How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Make sure the drainage slots aren’t blocked
- Paint up to the joint, not over it
- Check the mastic once a year
- Keep paint and stain on wooden frames in good order
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
About our window mastic in Doddinghurst
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. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. If you are dealing with black, perished sealant on frames and white mastic on grey or black frames, we can put it right.
Homes in small places like Doddinghurst often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the job changes by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
For landlords and businesses
Landlords and agents in Doddinghurst can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Signs you need window mastic in Doddinghurst
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
Signs it’s time to call us include:
- Mastic that has split away from the wall
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
- Water coming in at the bottom corners of a door
For an older house near a landmark such as Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Doddinghurst
Do you work for landlords with property near Shenfield station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
Will you come out to Doddinghurst?
Yes. Doddinghurst is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that normally means someone at home.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Can you do the inside joint as well?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is the new sealant paintable?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before work begins.

Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.

Window mastic in Doddinghurst: local notes
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Ingatestone Hall (about 3.8 miles east) are a reminder that the area around Doddinghurst 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.
For landlords with property near Shenfield station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Doddinghurst Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
