DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Sand mastic in Clatterford
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include silicone on a period window that looks wrong and tired mastic found when preparing windows for paint, across sash and case windows, period & listed homes and tenement windows.
Around Clatterford, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

What the job involves on each surface
Tenement and terrace windows
Where a building is shared, window work may involve neighbours, so check who is responsible first.
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Why it’s worth doing now in Clatterford
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. Where the frames are in good order, new mastic seals the surround. Around Clatterford, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Signs you need sand mastic in Clatterford
Most of it is simply age. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
The most common problems we see are:
- Weathered mastic on the most exposed windows
- Silicone on a period window that looks wrong
- Gaps round a timber door in stone or brick
- Cement or filler used on old window joints that has cracked
For an older house near a landmark such as Church of St. Nicholas in Castro, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How it works
There’s no need to move everything out, 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 in most cases. Somewhere as small as Clatterford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property
- Mention any tricky access

FAQs for Clatterford
What guarantee comes with sand mastic in Clatterford?
Every job comes with our one-year guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Is Clatterford within the area you cover?
Yes. Clatterford is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can sand mastic be painted?
Sand mastic is normally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

Clatterford homes and the weather
With historic houses such as Carisbrooke Castle (about 0.3 miles east) nearby, there’s older building stock in the area around Clatterford 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as St Thomas of Canterbury Catholic Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
