Looking after it afterwards
To keep the joints looking good and working properly:
- Avoid patching sand mastic with silicone
- Sort the mastic before the decorators arrive
- Get any rot dealt with first
- Ask us before painting near the mastic
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.

Signs you need sand mastic in Newmains
Sand mastic slowly weathers. It dries out, cracks and loses its grip from the frame or the masonry.
The problems people usually mention when they call include:
- Old sand mastic that has cracked, crumbled or fallen out
- Cracked mastic round a front door frame
- Mastic worn away on windows facing the weather
- Modern sealant on a period surround
Rented homes near Cleland station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.
Before you book anyone

- What happens if they find a problem under the old sealant
- Which sealant they’ll use, and why
- How much experience the applicator has
Why act early in Newmains
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Around Newmains, water from a failed joint in an older stone home can soak into timber and plaster.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Newmains homes and the weather
With historic houses such as Cambusnethan House (about 3.3 miles south-west) nearby, there’s older building stock in the area around Newmains as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Coltness Memorial Church include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in. For site and facilities teams at buildings such as Coltness High School, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We check each window surround and the condition of the joint.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Mention if the joints have been sealed before
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
