Why deal with it now?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall, so dealing with it now protects both. Older cottages and farmhouses around Muddles Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

- The product the joint needs

Different surfaces, different methods
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It generally takes a few hours for a single window, longer for several. Somewhere as small as Muddles Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access

Sand mastic in Muddles Green: local notes
With historic houses such as Horselunges Manor (about 2.2 miles south-east) nearby, there’s older building stock in the area around Muddles Green 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you let a flat or house near Berwick (Sussex) station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Chiddingly Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

A little further out are Sussex Farm Museum (2.8 miles north-east) and Hellingly Hospital Railway (2.6 miles east). Not far away are Selwyns Wood.
Should I try it myself first?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Common problems we fix in Muddles Green
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Keep an eye out for any of the following:
- Draughts and rain around sash boxes
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
In the older streets around The Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
