How the job changes by surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as that’s a job for a joiner.
Signs you need window mastic in Na h-Eileanan an Iar
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That’s what backing rod is for.
Most people get in touch when they notice one of these:
- Gaps where the sill meets the wall
- Gaps between the frame and the inside reveal
- A bead that doesn’t match the frame
- Rushed sealant from a window installation
Whether the job is in Na h-Eileanan an Iar itself or nearby, the right material for each joint matters as much as a neat finish.

What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- How many areas need sealing
- Which sealant suits the joint
- Any working-time requirements on site
- Mould in or behind the old joints
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Helping us quote
When you contact us, these details help:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- What’s wrong with the joints now
- Where the property is
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep jet washers away from the mastic
- Check the mastic once a year
- Make sure the drainage slots aren’t blocked
- Avoid harsh chemicals near the mastic
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just email us at info@mrmastic.co.uk.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
When it is not the sealant
It helps to know what we can’t do:
- Damp coming through the wall itself rather than the frame joint
- A door that needs adjusting, rehanging or new seals
- A failed sealed unit that has misted up
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

Your questions about window mastic in Na h-Eileanan an Iar
Is window mastic in a coastal place like Na h-Eileanan an Iar any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is Na h-Eileanan an Iar within the area you cover?
Yes. Na h-Eileanan an Iar is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Can you match the sealant to my frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you are decorating and we will choose accordingly.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
How long will my window job take?
Allow a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Leave it or put it right?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Around Na h-Eileanan an Iar, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
Why us?
- We leave the area clean and tidy
- We never seal over old sealant
- Every job guaranteed for a year

How it works

- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
