About our sand mastic in Portknockie
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you are dealing with mastic dropping out of the joint and weathered mastic on the most exposed windows, we can put it right.
Outdoor sealant needs a dry surface, so window work around Portknockie is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
Whatever the size of the job, it’s backed by our one-year guarantee.

Portknockie questions
Does the coastal weather in Portknockie affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Will you come out to Portknockie?
Yes. Portknockie is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Where are you based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Can you replace silicone on a period window with sand mastic?
Usually, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply email us at info@mrmastic.co.uk.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to a full day, depending on how many windows and we leave things clean and tidy. For a place like Portknockie, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.
How to prepare
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints
- For business premises, tell us about site rules or sign-in

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Portknockie homes and the weather
Portknockie 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 is hard on the mastic around older windows and doors, especially on the side facing the sea. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
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.

Signs you need sand mastic in Portknockie
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
These are the problems we are asked about most:
- A silicone bead on a sash window that spoils the look
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- Gaps round a timber door in stone or brick
In and around Portknockie, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Plan mastic work ahead of painting
- Don’t run silicone over sand mastic
- Ask a joiner to look at soft timber first
- Find out about consent before window work on a listed home
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
Why it’s worth doing now in Portknockie
An open joint round the frame lets weather in. Water can get to the frame and the masonry, so dealing with it now protects both. In an older home around Portknockie, damp from a failed joint can get into timber and plaster.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first.
