Fintry questions
Do you cover smaller places like Fintry?
Yes. Fintry is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is there a guarantee on window mastic in Fintry?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Can I paint over the new sealant?
That depends on the product. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we will choose accordingly.
Do you work for landlords and businesses?
Yes. We work in homes, commercial premises and hotels.
Can you get sealant to suit coloured frames?
Normally, yes. Tell us the frame colour when you get in touch and we will match it as closely as we can.
Do you have insurance?
Yes. Full insurance covers our work.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
About our window mastic in Fintry
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. If you’re dealing with rushed sealant from a window installation and rain getting in at the frame or under the sill, we can help, on composite doors, aluminium frames and uPVC windows alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All our work is covered by a 12-month guarantee, wherever you are in Stirling.

Signs you need window mastic in Fintry
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
People normally contact us when they notice something like this:
- Draughty joints inside around the window
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
For an older house near a landmark such as Old Fintry Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- Whether the sealant suits the joint
- How long the guarantee is
- How much experience the applicator has
- How the joint is cleaned and prepared

Why it’s worth doing now in Fintry
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In a place like Fintry, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What you get with us
- White, clear, grey or another colour, product permitting
- A 12-month guarantee on all work
- A sealant colour to suit the surroundings
- You choose the colour before work begins

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.

Aftercare tips
A little care helps the new joints last. Our advice:
- Make sure the drainage slots are not blocked
- Look round the frames every year or so
- Keep jet washers away from the mastic
- Ventilate rooms so frames don’t stay wet inside
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Damp coming through the wall itself rather than the frame joint
- Faulty window hardware
- Rotten timber, which needs a joiner first

What affects the cost of window mastic
You’ll get a clear quote before we start. It takes into account:
- Mould in or behind the old joints
- The amount of work
- The product the joint needs

Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it’s a home or a business
- Any access issues, like height or stairs
- If someone has resealed it before

Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we’ll talk you through the work.
Frames and glazing around Fintry
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. Fintry is in the west of Scotland, which is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Around Fintry, as everywhere, window mastic is only as good as the preparation behind it.

What happens on the day
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. Outdoor work around Fintry depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
