Window mastic in Birch Green, done properly
Homes in Birch Green have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you’re dealing with draughts coming in around windows and doors and cracked internal joints between frame and plaster, we can put it right, on uPVC windows, timber windows & doors and patio & French doors alike.
Homes in small places like Birch Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What happens if it’s left?
Resealing frames is a short job: it takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Birch Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

How to look after the new joints
After the cure time, these simple habits help:
- Wipe condensation off the frames
- Don’t aim a pressure washer at the joints
- Paint up to the joint, not over it
- Repaint timber before it’s bare
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Quotes for window mastic in Birch Green
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Working hours on commercial sites
- The product the joint needs
- Access and height
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- Whether it has been sealed before
- What the problem is, such as mould, gaps, leaks or cracking
Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or drop us an email with the details.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a morning for a couple of windows and a door and we leave things clean and tidy. Somewhere as small as Birch Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Window mastic in Birch Green: local notes
With historic houses such as Layer Marney Tower (about 1.4 miles south-west) nearby, there’s older building stock in the area around Birch Green as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Birch Church of England Voluntary Aided Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near St Mary's Church, the joint between an old wall and a newer frame is usually the first place rain gets in. If you let a flat or house near Marks Tey station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Your questions about window mastic in Birch Green
Do you work for landlords with property near Marks Tey station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Do you cover Birch Green for window mastic?
Yes, Birch Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Do you work on first-floor windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Condensation trapped between the panes
- A frame that has rotted at the joint
- A door that needs adjusting, rehanging or new seals
If you are not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- uPVC windows
