Window Mastic in Murieston
Window and door frames in Murieston need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Draughts coming in around windows and doors
- Cracked sealant at the sill ends
- White mastic on grey or black frames
Looking after it afterwards
Looking after new joints is easy:
- Do not aim a pressure washer at the joints
- Use gentle cleaners on frames and sealant
- Do not paint over the silicone
- Walk round the house once a year and look at the joints
Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
Window mastic for homes and businesses in Murieston
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. We work on timber windows & doors, uPVC windows and aluminium frames, and common reasons people get in touch are old mastic that has gone black or come away and a bead that doesn’t match the frame.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
You get a 12-month guarantee, the same in Murieston as everywhere else we work.

What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- Whether there’s mould to deal with
- The number of rooms or windows
- When we can work, for business premises
- Whether the work is at height
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference.

When you call or email, it’s useful to know:
- The problem you’ve noticed
- Photos by email, if that is easy

Common questions in Murieston
Will you come out to Murieston?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Murieston in your area for window mastic?
Yes. We work across all of Scotland, and Murieston is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you work for letting agents?
Yes, often. Several properties can go on one quote.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Window mastic in Murieston: local notes
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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
If you look after a building such as Inveralmond Community High School, larger buildings have plenty of frames, and the mastic around each one ages. Historic houses such as Howden House, about 1.8 miles north, show how far back building around Murieston goes. Letting a property close to Livingston South station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
What happens if it’s left?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. Around Murieston, 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.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

When it isn’t the sealant
We’d rather tell you now than do work that will not last, so these are the limits:
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly before booking.

How the visit works
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. Outside jobs in Murieston need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
