How we handle expansion joint sealing in Kirkcowan
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant, 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 expansion joints filled with dirt and stones and rain penetration at brick or block movement joints, we can put it right. A single leaking joint is often how a building in Kirkcowan first comes to us: we look at the rest while we’re there and tell you what we find.
In smaller places such as Kirkcowan, the joints we’re asked about sit in workshops, farm sheds, schools and halls. Slabs and yards take vehicles, rain and frost.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Doing it in-house
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.
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. A poor seal in places like these tends to cost more to put right later.
Signs you need expansion joint sealing in Kirkcowan
Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.
Look out for the following:
- Chipped joint edges on forklift routes
- Water dripping through deck or ramp joints
- Water getting into the wall through a failed joint
- Torn sealant in brick or block movement joints
Large sites such as Newton Stewart Hospital (to the north-east of Kirkcowan) have car parks, service roads and long elevations with movement joints in brick and panels.
What your quote should include
- How joint depth will be controlled
- Proof of insurance

Common questions from Kirkcowan clients
Will our site in Kirkcowan have to close for joint sealing?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
Is Kirkcowan off your patch?
Not at all. Kirkcowan is within our area. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
What will the job cost?
There isn’t a price list, as every site differs. With photographs or drawings, we can give you a fixed quote.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Are expansion joints and movement joints the same thing?
The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably.
What sealant do you use in movement joints?
Movement capability matters most as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

Different surfaces, different methods
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement, and tell you if edges need repairing first.
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.
What happens if it’s left?
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Around smaller places like Kirkcowan, halls, stores and seasonal buildings may not be checked often, giving water time to get in. Early resealing prevents it.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
