Sand mastic for homes and businesses in Sgalpaigh
If your home is listed or in a conservation area, check with your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We’re often asked to deal with cement or filler used on old window joints that has cracked and mastic that needs renewing before redecorating, across timber door frames, period & listed homes and sash and case windows.
Mastic can only go onto a dry joint, so outside work in Sgalpaigh depends on the weather. Let us know about access to every frame, including any upstairs.
Big or small, it’s backed by our one-year guarantee in Sgalpaigh and across Na h-Eileanan Siar.

Sgalpaigh homes and the weather
Sgalpaigh is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Around Sgalpaigh, as everywhere, sand mastic is only as good as the preparation behind it.

What affects the quote in Sgalpaigh
The quote reflects the job in front of us. We look at:

- How easy the joints are to reach
- The number and length of the joints
- Whether there’s mould to deal with
What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before we start.

There’s no need for technical detail. Just tell us:
- The problem you’ve noticed
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- How we’d reach the joints
We quote each job on its own, so start by telling us what you need. Simply send an email to info@mrmastic.co.uk and describe the job, and photos are welcome.
What happens on the day
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before any work begins. The work usually takes anything from a few hours to a full day, depending on how many windows. Somewhere like Sgalpaigh may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- 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
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Tell us about access, such as stairs, a lift or high-level joints

What the job involves on each surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It suits older brickwork.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Why it’s worth doing now in Sgalpaigh
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a place like Sgalpaigh, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- Old sealant always removed completely
- Neat joints and a tidy finish
- One-year guarantee on every job
- Fully insured

- Mastic round period door frames that has failed
- Mastic that needs renewing before redecorating
- Modern sealant on a period surround
Whether the job is in Sgalpaigh itself or nearby, the right material for each joint matters as much as a neat finish.

Looking after it afterwards
So the new joints stay in good condition:
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Leave the new mastic unpainted
- Make sure water runs off the sill
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.
