Window mastic for homes and businesses in Cowey Green
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. Typical jobs include draughts coming in around windows and doors and rushed sealant from a window installation, across patio & French doors, aluminium frames and window sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Cowey Green is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You get a 12-month guarantee, the same in Cowey Green as everywhere else we work.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Don’t use solvent cleaners on the joint
- Check the mastic once a year
- Keep paint off silicone joints
- Wash the frames with mild soapy water
Try not to touch the new joint while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Questions from Cowey Green
Will you come out to Cowey Green?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Cowey Green in your area for window mastic?
Yes. We work across London and the South East, and Cowey Green is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear price.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Can you do upstairs windows?
Yes, if safe access is possible. For high or awkward windows, we’ll tell you what access is needed.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can you do the inside joint as well?
Yes. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
Can I do it myself?
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.
Do the sealants smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Landlord and commercial work in Cowey Green
For anyone letting property in or around Cowey Green, jobs at different addresses can go on one quote. Send us the addresses and the work at each, and pictures by email help.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Around Cowey Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

Cowey Green homes and the weather
Rainfall in the South East is lower than in much 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 Castle House (about 4.5 miles north-west) nearby, there’s older building stock in the area around Cowey Green 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.
In the older streets around Church of St George, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Schools such as St George's Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Common problems we fix in Cowey Green
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. That’s what backing rod is for.
Most people get in touch when they notice something like this:
- Cracked internal joints between frame and plaster
- Cracked sealant at the sill ends
- Rushed sealant from a window installation
- Mastic that has split away from the wall
For landlords with property near Great Bentley station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
