How we handle sand mastic in Parkhouse
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you are dealing with mastic that needs renewing before redecorating and modern sealant on a period surround, we can put it right, on tenement windows, sash and case windows and period & listed homes 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, so the mastic there works hard.
Your job is guaranteed for a year, as with all our work.

FAQs for Parkhouse
Is Parkhouse within the area you cover?
Yes, Parkhouse is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Parkhouse for sand mastic?
Yes. We work across all of Scotland, and Parkhouse is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What guarantee comes with the work?
Every job comes with our 12-month guarantee.
Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In an older home around Parkhouse, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we will quote.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Windows and doors in Parkhouse
Parkhouse is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out. With historic houses such as Tenement House (about 1.7 miles south-west) nearby, there’s older building stock in the area around Parkhouse as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Ashfield station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as St. Roch's Secondary School, larger buildings have plenty of frames, and the mastic around each one ages.

Looking after it afterwards
So the new joints stay in good condition:
- Go gently near the mastic when preparing windows
- Ask a joiner to look at soft timber first
- Clear gutters so water doesn’t pour onto the windows
- Plan mastic work ahead of painting
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
How the visit works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. Most jobs take a few hours per window, depending on the condition of the joints. For a place like Parkhouse, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises
- Clear the area around the work
