Bucks Green: your questions answered
Do you work for landlords with property near Christs Hospital station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Will you come out to Bucks Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.

Most jobs take a few hours for a single window, longer for several. Your quote will say how long we expect yours to take.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Do I need permission for sand mastic on a listed building?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.
Is the work guaranteed?
You get our one-year guarantee to all our work.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Sand mastic for homes and businesses in Bucks Green
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We are often asked to deal with weathered mastic on the most exposed windows and mastic round period door frames that has failed, across period & listed homes, timber door frames and stone surrounds.
Homes in small places like Bucks Green often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What else we do in Bucks Green
What sand mastic looks like in Bucks Green
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Christs Hospital station, any sash windows need sound mastic to keep draughts and rain out.

Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
Do you need sand mastic in Bucks Green?
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.
It’s worth asking for a quote if you see:
- Cement or filler used on old window joints that has cracked
- Window mastic to renew ahead of painting
- Gaps where the frame meets the masonry
- Modern sealant on a period surround
If you look after a building such as Pennthorpe School, the mastic around its windows and doors needs looking after like any other building’s.

Quotes for sand mastic in Bucks Green
We do not publish a price list, because no two jobs are the same. The quote depends on:
- How easy the joints are to reach
- Any working-time requirements on site
- Mould in or behind the old joints
- The type of sealant required
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
There’s no need for technical detail. Just tell us:
- What’s wrong with the joints now
- A few pictures by email, if you can
- The type of property
- How we’d reach the joints
Getting a quote is simple: let us know what needs doing and where. Photos by email help us understand the job, and we’ll come back to you with a quote.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Keep modern sealant off the mastic
- Leave the new mastic unpainted
- Go gently near the mastic when preparing windows
- Have rotten timber repaired before new mastic goes in
Don’t touch or press the mastic while it hardens. It forms a skin fairly soon but needs longer to fully harden.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
What we do, step by step
We keep the work tidy and contained to the joints we are treating, so you can carry on as normal. The job normally takes a few hours per window, depending on the condition of the joints, and we explain the cure time before we leave. In a small place like Bucks Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
How to get a quote
Every job is quoted individually. Simply call 0345 464 0079 or send us an email and describe the job, and pictures are welcome.
