Portmahomack homes and the weather
Portmahomack 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 older windows and doors, especially on the side facing the sea. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Whether the job is in Portmahomack itself or nearby, the right material for each joint matters as much as a neat finish.

FAQs for Portmahomack
Does the coastal weather in Portmahomack 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.
Do you cover Portmahomack for sand mastic?
Yes, Portmahomack is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
What’s sand mastic made of?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Can I choose the sealant colour?
Normally, yes. Sealants come in white, clear, grey and other colours, and we will agree it with you first.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- The size of the job
- When we can work, for business premises
- Which sealant suits the joint
- Whether the work is at height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
Before you ask for a quote, have a think about:
- The address or postcode of the job
- Whether it has been sealed before
- Access, such as stairs, a lift or height
- The type of property
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
The process
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. Outdoor work around Portmahomack depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- Mention any tricky access

Why act early in Portmahomack
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. In a place like Portmahomack, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.
