Window mastic in Mochrum, done properly
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that cannot move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. If you’re dealing with rushed sealant from a window installation and mastic that’s falling out in pieces, we can put it right, on composite doors, timber windows & doors and aluminium frames alike.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You’re covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Signs you need window mastic in Mochrum
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid cannot stretch. That is what backing rod is for.
Any of these means the joints need attention:
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
- Old mastic that has gone black or come away
In the older streets around Kirk of Mochrum, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why act early in Mochrum
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In an older home around Mochrum, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

Mochrum questions
Will you come out to Mochrum?
Yes. Mochrum 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.
Is Mochrum in your area for window mastic?
Yes, Mochrum is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Is the work guaranteed?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

Quotes for window mastic in Mochrum
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- Access and height
- The size of the job
- When we can work, for business premises
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- How we’d reach the joints
- Where the property is
- The problem you’ve noticed
Every job is quoted individually. Simply drop us a line at info@mrmastic.co.uk and describe the job and send photos if you have them.
Can I do it myself?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Mochrum and across Dumfries and Galloway. Several sites can go on one quote, and we’re fully insured for the work.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep timber frames painted
- Keep paint off silicone joints
- Air rooms to keep condensation down around windows
- Make sure the drainage slots are not blocked
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Mochrum homes and the weather
Mochrum is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
In and around Mochrum, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
