About our window mastic in Largoward
Around Largoward we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on uPVC windows, composite doors and aluminium frames, and common reasons people get in touch are cold air getting in at the frame edge and old mastic that has gone black or come away.
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.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Window mastic in Largoward: local notes
Historic houses like Gibliston House (about 2.5 miles south-east) are a reminder that the area around Largoward has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Homes close to Largoward 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. In and around Largoward, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How the visit works
Good joint work is mostly preparation, so that’s 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 few frames, or a day or more for a whole house. Somewhere like Largoward may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Mention any leaks or damp you’ve noticed
- Clear the area around the work
- Tell us about any previous sealing or DIY attempts

Related advice
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
FAQs for Largoward
Is Largoward within the area you cover?
Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Largoward in your area for window mastic?
Yes, Largoward is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job.
Do you guarantee window mastic?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we’ll tell you.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.

Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Landlord and commercial work in Largoward
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Looking after it afterwards
To keep the joints looking good and working properly:
- Look round the frames every year or so
- Wipe condensation off the frames
- Avoid harsh chemicals near the mastic
- Make sure the drainage slots aren’t blocked
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
What happens if it’s left?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Around Largoward, water from a failed joint in an older stone home can soak into timber and plaster.
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
