If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Mill Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

About our window mastic in Mill Green
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We’re often asked to deal with cracked sealant at the sill ends and mastic that has split away from the wall, on timber windows & doors, aluminium frames and window sills.
Somewhere as small as Mill Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, large or small.

Window mastic in Mill Green: local notes
Historic houses like Ingatestone Hall (about 1.9 miles south-east) are a reminder that the area around Mill Green 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Ingatestone Infant School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Use gentle cleaners on frames and sealant
- Don’t paint over the silicone
- Keep timber frames painted
- Air rooms to keep condensation down around windows
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Leaks normally 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.
Quotes for window mastic in Mill Green
Your quote is based on your job. We look at:
- Mould in or behind the old joints
- When we can work, for business premises
- The number of rooms or windows

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Access, such as stairs, a lift or height

Questions from Mill Green
Is Mill Green in your area for window mastic?
Yes. Our work covers London and the South East, and Mill Green is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
I let a flat near Ingatestone station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Are you insured?
Yes. Mr Mastic is fully insured.
Will new mastic stop draughts?
Often, yes. The gap between frame and wall is a common source of draughts, and resealing inside and out closes it.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- A sash or casement that will not close properly
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Joints and surfaces we work on
- Aluminium frames
- Window sills

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
What happens on the day
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job usually takes most of a day for a typical house, less for a few frames, and we tell you how long to leave it before we go. In a small place like Mill Green, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Keep children and pets away from the work area
- On commercial sites, let us know about site rules
- Tell us about any previous sealing or DIY attempts

Advice
What we are called out for in Mill Green
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Any of these means the joints need attention:
- Cracked or shrunken mastic around the frame
- Gaps where the sill meets the wall
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
Rented homes near Ingatestone station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
