What we’re called out for in Hillswick
Water runs down the glass onto the sill, 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.
Signs it’s time to call us include:
- Cracked or shrunken mastic around the frame
- Black, perished sealant on frames
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
In and around Hillswick, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

About our window mastic in Hillswick
Homes in Hillswick have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on patio & French doors, composite doors and uPVC windows, and common reasons people get in touch are untidy mastic left by window fitters and black, perished sealant on frames.
In and around a place like Hillswick, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.

What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Aftercare tips
To keep the joints looking good and working properly:
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
- Keep solvents and bleach off the sealant
- Wipe condensation off the frames
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

What happens on the day
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. Outside jobs in Hillswick 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.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- For business premises, tell us about site rules or sign-in

Advice
Your questions about window mastic in Hillswick
Is window mastic in a coastal place like Hillswick any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Is Hillswick in your area for window mastic?
Yes. We work across all of Scotland, and Hillswick is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we’ll give you a clear price.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Can you match the sealant to my frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Can you do upstairs windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Will new mastic stop draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Why deal with it now?
Draughts and leaks don’t always mean new windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we will say so. Around Hillswick, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas

When it is not the sealant
We will always be straight with you, so here’s what sealant can’t fix:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- A frame that has rotted at the joint
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly.

What affects the quote in Hillswick
Your quote is based on your job. We take into account:
- Whether there’s mould to deal with
- How much there is to do
- The number of rooms or windows
- Whether the work is at height
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- Whether it has been sealed before
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work before giving you a price.
Windows and doors in Hillswick
Hillswick is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
In the older streets around Northmavine Parish Church and Churchyard, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Hillswick is in the Shetland Islands. Hillswick gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a one-year guarantee. Our area takes in 63 places across the Shetland Islands, large and small.
