Window mastic for homes and businesses in Ravenswood
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on aluminium frames, patio & French doors and composite doors, and the jobs we see most are old mastic that has gone black or come away and hard, cracked sealant around windows.
Mastic can only go onto a dry joint, so outside work in Ravenswood depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
We stand behind the work with a 12-month guarantee.

What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
What we do, step by step
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 handful of frames, longer for a whole house. For a place like Ravenswood, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Mention any leaks or damp you’ve noticed

Why it’s worth doing now in Ravenswood
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a place like Ravenswood, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.

Ravenswood homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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 the older streets around St Mungo's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Managing a site like Our Lady's High? Then larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Greenfaulds station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Wipe condensation off the frames
- Avoid blasting the frames with a pressure washer
- Walk round the house once a year and look at the joints
- Avoid harsh chemicals near the mastic
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
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.
Ravenswood: your questions answered
Do you work for landlords with property near Greenfaulds station?
Yes. We work for letting agents and landlords as well as householders. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Do you cover Ravenswood for window mastic?
Yes. Our work covers the whole of Scotland, and Ravenswood is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
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.
How many windows can you do in a day?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we’re fully insured.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you seal inside as well as outside?
Yes. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.

DIY versus a professional finish
If you are 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 does not work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
