About our sand mastic in Dalmally
Silicone on a period window often looks wrong and does not suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. If you’re dealing with weathered mastic on the most exposed windows and tired mastic found when preparing windows for paint, we can help, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
All our work comes with a 12-month guarantee, wherever you are in Argyll and Bute.

FAQs for Dalmally
Is Dalmally in your area for sand mastic?
Yes, Dalmally is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Do you work for landlords with property near Dalmally station?
Yes. We work for landlords and letting agents as well as homeowners. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Leave it or put it right?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. In an older home around Dalmally, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Why us?
- Approved under the ARBOMaster scheme

What affects the quote in Dalmally
We quote each job individually. These are the things that affect it:
- When we can work, for business premises
- Access and height
- The amount of work
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- A few pictures by email, if you can
- Roughly how big the job is
- Access, such as stairs, a lift or height
- Whether it has been sealed before
There’s no standard price list, because every job is different. Instead, we give you a clear quote for your job. To get started, send an email to info@mrmastic.co.uk.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Have rotten timber repaired before new mastic goes in
- Look over the window mastic once a year
- Keep modern sealant off the mastic
- Ask us before painting near the mastic
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured for the work.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What we are called out for in Dalmally
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
Signs it’s time to call us include:
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps between timber frames and stone or brick
- Cement or filler used on old window joints that has cracked
- Cracked mastic round a front door frame
If you live in an older home near Glenorchy Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- What the quote includes, VAT included or not
- The length of the guarantee
How the visit works
At the end, we look at the finished work together. The work normally takes a few hours per window, depending on the condition of the joints, depending on how much there is to do.

- Each surround is checked first.

Windows and doors in Dalmally
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
If you let a flat or house near Dalmally station, older sash windows in a rental need their mastic kept sound to keep the weather out.
