About our expansion joint sealing in Shirburn

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled. Site teams most often ask us about sealant peeling off one face of the joint and rain penetration at brick or block movement joints, across car park decks and ramps, podiums and floor movement joints and brickwork movement joints. A specialist sealant contractor works differently from a general builder: on jobs in Shirburn, preparation and product choice get the time they need.

Jobs around smaller places like Shirburn are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal
  • Cracking or settlement that calls for an engineer’s assessment

If in doubt, call 01277 525 020 or email drawings and photos and we will say what we think before you book.

Where we work in Shirburn

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

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What affects the price in Shirburn

To price the job, we consider:

  • Which sealant the job calls for
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first
  • Induction, permit and paperwork requirements

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Whether an asbestos survey exists
  • The postcode of the building
  • Drawings or a marked-up plan, if available
  • The type of building and who uses it

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Your questions answered

Do you cover business parks and estates near Shirburn, such as Watlington Industrial Estate?

Yes. Our area takes in Shirburn and its surroundings, with estates and business parks such as Watlington Industrial Estate included. A few photos and the unit address let us price the work.

Must our site in Shirburn stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

What guarantee do you give on joint sealing?

Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.

Can you work on car park ramps and decks?

Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we’ll tell you if any edges need repairing first.

Are you insured?

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

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading while the sealant stops grit and water getting in.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Warehouse floors and decks around Shirburn

Shirburn sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. At about 40 miles from central London, Shirburn is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

Warehouse floors on estates like Watlington Industrial Estate (1.2 miles south-west of Shirburn) carry pallet trucks and forklifts over every saw-cut joint.

Shirburn is about 6 miles south of Thame, in Oxfordshire. Commercial clients in Shirburn use us for work on movement joints. Our Oxfordshire coverage takes in 423 places. Oxford is covered too, some 12 miles away.

What happens if it’s left?

Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s normally not far behind, and a second visit means paying for access again. We can price a patch and a full reseal side by side. Older rural buildings around Shirburn move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why appoint us

  • Workmanship guaranteed for 12 months
  • A Constructionline member, so easy to vet
  • A fixed quote before work starts
  • Sealing commercial buildings since 2005

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Shirburn are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Share your working hours and any access restrictions
  • Flag any permit to work we’ll need

What we are called out for in Shirburn

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way, so we check width and movement before quoting.

Look out for the following:

  • Brittle, chalky sealant on external joints
  • Debris jammed in movement joints
  • Damp inside where a wall movement joint has failed
  • Sealant peeling off one face of the joint

For a school such as Icknield Community College, playground and building joints can be done in the holidays.

What your quote should include

  • How joint depth will be controlled
  • Whether primer will be used where the manufacturer specifies it
  • The named product and why it was chosen
  • Will CSCS-carded applicators be on site?
