Sand mastic for homes and businesses in Netley
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. We work on sash and case windows, tenement windows and stone surrounds, and common reasons people get in touch are gaps where the frame meets the masonry and cement or filler used on old window joints that has cracked.
Houses in smaller places like Netley can stand more in the open than those in a built-up town. That’s hard on the mastic around frames and sills.
Big or small, it’s backed by our one-year guarantee.

Do you need sand mastic in Netley?
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
The problems people usually mention when they call include:
- Weathered mastic on the most exposed windows
- Gaps round a timber door in stone or brick
- Gaps between timber frames and stone or brick
- Mastic dropping out of the joint
For landlords with property near Netley station, any sash windows need sound mastic to keep draughts and rain out.

What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Homes in smaller places like Netley can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

Netley homes and the weather
Netley is within about 1 mile 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. With historic houses such as Medieval Merchant's House (about 3 miles north-west) nearby, there’s older building stock in the area around Netley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Church of St Edward the Confessor, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Netley Abbey Infant School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- How many areas need sealing
- The old material and how stubborn it is
- The type of sealant required
- Mould in or behind the old joints
Leaving a failed joint usually makes the job bigger, not smaller. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.
What we need to know
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints. In a smaller place like Netley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Mention any parking rules near the property

Can I choose the sealant colour?

Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do I need permission for sand mastic on a listed building?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
