Maryhill Window Mastic
Our applicators work in Maryhill on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Sealant in the wrong colour for the frame
- Cold air getting in at the frame edge
- Rushed sealant from a window installation
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before we start. It won’t solve:
- Draughts through the window seals rather than the frame
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Window sills
- Composite doors
- Patio & French doors
- uPVC windows
- Timber windows & doors
- Aluminium frames
Window mastic for homes and businesses in Maryhill
Homes in Maryhill have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you are dealing with draughts coming in around windows and doors and gaps left after new windows were fitted, we can help, whatever the surface.
Maryhill is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
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.

What else we do in Maryhill
Windows and doors in Maryhill
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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, often through a property factor. Windows usually belong to the flat, but the title deeds have the final say.
Tenement House, about 2.1 miles south-east, is one of the historic houses in the wider area around Maryhill, and older homes nearby need a sealant that suits their walls. Managing a site like Cleveden Secondary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Summerston station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Quotes for window mastic in Maryhill
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- How many rooms, windows or areas are involved
- The amount of work
- Whether old sealant or filler has to be cut out
- Whether the work is at height
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Whether it’s a home or a business
- Any previous sealing or DIY work
- Roughly how big the job is
- The address or postcode of the job

Different surfaces, different methods
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Make sure the drainage slots aren’t blocked
- Keep timber frames painted
- Do not aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just email us at info@mrmastic.co.uk.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Parking in city streets around Maryhill can be tight or controlled, so it helps to know about permits or nearby bays. For flats, mention the door entry system and any shared-stair arrangements.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

No, because it fails. We remove every bit of old sealant first.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
