Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
About our window mastic in Rush Green
Around Rush Green we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, composite doors and timber windows & doors, and people most often call us about old mastic that has gone black or come away and cracked sealant at the sill ends.
Homes in small places like Rush Green 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.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How we quote for window mastic
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- How many areas need sealing
- Which sealant suits the joint
- Whether the work is at height
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.
What to tell us for a quote
To make quoting easier, please include:
- Any access issues, like height or stairs
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid blasting the frames with a pressure washer
- Do not paint over the silicone
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
Silicone can’t normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What window mastic looks like in Rush Green
With historic houses such as Ickenham Hall (about 3.2 miles east) nearby, there’s older building stock in the area around Rush Green as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
In the older streets around St Francis, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Denham Village School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Do you need window mastic in Rush Green?
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
People usually contact us after spotting something like this:
- Draughts coming in around windows and doors
- Gaps where the sill meets the wall
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
If you let a flat or house near Denham Golf Club station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

FAQs for Rush Green
Can you do window mastic in Rush Green?
Yes, Rush Green is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Is Rush Green within the area you cover?
Yes. Rush Green is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you seal the gap between the frame and the plaster indoors?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
What do you need from me for a quote?
Let us know what needs doing and where, plus pictures if you have them. If we need more, we’ll ask.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
What happens if it’s left?
Resealing frames is a short job: it takes a few hours for a few frames, or a day or more for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Older cottages and farmhouses around Rush Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
