How we handle window mastic in Newhills
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on uPVC windows, composite doors and patio & French doors, and the jobs we see most are untidy mastic left by window fitters and draughts coming in around windows and doors.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

How we quote for window mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- The size of the job
- The type of sealant required
- How many rooms, windows or areas are involved
- Any working-time requirements on site
We don’t 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.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- Where the job is, and your postcode
- Whether it has been sealed before
- Roughly how big the job is
- Pictures of the joints, sent by email
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will talk you through the work.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Avoid blasting the frames with a pressure washer
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots aren’t blocked
- Keep solvents and bleach off the sealant
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, 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. Outdoor work around Newhills depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Clear the area around the work
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Advice
What sealant work cannot fix
Before booking, it’s worth knowing the limits too:
- Damp coming through the wall itself rather than the frame joint
- A door that needs adjusting, rehanging or new seals
- Soft or decayed wood in the frame
If you’re not sure, just drop us a line at info@mrmastic.co.uk and we will give you a straight answer.

What else we do in Newhills
What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Why us?
- Experience in homes, commercial sites and hotels
- Arbo and Everbuild products
- 20+ years of sealant experience
- Anti-fungal silicone where joints get wet

Does the work come with a guarantee?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Can new window sealant be painted?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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, then guaranteed for a year.
Window mastic in Newhills: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. With historic houses such as Friendville (about 4.2 miles south-east) nearby, there’s older building stock in the area around Newhills as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Bucksburn Academy, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Old Parish Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. Rented homes near Dyce station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
