Silverknowes Window Mastic
Problem with your window and door frames in Silverknowes? We cut out the old, prepare the joints and apply the right sealant.
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
- Rushed sealant from a window installation
Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Private landlords in Silverknowes must meet the Repairing Standard, and damp or leaks can fall short of it, so failed sealant is best replaced before it becomes a complaint.
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.

How we handle window mastic in Silverknowes
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We work on composite doors, timber windows & doors and patio & French doors, and the jobs we see most are rain getting in at the frame or under the sill and gaps left after new windows were fitted.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. In Silverknowes, as anywhere, the mastic between frame and wall is what stops draughts and rain getting in.
You get a one-year guarantee, the same in Silverknowes as everywhere else we work.

Silverknowes: your questions answered
How is work on the outside of a tenement in Silverknowes normally arranged?
The owners of the flats usually agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. The Tenements (Scotland) Act 2004 sets out how that works where the title deeds do not. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can you help a landlord with a rental near South Gyle station?
Yes. We work for letting agents and landlords as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply send an email to info@mrmastic.co.uk.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Do you cover Silverknowes?

What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.

What else we do in Silverknowes
The process
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Silverknowes, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- 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.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

Advice
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think before you book.
Surfaces we seal
- Patio & French doors
- uPVC windows
- Composite doors
- Aluminium frames
- Window sills
- Timber windows & doors
Surface by surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
When to call us in Silverknowes
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, while a joint packed solid can’t stretch. Backing rod sets the right depth.
The most common problems we see are:
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
Letting a property close to South Gyle station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep timber frames painted
- Look round the frames every year or so
- Keep paint off silicone joints
- Keep solvents and bleach off the sealant
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Silverknowes homes and the weather
Silverknowes is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Managing a site like Craigroyston Community High School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Columba's Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
