Sand mastic in Godden Green
Across Godden Green, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. We work on stone surrounds, brick reveals and timber door frames, and common reasons people get in touch are draughts and rain around sash boxes and window mastic to renew ahead of painting.
Somewhere as small as Godden Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Your job is guaranteed for a year, as with all our work.

Can you replace silicone on a period window with sand mastic?
Often, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Is the work guaranteed?
There’s a 12-month guarantee on every job.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings. The product needed can limit the range.
Is there any odour?
Some sealants have a smell while they cure, but it fades. Ventilation helps.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Why act early in Godden Green
New sash windows are a major, costly change, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Older cottages and farmhouses around Godden Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why book with us
- A 12-month guarantee on all work
- Old sealant always removed completely
- Anti-fungal sanitary silicone in wet areas

Surface by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. Sand mastic is shaped by hand to suit.
Sash and case windows
Sash windows are where we do most sand mastic work. We renew the mastic round each box.
Honest limits
New sealant cannot fix everything, and we will tell you before work begins. Sealant won’t put right:
- Masonry that needs repairing
- Timber that has rotted
- Sashes that need overhauling
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Sash and case windows
- Timber door frames

Windows and doors in Godden Green
Historic houses like Knole House (about 1 mile south-west) are a reminder that the area around Godden Green 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. 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.
If you look after a building such as Sevenoaks Preparatory School, larger buildings have plenty of frames, and the mastic around each one ages. Knole House, about 1 mile south-west, is one of the historic houses in the wider area around Godden Green.

How it works
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints in most cases. Somewhere like Godden Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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 isn’t too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any sign-in or site rules at work premises

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
