Window mastic in Colinton Mains
From a single sill to a whole house of windows, the work is priced before anything is done. Just send an email to info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. Common call-outs are for gaps where the sill meets the wall and rushed sealant from a window installation, on window sills, timber windows & doors and aluminium frames.
In a Scottish city, many flats have windows two, three or four floors up, where failing mastic is easy to miss. For a flat in Colinton Mains, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

What the job involves on each surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
If you’re 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 doesn’t work out, we can still put it right.
Colinton Mains homes and the weather
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 generally belong to the flat, but the title deeds have the final say. Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. If a home is listed or in a conservation area, it’s worth checking with the council before changing the look of windows or walls.
If you live in an older home near St Johns Colinton Mains Church, the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Firrhill High School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Slateford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- The old material and how stubborn it is
- The product the joint needs
- How much there is to do
- How easy the joints are to reach
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- The type of property
- Any previous sealing or DIY work
- Where the job is, and your postcode
- The rough size of the job
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Use gentle cleaners on frames and sealant
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
FAQs for Colinton Mains
How do repairs to the shared parts of a tenement in Colinton Mains get organised?
Shared parts of a tenement, such as the roof and outside walls, are usually repaired with the agreement of the owners, often through a property factor. 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 Slateford station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Should I try DIY first?
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.
Are you insured?
Yes. We are fully insured.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses.

How it works
All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a few hours for a few frames, or a day or more for a whole house. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Colinton Mains, 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.
- We remove the old mastic and clean the frame edge and wall.
- 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.
Preparing for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
