Window mastic in Dedridge
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you are dealing with untidy mastic left by window fitters and sealant in the wrong colour for the frame, we can put it right, on uPVC windows, patio & French doors and window sills alike.
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.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
Every job is quoted individually, so start by telling us what you need. Simply send an email to info@mrmastic.co.uk and describe the job and send pictures if you have them.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- A failed sealed unit that has misted up
- Penetrating damp from a failed cavity tray or render
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before booking.
Joints and surfaces we work on
- uPVC windows
- Composite doors
- Patio & French doors
- Aluminium frames
- Window sills
- Timber windows & doors
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Keep paint off silicone joints
- Use gentle cleaners on frames and sealant
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Questions from Dedridge
Do you cover Dedridge for window mastic?
Yes. Our work covers the whole of Scotland, and Dedridge is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Is Dedridge within the area you cover?
Yes. Dedridge is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do the sealants smell?
There can be a smell while the sealant cures. Opening a window helps.
How long does it take to reseal the windows on a house?
Allow a morning for a couple of windows and a door. Access and the amount of old mastic make the biggest difference.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Dedridge homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. With historic houses such as Howden House (about 0.9 miles north) nearby, there’s older building stock in the area around Dedridge as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as St. Margaret's Academy are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Livingston South station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Dedridge
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
Why Dedridge clients choose us
- Old sealant always removed completely
- Tidy, careful work
- White, clear, grey or coloured to suit, where the product allows
- Quality sealants from Arbo and Everbuild

Signs you need window mastic in Dedridge
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.
People generally contact us when they notice something like this:
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
- Draughts coming in around windows and doors
In the older streets around Livingston Parish Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

The process
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and tidy away. It generally takes a few hours for a handful of frames, longer for a whole house. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
