Expansion joint sealing for New Hinksey sites

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

How a job runs

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. What matters most for a job in New Hinksey is a clear list of what needs doing. A fixed quote follows.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Let us know about inductions and permits
  • Have the specification and drawings to hand
  • For older buildings, check the asbestos register before work

Expansion joint sealing in New Hinksey, done properly

Long runs of brick or block have movement joints built in that most people only notice when the sealant has gone. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. We work on cladding panel joints, blockwork control joints and precast concrete panel joints, and the failures we’re asked to look at most are spalled or broken joint edges in floors and decks and hardened, cracked sealant on exposed facades. Whether you call it commercial sealant work, mastic application or joint sealing, in New Hinksey it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Rural business units around smaller places such as New Hinksey often have new slabs laid inside older buildings. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint usually 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.

Questions about New Hinksey

Do you cover business parks and estates near New Hinksey, such as Osney Mead Industrial Estate?

Yes. Estates, retail parks and business parks around New Hinksey, Osney Mead Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Is New Hinksey too far out for you?

Not at all. New Hinksey is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can a joint be sealed if the edges are broken?

Sealant needs sound faces to bond to, so we will tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Do you offer coloured sealant?

That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also ring 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Can you seal car park deck joints?

Yes. Tell us how the car park is used and which areas must stay open and we will plan around them.

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Inspect exposed joints once the cold weather has passed
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Reopen bays and walkways only after the stated cure time
  • Act on the first tear or lifting edge rather than waiting

Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.

Why act early in New Hinksey

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Why us?

  • Failed material removed, not covered up
  • Colours chosen to suit frames, cladding or finishes where possible

Slabs, ramps and loading bays in New Hinksey

New Hinksey lies roughly 52 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 gritting in cold spells finds its way into open joints.

Phasing is what makes joint work possible on busy sites such as Littlemead Business Park (1.3 miles north-west of New Hinksey): one bay, aisle or car park row at a time. Hospitals like Warneford Hospital (1.7 miles north-east of New Hinksey) have multi-storey or surface car parks whose joints carry vehicles round the clock. Warehouse floors on estates like Osney Mead Industrial Estate (1.1 miles north-west of New Hinksey) carry pallet trucks and forklifts over every saw-cut joint.
