About our window mastic in Braeside
Homes in Braeside have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We’re often asked to deal with untidy mastic left by window fitters and damp patches on the reveal after heavy rain, on patio & French doors, timber windows & doors and aluminium frames.
Braeside is in one of Scotland’s four big cities, where many older buildings are sandstone or granite. Natural stone around older windows needs a sealant that will not mark or attack it, so acetoxy silicones, which can attack some stone, are best avoided.
Every job is covered by a 12-month guarantee.

Why deal with it now?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. For landlords in Braeside, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
- Faulty window hardware
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.

Braeside questions
Can you help a landlord with a rental near Aberdeen station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we will give you a fixed price before any work starts.
Does the coastal weather in Braeside affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
What information do you need?
A short description and the location, with pictures by email if possible. If we need more, we will ask.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Do you come to Braeside?
Yes, we do. Braeside is part of the area we cover.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Do you have sealant for grey or black windows?
Usually, yes. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
What happens on the day
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes anything from an hour or two to a full day, depending on how many frames there are, including the tidy-up. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Braeside, it helps to know the floor, the door entry arrangements and the nearest parking.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Mention if the joints have been sealed before
- Clear the area around the work
- Tell us about access, such as stairs, a lift or high-level joints

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Do not aim a pressure washer at the joints
- Make sure the drainage slots are not blocked
- Keep paint off silicone joints
- Check the mastic once a year
Most silicone sealants won’t take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Leaks normally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Different surfaces, different methods
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.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
Frames and glazing around Braeside
Braeside is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.
In the older streets around Mannofield Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Airyhall Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Aberdeen station, renewing tired window mastic between tenants heads off draught and damp complaints.
