Your questions about window mastic in Drumvaich
Is there a guarantee on window mastic in Drumvaich?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Is Drumvaich in your area for window mastic?
Yes, Drumvaich is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we will give you a clear price.
Is the new sealant paintable?
Silicone generally won’t take paint. Let us know beforehand, and we’ll use a paintable product where it suits.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Window mastic for homes and businesses in Drumvaich
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you’re dealing with draughty joints inside around the window and water coming in at the bottom corners of a door, we can put it right, whatever the surface.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

What affects the cost of window mastic
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- Mould in or behind the old joints
- Working hours on commercial sites
Combining jobs into one visit is usually more efficient than separate visits. We’ll send you a clear quote for the lot.
Helping us quote
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- The address or postcode of the job
- Photos by email, if that is easy
- Any previous sealing or DIY work
To get a quote, send an email to info@mrmastic.co.uk with the location and a short description of the problem. We’ll give you a clear price before any work starts.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Look round the frames every year or so
- Clear any debris from frame drain holes
- Keep paint off silicone joints
- Keep jet washers away from the mastic
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
How the visit works
When we arrive, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. Outside jobs in Drumvaich need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

Frames and glazing around Drumvaich
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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For jobs in and around Drumvaich, choosing the right material for each joint is as important as a tidy finish.

Common problems we fix in Drumvaich
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.
Signs it’s time to call us include:
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- Old mastic that has gone black or come away
- Rushed sealant from a window installation
In and around Drumvaich, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In an older home around Drumvaich, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before we start. It won’t solve:
- Damp coming through the wall itself rather than the frame joint
- Broken hinges, locks or handles
- Misting between the panes of a double-glazed unit (that needs a new unit)
