Common questions in Aird
I let a flat near Stranraer station. Can you help?
Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is sand mastic in a coastal place like Aird any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you guarantee sand mastic work?
Our 12-month guarantee applies on every job.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
What do you need from me for a quote?
Just the basics: where it is, what you’ve noticed and how we reach it. Then send an email to info@mrmastic.co.uk.
Do you offer different sealant colours?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before work begins.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What exactly 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.
About our sand mastic in Aird
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. If you are dealing with a silicone bead on a sash window that spoils the look and wind and rain getting in round a sash window, we can put it right.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Every job is covered by our one-year guarantee, wherever you are in Dumfries and Galloway.

- If it’s domestic, commercial or a hotel

Why act early in Aird
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. In an older home around Aird, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

How it works
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Outside jobs in Aird need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- 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.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Clear the area around the work
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
How to get a quote
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
Advice
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What we’re called out for in Aird
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Any of these means the joints need attention:
- Gaps round a timber door in stone or brick
- Mastic dropping out of the joint
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
For an older house near a landmark such as Old Parish Church and Burial-ground, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What to look for in a quote
- Who does the work, and how experienced they are
- Is VAT in the price?
- Whether all the old sealant comes out first
- How hidden problems are handled
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
- Renew mastic before redecorating the windows
- Keep modern sealant off the mastic
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What sand mastic looks like in Aird
Aird is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. The west of Scotland is wetter than the east, which means the mastic around older windows and doors has to cope with a lot of rain.
Letting a property close to Stranraer station? Then any sash windows need sound mastic to keep draughts and rain out.
