Strone Window Mastic
Problem with your window and door frames in Strone? We remove the old material, prepare the joints and seal them properly.
- Draughts coming in around windows and doors
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
Honest limits
A few problems are outside what sealant work can do:
- A sash or casement that won’t close properly
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first

Window mastic for homes and businesses in Strone
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you are dealing with water coming in at the bottom corners of a door and cracked sealant at the sill ends, we can put it right, whatever the surface.
Outdoor sealant needs a dry surface, so window work around Strone is planned around the weather. Let us know about access to every frame, including any upstairs.
Each job carries a 12-month guarantee.

What else we do in Strone
Aftercare tips
After the cure time, these simple habits help:
- Keep drainage slots and sill grooves clear
- Walk round the house once a year and look at the joints
- Keep timber frames painted
- Keep solvents and bleach off the sealant
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.
What the job involves on each surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We will tell you if that’s what we find.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
The process
Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes most of a day for a typical house, less for a few frames. In smaller Scottish places, parking is generally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Related advice
Why deal with it now?
Draughts and leaks do not always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
The cost depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.

What window mastic looks like in Strone
Strone is close to 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. Strone is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
Rented homes near Gourock station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Dunoon Grammar School, the mastic around its windows and doors needs looking after like any other building’s.

Common questions in Strone
Does the coastal weather in Strone affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.

Yes. We work for landlords and letting agents as well as homeowners. You can send an email to info@mrmastic.co.uk with the details for a clear quote.

How much does window mastic cost in Strone?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Will there be a smell?
Some sealants have a smell while they cure. Opening a window helps.
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.
DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Signs you need window mastic in Strone
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Water coming in at the bottom corners of a door
- Mastic that has split away from the wall
- Sealant in the wrong colour for the frame
- Rushed sealant from a window installation
For an older house near a landmark such as Strone Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
