About our window mastic in Altens
Homes in Altens have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include gaps where the sill meets the wall and rushed sealant from a window installation, on uPVC windows, composite doors and window sills.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Stone needs a sealant that suits it, which usually means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Our work is backed for twelve months, in Altens and everywhere else we cover.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes most of a day for a typical house, less for a few frames. In a city area like Altens, 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 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.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can

Advice
How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- How much old sealant there is and how hard it is to remove
- The amount of work
- Any mould that needs treating
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- Photos by email, if that is easy
- How we’d reach the joints
- Any previous sealing or DIY work
To get a quote, email us at info@mrmastic.co.uk with the location and a short description of the problem. We will send you a clear quote before any work starts.
What we are called out for in Altens
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Any of these means the joints need attention:
- Old mastic that has gone black or come away
- White mastic on grey or black frames
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
For landlords with property near Aberdeen station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before booking
- What guarantee comes with the work
- Is the old sealant removed completely?
- Which colour the sealant will be
- Who does the work, and how experienced they are
Other services in Altens
What the job involves on each surface
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.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Altens homes and the weather
Altens is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Friendville (about 2.4 miles north-west) are a reminder that the area around Altens has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Nigg Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Lochside Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

When it is not the sealant

Altens questions
How do repairs to the shared parts of a tenement in Altens get organised?
It generally goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds do not.
Can you help a landlord with a rental near Aberdeen station?
Yes. We work for landlords and letting agents as well as householders. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Do you work in Altens?
Yes. We work in Altens. For a quote, send an email to info@mrmastic.co.uk.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
How many windows can you do in a day?
Allow most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Paint up to the joint, not over it
- Use gentle cleaners on frames and sealant
- Clear any debris from frame drain holes
- Avoid harsh chemicals near the mastic
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
