Window & door mastic in Parkgate, Dumfries and Galloway
Problem with your window and door frames in Parkgate? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- White mastic on grey or black frames
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Window mastic in Parkgate, done properly
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on timber windows & doors, composite doors and patio & French doors, and people most often call us about draughts coming in around windows and doors and gaps left after new windows were fitted.
Outdoor sealant needs a dry surface, so window work around Parkgate is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You get a one-year guarantee, the same in Parkgate as everywhere else we work.

What else we do in Parkgate
When it isn’t the sealant
We’ll always be straight with you, so here’s what new sealant won’t do:
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
If you’re not sure, just send an email to info@mrmastic.co.uk and we will give you a straight answer.

Signs you need window mastic in Parkgate
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
The problems people normally mention when they call are:
- Untidy mastic left by window fitters
- A bead that doesn’t match the frame
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
In the older streets around Kirkmichael Parish Church And Burial Ground, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What window mastic looks like in Parkgate
Sash and case windows are common in older Scottish homes, 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.
Around Parkgate, as everywhere, window mastic is only as good as the preparation behind it.

Work for landlords, hotels and businesses

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Keep solvents and bleach off the sealant
- Do not aim a pressure washer at the joints
- Look round the frames every year or so
- Repaint timber before it’s bare
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
What we do, step by step
The work is kept neat and contained to the area we’re working on. The job normally takes 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.

- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
