Common problems we fix in Powderhall
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
If you can see any of these, it’s time to have the joints looked at:
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
If you live in an older home near St Philip's Church And Hall, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Which colour the sealant will be
- The length of the guarantee
- When the joint can take water or movement
- Is the old sealant removed completely?
How we handle sand mastic in Powderhall
Across Powderhall, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We’re often asked to deal with crumbling sand mastic round a window and mastic that needs renewing before redecorating, across period & listed homes, timber door frames and stone surrounds.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. In Powderhall, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Windows and doors in Powderhall
Powderhall is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Whitefoord House (about 1.2 miles south-east) nearby, there’s older building stock in the area around Powderhall as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Edinburgh Waverley station? Then any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as Drummond Community High School, its window and door frames need their mastic kept sound, just like a home’s.

Your questions about sand mastic in Powderhall
I let a flat near Edinburgh Waverley station. Can you help?
Yes, we work for landlords and letting agents. 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.
Does the coastal weather in Powderhall affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. The silicone is cut out and the joint cleaned, then point it with sand mastic.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Can I choose the sealant colour?
We help you choose a colour that suits. The choice depends on the product the joint needs.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
What does sand mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Do you have insurance?
Yes. We’re fully insured.
Keeping the joints in good condition
Aftercare is simple:
- Get any rot dealt with first
- Clear gutters so water does not pour onto the windows
- Ask us before painting near the mastic
- Check the mastic when you check the paintwork
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why it’s worth doing now in Powderhall
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a tenement flat in Powderhall, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
Why book with us
- More than 20 years in sealant work
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas
- Tidy, careful work

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 the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What happens on the day
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. For a tenement in Powderhall, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. It helps to know which it is when you get in touch.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Tell us about any water getting in
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
