Window mastic in Waterside, done properly
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have black, perished sealant on frames and damp patches on the reveal after heavy rain, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All of our work is guaranteed for twelve months, in Waterside and everywhere else we cover.

What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- The amount of work
- Which sealant suits the joint
- Any working-time requirements on site
- How many rooms, windows or areas are involved
Doing several joints on one visit generally makes better use of the time than several visits. We will give you a clear quote for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
- The address or postcode of the job
- How we’d reach the joints
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, email us at info@mrmastic.co.uk.
What we are called out for in Waterside
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. Backing rod sets the right depth.
Signs it’s time to call us include:
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
- Gaps left after new windows were fitted
- Mastic that’s falling out in pieces
Around Waterside, as everywhere, window mastic is only as good as the preparation behind it.

What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take 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. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- Tell us if parking is tricky

Advice
How the job changes by surface
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
What happens if it’s left?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a place like Waterside, 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 price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Over 20 years’ experience
- We agree the colour with you first
- Tidy, careful work

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Avoid blasting the frames with a pressure washer
- Clear any debris from frame drain holes
- Paint up to the joint, not over it
- Ventilate rooms so frames do not stay wet inside
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Window mastic in Waterside: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Waterside 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.
For an older house near a landmark such as Waterside and Lethanhill Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When it isn’t the sealant
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
- Broken hinges, locks or handles

Waterside: your questions answered
Is Waterside within the area you cover?
Yes. Waterside is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
What guarantee comes with window mastic in Waterside?
Every job comes with our 12-month guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you work for letting agents?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch so we can plan the job.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
