What affects the quote in Glenlomond
Every job gets its own quote. This is what makes a difference:
- The type of sealant required
- When we can work, for business premises
- The number and length of the joints
- The old material and how stubborn it is
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.
What to tell us for a quote
Before you ask for a quote, have a think about:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- The rough size of the job
- Pictures of the joints, sent by email
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job.
How we handle window mastic in Glenlomond
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on composite doors, patio & French doors and window sills, and common reasons people get in touch are old mastic that has gone black or come away and sealant in the wrong colour for the frame.
Mastic can only go onto a dry joint, so outside work in Glenlomond depends on the weather. Let us know about access to every frame, including any upstairs.
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.

Surface by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Glenlomond: your questions answered
What guarantee comes with window mastic in Glenlomond?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Is Glenlomond in your area for window mastic?
Yes. We work across all of Scotland, and Glenlomond is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Where are you based?
Our base is Crawley. We work across South East England, London and Scotland.
Do you work on first-floor windows?
Yes, in most cases. We plan safe access before the job.
DIY sealant or a professional job?
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.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Honest limits
To be straight with you, some problems need a different trade:
- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
What we seal
- Window sills
- Timber windows & doors
- Composite doors
- uPVC windows

What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, the area is protected and the work begins.

Related advice
Window mastic in Glenlomond: local notes
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Around Glenlomond, as everywhere, window mastic is only as good as the preparation behind it. In the older streets around Easter Balgedie church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Glenlomond
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
