New Pound homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Old Soar Manor (about 1.9 miles west) are a reminder that the area around New Pound has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you live in an older home near St Lawrence's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Mereworth Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

About our sand mastic in New Pound
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we will talk through which suits your home. We work on sash and case windows, stone surrounds and tenement windows, and people most often call us about silicone on a period window that looks wrong and crumbling sand mastic round a window.
In a village or hamlet like New Pound, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes as standard.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

How to look after the new joints
So the new joints stay in good condition:
- Don’t run silicone over sand mastic
- Do not paint over the new mastic
- Go gently near the mastic when preparing windows
- Ask the planning authority about consent for listed or conservation-area homes
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Decisions on consent for listed homes
- Sashes that need overhauling
- Putty and glazing repairs
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.
Joints and surfaces we work on

Landlords, agents and businesses in New Pound
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Different surfaces, different methods
Tenement and terrace windows
Where a building is shared, window work may involve neighbours so it’s worth checking responsibilities.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
New Pound questions
Can you help a landlord with a rental near Wateringbury station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is New Pound in your area for sand mastic?

What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Where do you work from?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours per window, depending on the condition of the joints. Somewhere like New Pound 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.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Mention any parking rules near the property

- Cement or filler used on old window joints that has cracked
- Cracked mastic round a front door frame
- Draughts and rain around sash boxes
- Crumbling sand mastic round a window
For landlords with property near Wateringbury station, any sash windows need sound mastic to keep draughts and rain out.
