About our window mastic in Wellbank
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. If you’re dealing with a bead that doesn’t match the frame and old mastic that has gone black or come away, we can put it right.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Your job is guaranteed for a year, as with all our work.

Signs you need window mastic in Wellbank
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The problems people normally mention when they call are:
- Gaps left after new windows were fitted
- Cracked or shrunken mastic around the frame
- Water coming in at the bottom corners of a door
- Gaps between the frame and the inside reveal
Letting a property close to Monifieth station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Windows and doors in Wellbank
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. 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.
Around Wellbank, as everywhere, window mastic is only as good as the preparation behind it.

Wellbank questions
Can you help a landlord with a rental near Monifieth station?
Yes, we work for landlords and letting agents. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Is Wellbank in your area for window mastic?
Yes, Wellbank is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Is the new sealant paintable?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.
How to look after the new joints
To keep the joints looking good and working properly:
- Clear any debris from frame drain holes
- Keep paint and stain on wooden frames in good order
- Ventilate rooms so frames don’t stay wet inside
- Check the mastic once a year
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.

Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking

We quote each job on its own, so the first step is telling us about yours. Just send an email to info@mrmastic.co.uk with the details, and pictures are welcome.
What we do, step by step
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a few frames, or a day or more for a whole house. For a place like Wellbank, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- Tell us if parking is tricky
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Wellbank
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
