Expansion joint sealing in Mount Pleasant

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Keeping the joints sound

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

  • Reopen bays and walkways only after the stated cure time
  • Include every elevation and deck joint in periodic inspections
  • Plan racking layouts so feet don’t land on a joint
  • Check joints after long freezing spells

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.

Expansion joint sealing in Mount Pleasant

Brickwork and blockwork walls have vertical movement joints at intervals that most people only notice when the sealant has gone. 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. We work on car park decks and ramps, cladding panel joints and podiums and floor movement joints, and the usual reasons a site gets in touch are water dripping through deck or ramp joints and rain penetration at brick or block movement joints. Most enquiries from Mount Pleasant start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

For a site near Mount Pleasant, 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.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Questions we’re asked in Mount Pleasant

Does your area include sites such as The Oaks Business Park, near Mount Pleasant?

Yes. We cover Mount Pleasant and the area around it, including industrial estates, business parks and retail parks such as The Oaks Business Park. To start, just speak to us on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Can you take on a job at a hospital such as Queen Elizabeth the Queen Mother Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

What if the joint edges are damaged?

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.

Do you use silicone or polyurethane in movement joints?

Movement capability matters most. Hybrid or MS polymer products suit some mixed-material joints.

What guarantee do you give on joint sealing?

Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.

Why do our movement joints keep failing?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. We diagnose which one it is before resealing since each needs a different fix.

Expansion joint sealing in Mount Pleasant: the local picture

The sea is no more than about 3 miles from Mount Pleasant. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Mount Pleasant sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

For an estate such as Queen Elizabeth the Queen Mother Hospital, 3.9 miles to the north-east of Mount Pleasant, the joints in ramps, decks and long building elevations all need attention over time. In a school such as Minster Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. At places like Manston Business Park, under half a mile to the north of Mount Pleasant, joints are sealed a section at a time so operations carry on.

What the job involves on each surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Concrete or masonry repairs along the arrises
  • Leaks coming from the membrane rather than the joint seal
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

If in doubt, phone 01277 525 020 or use the quote form and we’ll say what we think.

Surfaces we seal

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

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Mount Pleasant, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  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 tell you if the design looks wrong for the movement.
  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. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we’ll be in
  • Have the specification and drawings to hand

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, 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. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What happens if it’s left?

Re-sealing with the same product that failed is often a false economy. If the joint is too narrow or the product wrong for the movement, it needs a different approach and we will tell you honestly. For buildings around smaller places like Mount Pleasant, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

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 you’ll have a fixed figure to work with.
