Window mastic for homes and businesses in Dogslacks
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. Where the air is getting in through the window itself, we will say so. We work on uPVC windows, patio & French doors and timber windows & doors, and people most often call us about leaking joints at the ends of sills and rushed sealant from a window installation.
Mastic can only go onto a dry joint, so outside work in Dogslacks depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Whatever the size of the job, you get the same one-year guarantee.

Windows and doors in Dogslacks
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
In and around Dogslacks, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a few frames, or a day or more for a whole house. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in

Related advice
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Dogslacks, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.

FAQs for Dogslacks
Is there a guarantee on window mastic in Dogslacks?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you do window mastic in Dogslacks?
Yes, Dogslacks is within the area we cover. Our work covers the whole of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing.
Can tenants book the work?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
What does window mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk and let us know what needs doing and where.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints.
When it is not the sealant
New sealant can’t fix everything, and we will tell you before any work starts. It will not solve:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Penetrating damp from a failed cavity tray or render
- Rotten timber, which needs a joiner first
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

Landlords, agents and businesses in Dogslacks
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Keeping the joints in good condition
So the new joints stay in good condition:
- Wash the frames with mild soapy water
- Do not aim a pressure washer at the joints
- Check the mastic once a year
- Air rooms to keep condensation down around windows
Most silicone sealants won’t take paint, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
When to call us in Dogslacks
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That’s what backing rod is for.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
- Sealant in the wrong colour for the frame
If you live in an older home near Middlebie Parish Church And Churchyard, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
