What window mastic looks like in Colinton
Edinburgh’s Old and New Towns are a UNESCO World Heritage Site, with sash windows throughout the Georgian New Town. 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
For site and facilities teams at buildings such as Army School of Bagpipe Music and Highland Drumming, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Kingsknowe station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Colinton is about 3 miles south-west of Edinburgh, in Edinburgh. Our applicators cover window mastic for homeowners, landlords and businesses in Colinton and nearby. Colinton is one of 175 towns and villages in Edinburgh where we work for window mastic.

How we handle window mastic in Colinton
From a single sill to a whole house of windows, you’ll get a clear quote before any work starts. Just drop us a line at info@mrmastic.co.uk and tell us how many frames there are and how they’re reached. Common call-outs are for rushed sealant from a window installation and mastic that’s falling out in pieces, across composite doors, window sills and timber windows & doors.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Natural stone around older windows needs a sealant that won’t mark or attack it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

How it works
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a handful of frames, longer for a whole house. In a city area like Colinton, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.
- 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work

Advice
Common questions in Colinton
Who arranges sealant work on the shared parts of a tenement in Colinton?
Most tenements arrange shared repairs through the owners or a property factor. 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.
Can you do window mastic in Colinton?
Yes. Our work covers the whole of Scotland, and Colinton is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Colinton.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Are you fully insured?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Can I paint over the new sealant?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
What we can’t put right
A few problems are outside what sealant work can do:
- A frame that has rotted at the joint
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Private landlords in Colinton must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Common problems we fix in Colinton
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Look out for these signs:
- Mastic that’s falling out in pieces
- Untidy mastic left by window fitters
- A bead that doesn’t match the frame
- Leaking joints at the ends of sills
For an older house near a landmark such as Colinton Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the mastic once a year
- Repaint timber before it’s bare
- Keep paint off silicone joints
- Ventilate rooms so frames don’t stay wet inside
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
