Window mastic for homes and businesses in Tighnabruaich
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you have old mastic that has gone black or come away and white mastic on grey or black frames, we can help, on patio & French doors, timber windows & doors and uPVC windows alike.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
All our work comes with a one-year guarantee.

FAQs for Tighnabruaich
Is Tighnabruaich within the area you cover?
Yes. Tighnabruaich is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Does living near the coast affect window mastic in Tighnabruaich?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
How long does it take to reseal the windows on a house?
A handful of frames is a short visit. You’ll get a timescale with the quote.
What does window mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk and tell us what needs doing and where.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
We also work for property managers and facilities teams. We can quote a run of properties together.
What we are called out for in Tighnabruaich
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
The problems people normally mention when they call are:
- Gaps where the sill meets the wall
- Black, perished sealant on frames
- Rushed sealant from a window installation
- A bead that does not match the frame
In and around Tighnabruaich, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- The length of the guarantee
- What the cure time is
- Are they insured?
- How the colour is chosen
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Aftercare tips
How long the joints last depends on use and care. We suggest:
- Ventilate rooms so frames don’t stay wet inside
- Keep drainage slots and sill grooves clear
- Avoid harsh chemicals near the mastic
- Keep paint off silicone joints
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
What affects the quote in Tighnabruaich
The price is agreed before any work begins. It takes into account:
- The number and length of the joints
- Any mould that needs treating
- Which sealant suits the joint
- The old material and how stubborn it is
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we’ll go through it with you.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, drop us a line at info@mrmastic.co.uk.
What happens on the day
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. Outside jobs in Tighnabruaich 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 is not affected.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

Windows and doors in Tighnabruaich
Tighnabruaich 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.
If you live in an older home near Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
