Window Mastic in Kelty
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Kelty. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill
What we are called out for in Kelty
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The problems people usually mention when they call include:
- A bead that does not match the frame
- Cracked sealant at the sill ends
- Untidy mastic left by window fitters
- Cracked internal joints between frame and plaster
Rented homes near Cowdenbeath station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Window mastic in Kelty, done properly
Homes in Kelty have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on patio & French doors, timber windows & doors and composite doors, and common reasons people get in touch are draughts coming in around windows and doors and old mastic that has gone black or come away.
In and around a place like Kelty, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
All our work is covered by our one-year guarantee.

What window mastic looks like in Kelty
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Beath High School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
When something else is needed
Before booking, it’s worth knowing the limits:
- Condensation trapped between the panes
- Faulty window hardware
- Rotten timber, which needs a joiner first
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- uPVC windows
- Aluminium frames
- Window sills
- Patio & French doors
- Composite doors
- Timber windows & doors
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid blasting the frames with a pressure washer
- Clean frames with a soft cloth and soapy water
- Check the mastic once a year
- Do not use solvent cleaners on the joint
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Kelty 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.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Keep children and pets away from the work area
- Tell us about any water getting in
- On commercial sites, let us know about site rules
