Sand mastic in Tidebrook, done properly
We work across Tidebrook renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We’re often asked to deal with draughts and rain around sash boxes and modern sealant on a period surround, across period & listed homes, tenement windows and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Tidebrook is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What sand mastic looks like in Tidebrook
With historic houses such as Wadhurst Castle (about 2.3 miles north-east) nearby, there’s older building stock in the area around Tidebrook as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as The Parish Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Wadhurst station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.

Common questions in Tidebrook
Is Tidebrook within the area you cover?
Yes. Tidebrook is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Wadhurst station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will send you a clear quote.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that usually means someone at home.
Do the sealants smell?
Some sealants have a smell while they cure. Opening a window helps.
Can sand mastic be painted?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll talk you through it.
Do you take out the old sealant first?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Ask the planning authority about consent for listed or conservation-area homes
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
DIY sealant or a professional job?
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.
A DIY attempt does not rule out a professional job. We cut it out and start again.
How the visit works
At the end, we look at the finished work together. The work normally takes anything from a few hours to a full day, depending on how many windows, depending on the amount of work. Somewhere as small as Tidebrook, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- 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
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work

Upper-floor windows need access planning. Let us know the floor and we’ll confirm access.
Common problems we fix in Tidebrook
Timber frames move with the seasons. The movement cracks the mastic over time.
Keep an eye out for any of the following:
- Open joints round the window box
- Silicone on a period window that looks wrong
- Tired mastic found when preparing windows for paint
- Gaps round a timber door in stone or brick
For site and facilities teams at buildings such as Uplands Community College, the mastic around its windows and doors needs looking after like any other building’s.
