Leave it or put it right?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a place like An Luirg, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Window mastic in An Luirg, done properly
Around An Luirg we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on composite doors, uPVC windows and aluminium frames, and people most often call us about damp patches on the reveal after heavy rain and mastic that has split away from the wall.
In and around a place like An Luirg, 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.
Big or small, you get the same one-year guarantee in An Luirg and across Highland.

How we quote for window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- When we can work, for business premises
- The number of rooms or windows
- The type of sealant required
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. The price is agreed before we begin.
Asking for a quote
To help us quote quickly, please include:
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- What’s wrong with the joints now
- Roughly how big the job is
Need a quote? Please send an email to info@mrmastic.co.uk and tell us about the job. You will know what we plan to do, and what it will cost, before any work begins.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Landlords, agents and businesses in An Luirg
In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Ventilate rooms so frames don’t stay wet inside
- Don’t use solvent cleaners on the joint
- Clear any debris from frame drain holes
- Paint up to the joint, not over it
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
The process
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a morning for a couple of windows and a door. Somewhere like An Luirg may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any water getting in
- Keep children and pets away from the work area
Getting a quote
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you are ready, send an email to info@mrmastic.co.uk.

Yes, we do. We work across all of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
What does window mastic cost?
We don’t publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Where do you work from?
We work from Crawley. We cover An Luirg and the rest of Highland, along with the rest of our area.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Will new mastic stop draughts?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.

Yes. Just list everything you need.
Do you work for landlords and businesses?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels in An Luirg.
An Luirg homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Around An Luirg, as everywhere, window mastic is only as good as the preparation behind it.

Signs you need window mastic in An Luirg
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch when they notice something like this:
- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
- White mastic on grey or black frames
- Black, perished sealant on frames
Letting a property close to Lairg station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
