Facade sealing in Colliston, done properly
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. We work on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints, and the usual reasons a site gets in touch are weathered joints at frame-to-structure perimeters and cladding panel joints that have opened up. For commercial sealant work in Colliston, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For a site around Colliston, we plan the mastic in as few trips as the programme allows. Clear drawings, a programme and photos let us bring the right sealants, primers and backing rod first time.
Work we carry out in Angus comes with a 12-month guarantee. If an installation problem shows up, call 01277 525 020 or use the quote form and we will arrange a return visit.

Colliston: questions and answers
Can you work at a site such as Kirkton Industrial Estate, by Colliston?
Yes. Our area takes in Colliston and its surroundings, with estates and business parks such as Kirkton Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Do you take on work at healthcare sites like Hospital of St John the Baptist?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you need to see the site first?
That depends on the size and complexity of the job. Simple work can often be priced from photographs, and bigger or more complex jobs normally get a visit.
How is access to upper-level joints handled?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we’ll price the work around it.
How do we ask for a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Facades, frames and programmes in Colliston
The east of Scotland, where Colliston is, gets less rain than the west. Frost and condensation on frames and panels can still hold up external mastic on winter mornings. We agree external dates with the site team and keep internal work ready. Building work in Colliston comes under the Building (Scotland) Regulations 2004 and their technical handbooks, with warrants from the local authority verifier. Our job is to seal to that specification.
On a healthcare site such as Hospital of St John the Baptist, 3 miles to the south-east of Colliston, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. New units and refits on sites such as Kirkton Industrial Estate (2 miles south-east of Colliston) need their panel and perimeter joints sealed to the specification.
Colliston is about 3 miles north-west of Arbroath, in Angus. We send applicators to Colliston for facade joints, handled exactly as we handle every other area. Across Angus, 65 places are covered, including Colliston. Dundee is covered too, some 15 miles away.

If your building is just outside Colliston, we cover St Vigeans (2 miles south-east), Arbroath (3 miles south-east), Friockheim (3 miles north), Balmirmer (4 miles south-west) and Inverkeilor (5 miles north-east). Further afield, our area takes in Forfar (10 miles west), Montrose (11 miles north-east), Monifieth (10 miles south-west), Carnoustie (7 miles south-west), Kirriemuir (15 miles west) and Brechin (10 miles north).

What affects the price in Colliston
There’s no standard rate for sealant work, because every site is different. What we look at:
- The size and state of each joint
- Working within restricted access windows
- Travel to remote or island sites
- How much there is to seal
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Any specification or named product
- Access details, including height
- The postcode of the building
- Photos of the joints, close up and from further back
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. If you have questions first, give us a call on 01277 525 020 or email the details over.
What we are called out for in Colliston
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone.
Things that usually lead to an enquiry:
- Previous reseals run over old sealant
- Old perimeter mastic that has dried out
- Water coming in around window frames
- Sealant pulling away from frames or panels
When a college such as Dundee & Angus College - The Glebe, 2.4 miles to the south-east of Colliston, builds or refurbishes, the mastic package usually has to fit around students and staff.
What to look for in a quote
- How long is the guarantee, and what does it include?
- Their approach to joint depth and backing
- Health and safety accreditation such as CHAS
- Will RAMS and insurance details be available?
Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For work around Colliston, we aim for one trip, so photographs, sizes and a full list matter. External joints need a dry spell as well.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Let building users know which areas are affected
- Agree which areas must stay open
- Send asbestos survey details if the building is pre-2000
Getting a fixed quote
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email a schedule or drawings.

What else we do in Colliston
Leave it or put it right?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, saving a second set-up. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Resealing early avoids that.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Damaged frames that need replacing
- Movement beyond what any sealant can handle
- Providing access systems for the work
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think.
Joints and surfaces we work on
- Coping and flashing joints
- Cladding panel joints
- Shopfront frames
- Window and door perimeters
- Stone and brick facade joints
- Perimeter joints where frames meet the structure
Doing it in-house
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Some joints are best left to specialists: 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.
