About our expansion joint sealing in Lesmahagow
Long runs of brick or block have movement joints built in 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 is cut away, backing rod goes in at depth, and a low-modulus masonry sealant is gunned and tooled, primed where the manufacturer specifies. We work on car park decks and ramps, brickwork movement joints and blockwork control joints, and the failures we are asked to look at most are water dripping through deck or ramp joints and water getting into the wall through a failed joint. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lesmahagow it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller Scottish places like Lesmahagow, slabs needing attention are often in agricultural buildings, workshops, schools and hotels. Concrete slabs and yards there take vehicles and weather.
Every job we finish is backed by a 12-month workmanship guarantee, in Lesmahagow as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Warehouse floors and decks around Lesmahagow
Being in the east of Scotland, Lesmahagow gets less rain than the west coast. Cold winters and gritting are hard on any yard or deck joint left open. Resealing before the cold months helps protect the edges.
Schools like Lesmahagow High School often have long brick elevations with movement joints that age quietly. Hospital campuses such as Birkwood Castle (to the south of Lesmahagow) grow in stages, leaving movement joints wherever new blocks meet old.

Why it’s worth doing now in Lesmahagow
A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Renewing every failing joint on one visit is the sensible approach for a place like Lesmahagow. Photos of each area help us quote the whole job.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Do you need expansion joint sealing in Lesmahagow?
On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.
Typical triggers for a call:
- Layers of sealant in a movement joint
- Rain penetration at brick or block movement joints
- Expansion joints filled with dirt and stones
- Torn sealant in brick or block movement joints
If you manage units on an estate such as Gateside Industrial Estate, which lies south of Lesmahagow, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.
What to look for in a quote
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
- What the guarantee covers, and for how long
- Whether primer will be used where the manufacturer specifies it
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, with the work itself normally taking a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Jobs near Lesmahagow are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Getting the site ready
- Tell staff and tenants when we will be in
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work

Keeping the joints sound
To get the most from the new sealant:
- Leave barriers in place until fresh joint sealant has cured
- Treat a small split as a warning, not a cosmetic issue
- Keep racking legs and heavy point loads off floor joints
- Keep product details with the building records for the next reseal
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.
What the job involves on each surface
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability, and we’ll confirm the colours available for the specified product.
