Window mastic in Fountainhall
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on aluminium frames, window sills and patio & French doors, and people most often call us about cold air getting in at the frame edge and rain getting in at the frame or under the sill.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
Whatever the size of the job, you get the same 12-month guarantee in Fountainhall and across the Scottish Borders.

What we can’t put right
In fairness, some problems need a different trade:
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame

Window mastic in Fountainhall: 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. 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 Fountainhall, as everywhere, window mastic is only as good as the preparation behind it.

Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we’ll tell you. 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.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

FAQs for Fountainhall
Do you work for landlords with property near Stow station?
Yes, rental work is part of what we do. 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 we start.
Do you cover Fountainhall for window mastic?
Yes, Fountainhall is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
How long will my window job take?
A handful of frames is a short visit, while a whole house takes longer. You will get a timescale with the quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can be quoted together.
What we do, step by step
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. Outdoor work around Fountainhall depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Preparing for the visit
- Mention any tricky access
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

Related advice
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep solvents and bleach off the sealant
- Don’t paint over the silicone
- Walk round the house once a year and look at the joints
- Use gentle cleaners on frames and sealant
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Do you need window mastic in Fountainhall?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
The problems people generally mention when they call are:
- Mastic that has split away from the wall
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
- A bead that doesn’t match the frame
Letting a property close to Stow station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
