About our sand mastic in New Alyth
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We work on sash and case windows, tenement windows and period & listed homes, and the jobs we see most are draughty sash windows at the surround and mastic worn away on windows facing the weather.
Outdoor sealant needs a dry surface, so window work around New Alyth is planned around the weather. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of sand mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- Any working-time requirements on site
- Whether there’s mould to deal with
- The product the joint needs
- Whether the work is at height
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, drop us a line at info@mrmastic.co.uk and we will give you an honest view and a quote.

What the job involves on each surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
Do you need sand mastic in New Alyth?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Look out for these signs:
- Window mastic to renew ahead of painting
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
- Old cement repairs round a window that have failed
For an older house near a landmark such as St Ninian's Episcopal Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- How the joint is cleaned and prepared
- The length of the guarantee
- What product goes in the joint
- Is VAT in the price?
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours per window, depending on the condition of the joints. Somewhere like New Alyth 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.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

Aftercare tips
After the cure time, these simple habits help:
- Ask the planning authority about consent for listed or conservation-area homes
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Look over the window mastic once a year
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens as more mastic falls out.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Timber that has rotted
- Putty and glazing repairs
- Damaged stone surrounds
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

Frames and glazing around New Alyth
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

Do you cover smaller places like New Alyth?

What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.
Which is right for my windows, sand mastic or modern sealant?
We’ll help you decide. Sand mastic suits many period homes, and modern sealants suit newer frames.
