Window mastic for homes and businesses in Mindenhurst
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you’re dealing with water coming in at the bottom corners of a door and mastic that has split away from the wall, we can help, on timber windows & doors, window sills and aluminium frames alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Mindenhurst is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You get a one-year guarantee, the same in Mindenhurst as everywhere else we work.

The process
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere like Mindenhurst 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.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Your questions about window mastic in Mindenhurst
Is Mindenhurst within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Mindenhurst for window mastic?
Yes, Mindenhurst is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Can you reach windows above the ground floor?
Normally, yes. We plan safe access before the job.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Keeping the joints in good condition
Aftercare is simple:
- Use gentle cleaners on frames and sealant
- Clear any debris from frame drain holes
- Keep solvents and bleach off the sealant
- Repaint timber before it’s bare
Keep the new mastic undisturbed while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
How we quote for window mastic
There’s no set price list. The quote depends on:
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- The type of sealant required
- The amount of work
Doing several joints on one visit is usually more efficient than separate visits. We will send you a clear quote for the lot.
What we need to know
Photos by email are helpful but not essential. Please mention:
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
- Any previous sealing or DIY work
- Where the property is
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Older cottages and farmhouses around Mindenhurst can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
