Sand mastic for homes and businesses in Hillhouse
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. If you’re dealing with silicone on a period window that looks wrong and cement or filler used on old window joints that has cracked, we can put it right, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Hillhouse depends on the weather. Let us know about access to every frame, including any upstairs.
Whatever the size of the job, it’s backed by our 12-month guarantee in Hillhouse and across South Lanarkshire.

Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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 else we do in Hillhouse
The process
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to a full day, depending on how many windows for a typical job. Outside jobs in Hillhouse need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints
- Let us know about parking restrictions

What we are called out for in Hillhouse

The problems people normally mention when they call are:
- Modern sealant on a period surround
- Cracked mastic round a front door frame
- Old sand mastic that has cracked, crumbled or fallen out
- Draughts and rain around sash boxes
For landlords with property near Hamilton West station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Common questions in Hillhouse
Do you work for landlords with property near Hamilton West station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Do you cover Hillhouse for sand mastic?
Yes, Hillhouse is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing, and we’ll send you a clear quote.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
How long does sand mastic take to go off?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.
Is sand mastic better than silicone for my windows?
Sand mastic generally suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Do you guarantee sand mastic work?
Our 12-month guarantee applies to all our work.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.

- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Frames and glazing around Hillhouse
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.
Schools such as John Ogilvie High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

A little further out are David Livingstone Centre (2 miles north) and Calderwood Castle (1.8 miles west). The countryside around Hillhouse includes Cathkin Braes and Strathclyde Loch.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid patching sand mastic with silicone
- Renew mastic before redecorating the windows
- Get any rot dealt with first
- Ask us before painting near the mastic
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Surface by surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
When it isn’t the sealant
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Sashes that rattle, stick or won’t open
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.
