Inverinate Window Mastic
Window and door frames in Inverinate need attention? We remove the old material, prepare the joints and seal them properly.
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
When something else is needed
It helps to know what we cannot do:
- A frame that has rotted at the joint
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.
Joints and surfaces we work on
- Composite doors
- Aluminium frames
- Window sills
- Timber windows & doors

- Patio & French doors
Window mastic in Inverinate, done properly
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. We work on aluminium frames, patio & French doors and uPVC windows, and the jobs we see most are untidy mastic left by window fitters and water coming in at the bottom corners of a door.
Mastic can only go onto a dry joint, so outside work in Inverinate depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Every job is covered by a one-year guarantee, wherever you are in Highland.

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 check before we reseal.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- When we can work, for business premises
- Whether there’s mould to deal with
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Any previous sealing or DIY work
- Where the job is, and your postcode
- Roughly how big the job is
- Any access issues, like height or stairs
Every job is quoted individually, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details and send pictures if you have them.
What window mastic looks like in Inverinate
Inverinate 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. 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.
If you live in an older home near Kintail Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Inverinate is in Highland. From the centre of Inverinate to the outskirts, we cover window mastic for every kind of property. Across Highland, we cover 253 places, Inverinate among them.
All of IV40 is covered for window mastic. We also cover the places around Inverinate: Shiel Bridge (2 miles south), Dornie (4 miles north-west), Bundalloch (5 miles north-west), Carndu (5 miles north-west) and Glen More (6 miles west). If you are somewhere remote, a little more planning is needed.
Landmarks near Inverinate
A little further out are Eilean Donan Castle (4.2 miles north-west). The countryside around Inverinate includes Loch Shiel and Sgùrr an t-Searraich.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Your questions about window mastic in Inverinate
Will you come out to Inverinate?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Does the coastal weather in Inverinate affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
When is the sealant fully cured?
It depends on the product. We tell you how long to leave it before we go.
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.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear.
Common problems we fix in Inverinate
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Common reasons people contact us include:
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
Around Inverinate, as everywhere, window mastic is only as good as the preparation behind it.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- What the cure time is
- Whether you can choose the colour
- Whether the sealant suits the joint
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Before we arrive
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Tell us if parking is tricky
