Expansion joint sealing in Balnacra
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 and the bead bonds to the sides, never the back. If you have spalled or broken joint edges in floors and decks and joints where the bead has lost adhesion, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Balnacra it comes down to the same thing: the right product in a properly prepared joint.
Weather windows decide external joint work around a place like Balnacra: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Our process
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Where we can, we combine work around Balnacra with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Agree which areas must stay open
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed

Advice
Common questions from Balnacra clients
What site paperwork comes with a job in Balnacra?
We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.
Do we have to stop operations in Balnacra while the joints are sealed?
Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.
What’s the difference between an expansion joint and a movement joint?
Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
What guarantee do you give on joint sealing?
Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.
Why do our movement joints keep failing?
It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Sometimes the edge material itself has failed.

Leave it or put it right?
A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

How the quote is worked out
These are the things that shape the price:
- Removal of failed or old sealant
- The size and state of each joint
- Travel to remote or island sites
- Access and working height
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
Sending details for a quote
However big the job, the same details help:
- Whether the building will be occupied during the work
- Photos of the joints, close up and from further back
- Where the site is, with the postcode
- The product your specification calls for
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or email drawings and photos.
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.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Note which joints were done, when, and with what
- Inspect exposed joints once the cold weather has passed
- Leave barriers in place until fresh joint sealant has cured
- Keep racking legs and heavy point loads off floor joints
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Resealing early limits the damage.
