How we handle expansion joint sealing in Barcombe Cross

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it and we name it in the quote. Most enquiries involve chipped joint edges on forklift routes and previous reseals laid over old sealant, across precast concrete panel joints, blockwork control joints and cladding panel joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Barcombe Cross is the same: the right product in a properly prepared joint.

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

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What the job involves on each surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing, and our waste is bagged and taken away as we go. Smaller jobs around Barcombe Cross can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Questions about Barcombe Cross

Will you take on work at estates like Diplocks industrial estate, close to Barcombe Cross?

Yes. We cover Barcombe Cross and the area around it, including industrial estates, business parks and retail parks such as Diplocks industrial estate. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is a hospital such as Lewes Victoria Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you use silicone or polyurethane in movement joints?

The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class so there are no surprises.

Can you seal car park deck joints?

Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed and broken edges are flagged before sealing.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or send details through our quote form. Include photos or drawings if you have them.

Can you work while the building is occupied?

Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

When to call us in Barcombe Cross

Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.

Most enquiries start with one or more of the following:

  • Water getting into the wall through a failed joint
  • Expansion joints filled with dirt and stones
  • Chipped joint edges on forklift routes
  • New sealant over old, now failing

If you manage units on an estate such as Diplocks industrial estate (2.6 miles south-east of Barcombe Cross), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Before you book anyone

  • The named product and why it was chosen
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Are they CHAS accredited or on Constructionline?
  • How they’ll work around occupants

Questions to ask before you appoint anyone

Commercial clients in Barcombe Cross

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

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.

Slabs, ramps and loading bays in Barcombe Cross

Barcombe Cross lies roughly 40 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.

Schools such as Barcombe Church of England Primary School have movement joints in their walls and floors that are easy to overlook. A campus such as University of Sussex (to the north-west of Barcombe Cross) has long runs of movement joint in its buildings, decks and paving.

Barcombe Cross is about 3 miles north of Lewes, in East Sussex.

What happens if it’s left?

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex. Full removal and preparation is in every quote. Older rural buildings around Barcombe Cross move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

General trades versus a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
