Window mastic in Lane End
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. We work on timber windows & doors, aluminium frames and patio & French doors, and the jobs we see most are white mastic on grey or black frames and old mastic that has gone black or come away.
Outdoor sealant needs dry, clean surfaces, so work on frames around Lane End is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

What affects the quote in Lane End
We do not publish a price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Working hours on commercial sites
- Access and height
- Any mould that needs treating
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- Whether it has been sealed before
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, ring 0345 464 0079 or send us an email.
What we can’t put right
To be straight with you, there are a few things sealant will not fix:
- Draughts through the window seals rather than the frame
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly.

What happens if it’s left?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we will say so. Older cottages and farmhouses around Lane End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Is Lane End within the area you cover?
Yes, Lane End is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you remove the old sealant?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.

What information do you need?
Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
Can you do upstairs windows?
Yes, if safe access is possible. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Paint up to the joint, not over it
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Don’t aim a pressure washer at the joints
Silicone cannot generally be painted, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

How the job changes by surface
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.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
