What affects the quote in St Madoes
Your quote is based on your job. We look at:
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How we handle window mastic in St Madoes
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you are dealing with whistling draughts around closed windows and rushed sealant from a window installation, we can put it right, on window sills, patio & French doors and timber windows & doors alike.
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.
Whatever the size of the job, it’s backed by our 12-month guarantee in St Madoes and across Perth and Kinross.

For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Landlords and letting agents in St Madoes can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
What we do, step by step
At the end, we look at the finished work together. The visit itself normally takes a morning for a couple of windows and a door, depending on the size of the job. Outside jobs in St Madoes need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Clear items away from the joints we are working on
- Keep pets and children clear of the area while we work
- Where the joints are inside, avoid wetting them before we arrive

Advice
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
What happens if it’s left?
Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In a place like St Madoes, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.

Windows and doors in St Madoes
St Madoes is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For an older house near a landmark such as St Madoes Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

What we’re called out for in St Madoes
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Any of these means the joints need attention:
- White mastic on grey or black frames
- Black, perished sealant on frames
- Water coming in at the bottom corners of a door
- Draughts coming in around windows and doors
In and around St Madoes, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Keep jet washers away from the mastic
- Use gentle cleaners on frames and sealant
- Keep solvents and bleach off the sealant
- Ventilate rooms so frames don’t stay wet inside
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

St Madoes: your questions answered
Can you do window mastic in St Madoes?
Yes, St Madoes is within the area we cover. Our work covers the whole of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Does living near the coast affect window mastic in St Madoes?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can you get sealant to suit coloured frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.
