What sealant work cannot fix

- Penetrating damp from a failed cavity tray or render

Window mastic in Clermiston, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. Common call-outs are for whistling draughts around closed windows and cracked or shrunken mastic around the frame, across window sills, aluminium frames and timber windows & doors.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. Access is the first thing to plan for a job in Clermiston.
Each job carries a 12-month guarantee, whatever its size.

Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Common questions in Clermiston
Who arranges sealant work on the shared parts of a tenement in Clermiston?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not, and we can quote for the factor or the owners directly.
Do you work for landlords with property near South Gyle station?
Yes, we work for landlords and agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Can you do several jobs on one visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
How do I get a quote for window mastic in Clermiston?
Every job is different, so each one gets its own quote. To get one, email us at info@mrmastic.co.uk with a short description of the job.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
What happens on the day
On the day, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take most of a day for a typical house, less for a few frames. For a tenement in Clermiston, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts

Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Why it’s worth doing now in Clermiston
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. Wind-driven rain gets into any failed joint on the outside of a city building, and in Clermiston, damp can spread through stone and plaster before anyone sees it.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before we start.
Why book with us

What affects the quote in Clermiston
There’s no set price list, because jobs vary so much. The quote depends on:
- The type of sealant required
- Whether the work is at height
- Mould in or behind the old joints
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- How we’d reach the joints
- Any previous sealing or DIY work
- Pictures of the joints, sent by email
- Whether it’s a home or a business

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Check the mastic once a year
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
- Make sure the drainage slots are not blocked
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Windows and doors in Clermiston
Clermiston is close to 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 window and door frames, especially on the side facing the sea. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Windows normally belong to the flat, but the title deeds have the final say.
Historic houses such as Caroline Park, about 2.7 miles north-east, show how far back building around Clermiston goes. Managing a site like Craigmount High School? Then the mastic around its windows and doors needs looking after like any other building’s. Rented homes near South Gyle station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
