Common problems we fix in Glenlochar
The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
What tends to prompt an enquiry:
- Hard, chalky sealant that no longer flexes
- Perimeter joints where frames meet the structure
- Unsightly perimeter sealant on a visible elevation
- Patch repairs that keep failing
School extensions, at buildings such as Castle Douglas High School, usually run to the summer holidays, mastic included.
Questions to ask before you book
- How the joint faces will be prepared and primed
- What the guarantee covers, and for how long
- Whether old or failed sealant will be cut out, not overlaid
- Who will actually carry out the work
About our facade sealing in Glenlochar
Managing agents and owners in Glenlochar ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. The enquiries we see most involve leaks at window and door perimeters and old perimeter mastic that has dried out, across shopfront frames, coping and flashing joints and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Glenlochar, that means joint design, primers and backing rod as standard.
For a site around Glenlochar, we plan the mastic in as few trips as the programme allows. Send drawings, photos and the programme so everything needed arrives on the first day.
Work we carry out in Dumfries and Galloway comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Mastic packages on Glenlochar sites
Being in the east of Scotland, Glenlochar gets less rain than the west coast. Cold, damp starts still stop external sealing on some days. External dates keep a little give. Projects in Glenlochar follow Scotland’s building regulations, with the local authority acting as verifier. The mastic package follows the approved specification.
Hotel extensions and refits, at places such as Culgruff House Hotel (1.5 miles north of Glenlochar), typically run between busy periods, so the sealing is squeezed into short windows. On a healthcare site such as Castle Douglas Hospital, 2.7 miles south-east of Glenlochar, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Building owners, agents and FMs in Glenlochar
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Glenlochar can form part of a wider programme across Dumfries and Galloway.

On site: what to expect
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Jobs near Glenlochar are often grouped with others in the same area, to make the most of each trip. Let us know if your dates have any give.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Preparing the site
- Tell us what induction or permit system the site runs
- Make sure the joints can be reached
- Have the specification and drawings to hand
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Record the product and colour used on each elevation
- Don’t wait for a second leak before calling
- Share access with other external trades
- Never let anyone seal over old sealant
After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
Your questions answered
Do you cover business parks and estates near Glenlochar, such as Abercromby Industrial Park?
Yes. We cover Glenlochar and the area around it, including industrial estates, business parks and retail parks such as Abercromby Industrial Park. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Glenlochar off your patch?
Not at all. Glenlochar is within our area. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on upper floors?
We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and the quote will reflect it.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What happens if it’s left?
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Glenlochar before they leak.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a fixed quote once you have the details.

- One phone line for London, the South East and Scotland
- Fully insured, including public liability cover

Should maintenance staff do it?
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.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
