Window Mastic in Exnaboe
We cover Exnaboe for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Gaps left after new windows were fitted
- A bead that does not match the frame
- Gaps where the sill meets the wall
Why it’s worth doing now in Exnaboe
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Around Exnaboe, water from a failed joint in an older stone home can soak into timber and plaster.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

- Rated 4.9 stars on Google

Window mastic in Exnaboe, done properly
Homes in Exnaboe have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have gaps where the sill meets the wall and a bead that doesn’t match the frame, we can help, on uPVC windows, 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. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Whatever the size of the job, you get the same 12-month guarantee.

What we are called out for in Exnaboe
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. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Gaps between the frame and the inside reveal
- A bead that doesn’t match the frame
- Black, perished sealant on frames
- Cold air getting in at the frame edge
Whether the job is in Exnaboe itself or nearby, the right material for each joint matters as much as a neat finish.
Before you book anyone
- The length of the guarantee
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- Is VAT in the price?
What affects the cost of window mastic
The price is agreed before any work begins. It’s based on:
- Whether the work is at height
- How many rooms, windows or areas are involved
- Any mould that needs treating
- Which sealant suits the joint
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk and we’ll talk you through it.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- The address or postcode of the job
- Roughly how big the job is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, drop us a line at info@mrmastic.co.uk.
Surface by surface
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as that is a job for a joiner.
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.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Do not paint over the silicone
- Keep solvents and bleach off the sealant
- Keep timber frames painted
- Do not aim a pressure washer at the 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.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
What window mastic looks like in Exnaboe
Exnaboe is close to 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. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Around Exnaboe, as everywhere, window mastic is only as good as the preparation behind it.

What else we do in Exnaboe
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. Outdoor work around Exnaboe depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Where the joints are inside, avoid wetting them before we arrive
- Mention any parking rules near the property

FAQs for Exnaboe
Is window mastic in a coastal place like Exnaboe any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Can you do window mastic in Exnaboe?
Yes. We work across all of Scotland, and Exnaboe is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Can new window sealant be painted?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Can you reach windows above the ground floor?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Can tenants book the work?
Yes, but check with your landlord or agent first. Many landlords are glad to have it sorted.
