What happens on the day
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself usually takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. In a small place like Howe Green, access is normally the main thing to plan. 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.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks

How we handle window mastic in Howe Green
A cold draught around a closed window often comes from the frame edge. 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. We work on composite doors, patio & French doors and timber windows & doors, and common reasons people get in touch are mastic that’s falling out in pieces and cracked internal joints between frame and plaster.
Around Howe Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months.

Do you need window mastic in Howe Green?
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Common reasons people contact us include:
- Draughts coming in around windows and doors
- Leaking joints at the ends of sills
- Cracked internal joints between frame and plaster
- Sealant in the wrong colour for the frame
Schools such as The Sandon School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What else we do in Howe Green
Landlord and commercial work in Howe Green
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Wipe condensation off the frames
- Repaint timber before it’s bare
- Make sure the drainage slots are not blocked
- Wash the frames with mild soapy water
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.

Howe Green homes and the weather
Historic houses like Danbury Place (about 1.7 miles north-east) are a reminder that the area around Howe Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Letting a property close to Chelmsford station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of St Andrew, the joint between an old wall and a newer frame is generally the first place rain gets in.

Why it’s worth doing now in Howe Green
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Howe Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
