Mastic sealing for Kilmun sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
On site: what to expect
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself normally taking a day or two for a single block, longer for an estate programme. Travel to smaller Scottish places like Kilmun is planned so the job is finished in one visit where possible, so photos, sizes and a full list matter. External joints need a dry spell as well.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- Have the specification and drawings to hand
- Make sure the joints can be reached
- Let us know about inductions and permits
Getting a fixed quote
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email drawings and photos.

Mastic sealing in Kilmun: the local picture
Kilmun is within about 1 mile of the coast. On buildings near the shore, the side facing the weather normally needs its mastic renewed first; plan inspections around that. Kilmun is on Scotland’s wetter western side. The most exposed elevations need checking most often. We plan block programmes with the forecast in mind.
Schools and community buildings such as Dunoon Grammar School need frame and external mastic kept sound like any building.
Kilmun is about 7 miles north-west of Greenock, in Argyll and Bute. We cover Kilmun, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Kilmun is one of 124 places in Argyll and Bute on our list. Sites around Glasgow have their own page, roughly 28 miles from Kilmun.

Leave it or put it right?
A bead run over old mastic can look like a repair. It doesn’t bond and usually fails within a short time. Cutting out and resealing properly does it once. In Scotland, wind-driven rain finds a failed joint quickly, so it’s worth renewing joints around Kilmun before they leak.
Pricing mastic joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What we’re called out for in Kilmun
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.
Things that typically lead to an enquiry:
- Estate-wide sealant that is simply worn out
- Water getting in round frames after rain
- Occupiers reporting cold air round windows
- No planned programme for sealant
Older community buildings, St Munn's Parish Church among them, often have frames of mixed ages whose mastic varies.
Comparing quotes
- Whether old or failed sealant will be cut out, not overlaid
- Health and safety accreditation such as CHAS
- The terms of the workmanship guarantee
- How the joint faces will be prepared and primed
Doing it in-house
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Kilmun: questions and answers
Does the sea air around Kilmun change the choice of sealant?
It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Can you quote for mastic across several buildings in and around Kilmun?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we will give a fixed quote.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. If any flats or units need access, we’ll tell you in advance so you can arrange it with occupiers.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
