Expansion joint sealing for commercial buildings in Owlsmoor

We’ve been sealing expansion and movement joints for over 20 years. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on blockwork control joints, brickwork movement joints and precast concrete panel joints, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and water dripping through deck or ramp joints. Whoever orders the work in Owlsmoor, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around places the size of Owlsmoor, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Work for main contractors and building owners

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

We work for building owners and managing agents on everything from one building to a spread of sites around Owlsmoor. Several sites can go on one quote, which keeps the paperwork simple.

Your questions answered

Is a smaller place like Owlsmoor outside your area?

Not at all. Owlsmoor is within our area. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work at a site such as Wellington Business Park, by Owlsmoor?

Yes. We cover Owlsmoor and the area around it, including industrial estates, business parks and retail parks such as Wellington Business Park. A few photographs and the unit address let us price the work.

What timescale should we allow for resealing expansion joints?

It typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. We confirm the timescale with the quote.

How do you deal with asbestos in old sealant?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

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

The general name is movement joint, and expansion joint is one common type. In everyday use the two names are often swapped, and the sealing method is much the same.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Can you work to our specification?

Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.

Expansion joint sealing in Owlsmoor: the local picture

Less than 3 miles from Owlsmoor there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment. Rainfall across the South East, Owlsmoor included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

For a school such as Owlsmoor Primary School, playground and building joints can be done in the holidays. Sites like Broadmoor Hospital, 0.8 miles north of Owlsmoor, carry ambulances, deliveries and visitors’ cars over their road and deck joints. On a site such as Wellington Business Park, which lies west of Owlsmoor, the movement joints are in car park slabs, paving and building elevations.

Owlsmoor is about 1 mile north of Sandhurst, in Bracknell Forest. Commercial clients in Owlsmoor use us for work on movement joints. Owlsmoor is one of 48 places in Bracknell Forest on our list. We also cover Reading, some 10 miles away.

How the job changes by surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately or a site visit fills the gaps.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.

Our process

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. If neighbouring businesses or buildings around Owlsmoor need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Flag any permit to work we’ll need

Related advice

After the work

Once the work is signed off, a little attention goes a long way:

  • Inspect movement joints alongside other routine building checks
  • Check joints after long freezing spells
  • Avoid parking heavy plant or pallets on joint lines
  • Brief car park operatives to protect joint lines during winter clearance

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, call 01277 525 020 or email us with photographs.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Cost factors for movement joints

A fixed quote reflects the actual work. It allows for:

  • Travel to remote or island sites
  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures
  • Any access equipment needed

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What to include in your enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older
  • When you need the work done
  • Any specification or named product

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
