Window mastic in Portmahomack, done properly
Every window and door frame has a gap around it, and mastic is what closes it. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We are often asked to deal with mastic that’s falling out in pieces and gaps where the sill meets the wall, across timber windows & doors, window sills and patio & French doors.
Mastic can only go onto a dry joint, so outside work in Portmahomack depends on the weather. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Can I do it myself?
Some jobs are best left to a professional: 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’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Portmahomack: your questions answered
Can you do window mastic in Portmahomack?
Yes. Our work covers the whole of Scotland, and Portmahomack is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Will you come out to Portmahomack?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Should I try DIY first?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you do commercial work?
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.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can new window sealant be painted?
Not normally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Frames and glazing around Portmahomack
Portmahomack is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For jobs in and around Portmahomack, choosing the right material for each joint is as important as a tidy finish.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Keep timber frames painted
- Make sure the drainage slots are not blocked
- Don’t use solvent cleaners on the joint
- Look round the frames every year or so
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
Why deal with it now?
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What we cannot put right
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
- Draughts through the window seals rather than the frame
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.
Joints and surfaces we work on

When to call us in Portmahomack
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
The problems people normally mention when they call include:
- A bead that does not match the frame
- Draughty joints inside around the window
- Water coming in at the bottom corners of a door
- Black, perished sealant on frames
In and around Portmahomack, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How it works
Before we leave, we go over the finished joints with you. 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. For a place like Portmahomack, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height
