Window mastic in Ganavan, done properly
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we’ll say so. If you have hard, cracked sealant around windows and cracked internal joints between frame and plaster, we can help.
Outdoor sealant needs a dry surface, so window work around Ganavan is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Ganavan: your questions answered
Do you cover smaller places like Ganavan?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Oban station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
How long does it take to reseal the windows on a house?
Allow most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Honest limits
In fairness, there are a few things sealant won’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
- A sash or casement that won’t close properly
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It usually takes most of a day for a typical house, less for a few frames. Around Ganavan, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.

How to look after the new joints
So the new joints stay in good condition:
- Don’t paint over the silicone
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
- Look round the frames every year or so
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
What window mastic looks like in Ganavan
Ganavan is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
Schools such as Oban High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Oban station, renewing tired window mastic between tenants heads off draught and damp complaints.

Quotes for window mastic in Ganavan
We do not publish a price list, because jobs vary so much. What we look at:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- Any working-time requirements on site
- How many areas need sealing
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Helping us quote
Before you ask for a quote, have a think about:
- Photos by email, if that’s easy
- The address or postcode of the job
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
We quote each job on its own. Just email us at info@mrmastic.co.uk with the details.
Why it’s worth doing now in Ganavan
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. In a place like Ganavan, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
