What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Glazing units that are cracked or misted
- Damage to finishes by other trades after we’ve sealed
- Deciding which fire-stopping product a penetration needs
Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly.

Construction mastic in Racks, done properly
The specification and the programme set the job rather than whatever product is to hand. If a product is named, that’s what goes in. Backing, primer and depth follow what the sealant maker sets out. If you have inconsistent sealant finishes from plot to plot and a long mastic snag list close to completion, we can help, on brick and block movement joints, cladding and panel joints and window and door perimeters alike. Facilities teams, main contractors and managing agents in Racks tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Sites near smaller places like Racks can mean longer travel, so the mastic is planned with as few trips as the job allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
Every job we finish is backed by a 12-month workmanship guarantee, in Racks as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Advice
Leave it or put it right?
Clearing snags piecemeal is tempting when handover is close. But one planned snagging pass through each area normally clears more for less disruption, and avoids repeated visits. Snagging can be priced as a separate stage. Renewing every failing joint on one visit is the sensible approach for a place like Racks. Photos of each area help us quote the whole job.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

How the job changes by surface
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. We use the specified perimeter sealant, typically a low-modulus neutral-cure silicone, with backing rod in deeper gaps.
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. Joints are sealed smooth so they’re easy to clean.
After the work
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Stick to the specified sealant rather than a generic substitute
- Keep finished joints away from paint, plaster and scrapers
- Release areas for mastic once other trades have finished in them
- Allow flexibility for external sealing in damp or cold weather
The package carries our 12-month guarantee for workmanship. Damage by others isn’t a workmanship fault, so protecting sealed areas matters.
In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Leaks behind showers and basins damage finishes and floors, and the repair falls into the defects period. Proper preparation, with the right silicone first time, keeps it off the defects list.
Construction mastic around Racks: how the place shapes the job
The east of Scotland, where Racks is, gets less rain than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. We programme around it with the site team. Scotland has its own building regulations, and in Racks warrants come from the local authority verifier. The mastic package follows the approved specification.
On a campus such as Crichton University Campus, which lies west of Racks, new teaching buildings and residences are typically built and refurbished around the academic year. On a healthcare site such as Midpark Hospital, 2.8 miles west of Racks, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Projects at colleges like Dumfries & Galloway College - Dumfries Campus, 2.7 miles west of Racks, tend to run to term dates, so the mastic is planned tightly.
Racks is about 4 miles east of Dumfries, in Dumfries and Galloway. Any commercial site in Racks is covered. Our Dumfries and Galloway coverage takes in 139 places, from busy centres to rural villages. Glasgow is covered too, some 63 miles away.

Common questions from Racks clients
Is a smaller place like Racks outside your area?
No. Places such as Racks are covered as much as the big towns. We work across every Scottish council area. Good photographs up front let us bring everything on the first visit.
Do you take on work at healthcare sites like Midpark Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. Our office runs Monday to Friday, 8am until 5pm.
What guarantee comes with a mastic package?
The work is guaranteed for 12 months, covering how we sealed. Keeping other trades off finished joints prevents most problems.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
What about RAMS and site documents?
Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
