Expansion joint sealing in Church Norton

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing for commercial buildings in Church Norton

Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors. Site teams most often ask us about chipped joint edges on forklift routes and expansion joints split through the centre of the bead, across blockwork control joints, podiums and floor movement joints and brickwork movement joints. Facilities teams, main contractors and managing agents in Church Norton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Halls, schools and small commercial buildings near places like Church Norton have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Cracking or settlement that calls for an engineer’s assessment

If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think before you book.

Surfaces we seal

  • Cladding panel joints
  • Podiums and floor movement joints
  • Blockwork control joints
  • Brickwork movement joints
  • Car park decks and ramps
  • Precast concrete panel joints

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.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant
  • Working within restricted access windows
  • Location, for remote and island sites

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

Sending details for a quote

Good information means a firmer quote. Helpful details to send:

  • Whether the building will be occupied during the work
  • Any dates the work must fit around
  • The product your specification calls for
  • Anything awkward about access or site hours

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Different surfaces, different methods

Podium joints

Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal, and tell you if the problem looks like the waterproofing below.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.

Church Norton: questions and answers

Is a hospital such as Bognor Regis War Memorial Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Can being near the sea in Church Norton affect the sealant we need?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Can staff carry on working while you’re here?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Church Norton, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Make sure the joints can be reached
  • Share the asbestos register for older buildings
  • Warn occupants and staff about the work

Slabs, ramps and loading bays in Church Norton

With the shore within about 1 mile, Church Norton counts as a coastal location. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Rainfall across the South East, Church Norton included, is lower than in many parts of the UK. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

Hospital campuses such as Bognor Regis War Memorial Hospital, 5.1 miles to the north-east of Church Norton, grow in stages, leaving movement joints wherever new blocks meet old. Across sites such as Ferry Yard Industrial Park, 0.7 miles north-west of Church Norton, floor and movement joints can be sealed in phases so units keep working.

Do you need expansion joint sealing in Church Norton?

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.

Look out for the following:

  • Brittle, chalky sealant on external joints
  • Movement joints with split or torn sealant
  • Spalled or broken joint edges in floors and decks
  • Layers of sealant in a movement joint

Schools such as The Academy have movement joints in their walls and floors that are easy to overlook.
