Cost factors for movement joints

Quotes vary with the job. Expect it to depend on:

  • The total length or number of joints
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants

A quote for movement joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Sending details for a quote

We can often quote from photographs and a few details. It helps to include:

  • Photos of the joints, close up and from further back
  • Any specification or named product
  • The asbestos register, for older buildings
  • Access details, including height

Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email drawings and photos.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. For work around Mount Pleasant, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. We strip out the old seal and prepare the faces.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Make sure the joints can be reached
  • Point out parking and an unloading spot
  • Warn occupants and staff about the work

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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. That’s why many clients bring in a specialist from the beginning.

Traffic, movement and joints around Mount Pleasant

At about 40 miles from central London, Mount Pleasant is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Rainfall across the South East, Mount Pleasant 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, while winter salting gets into any joint left open.

A campus such as University of Sussex (3.2 miles north-west of Mount Pleasant) has long runs of movement joint in its buildings, decks and paving. For an estate such as Uckfield Community Hospital (4.2 miles north-east of Mount Pleasant), the joints in ramps, decks and long building elevations all need attention over time.

Mount Pleasant is about 4 miles north of Lewes, in East Sussex. Across the BN8 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee.

Mount Pleasant: questions and answers

Is a smaller place like Mount Pleasant outside your area?

Not at all. Mount Pleasant is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is a hospital such as Uckfield Community Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Why do our movement joints keep failing?

The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Broken edges are a third possibility.

How long does movement joint sealing take?

It typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Timings are set out in the quote.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Different surfaces, different methods

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. Everything is raked out before backing and sealant go in and flag any joint that seems undersized.

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.

What we’re called out for in Mount Pleasant

Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip so edge repair has to come before resealing.

If one of these sounds familiar, it’s time for a closer look:

  • Hardened, cracked sealant on exposed facades
  • Sealant peeling off one face of the joint
  • Expansion joints filled with dirt and stones
  • Layers of sealant in a movement joint

On industrial estates such as Diplocks industrial estate, 2.9 miles south-east of Mount Pleasant, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Questions to ask before you book

  • The named product and why it was chosen
  • Whether their applicators hold CSCS cards
  • How the joint faces will be prepared and primed
  • Their approach to joint depth and backing
