About our expansion joint sealing in Strettington

If you need expansion joint sealing in Strettington, start with photos and joint lengths. Send them through our quote form, and we’ll arrange a site visit if needed before issuing a fixed quote. You can also give us a call on 01277 525 020 or email us to talk the joints through. We work on car park decks and ramps, brickwork movement joints and blockwork control joints, and what we are called in for most is debris jammed in movement joints and hardened, cracked sealant on exposed facades. Facilities teams, main contractors and managing agents in Strettington tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

For a site near Strettington, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Why deal with it now?

Patching the worst lengths of a joint can make sense short term. But if the rest of the run is the same age and product, it’s typically not far behind. Where it helps, we quote both options. Halls, stores and units around places like Strettington 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.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why appoint us

  • Over 20 years of commercial sealing
  • Constructionline member for supplier checks
  • Colours confirmed for the specified product
  • Specification-led, product-correct work

Where floor joints take the most wear near Strettington

Strettington is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Strettington is about 52 miles from central London. The roads out of London are lined with trade parks and distribution sheds, and their floor joints take forklift and pallet-truck traffic all day.

Across sites such as Chichester Business Park., 1.1 miles east of Strettington, floor and movement joints can be sealed in phases so units keep working. For an estate such as St Richard's Hospital (1.9 miles south-west of Strettington), the joints in ramps, decks and long building elevations all need attention over time.

Strettington is about 2 miles north-east of Chichester, in West Sussex. We cover Strettington, with the same fixed quotes and 12-month guarantee as everywhere else. Strettington is one of 373 places in West Sussex on our list for movement joints. Sites around Portsmouth have their own page, roughly 15 miles from Strettington.

Business premises anywhere in PO18 are within our area for movement joints. We also cover Westerton (1 mile west), Waterbeach (1 mile north), Maudlin (1 mile south-west), Boxgrove (1 mile east) and Tangmere (1 mile south-east).

What we can’t put right

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

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Waterproofing layers buried beneath the sealant
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.

Surfaces we seal

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

Signs you need expansion joint sealing in Strettington

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises. The product has to be suited to the traffic.

What tends to prompt an enquiry:

  • Joints where the bead has lost adhesion
  • Damp inside where a wall movement joint has failed
  • Joints packed with grit and debris
  • Spalled or broken joint edges in floors and decks

Business parks such as Temple Bar Business Park (to the south of Strettington) have car parks, paved areas and long brick and panel elevations, all with movement joints.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • Which product they’ll use, and why it suits the joint
  • Their approach to joint depth and backing
  • Will RAMS and insurance details be available?

Our contractor checklist

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Jobs in and around smaller places like Strettington are normally planned as a single visit, so we ask for photographs 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.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

Advice

Different surfaces, different methods

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again, and we’ll tell you if any edges need repairing first.

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
