Expansion joint sealing in Milton Heights, done properly

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. If you have arrises breaking up along floor joints and joints packed with grit and debris, we can help, on podiums and floor movement joints, blockwork control joints and cladding panel joints alike. One point of contact handles commercial sealant work in Milton Heights from the first photos to the final walk-round, for single jobs and planned programmes alike.

Jobs around smaller places like Milton Heights are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we will take it from there.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Do you need expansion joint sealing in Milton Heights?

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.

Typical triggers for a call:

  • Water getting into the wall through a failed joint
  • Spalled or broken joint edges in floors and decks
  • Expansion joints filled with dirt and stones
  • Car park joints leaking onto vehicles below

A healthcare site such as Didcot Hospital, 2 miles south-east of Milton Heights, depends on car parks, ramps and service yards whose joints take traffic all day.

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep racking legs and heavy point loads off floor joints
  • Treat a small split as a warning, not a cosmetic issue
  • Record the sealant used and the date in the O&M file
  • Keep scrapers and ploughs from dragging across joint sealant

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. A routine sweep is the simplest protection.

On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. That water often carries de-icing salts with it, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Damaged metal nosings or cover plates over a joint
  • Waterproofing layers buried beneath the sealant
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Questions about Milton Heights

Is The Core Business Centre, near Milton Heights, within your area?

Yes, sites like The Core Business Centre are within our area, along with the rest of Milton Heights. Send details of the unit and the work through our quote form for a quick quote.

Do you take on work at healthcare sites like Didcot Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you fit around our working hours?

Give us your site hours and any 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.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Is any job too small?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

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. On site, people tend to use them interchangeably and the way they’re sealed is similar.

Do you work in Milton Heights?

Yes. We cover Milton Heights and the rest of Oxfordshire, within our coverage of Greater London, South East England and Scotland. To discuss a job, phone 01277 525 020 or email a schedule or drawings.

When to bring in a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

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 easy to get wrong without experience.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you. Jobs in and around smaller places like Milton Heights are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  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 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. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Clear stock, furniture or equipment away from the joints
