- Cracked or shrunken mastic around the frame
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Window mastic in Loganlea
Homes in Loganlea have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, patio & French doors and timber windows & doors, and the jobs we see most are damp patches on the reveal after heavy rain and draughty joints inside around the window.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Each job carries a 12-month guarantee, whatever its size.

What else we do in Loganlea
For landlords and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes most of a day for a typical house, less for a few frames. For a place like Loganlea, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Clear the area around the work

What affects the cost of window mastic
Call for a quick quote. The main things that affect it are:
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
When you contact us, it’s useful to know:
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- Where the property is
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.

I let a flat near Addiewell station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Will the old sealant be removed?

Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
When it isn’t the sealant
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Damp coming through the wall itself rather than the frame joint
- Worn gaskets, brush seals or a door that has dropped
- A sash or casement that won’t close properly
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- uPVC windows
- Patio & French doors
- Timber windows & doors
- Composite doors
- Aluminium frames
- Window sills
Common problems we fix in Loganlea
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
Keep an eye out for these signs:
- Gaps between the frame and the inside reveal
- White mastic on grey or black frames
- Mastic that is falling out in pieces
- Damp patches on the reveal after heavy rain
If you live in an older home near Addiewell Church Of Scotland, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Do not paint over the silicone
- Keep timber frames painted
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
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 send an email to info@mrmastic.co.uk.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Loganlea homes and the weather
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For landlords with property near Addiewell station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
