor Regis. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

On industrial estates such as Durban Road Industrial Estate (0.8 miles north-east of Bognor Regis), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Hospitals like Bognor Regis War Memorial Hospital (0.5 miles east of Bognor Regis) have multi-storey or surface car parks whose joints carry vehicles round the clock.

Bognor Regis is in West Sussex. Businesses, contractors and managing agents in Bognor Regis can call on us for movement joints, as part of our coverage of West Sussex. Across West Sussex, 373 places are covered, Bognor Regis among them. Portsmouth is covered too, around 17 miles from Bognor Regis.

We take on movement joints across the PO21 and PO22 postcode area, whatever the building. We cover commercial and managed buildings on Station Road, London Road and Manet Square and the roads nearby.

For managing agents and facilities managers

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

Site staff or a sealant specialist?

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

Some joints are best left to specialists: 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.

What affects the price in Bognor Regis

Your fixed quote is built from the real scope. It takes account of:

  • How much there is to seal
  • Distance, for remote addresses
  • The size and state of each joint
  • The product specified

A quote for movement joints depends on quantities, condition and access. Ask us for a fixed quote.

What we need to price the job

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

  • The site address and postcode
  • Clear photographs of the problem areas
  • Rough lengths or quantities, or drawings if you have them
  • Your programme or deadline

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or send photos by email.
