Window mastic in Westmuir, done properly
Over two decades of sealing frames has taught us which products suit which walls. We’re fully insured ARBOMaster approved applicators, and every job is covered by a 12-month guarantee. We work on window sills, aluminium frames and composite doors, and people most often call us about draughts coming in around windows and doors and black, perished sealant on frames.
In and around a place like Westmuir, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
You get a 12-month guarantee, the same in Westmuir as everywhere else we work.

Can I do it myself?
The difference is mostly in the preparation and the 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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Quotes for window mastic in Westmuir
We quote each job individually. These are the things that affect it:
- The amount of work
- When we can work, for business premises
- The number of rooms or windows
- Mould in or behind the old joints
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Asking for a quote
What to tell us when you ask for a quote:
- What’s wrong with the joints now
- Whether it’s a home or a business
- The address or postcode of the job
- Photos by email, if that’s easy
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.
How it works
We keep the work tidy and contained to the joints we’re treating. Expect the work to take most of a day for a typical house, less for a few frames. Somewhere like Westmuir 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 each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

What the job involves on each surface
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Aftercare tips
After the cure time, these simple habits help:
- Keep jet washers away from the mastic
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
- Clean frames with a soft cloth and soapy water
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Windows and doors in Westmuir
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. With historic houses such as Glamis Castle (about 3.1 miles south-east) nearby, there’s older building stock in the area around Westmuir as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In and around Westmuir, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

When to call us in Westmuir
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Any of these means the joints need attention:
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
- Draughts coming in around windows and doors
Historic houses such as Glamis Castle, about 3.1 miles south-east, show how far back building around Westmuir goes.
