Ashiestiel: your questions answered
Is Ashiestiel in your area for window mastic?
Yes. Our work covers the whole of Scotland, and Ashiestiel is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear quote.
Do you work for landlords with property near Galashiels station?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before work begins.
Do you work on first-floor windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we will confirm what’s needed.
How long does it take to reseal the windows on a house?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Can resealing stop a draught around my window?
If the draught is coming in around the frame, yes. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Window mastic in Ashiestiel
Around Ashiestiel we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have gaps between the frame and the inside reveal and untidy mastic left by window fitters, we can help, on composite doors, patio & French doors and uPVC windows alike.
In and around a place like Ashiestiel, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
How we quote for window mastic
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- Mould in or behind the old joints
- The number of rooms or windows
- Working hours on commercial sites
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- A few photos by email, if you can
- Any access issues, like height or stairs
- What’s wrong with the joints now
- If it’s domestic, commercial or a hotel
If you’re in Ashiestiel and need window mastic, email us at info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Windows and doors in Ashiestiel
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Historic houses like Peel House (about 0.3 miles south-east) are a reminder that the area around Ashiestiel has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Galashiels station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

When to call us in Ashiestiel
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Look out for these signs:
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
Historic houses such as Peel House, about 0.3 miles south-east, show how far back building around Ashiestiel goes, and older homes nearby need a sealant that suits their walls.

What we do, step by step
We keep the work tidy and contained to the joints we are treating. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we tell you how long to leave it before we go. Outdoor work around Ashiestiel depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules
- Move anything stored near the joints

Advice
Why act early in Ashiestiel
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and send you a clear quote before we start.
