About our expansion joint sealing in Chichester

We have been sealing expansion and movement joints for over 20 years for contractors, facilities managers and owners. 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. If you’re dealing with movement joints with split or torn sealant and joints where the bead has lost adhesion, we can help. A specialist sealant contractor works differently from a general builder: on jobs in Chichester, preparation and product choice get the time they need.

Car parks and yards in towns like Chichester take tyre loads and, in winter, de-icing salt. Catching a joint before its edges break is the simpler route.

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

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. In Chichester, as anywhere, the simplest time to fix a failed joint is before it leaks. After a leak, there’s drying, repairs and redecoration on top.

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.

Your questions answered

Does your area include sites such as City Business Park, near Chichester?

Yes. We cover Chichester and the area around it, including industrial estates, business parks and retail parks such as City Business Park. Photos and a short description are enough for a first look.

Must our site in Chichester stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Can staff carry on working while you’re here?

Typically, yes. We phase the work so most of the building stays in use.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Is movement joint sealing guaranteed?

Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and we clear our waste as we work. In a town such as Chichester, most jobs are single buildings. We start with your photos, drawings or a site visit, then send a fixed quote.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  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. Areas reopen once cured, and the work carries our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Have the specification and drawings to hand
  • Flag any permit to work we will need

Expansion joint sealing around Chichester: points for this area

The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. Less than 3 miles from Chichester there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Hospital campuses such as St Richard's Hospital, 0.5 miles north-east of Chichester, grow in stages, leaving movement joints wherever new blocks meet old. Phasing is what makes joint work possible on busy sites such as Terminus Industrial Estate (0.7 miles south-west of Chichester): one bay, aisle or car park row at a time. Centres like Summersdale Retail Park (1.3 miles north of Chichester) have mall floors and service decks whose joints carry steady traffic.

Chichester is about 27 miles east of Southampton, in West Sussex. Chichester sits inside our coverage and the rest of West Sussex, with the same fixed quotes and 12-month guarantee as everywhere else. Chichester is one of 373 places in West Sussex on our list for movement joints. Our Portsmouth page has more on work in that area (13 miles or so).

Work on movement joints is covered throughout PO19, PO20, PO18 and PO10, for business premises of every kind.

Nearby places we also cover include Portfield (1 mile east), Westhampnett (1 mile north-east), Shopwyke (2 miles east), Maudlin (2 miles north-east) and East Lavant (2 miles north) for movement joints. Further afield, our area takes in Bognor Regis (5 miles south-east), Selsey (7 miles south), Littlehampton (11 miles east), Rustington (12 miles east), Storrington (15 miles east) and Angmering (13 miles east).

Maintenance after handover

Once the work is signed off, these steps help:

  • Inspect movement joints alongside other routine building checks
  • Inspect exposed joints once the cold weather has passed
  • Record the sealant used and the date in the O&M file
  • Raise snow-clearing blades over deck joints where possible

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Surface by surface

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

What sets the cost

The price varies from site to site. It mainly depends on:

  • Any access equipment needed
  • Which sealant the job calls for
  • Location, for remote and island sites
  • Site requirements such as inductions and permits

We don’t publish prices, since every building and every scope is different. Call for a quote.

What to include in your enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • What the building is and how it’s used
  • How the joints are reached, and at what height
  • Your programme or deadline
  • Where the site is, with the postcode

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
