Window mastic in Kilmartin
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you’re dealing with cracked sealant at the sill ends and cracked or shrunken mastic around the frame, we can help.
Outdoor sealant needs a dry surface, so window work around Kilmartin is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything is not right with it, email us at info@mrmastic.co.uk.

Quotes for window mastic in Kilmartin
For a quick quote, just ask. What matters most is:
- Working hours on commercial sites
- Whether there’s mould to deal with
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
Helping us quote
Before you ask for a quote, have a think about:
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- If someone has resealed it before
To get a quote, send an email to info@mrmastic.co.uk with the location and a short description of the problem. We’ll send you a clear quote before any work starts.
What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. 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.
When to call us in Kilmartin
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
The most common problems we see are:
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
- Water coming in at the bottom corners of a door
- Gaps where the sill meets the wall
If you live in an older home near Kilmartin Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- How long to leave it before use
- Which colour the sealant will be
- What happens if the job turns out different
- How much experience the applicator has

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When something else is needed
It helps to know what we can’t do:
- Condensation trapped between the panes
- Faulty window hardware
- Damp coming through the wall itself rather than the frame joint
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.

How it works
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself normally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. For a place like Kilmartin, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Before we arrive
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky

Advice
What window mastic looks like in Kilmartin
Kilmartin is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
In and around Kilmartin, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Leave it or put it right?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk and we’ll talk you through it.
