Window & door mastic in Crosshill, Glasgow
Mastic around window and door frames, sills and patio doors for homes and businesses in Crosshill and across Glasgow. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
- Mastic that has split away from the wall
Signs you need window mastic in Crosshill
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
Signs it’s time to call us include:
- Gaps where the sill meets the wall
- Gaps left after new windows were fitted
- A bead that doesn’t match the frame
- Damp patches on the reveal after heavy rain
For landlords with property near Crosshill station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Window mastic for homes and businesses in Crosshill
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We are often asked to deal with a bead that doesn’t match the frame and gaps left after new windows were fitted, across composite doors, aluminium frames and timber windows & doors.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, and plenty still have them. Whether you are in a tenement flat or a house in Crosshill, the joint between frame and wall is what keeps the weather out.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What else we do in Crosshill
How we quote for window mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, email us at info@mrmastic.co.uk and we’ll give you an honest view and a quote.
What to tell us for a quote
Photos by email are helpful but not essential. Please mention:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Where the property is
- Access, such as stairs, a lift or height
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved.
DIY sealant or a professional job?
Too much sealant is as bad as too little. 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 is fine. We remove it and do the joint properly, so just mention it when you contact us.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep jet washers away from the mastic
- Clear any debris from frame drain holes
- Repaint timber before it’s bare
- Look round the frames every year or so
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours for a handful of frames, longer for a whole house, depending on how much there is to do. In a city area like Crosshill, 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.
- 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.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on

Crosshill: your questions answered
Who arranges sealant work on the shared parts of a tenement in Crosshill?
Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not, and we can quote for the factor or the owners directly.
Can you help a landlord with a rental near Crosshill station?
Yes. We work for landlords and agents as well as householders. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Does the work come with a guarantee?
Yes. Every job comes with our 12-month guarantee, and we’re ARBOMaster approved applicators.
Will new mastic stop draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do you have sealant for grey or black windows?
Generally, yes. Tell us the frame colour when you get in touch and we will match it as closely as we can.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you come to Crosshill?
Yes. From our base in Crawley, we cover South East England, London and all of Scotland, Crosshill included.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
- A sash or casement that won’t close properly
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
Joints and surfaces we work on
- Timber windows & doors
- Composite doors
- uPVC windows
- Aluminium frames
- Patio & French doors
- Window sills
What happens if it’s left?
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Private landlords in Crosshill 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.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk.

Crosshill homes and the weather
The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Windows generally belong to the flat, but the title deeds have the final say.
Provand's Lordship, about 2.2 miles north-east, is one of the historic houses in the wider area around Crosshill. For site and facilities teams at buildings such as Holyrood Secondary School, its window and door frames need their mastic kept sound, just like a home’s.
