Window mastic for homes and businesses in Bieldside
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for cracked or shrunken mastic around the frame and gaps left after new windows were fitted, across composite doors, timber windows & doors and patio & French doors.
Sash and case windows are a feature of older tenements in all four Scottish cities, and plenty still have them. Whether you’re in a tenement flat or a house in Bieldside, the joint between frame and wall is what keeps the weather out.
We stand behind the work with a one-year guarantee.

Your questions about window mastic in Bieldside
Do you cover Bieldside for window mastic?
Yes, Bieldside is within the area we cover. We work across all of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
How do repairs to the shared parts of a tenement in Bieldside 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.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then email us at info@mrmastic.co.uk.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
What affects the quote in Bieldside
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Any mould that needs treating
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
Asking for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- Roughly how big the job is
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Describe the problem, the location and the size of the job. When it suits you, send an email to info@mrmastic.co.uk.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
If you are 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.
Why it’s worth doing now in Bieldside
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we will tell you. In a tenement flat in Bieldside, a failed seal is rarely just your problem: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
What you pay reflects the work, not guesswork. That is why we ask about the job first and give you a clear quote before we start.

Windows and doors in Bieldside
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. 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 usually belong to the flat, but the title deeds have the final say.
Schools such as Cults Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Cults West Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are and we leave things clean and tidy. Parking in city streets around Bieldside 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.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

Signs you need window mastic in Bieldside
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. Backing rod sets the right depth.
Look out for any of the following:
- Draughty joints inside around the window
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
- Gaps left after new windows were fitted
For landlords with property near Aberdeen station, renewing tired window mastic between tenants heads off draught and damp complaints.

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
