Window Mastic in New Aberdeen
Window mastic across New Aberdeen and nearby, with old sealant always removed completely.
- Whistling draughts around closed windows
- A bead that does not match the frame
- Mastic that’s falling out in pieces
What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Wind-driven rain gets into any failed joint on the outside of a city building, and in a tall building in New Aberdeen, damp can travel a long way before it shows.
Doing several joints on one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

Window mastic for homes and businesses in New Aberdeen
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on window sills, uPVC windows and composite doors, and the jobs we see most are old mastic that has gone black or come away and cracked or shrunken mastic around the frame.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Stone needs a sealant that suits it, which normally means a neutral-cure product or a traditional sand mastic rather than an acetoxy silicone.
Whatever the size of the job, it’s backed by our one-year guarantee in New Aberdeen and across Aberdeen.

Window mastic in New Aberdeen: local notes
New Aberdeen is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. 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, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds.
Managing a site like Robert Gordon's College? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Peter's RC Church and Presbytery, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
New Aberdeen is about 1 mile east of Aberdeen, in Aberdeen. New Aberdeen gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Our Aberdeen coverage runs to 63 places, New Aberdeen among them.

What affects the cost of window mastic
You will get a clear quote before work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- Access and height
- Any mould that needs treating
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. For a job in New Aberdeen, tell us the floor, how the door entry system works and where we can park nearby.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
Questions from New Aberdeen
I let a flat near Aberdeen station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
How do repairs to the shared parts of a tenement in New Aberdeen 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 don’t, and we can quote for the factor or the owners directly.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status.
Can I paint over the new sealant?
It depends on the sealant. Some hybrid sealants can be painted; silicone cannot. Tell us if you are decorating and we will choose accordingly.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Should I try DIY first?
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.
Do you work on first-floor windows?
Usually, yes. Access is planned before any work starts, so mention the height and anything in the way.
How do I get a quote for window mastic in New Aberdeen?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
What we’re called out for in New Aberdeen
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.
The most common problems we see are:
- Mastic that is falling out in pieces
- Rushed sealant from a window installation
- Damp patches on the reveal after heavy rain
- Hard, cracked sealant around windows
For landlords with property near Aberdeen station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Comparing quotes
- How much experience the applicator has
- What product goes in the joint
- Whether all the old sealant comes out first
- What the cure time is
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
What else we do in New Aberdeen
When it is not the sealant
Some problems need a builder, plumber or other trade rather than us:
- Soft or decayed wood in the frame
- Worn gaskets, brush seals or a door that has dropped
- Broken hinges, locks or handles
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
