How we handle mastic sealing in Colmonell
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We will confirm the colours available for the specified product. The enquiries we see most involve cracked, hardened mastic round windows on a block and worn sealant at communal door frames, across communal kitchens and washrooms, window and door perimeters on blocks and shopfronts below residential blocks. Searching for sealant specialists in Colmonell? Mastic Doctor has worked for contractors, FMs and building owners since 2005.
In smaller Scottish places like Colmonell, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic typically fails first.
A 12-month guarantee applies to all our work. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we will arrange a return visit.

What the job involves on each surface
External movement joints
Brickwork, blockwork and panel joints let a building move. Once that sealant goes, rain can reach the wall.
Communal areas
Entrance doors, screens and corridor junctions in communal areas all have sealant joints. Fresh joints make shared areas look looked after.

Frames, entrances and external joints in Colmonell
Colmonell sits close to the coast, within about 3 miles. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. The west of Scotland, where Colmonell is, gets more rain than the east. The most exposed elevations need checking most often. Programmes allow for wet days.
Wherever your building is in or near Colmonell, we look at the whole elevation before quoting, so you know what needs doing now. Around Colmonell, a planned programme renews failed mastic across a building or estate in one go.

Common questions from Colmonell clients
Is Colmonell too small for you to travel to?
No. Places such as Colmonell are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Good photographs up front let us bring everything on the first visit.
Can you quote for mastic across several buildings in and around Colmonell?
Yes. Planned programmes across a building, block or estate are a core part of this service. Residents are given notice through you, and the work moves building by building.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Is mastic sealing guaranteed?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. Buildings are scheduled in turn with dates agreed in advance.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
For managing agents and facilities managers
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Colmonell can sit alongside others in a wider programme across South Ayrshire.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.
On site: what to expect
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking a few days for most blocks, with larger programmes scheduled building by building. Travel to smaller Scottish places like Colmonell is planned so the job is finished in one visit where possible, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- First comes a look at the joints and, for older buildings, the asbestos records.
- A fixed quote covers the joints, products and order of work.
- We strip out the old sealant.
- The joints are prepared and resealed with the right product.
- We finish each building before moving to the next.
Preparing the site
- Flag any permit to work we will need
- Send your site hours and access windows
- Make sure the joints can be reached

Should maintenance staff do it?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
How the quote is worked out
Quotes vary with the job. Expect it to depend on:
- Travel to remote or island sites
- Joint width, depth and condition
- The total length or number of joints
- Site requirements such as inductions and permits
Pricing mastic joints depends on quantities, condition and access. Call for a quote.
What we need to price the job
Good information means a firmer quote. Helpful details to send:
- Drawings or a marked-up plan, if available
- Asbestos survey details if the building is older
- Anything awkward about access or site hours
- When you need the work done
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email the details over.
