Window mastic for homes and businesses in Strachur
Around Strachur we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have sealant in the wrong colour for the frame and old mastic that has gone black or come away, we can help, on composite doors, patio & French doors and window sills alike.
Mastic can only go onto a dry joint, so outside work in Strachur depends on the weather. Let us know about access to every frame, including any upstairs.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Windows and doors in Strachur
Strachur is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Historic houses like Inveraray Castle (about 4.9 miles north) are a reminder that the area around Strachur has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Homes close to Kilmaglash Parish Church and Sculptured Stones include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Strachur is about 17 miles north-west of Helensburgh, in Argyll and Bute. Jobs in Strachur get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Strachur is one of 118 towns and villages in Argyll and Bute where we work. We also work in Glasgow, about 37 miles from Strachur.

What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- Mould in or behind the old joints
- The amount of work
- How many areas need sealing
- The type of sealant required
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Signs you need window mastic in Strachur
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
Signs it’s time to call us include:
- Old mastic that has gone black or come away
- Sealant in the wrong colour for the frame
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
In and around Strachur, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Different surfaces, different methods
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
Leave it or put it right?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. In a place like Strachur, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Why us?
- A choice of colours where the product allows
- Approved under the ARBOMaster scheme
- Anti-fungal silicone where joints get wet

What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours for a few frames, or a day or more for a whole house. Somewhere like Strachur may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Clean frames with a soft cloth and soapy water
- Look round the frames every year or so
- Avoid blasting the frames with a pressure washer
- Make sure the drainage slots aren’t blocked
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Strachur questions
Is Strachur within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Is window mastic in a coastal place like Strachur any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Can you do upstairs windows?
Generally, yes. Access is planned before work begins, so mention the height and anything in the way.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How do I get a quote for window mastic in Strachur?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Can new window sealant be painted?
That depends on the product. Some hybrid sealants can be painted; silicone cannot. Mention any painting plans before work begins.
