About our window mastic in Mousehill
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on uPVC windows, timber windows & doors and patio & French doors, and common reasons people get in touch are rain getting in at the frame or under the sill and gaps between the frame and the inside reveal.
Homes in small places like Mousehill 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.
All our work comes with our one-year guarantee, wherever you are in Surrey.

What we do, step by step
The work is kept neat and contained to the area we are working on. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Somewhere like Mousehill 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.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Related advice
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Do you need window mastic in Mousehill?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
Keep an eye out for these signs:
- A bead that does not match the frame
- Gaps left after new windows were fitted
- Damp patches on the reveal after heavy rain
- Draughts coming in around windows and doors
Letting a property close to Milford (Surrey) station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
What your quote should include
- What happens if the job turns out different
- Is VAT in the price?
- How the joint is cleaned and prepared

What we can’t put right
A few problems are outside what sealant work can do:
- Penetrating damp from a failed cavity tray or render
- Worn gaskets, brush seals or a door that has dropped
- A frame that has rotted at the joint

Mousehill questions
Can you help a landlord with a rental near Milford (Surrey) station?
Yes. We work for landlords and agents as well as homeowners. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Is Mousehill in your area for window mastic?
Yes. Our work covers London and the South East, and Mousehill is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Do you remove the old sealant?
Yes, every time. New silicone does not stick to old silicone, so the joint is cleaned back first.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Can new window sealant be painted?
Not usually, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
How long does it take to reseal the windows on a house?
A few frames take a few hours. We confirm the timing with your quote.
Looking after it afterwards
After the cure time, these simple habits help:
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
- Do not aim a pressure washer at the joints
- Air rooms to keep condensation down around windows
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so they get particular care.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
What window mastic looks like in Mousehill
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Loseley Park (about 3.8 miles north-east) nearby, there’s older building stock in the area around Mousehill 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.
Managing a site like Milford School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St John the Evangelist's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
