Portknockie homes and the weather
Portknockie is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Around Portknockie, as everywhere, window mastic is only as good as the preparation behind it. In the older streets around Church Of Scotland, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Portknockie is about 4 miles north-east of Buckie, in Moray. Anywhere in AB56, our applicators can take on window mastic. We cover 58 towns and villages across Moray, large and small. For nearby work, see our Aberdeen page.
All of AB56 is within our area for window mastic, from the main roads to the quietest streets. That includes homes and businesses on High Street, Station Road and Victoria Place and the roads around them.

About our window mastic in Portknockie
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. We work on uPVC windows, timber windows & doors and window sills, and common reasons people get in touch are gaps left after new windows were fitted and rain getting in at the frame or under the sill.
Mastic can only go onto a dry joint, so outside work in Portknockie depends on the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Wash the frames with mild soapy water
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
- Keep paint off silicone joints
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

Can you do window mastic in Portknockie?
Yes. Our work covers the whole of Scotland, and Portknockie is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we’ll give you a clear quote.
When is the sealant fully cured?
Cure times vary by product. We tell you how long to leave it before we go.
Can I do it myself?

Do you have insurance?
Yes. We are fully insured, and we can confirm the details when we quote.

What affects the quote in Portknockie
Every job gets its own quote. These are the things that affect it:
- How many areas need sealing

- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will explain what it covers.
Helping us quote
To make quoting easier, please include:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- Where the property is
- Pictures of the joints, sent by email
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will explain what’s involved and send you a clear quote.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. Outdoor work around Portknockie depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First, we confirm safe access to each frame.
- 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.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

What happens if it’s left?
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, using a product chosen for the frame and wall. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Different surfaces, different methods
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
