Expansion joint sealing in Aston

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Smaller jobs around Aston can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  1. We assess the joints on site or from photographs, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  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. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Expansion joint sealing in Aston, done properly

Brickwork and blockwork walls have vertical movement joints at intervals. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied with primer where the maker calls for it. If you have car park joints leaking onto vehicles below and damp inside where a wall movement joint has failed, we can help. Whoever orders the work in Aston, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a site near Aston, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

Looking after the joints

A few simple habits keep the new joints working:

  • Plan racking layouts so feet don’t land on a joint
  • Reopen bays and walkways only after the stated cure time
  • Brief car park operatives to protect joint lines during winter clearance
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.

When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.

Different surfaces, different methods

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement.

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.

Commercial clients in Aston

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Joints that move: notes for Aston

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Central London is about 34 miles from Aston. Warehousing clusters around the motorways that ring and radiate from London.

For an estate such as Townlands Memorial Hospital, which lies south-west of Aston, the joints in ramps, decks and long building elevations all need attention over time. A campus such as University of Reading (to the south-west of Aston) has long runs of movement joint in its buildings, decks and paving.

Aston is about 2 miles north-east of Henley-on-Thames, in Wokingham. We cover Aston and the rest of Wokingham, with the same fixed quotes and 12-month guarantee as everywhere else. Aston is one of 42 places in Wokingham on our list. Reading is covered too, some 8 miles away.

Questions we are asked in Aston

Is a hospital such as Townlands Memorial Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Aston off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Do you reseal car park expansion joints?

Yes, we do. These joints take wheels, salt and water, so product choice matters.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing and both need a flexible seal.

How long does movement joint sealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. Typically it takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints.

Do you use silicone or polyurethane in movement joints?

The right product depends on the joint. 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.

When to bring in a specialist

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

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.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • How much existing material needs removing
  • Location, for remote and island sites
  • Whether the work must be split into stages
  • Quantities, in metres or numbers

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Whether an asbestos survey exists
  • Any specification or named product
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we will arrange one.
