How we handle window mastic in Newney Green
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on composite doors, uPVC windows and window sills, and people most often call us about rain getting in at the frame or under the sill and sealant in the wrong colour for the frame.
Somewhere as small as Newney Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

When to call us in Newney Green
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
Most people get in touch when they notice something like this:
- A bead that does not match the frame
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
If you let a flat or house near Chelmsford station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Questions to ask before you book
- Who does the work, and how experienced they are

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.

How the job changes by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Composite doors
A composite door generally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Common questions in Newney Green
Do you cover Newney Green for window mastic?
Yes. Our work covers London and the South East, and Newney Green is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
I let a flat near Chelmsford station. Can you help?

Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.
Does the work come with a guarantee?
Yes. Every job comes with our 12-month guarantee, and we are fully insured.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Are you insured?

Newney Green homes and the weather
With historic houses such as Hylands (about 2.7 miles south-east) nearby, there’s older building stock in the area around Newney 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. 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.
Schools such as Hylands School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Michael and All Angels, the joint between an old wall and a newer frame is generally the first place rain gets in.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How it works
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a handful of frames, longer for a whole house. Somewhere like Newney Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear the area around the work
- Keep children and pets away from the work area

Advice
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Rotten timber, which needs a joiner first
- A sash or casement that will not close properly
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Timber windows & doors
- Aluminium frames
- Window sills
- Composite doors
- uPVC windows

Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Around Newney Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
