Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Inspect movement joints alongside other routine building checks
- Inspect exposed joints once the cold weather has passed
- Keep stones and debris out of open joint lines
- Treat a small split as a warning, not a cosmetic issue
Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
About our expansion joint sealing in Nethermill
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you are dealing with layers of sealant in a movement joint and joints packed with grit and debris, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Nethermill, that means joint design, primers and backing rod as standard.
For floor or movement joints around smaller places like Nethermill, we plan to finish in one visit where we can. Photos, approximate widths and what uses the floor help us bring the right materials.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Travel to smaller Scottish places like Nethermill is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. Outside work also needs a suitable weather window.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- Arrange parking or a loading space
- Make sure the joints can be reached
- Tell us which areas need to stay in use

Warehouse floors and decks around Nethermill
Being in the east of Scotland, Nethermill gets less rain than the west coast. Frost and de-icing salt still find their way into open external joints. Sealing them in drier months limits winter damage.
Around Nethermill, each joint gets a filler or sealant matched to what crosses it and how much it moves.

Common problems we fix in Nethermill
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Any of the following is a good reason to get the joints checked over:
- Water getting into the wall through a failed joint
- Sealant peeling off one face of the joint
- Car park joints leaking onto vehicles below
- Movement joints with split or torn sealant
Sites like Lochmaben Hospital (to the south-east of Nethermill) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Questions to ask before you book
- What site paperwork they can supply
- Will failed sealant be removed rather than covered?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- What the guarantee covers, and for how long
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
- The product specified
- Whether old sealant has to be cut out first
A quote for movement joints depends on how many there are, their condition and the access. Ask us for a fixed quote.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- The product your specification calls for
- Any dates the work must fit around
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
How the job changes by surface
Podium joints
Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.
Car park decks and ramps
Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again.
Your questions answered
Is Nethermill too small for you to travel to?
Not at all. Nethermill is within our area. Every Scottish council area is within our area. Good photos up front let us bring everything on the first visit.
Do we have to stop operations in Nethermill while the joints are sealed?
Normally not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
What exactly is a movement joint?
Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing, and either way it needs a sound seal.
Why do our movement joints keep failing?
The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first, because the fix differs.
Do you guarantee expansion joint work?
The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Keeping joints clear of debris helps them last.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you reseal car park expansion joints?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed.
What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Joints too narrow for the movement, which need redesigning by the engineer
- Damaged metal nosings or cover plates over a joint
- Waterproofing layers buried beneath the sealant
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we will tell you honestly.
