About our window mastic in South Weald
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before work begins. Just phone 0345 464 0079 or email us and tell us how many frames there are and how they’re reached. Common call-outs are for gaps left after new windows were fitted and white mastic on grey or black frames, on patio & French doors, uPVC windows and aluminium frames.
Homes in small places like South Weald 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.
Each job carries a 12-month guarantee, large or small.

What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. We’ll point out any rot we find, as that is a job for a joiner.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Quotes for window mastic in South Weald
You’ll get a clear quote before work begins. It’s based on:
- Whether there’s mould to deal with
- The number of rooms or windows

What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Where the property is
- The rough size of the job
- The problem you’ve noticed
- The type of property
We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a morning for a couple of windows and a door, and the area is left clean. Somewhere like South Weald needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Advice
South Weald: your questions answered
Can you help a landlord with a rental near Brentwood station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Can you do window mastic in South Weald?
Yes. Our work covers London and the South East, and South Weald is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Do you have sealant for grey or black windows?
Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
How long does it take to reseal the windows on a house?
Allow most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.
Can you seal over the old sealant?
No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What happens if it’s left?
The work is quick compared with the damage it prevents: it takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Where a wall is exposed, as many are in small places like South Weald, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What you get with us
- 20+ years of sealant experience

What we’re called out for in South Weald
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Keep an eye out for any of the following:
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Hard, cracked sealant around windows
- Rushed sealant from a window installation
Rented homes near Brentwood station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What window mastic looks like in South Weald
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 Hare Hall (about 3.6 miles south-west) are a reminder that the area around South Weald 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.
If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Holly Trees Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
