About our sand mastic in Wellhouse
Traditional burnt sand mastic that sits naturally against stone and brick. It’s a good fit for period properties, where modern sealant can look out of place. If you are dealing with wind and rain getting in round a sash window and open joints round the window box, we can help.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Do you need sand mastic in Wellhouse?
Rain on the window surround works into any crack and loosens it further. Exposed elevations usually fail first.
The most common problems we see are:
- Open joints round the window box
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
- Mastic round period door frames that has failed
For an older house near a landmark such as Saint Benedict's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic in Wellhouse: local notes
With historic houses such as Provand's Lordship (about 4 miles west) nearby, there’s older building stock in the area around Wellhouse as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Wellhouse is in the west of Scotland, which is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
For landlords with property near Garrowhill station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Bannerman High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What affects the quote in Wellhouse
You’ll get a clear quote before any work starts. It takes into account:
- Working hours on commercial sites
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- The address or postcode of the job
- What’s wrong with the joints now
- A few pictures by email, if you can
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved and send you a clear quote.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Clear gutters so water doesn’t pour onto the windows
- Avoid patching sand mastic with silicone
- Leave the new mastic unpainted
- Find out about consent before window work on a listed home
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. Somewhere like Wellhouse may be a longer drive, and the journey is planned ahead. 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.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Your questions about sand mastic in Wellhouse
Can you help a landlord with a rental near Garrowhill station?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.

What is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
Is sand mastic better than silicone for my windows?
We’ll talk it through with you. Sand mastic suits many period homes, and modern sealants suit newer frames.
