Need expansion joint sealing in Nyton?

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

What happens if it’s left?

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. We’ll flag where edges need repair before sealing. One visit to deal with every failing joint makes more sense than several trips to a place like Nyton, rather than one at a time. Send photos of each area and we will quote for the lot.

The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.

Expansion joint sealing in Nyton, done properly

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. Most enquiries involve sealant peeling off one face of the joint and expansion joints split through the centre of the bead, across car park decks and ramps, cladding panel joints and podiums and floor movement joints. For commercial sealant work in Nyton, you deal with one contact from quote to sign-off, whether it’s one building or several.

Around smaller places such as Nyton, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

General trades versus a specialist

Redoing a failed joint typically costs more than getting it right at the outset, 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.

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 where general trades tend to cut corners.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Nyton may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints
  • Have the specification and drawings to hand

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Leaks coming from the membrane rather than the joint seal
  • Cracking or settlement that calls for an engineer’s assessment

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Surfaces we seal

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

Slabs, ramps and loading bays in Nyton

Nyton lies roughly 52 miles out 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. The South East is one of the drier 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.

Across sites such as Chichester Business Park., which lies north-west of Nyton, floor and movement joints can be sealed in phases so units keep working. A campus such as University of Chichester (2.6 miles south-west of Nyton) has long runs of movement joint in its buildings, decks and paving. On a site such as The Woodhorn Business Centre, 1.5 miles to the west of Nyton, the movement joints are in car park slabs, paving and building elevations.

Nyton is about 4 miles north of Bognor Regis, in West Sussex. Any commercial site in Nyton is covered. 373 places across West Sussex fall within our area, Nyton among them. Sites around Portsmouth have their own page, roughly 18 miles from Nyton.

Commercial clients in Nyton

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.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Different surfaces, different methods

Cladding panel joints

We confirm what access is in place before pricing. Close-up photos help us judge the joints or a site visit fills the gaps.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler.
