Why act early in Steeple Aston

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall. Resealing early keeps the work to sealant. Older rural buildings around Steeple Aston move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Why appoint us

  • Work carried out by CSCS-carded applicators
  • Over 20 years of commercial sealing
  • A fixed quote before work starts
  • 12 months’ guarantee on every job

Expansion joint sealing for commercial buildings in Steeple Aston

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Without a sound filler, joint edges chip and spall under load. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. If you’re dealing with new sealant over old, now failing and leaks through car park deck joints onto the level below, we can put it right. Looking for mastic applicators who cover Steeple Aston? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

In and around smaller places like Steeple Aston, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Quoting for work in Steeple Aston

The price varies from site to site. Expect it to depend on:

  • How accessible the joints are
  • The site’s rules and procedures
  • Working within restricted access windows
  • Distance, for remote addresses

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What we need to price the job

There’s no need for a formal survey. These details are enough to start:

  • Whether the building will be occupied during the work
  • Where the site is, with the postcode
  • Any specification or named product
  • The asbestos register, for older buildings

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email the details over.

Where floor joints take the most wear near Steeple Aston

Steeple Aston lies roughly 60 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Steeple Aston 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, and winter de-icing salt on car parks and ramps works into any open joint.

Warehouse floors on estates like Hatch End Old Industrial Estate, less than half a mile to the north of Steeple Aston, carry pallet trucks and forklifts over every saw-cut joint. In a school such as Dr Radcliffe's Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

FAQs: Steeple Aston

Does a site in Steeple Aston have to shut while its joints are sealed?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Is Steeple Aston too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What sealant do you use in movement joints?

It depends on the movement, exposure and traffic. Low-modulus neutral-cure silicone suits many facade joints, while polyurethane is common in trafficked floor and deck joints unless the specification names something else.

What guarantee do you give on joint sealing?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

Do the joint edges need to be sound before sealing?

Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.

What’s the difference between an expansion joint and a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.

Can you quote from photographs?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep product details with the building records for the next reseal
  • Check joints after long freezing spells
  • Raise snow-clearing blades over deck joints where possible
  • Put movement joints on the planned maintenance inspection round

Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can call 01277 525 020 or send details through our quote form and send a picture.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. Rural sites near Steeple Aston may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
  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. Each joint is inspected and handed over with our 12-month guarantee.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot
  • Clear stock, furniture or equipment away from the joints

Advice

Honest limits

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Proprietary pre-formed expansion joint systems
  • Joints too narrow for the movement, which need redesigning by the engineer

If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think.

What we seal

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