Window mastic in Letham
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on uPVC windows, patio & French doors and aluminium frames, and the jobs we see most are gaps between the frame and the inside reveal and a bead that doesn’t match the frame.
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.
Whatever the size of the job, you get the same 12-month guarantee in Letham and across Perth and Kinross.

The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. Around Letham, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints

FAQs for Letham
I let a flat near Perth station. Can you help?
Yes. We work for landlords and agents as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Letham?
Yes, Letham is covered. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before any work starts.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
What do you need from me for a quote?
Let us know what needs doing and where, plus pictures if you have them. We’ll ask anything else we need to know.
Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a place like Letham, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.

Do you need window mastic in Letham?
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The most common problems we see are:
- White mastic on grey or black frames
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
Letting a property close to Perth station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What your quote should include

- How the joint is cleaned and prepared
- Is the old sealant removed completely?
- How much experience the applicator has
Window mastic in Letham: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Managing a site like Perth High School? Then its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t aim a pressure washer at the joints
- Check the mastic once a year
- Use gentle cleaners on frames and sealant
- Make sure the drainage slots aren’t blocked
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal. Neutral-cure sealant is the safe choice.
