What we are called out for in Fernhill
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Signs it’s time to call us include:
- Mastic that has split away from the wall
- Rushed sealant from a window installation
- Mastic that’s falling out in pieces
- Sealant in the wrong colour for the frame
In the older streets around Stonelaw Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- How hidden problems are handled
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- How the colour is chosen

Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In a place like Fernhill, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

FAQs for Fernhill
Is Fernhill within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Burnside station?
Yes. We work for landlords and agents as well as homeowners. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Can I paint over the new sealant?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
How long before the joint can be used?
It depends on the product. Before we leave, we’ll tell you the cure time.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. 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 Fernhill need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Tell us if parking is tricky
- Tell us about any water getting in
- For indoor joints, keep the area dry beforehand if you can

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Check the mastic once a year
- Repaint timber before it’s bare
- Do not paint over the silicone
- Ventilate rooms so frames do not stay wet inside
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
