Your questions answered
Will our site in Dumfries have to close for joint sealing?
Usually not: we work in sections and hand each one back once it has cured. The phasing plan comes with the quote.
Would you work within a site like Midpark Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Can staff carry on working while you’re here?
Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.
Why has the sealant in our expansion joints split?
The way it has failed usually tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Slabs, ramps and loading bays in Dumfries
Dumfries is on Scotland’s drier eastern side. Freezing weather and salt still attack open external joints. Sealing them before winter limits the damage. At least three named trading, business or retail sites lie within about 3 miles of Dumfries. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Hospital campuses such as Midpark Hospital (to the south-east of Dumfries) grow in stages, leaving movement joints wherever new blocks meet old. At places like Cuckoo Bridge Retail Park (0.8 miles north-west of Dumfries), joints are sealed a section at a time so operations carry on. Schools like Dumfries Academy often have long brick elevations with movement joints that age quietly.

What we can’t put right
We check first that sealant really is the fix. It isn’t the answer for:
- Crumbling edges that would give a new bead nothing sound to grip
- Damaged metal nosings or cover plates over a joint
- A joint that has to be widened or re-detailed before it can work
If you are not sure, just phone 01277 525 020 or use the quote form and we’ll give you a straight answer.
Where we work in Dumfries
- Car park decks and ramps
- Blockwork control joints
- Precast concrete panel joints
- Podiums and floor movement joints
- Brickwork movement joints
- Cladding panel joints
Maintenance after handover
After handover, these steps help:
- Inspect movement joints alongside other routine building checks
- Inspect exposed joints once the cold weather has passed
- Reopen bays and walkways only after the stated cure time
- Brief car park operatives to protect joint lines during winter clearance
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears. Regular sweeping keeps joint lines clear.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles. Resealing early limits the damage.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. If you manage more than one building in Dumfries, they can be grouped, with one quote. Share your working hours and access arrangements and we will fit in.
- We assess the joints on site or from photos, noting widths and how each has failed.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Confirm the product named in the specification
- Share your working hours and any access restrictions
- Tell us which areas need to stay in use

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
Related advice
How the job changes by surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it.
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
Why it’s worth doing now in Dumfries
Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. In Dumfries, rain and frost work into any failed joint, and the damage spreads from there. Resealing early keeps it a simple job.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.
