Window & door mastic in High Easter, Essex
Window and door frames in High Easter need attention? We remove the old material, prepare the joints and seal them properly.
- White mastic on grey or black frames
- Draughts coming in around windows and doors
- Mastic that is falling out in pieces
Window mastic in High Easter
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you are dealing with cracked internal joints between frame and plaster and mastic that’s falling out in pieces, we can help.
Somewhere as small as High Easter, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

When something else is needed
To be straight with you, some problems need a different trade:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first

High Easter homes and the weather
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.
For an older house near a landmark such as Parish Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Common problems we fix in High Easter
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, leaving a hairline gap down one side.
Look out for any of the following:
- A bead that does not match the frame
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
- Old mastic that has gone black or come away
Around High Easter, as everywhere, window mastic is only as good as the preparation behind it.

Is window mastic in High Easter guaranteed?

Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Will resealing my frames help with draughts?
It will if the frame joint is the problem. We check where the draught is before any work starts.
How long should I leave it?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Aftercare tips
A little care helps the new joints last. We recommend:
- Avoid harsh chemicals near the mastic
- Use gentle cleaners on frames and sealant
- Keep jet washers away from the mastic
- Keep paint off silicone joints
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. Expect the work to take a morning for a couple of windows and a door. Somewhere as small as High Easter, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Move anything stored near the joints

Related advice
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, 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 need the right product, the right access and the right method.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.

You’ll get a clear quote before any work starts. It takes into account:
