Humbie Window Mastic
Window mastic for Humbie and the surrounding area: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Sealant in the wrong colour for the frame
- Hard, cracked sealant around windows
- Gaps left after new windows were fitted
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Do not use solvent cleaners on the joint
- Check the mastic once a year
- Wipe condensation off the frames
- Paint up to the joint, not over it
Silicone can’t usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
About our window mastic in Humbie
Around Humbie we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on window sills, uPVC windows and patio & French doors, and people most often call us about water coming in at the bottom corners of a door and cold air getting in at the frame edge.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A one-year guarantee comes as standard, so you are covered after we’ve gone.

What guarantee comes with window mastic in Humbie?

Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned.

Will there be a smell?
Possibly a little. It fades as the sealant cures.
I rent my home. Can I book you?

Do you work on first-floor windows?

Quotes for window mastic in Humbie
There’s no set price list. The quote depends on:
- When we can work, for business premises
- The amount of work
- Whether the work is at height
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Helping us quote
When you call or email, it’s useful to know:
- A few pictures by email, if you can
- The rough size of the job
- Whether it has been sealed before
- Any access issues, like height or stairs
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

Honest limits
We will not take on work that won’t last, so these are the limits:
- A sash or casement that won’t close properly
- Damp coming through the wall itself rather than the frame joint
- A frame that has rotted at the joint
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think.
Where we work in Humbie
- Patio & French doors
- uPVC windows
- Aluminium frames

- Timber windows & doors
- Composite doors
Why act early in Humbie
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In an older home around Humbie, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk and we’ll talk you through it.
Why book with us

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the job takes a morning for a couple of windows and a door in most cases. Around Humbie, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can

What the job involves on each surface
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. We match the colour to the frame.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
Windows and doors in Humbie
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.
In and around Humbie, as anywhere, good window mastic starts with a clean, dry, properly prepared joint. Homes close to Humbie Parish Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
