Construction mastic for Oban sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Construction mastic in Oban, done properly
On a new build, the mastic package is one of the last trades through each area. Mastic Doctor takes on mastic packages for main contractors and developers. The enquiries we see most involve sealant knocked or painted over by other trades and missed perimeter joints on a new elevation, across brick and block movement joints, cladding and panel joints and sanitary and kitchen joints. A single leaking joint is often how a building in Oban first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
External sealing around Oban depends on dry faces and the right temperature. We build some give into the plan and agree it with the site manager.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Quoting for work in Oban
The price varies from site to site. It mainly depends on:
- Travel to remote or island sites
- Backing rod, priming and other preparation
- How much there is to seal
- The product specified
A quote for mastic packages depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
What we need to price the job
Good information means a firmer quote. When you get in touch, include:
- The product your specification calls for
- Whether the building will be occupied during the work
- Anything awkward about access or site hours
- Whether an asbestos survey exists
The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.
What else we do in Oban
What sealant work can’t fix
Being straight saves everyone time. New sealant won’t cure:
- Rework caused by others damaging completed areas
- Deciding which fire-stopping product a penetration needs
- Designing joint widths or choosing the specification (that sits with the designer)
If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
Where we work in Oban

Questions we are asked in Oban
Can being near the sea in Oban affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Is Oban too small for you to travel to?
No. Places such as Oban are covered as much as the big towns. We work across every Scottish council area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you work to our specification?
We follow the specified sealant. Specifications often reference BS EN 15651 or BS 6213.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Can you work while the building is occupied?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Can weather delay the job?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
How long before the joints can be used?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.
Signs you need construction mastic in Oban
A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture, which opens up internal joints, particularly where caulk has been used in a joint that moves. Picking a flexible sealant where there’s movement keeps snags down.
Any of the following is a good reason to get the joints checked over:
- Old sealant on a refurbishment that needs stripping before new work
- Perimeter gaps outside the sealant’s range
- Cracks opening in caulked internal joints
- Sanitary sealant damaged by following trades
When a school such as Oban High School is extended or refurbished, the mastic package is often squeezed into the holidays.
What your quote should include
- Whether old or failed sealant will be cut out, not overlaid
- Their pre-qualification and accreditations
- Is the sealant right for the movement and the substrate?
- Who will actually carry out the work
Diagnose, treat, sign off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. For work around Oban, we aim for one trip, so photos, sizes and a full list matter. External joints need a dry spell as well.
- First we look at the scope on site or from drawings.
- A fixed quote sets out scope, products and phasing.
- Paperwork is agreed and applicators are inducted on site.
- Sealing follows the programme as areas are released.
- Any frame gaps or issues outside our scope are flagged to the site team.
- The package is closed out, snags cleared and backed by our 12-month guarantee.
Preparing the site
- Move anything stored against the joints
- Send your site hours and access windows
- Send asbestos survey details if the building is pre-2000
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Surface by surface
Window and door perimeters
Perimeter joints between frames and the structure are the weather line on any new building. We use the specified perimeter sealant, usually a low-modulus neutral-cure silicone and set the depth with backing where needed.
Internal decorators’ caulk
Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s paintable and suits gaps that don’t move while moving joints need a flexible sealant.
New build and refits around Oban
With the shore within about 1 mile, Oban counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Oban is on Scotland’s wetter western side. We keep internal mastic in hand so wet days aren’t lost.
Hotel extensions and refits, at places such as The Ranald Hotel (less than half a mile north of Oban), usually run between busy periods, so the sealing is squeezed into short windows. New wings at hospitals like Lorn and Islands Hospital (0.7 miles south of Oban) bring long runs of window and panel joints to seal.

Anyone looking for construction mastic in PA34 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. We cover commercial and managed buildings on Market Street, High Street and Argyll Square and the roads nearby. Being close to the A85 and A816, Oban is easy to get to with materials and equipment. We also cover Dunollie (1 mile north), Ganavan (2 miles north), Dunbeg (3 miles north), Kilmore (3 miles south-east) and Connel (4 miles north-east) for mastic packages. Oban is one of the busier places in Argyll and Bute, and its commercial and public buildings are all within our area. Remote and island addresses take more planning, from travel and ferries to the weather, so mention the location when you phone 01277 525 020 or email drawings and photos.
