Bieldside Sand Mastic
Our applicators work in Bieldside on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly.

Sand mastic in Bieldside, done properly
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. If you are dealing with modern sealant on a period surround and cracked mastic round a front door frame, we can help, whatever the surface.
In a Scottish city, many flats have windows two, three or four floors up, so the mastic outside can go unchecked for years. For a flat in Bieldside, access is the first thing to plan, and in a tenement the outside of the building may be a shared repair.
Every job comes with our one-year guarantee.

What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a single window, longer for several. For a tenement in Bieldside, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property

Bieldside questions
Do you work for landlords with property near Aberdeen station?
Yes, we work for letting agents and landlords. 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 we start.
Is Bieldside in your area for sand mastic?
Yes. We work across all of Scotland, and Bieldside is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Which is right for my windows, sand mastic or modern sealant?
Sand mastic usually suits period timber windows best. Modern frames normally suit a flexible sealant.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. All the old silicone is removed first so the mastic beds in well.
Can I choose the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
How long does sand mastic take?
Typically it takes a few hours for a single window, longer for several. Larger jobs naturally take longer, and we will tell you how long to expect.
Landlords, agents and businesses in Bieldside
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can be quoted together.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
DIY sealant or a professional job?
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.
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.
What happens if it’s left?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry so renewing it early protects the window. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk and we will talk you through it.

Sand mastic in Bieldside: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.
For landlords with property near Aberdeen station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Cults West Parish Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Cults Academy, larger buildings have plenty of frames, and the mastic around each one ages.
