Expansion joint sealing in Stedham

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

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

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.

About our expansion joint sealing in Stedham

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. Most enquiries involve car park joints leaking onto vehicles below and joints where the bead has lost adhesion, across podiums and floor movement joints, brickwork movement joints and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Stedham, preparation and product choice get the time they need.

Jobs around smaller places like Stedham are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. For work around Stedham, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Expansion joint sealing in Stedham: the local picture

Another example is Holmbush Industrial Estate (1.6 miles south-east of Stedham), where floors and yards would be done in stages around the occupiers. On a site such as Midhurst Business Centre, 1.2 miles south-east of Stedham, the movement joints are in car park slabs, paving and building elevations.

How the job changes by surface

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, usually low-modulus.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.

Common problems we fix in Stedham

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. The product has to be suited to the traffic.

Most enquiries start with one or more of the following:

  • Damp inside where a wall movement joint has failed
  • Joints packed with grit and debris
  • Chipped joint edges on forklift routes
  • Joints where the bead has lost adhesion

Schools such as Stedham Primary School have movement joints in their walls and floors that are easy to overlook.

Before you book anyone

  • How long is the guarantee, and what does it include?
  • What site paperwork they can supply
  • Which product they’ll use, and why it suits the joint
  • Their plan for phasing and protecting the area

Questions to ask before you appoint anyone

Cost factors for movement joints

These are the things that shape the price:

  • Working within restricted access windows
  • Access and working height
  • Site requirements such as inductions and permits
  • The size and state of each joint

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Sending details for a quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Rough lengths or quantities, or drawings if you have them
  • The asbestos register, for older buildings
  • The site address and postcode
  • Access details, including height

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email drawings and photos with what you know.

What we can’t put right

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • A joint that has to be widened or re-detailed before it can work
  • Waterproofing layers buried beneath the sealant
  • Movement on a scale no sealant is meant to absorb

If you are not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

What we seal

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

Stedham: questions and answers

Can you work on a hospital site such as Midhurst Community Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Midhurst Business Centre, near Stedham, within your area?

Yes. Estates, retail parks and business parks around Stedham, Midhurst Business Centre among them, are all within reach. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Does the weather affect joint sealing?

Weather matters for any external joint. Internal floor joints are far less affected.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Which product is best for expansion joints?

We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.
