Cuminestown Window Mastic

- Damp patches on the reveal after heavy rain
Window mastic for homes and businesses in Cuminestown
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on composite doors, uPVC windows and aluminium frames, and the jobs we see most are hard, cracked sealant around windows and sealant in the wrong colour for the frame.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Surface by surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
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. White is the usual colour, with brown, anthracite grey and black for coloured frames.
What affects the quote in Cuminestown
We do not publish a price list. What we look at:
- When we can work, for business premises
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- The number of rooms or windows
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- Where the job is, and your postcode
- Any previous sealing or DIY work
- Whether it’s a home or a business
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.
Cuminestown homes and the weather
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
Homes close to Monquhitter Parish Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions from Cuminestown
Can you do window mastic in Cuminestown?
Yes. We work across all of Scotland, and Cuminestown is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Is there a guarantee on window mastic in Cuminestown?
All our work, in Cuminestown and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Can you seal the gap between the frame and the plaster indoors?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.
How many windows can you do in a day?
A handful of frames is a short visit, while a whole house takes longer. We confirm the timing with your quote.
Can you reach windows above the ground floor?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes most of a day for a typical house, less for a few frames. Around Cuminestown, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Tell us about any water getting in
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, email us at info@mrmastic.co.uk for an honest opinion and a quote.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep jet washers away from the mastic
- Paint up to the joint, not over it
- Check the mastic once a year
- Make sure the drainage slots are not blocked
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Landlord and commercial work in Cuminestown
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
What we’re called out for in Cuminestown
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Any of these means the joints need attention:
- Cracked or shrunken mastic around the frame
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
In and around Cuminestown, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
