Your questions about sand mastic in Belhelvie
Does the coastal weather in Belhelvie affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Dyce station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear price.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we will advise.
What exactly is sand mastic?
A traditional pointing material made from sand and a linseed-oil-based binder, used between timber frames and stone or brick.
How long does the job take?
That depends on how much there is to do, but most jobs take a few hours for a single window, longer for several. We’ll tell you when we quote.
Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in and agree one before work begins.
About our sand mastic in Belhelvie
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on brick reveals, stone surrounds and period & listed homes, and common reasons people get in touch are a silicone bead on a sash window that spoils the look and draughts and rain around sash boxes.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
Every job comes with a one-year guarantee, wherever you are in Aberdeen.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for a single window, longer for several. For a place like Belhelvie, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Advice
Surface by surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Period and listed homes
Period homes look their best with traditional materials.
Why act early in Belhelvie
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a place like Belhelvie, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.
Why book with us
- Over 20 years’ experience
- Any old sealant cut out fully, not covered over
- Approved under the ARBOMaster scheme
- We’re fully insured

What sand mastic looks like in Belhelvie
Belhelvie is close to 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. Aberdeen is known as the Granite City, and granite is hard and dense, so any sealant against it needs clean, sound edges to grip.
In the older streets around Belhelvie North Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Dyce station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
Belhelvie is about 7 miles north of Aberdeen, in Aberdeen. We provide sand mastic to homeowners, landlords and businesses in Belhelvie, as part of our work across Aberdeen. We cover 63 towns and villages across Aberdeen, from the larger towns to small villages. Aberdeen is on our list too, around 7 miles away.

What’s near Belhelvie

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep sills and gutters clear so water drains away
- Ask the planning authority about consent for listed or conservation-area homes
- Check the mastic when you check the paintwork
- Renew mastic before redecorating the windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
We work for letting agents and landlords as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Honest limits
A few problems are outside what sealant work can do:
- Damaged stone surrounds
- Sash cords, weights and draught-proofing of the sashes
- Cracked or broken glass
