Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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.
Glazing silicone in Closeburn, done properly
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. If you’re dealing with stained, discoloured glazing silicone and leaks from the base of a shower screen, we can put it right, on glass balustrade bases, rooflights and conservatory frames alike.
Mastic can only go onto a dry joint, so outside work in Closeburn depends on the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, it’s backed by our 12-month guarantee in Closeburn and across Dumfries and Galloway.

Windows and doors in Closeburn
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
If you live in an older home near Closeburn Parish Church, the joint between an old wall and a newer frame is normally the first place rain gets in.
Closeburn is about 11 miles north-west of Dumfries, in Dumfries and Galloway. Every kind of property in Closeburn is covered for glazing silicone, old or new, large or small. The work is guaranteed for a year. Across Dumfries and Galloway, we cover 138 places, and Closeburn is one of them. Glasgow is on our list too, around 49 miles away.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Stick to mild cleaners on glass
- Avoid strong solvents on or near the sealant
- Act on drips or damp patches early
- Inspect the sealant on glazing annually
Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.
What we’re called out for in Closeburn
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
Signs it’s time to call us include:
- Sealant that was laid over old silicone and failed
- Failed sealant around rooflight glass
- Split or lifting silicone on glass
- Leaks from the base of a shower screen
Schools such as Wallace Hall Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Your questions about glazing silicone in Closeburn
Is glazing silicone in Closeburn guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Closeburn?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Are you insured?
Yes. Mr Mastic is fully insured.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours, and we’ll agree it with you first.
The process
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many joints need doing and we leave things clean and tidy. Outside jobs in Closeburn 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 is not affected.
- First we agree the joints to be done.
- We cut away the failed silicone.
- We clean and prepare the joint.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Try not to wet indoor joints just before the visit

What happens if it’s left?
A new conservatory roof is a big job. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we’ll tell you. Around Closeburn, water from a failed joint in an older stone home can soak into timber and plaster.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- Colour agreed with you before we start
- Old sealant always removed completely
