Windows and doors in Crouch
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Old Soar Manor (about 1 mile south) nearby, there’s older building stock in the area around Crouch as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Borough Green Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Borough Green & Wrotham station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Sand mastic in Crouch, done properly
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on stone surrounds, tenement windows and period & listed homes, and people most often call us about old cement repairs round a window that have failed and draughty sash windows at the surround.
In a village or hamlet like Crouch, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months.

The process
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows. Somewhere like Crouch needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property

When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Sashes that rattle, stick or won’t open
- Decayed frames that need repair
- Broken panes
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think before you book.
Surfaces we seal
- Stone surrounds
- Sash and case windows
- Timber door frames
- Tenement windows
- Brick reveals
- Period & listed homes
DIY versus a professional finish
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 does not work out, we can still put it right.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.

Why it’s worth doing now in Crouch
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Crouch can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
