How we handle sand mastic in North Baddesley
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. Common call-outs are for failed mastic on an exposed elevation and gaps round a timber door in stone or brick, on brick reveals, timber door frames and period & listed homes.
Homes around North Baddesley range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Our work is backed for twelve months.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Clear gutters so water does not pour onto the windows
- Check with your local planning authority if your home is listed
- Check the mastic when you check the paintwork
- Go gently near the mastic when preparing windows
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
What sealant work cannot fix
A few problems are outside what sealant work can do:
- Whether work needs listed building consent
- Sashes that need overhauling
- Masonry that needs repairing

What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before we start. The work generally takes a few hours for a single window, longer for several. In a smaller place like North Baddesley, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- 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 any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Clear the area around the work

Advice
Why act early in North Baddesley
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new mastic stays put. In a smaller place like North Baddesley, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

What sand mastic looks like in North Baddesley
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like South Stoneham House (about 4.1 miles south-east) are a reminder that the area around North Baddesley has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Rented homes near Romsey station change hands often, and any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as North Baddesley Junior School, the mastic around its windows and doors needs looking after like any other building’s.

What else we do in North Baddesley
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
How we quote for sand mastic

Do I need permission for sand mastic on a listed building?
Checking first is sensible. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
Do I need to be at home?

Is the work guaranteed?
Our one-year guarantee covers every job, sand mastic included.
What exactly is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Can I do it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
