Tayvallich Window Mastic
Problem with your window and door frames in Tayvallich? We cut out the old, prepare the joints and apply the right sealant, with a 12-month guarantee.
- Draughty joints inside around the window
- Cracked or shrunken mastic around the frame
- Water coming in at the bottom corners of a door
How we handle window mastic in Tayvallich
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We are often asked to deal with leaking joints at the ends of sills and rushed sealant from a window installation, on timber windows & doors, composite doors and aluminium frames.
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.

What happens if it’s left?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a place like Tayvallich, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises
- Tell us about access, such as stairs, a lift or high-level joints

Advice
When to call us in Tayvallich
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Signs it’s time to call us include:
- Gaps left after new windows were fitted
- Water coming in at the bottom corners of a door
- White mastic on grey or black frames
- Leaking joints at the ends of sills
In the older streets around Tayvallich Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Questions to ask before booking
- How much experience the applicator has
- What insurance they hold
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
Honest limits
We won’t take on work that will not last, so these are the limits:
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly before booking.

Tayvallich homes and the weather
Tayvallich is within about 1 mile of 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. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
Around Tayvallich, as everywhere, window mastic is only as good as the preparation behind it.

FAQs for Tayvallich
Will you come out to Tayvallich?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Does living near the coast affect window mastic in Tayvallich?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Make sure the drainage slots aren’t blocked
- Do not aim a pressure washer at the joints
- Paint up to the joint, not over it
- Look round the frames every year or so
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. 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 we quote for window mastic
Every job gets its own quote. These are the things that affect it:
- Whether the work is at height
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
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. You’ll know the price before we begin.
Helping us quote
You do not need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- How we’d reach the joints
