Crawford Window Mastic
Window mastic in Crawford from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Why it’s worth doing now in Crawford
The work is quick compared with the damage it prevents: it takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

Window mastic for homes and businesses in Crawford
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you have whistling draughts around closed windows and mastic that has split away from the wall, we can help, on composite doors, patio & French doors and timber windows & doors alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
You get a 12-month guarantee, the same in Crawford as everywhere else we work.

What affects the quote in Crawford
We quote each job individually. This is what makes a difference:
- Working hours on commercial sites
- The number of rooms or windows
- The product the joint needs
- The amount of work
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Where the job is, and your postcode
- The rough size of the job
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job.
The process
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. Outside jobs in Crawford need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- We check how each frame can be reached safely.
- 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.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Faulty window hardware
- Penetrating damp from a failed cavity tray or render
- 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 will tell you honestly.
What we seal
- Patio & French doors
- Aluminium frames
- uPVC windows
- Timber windows & doors
- Composite doors
- Window sills
Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
What window mastic looks like in Crawford
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional 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.
In the older streets around Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Crawford questions
Do you cover smaller places like Crawford?
Yes, Crawford is covered. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Crawford for window mastic?
Yes. We work across all of Scotland, and Crawford is part of that. Just email us at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Can you seal over the old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long does it take to reseal the windows on a house?
It depends on access, the old mastic and the size of the frames. We’ll tell you how long your job needs when we quote.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.

Do you need window mastic in Crawford?
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
Common reasons people contact us are:
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- Draughts coming in around windows and doors
- Hard, cracked sealant around windows
In and around Crawford, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
