Window Mastic in Firrhill
Mastic around window and door frames, sills and patio doors for homes and businesses in Firrhill and across Edinburgh. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Draughty joints inside around the window

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
How we handle window mastic in Firrhill
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Common call-outs are for draughts coming in around windows and doors and cracked sealant at the sill ends, across composite doors, patio & French doors and uPVC windows.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Firrhill, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Landlord and commercial work in Firrhill
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a few frames, or a day or more for a whole house. Parking in city streets around Firrhill can be tight or controlled, so it helps to know about permits or nearby bays. If you are in a flat, let us know how we get in at the street door.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

FAQs for Firrhill
Do you work for landlords with property near Slateford station?
Yes, rental work is part of what we do. You can email us at info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before work begins.
How do repairs to the shared parts of a tenement in Firrhill get organised?
The owners of the flats normally agree repairs to shared parts like the roof and outside walls, and many buildings have a factor to arrange it. Where the title deeds are silent, the Tenements (Scotland) Act 2004 fills the gaps. Windows often belong to the individual flat, but it’s worth checking your deeds.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do you come to Firrhill?
We do. Our applicators work in Firrhill, and the service is the same as everywhere else.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Do you work on first-floor windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
How the job changes by surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Window mastic in Firrhill: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Historic houses like Whitefoord House (about 3.5 miles north-east) are a reminder that the area around Firrhill has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Managing a site like Firrhill High School? Then the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Slateford station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as St Johns Colinton Mains Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- Rotten timber, which needs a joiner first
- Faulty window hardware
- Penetrating damp from a failed cavity tray or render

Joints and surfaces we work on
- Aluminium frames
- Patio & French doors
- Timber windows & doors
- Window sills
- Composite doors
- uPVC windows
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Doing several joints on one visit is usually more efficient than separate visits. We will give you a clear quote for the lot.
