Window & door mastic in Balnabruich, Highland
Professional window mastic in and around Balnabruich, with every bit of old sealant taken out first.
- Damp patches on the reveal after heavy rain
- Leaking joints at the ends of sills
- Gaps between the frame and the inside reveal
Window mastic in Balnabruich
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you are dealing with cracked internal joints between frame and plaster and cold air getting in at the frame edge, we can help, on patio & French doors, window sills and timber windows & doors alike.
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.
All of our work is guaranteed for twelve months, in Balnabruich and everywhere else we cover.

Balnabruich homes and the weather
Balnabruich is close to 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For jobs in and around Balnabruich, choosing the right material for each joint is as important as a tidy finish. Around Balnabruich, as everywhere, window mastic is only as good as the preparation behind it.

Questions from Balnabruich
Is window mastic in a coastal place like Balnabruich any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Will you come out to Balnabruich?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do you have sealant for grey or black windows?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Is the new sealant paintable?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can tenants book the work?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house. Outside jobs in Balnabruich need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors isn’t affected.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
Before we arrive
- Move anything stored near the joints
- Mention any tricky access
- Mention if the joints have been sealed before

What affects the cost of window mastic
The price is agreed before any work begins. It’s based on:
- The size of the job
- Which sealant suits the joint
- When we can work, for business premises
- How easy the joints are to reach
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The problem you’ve noticed
- If someone has resealed it before
- The type of property
- Photos by email, if that’s easy
To get a quote, email us at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. You’ll have a clear quote before any work starts.

How the job changes by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Why act early in Balnabruich
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In an older home around Balnabruich, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Doing several joints on one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Why book with us
- An ARBOMaster approved applicator
- A choice of colours where the product allows
- Every job guaranteed for a year
- You choose the colour before work begins

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
When something else is needed
Before booking, it’s worth knowing the limits too:
- Broken hinges, locks or handles
- Soft or decayed wood in the frame
- Damp problems in the wall away from the window
If in doubt, email us at info@mrmastic.co.uk and we’ll say what we think before booking.
