What happens if it’s left?
Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. For buildings near Colgrain, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

How we handle mastic sealing in Colgrain
Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. Most enquiries involve draught complaints from residents or tenants and mastic failing across several blocks on an estate, across window and door perimeters on blocks, communal kitchens and washrooms and shopfronts below residential blocks. For commercial sealant work in Colgrain, you deal with one contact from quote to sign-off, whether it’s one building or several.
In smaller Scottish places like Colgrain, managed property is mostly small blocks, sheltered housing, hotels and community buildings. Frames on exposed elevations are where mastic usually fails first.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Common questions from Colgrain clients
Does the sea air around Colgrain change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Is Colgrain off your patch?
Not at all. Colgrain is within our area. Every Scottish council area is within our area. Where we can, we group nearby jobs to make the most of each trip.
How do you reach windows on upper floors?
Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place, and we will tell you how we’d approach it.
How do I request a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send photos by email. Include photos or drawings if you have them.
Will you quote for a small job?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
How much does the work cost?
We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.
Do you need to see the site first?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Commercial and mixed-use buildings
Commercial buildings have mastic at shopfronts, entrances and external joints. We work across portfolios on a planned basis.
Mastic sealing around Colgrain: points for this area
Colgrain is within about 1 mile of the coast. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, and they deserve more regular inspection. Colgrain is in the west of Scotland, the wetter side of the country. The weather side of a block typically needs attention first. Programmes allow for wet days.
For a school such as Hermitage Academy, perimeter mastic on windows and doors is a holiday job. Buildings close to stations like Craigendoran station (to the north-west of Colgrain) are often flats over shops, with frame mastic to keep sound.
Colgrain is about 2 miles south-east of Helensburgh, in Argyll and Bute. Across the G82 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Argyll and Bute, 124 places are covered, including Colgrain. We also cover Glasgow, around 18 miles from Colgrain.
Business premises anywhere in G82 and G84 are within our area for mastic joints.

Around Colgrain
The closest station to Colgrain is Craigendoran station, roughly 1.2 miles north-west of the centre. A little further out are Kilmahew Castle (1.9 miles south-east) and Oak Mall (3.8 miles south-west). The countryside around Colgrain includes Lyle Hill.
Looking after the joints
Regular inspection catches problems early. In particular:
- Log resealing dates block by block
- Share your contractor requirements early
- Protect low-level joints in entrances
- Check sealant joints during planned building inspections
Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over unless told otherwise.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
When to call us in Colgrain
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Clients typically get in touch after noticing something like this:
- Worn sealant at communal door frames
- Occupiers reporting cold air round windows
- Cracked, hardened mastic round windows on a block
- Leaks at window and door perimeters
Older buildings near Colgrain, from historic houses such as Hill House, 2.7 miles north-west of Colgrain, to more modest stock, need compatible products when frames are resealed.
