Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Expansion joint sealing for commercial buildings in Banbury

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. Most enquiries involve debris jammed in movement joints and rain penetration at brick or block movement joints, across precast concrete panel joints, brickwork movement joints and car park decks and ramps. Whether you call it commercial sealant work, mastic application or joint sealing, in Banbury it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Car parks and yards in towns like Banbury take tyre loads and, in winter, de-icing salt. Resealing before the edges break up is far less disruptive than repairing them later.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common problems we fix in Banbury

Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.

Typical triggers for a call:

  • Torn sealant in brick or block movement joints
  • Hardened, cracked sealant on exposed facades
  • Joints where the bead has lost adhesion
  • Rain penetration at brick or block movement joints

Another example is Southam Road Retail Park, 0.7 miles to the north-east of Banbury, where floors and yards would be done in stages around the occupiers.

Before you book anyone

  • Proof of insurance
  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
  • Whether primer will be used where the manufacturer specifies it

How to choose a sealant contractor

Your questions answered

Will our site in Banbury have to close for joint sealing?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.

Can you work at a site such as Swan Industrial Estate, by Banbury?

Yes. Estates, retail parks and business parks around Banbury, Swan Industrial Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How much does the work cost?

Each job is quoted on its own details. To get one, phone 01277 525 020 or email the details over with a description of the work.

Can you send site paperwork?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Different surfaces, different methods

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.

Joints between different materials

Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

Looking after the joints

Once the work is signed off, these steps help:

  • Check joints after long freezing spells
  • Avoid parking heavy plant or pallets on joint lines
  • Clear dirt from joint lines during routine cleaning
  • Note which joints were done, when, and with what

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.

Leave it or put it right?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. We agree phasing with you before work starts. A failed joint is easier to put right before damp shows inside. Once water gets in, there’s drying out and making good as well.

The price depends on the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Expansion joint sealing around Banbury: points for this area

Less than 3 miles from Banbury there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Banbury is in the South East, one of the UK’s drier regions. 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.

Large sites such as The Horton General Hospital, 0.8 miles to the south-east of Banbury, have car parks, service roads and long elevations with movement joints in brick and panels. In a school such as St Mary's Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

On site: what to expect

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 we move to the next. For a town like Banbury, we try to group jobs for the same client into one visit, with one quote covering them. Give us your access times and we’ll fit the work in.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, flagging any broken edges that need repair before sealing.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.
