Expansion joint sealing near Brighstone

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

Diagnose, treat, sign off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Brighstone need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  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 flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  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.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions

Advice

How we handle expansion joint sealing in Brighstone

Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. The enquiries we see most involve weathered movement joint sealant that no longer flexes and sealant peeling off one face of the joint, on brickwork movement joints, car park decks and ramps and podiums and floor movement joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Brighstone is the same: the right product in a properly prepared joint.

Halls, schools and small commercial buildings near places like Brighstone have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

A 12-month guarantee applies to all our work in the Isle of Wight. Should something we installed fail, speak to us on 01277 525 020 or use the quote form and we’ll come back to it.

What happens if it’s left?

A torn seal left alone typically gets worse. Water and debris get in, the joint jams and the edges spall and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Converted and older buildings near places like Brighstone tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • One number for every site we cover
  • 12 months’ guarantee on every job
  • CHAS accredited
  • Products installed to the manufacturer’s instructions

Take a look at our cost guide or how we’re accredited.

What affects the price in Brighstone

To price the job, we consider:

  • The site’s rules and procedures
  • Whether the work must be split into stages
  • Joint width, depth and condition
  • Any access equipment needed

Pricing movement joints depends on quantities, condition and access. Call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. Helpful details to send:

  • The postcode of the building
  • When you need the work done
  • Access details, including height
  • Approximate linear metres or a joint schedule

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or send details through our quote form.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Waterproofing layers buried beneath the sealant

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

Joints and surfaces we work on

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

When to bring in a specialist

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.

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Questions about Brighstone

Is a smaller place like Brighstone outside your area?

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.

Our building in Brighstone is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Do you seal on top of existing sealant?

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

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we’ll plan around them.

Can you seal car park deck joints?

Yes. We use a sealant designed for wheel loads and the expected movement, and phased work can be planned so parts of the car park stay in use.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Expansion joint sealing around Brighstone: what changes locally

Brighstone sits close to the coast, within about 1 mile. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. Brighstone sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

For a school such as Brighstone Church of England Aided Primary School, playground and building joints can be done in the holidays. Hospitals like Whitecroft Hospital, 4.7 miles north-east of Brighstone, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Brighstone is about 6 miles south-west of Newport, in the Isle of Wight.
