Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How we handle window mastic in Riverside of Blairs
Homes in Riverside of Blairs have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on composite doors, aluminium frames and window sills, and people most often call us about whistling draughts around closed windows and black, perished sealant on frames.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All our work is covered by our one-year guarantee, wherever you are in Aberdeen.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- How many rooms, windows or areas are involved
- The product the joint needs
- Any mould that needs treating
Doing several joints on one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.
Helping us quote
Before you ask for a quote, have a think about:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- How we’d reach the joints
- Where the property is
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll come back to you with a quote.
How the job changes by surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Windows and doors in Riverside of Blairs
With historic houses such as Friendville (about 3.3 miles north-east) nearby, there’s older building stock in the area around Riverside of Blairs as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Aberdeen is known as the Granite City, and sealing against granite needs clean, sound edges and a sealant that suits stone.
If you live in an older home near Cults West Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Portlethen station, renewing tired window mastic between tenants heads off draught and damp complaints.

What we’re called out for in Riverside of Blairs
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
These are the problems we are asked about most:
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
- Leaking joints at the ends of sills
- Cracked or shrunken mastic around the frame
Schools such as Cults Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- What happens if they find a problem under the old sealant
- What the cure time is
- How the joint is cleaned and prepared
- Whether you can choose the colour

What happens on the day
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before we start. Most jobs take most of a day for a typical house, less for a few frames. Outdoor work around Riverside of Blairs depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Move anything stored near the joints
- Let us know about earlier repairs to the joints
- Tell us about any water getting in

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Riverside of Blairs questions
Is Riverside of Blairs in your area for window mastic?
Yes. We work across all of Scotland, and Riverside of Blairs is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Will you come out to Riverside of Blairs?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can new window sealant be painted?
Not if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used before we leave.
Do you have insurance?
Yes. We’re fully insured, with over 20 years’ experience in sealant work.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Around Riverside of Blairs, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
