Window mastic for homes and businesses in Walton Court
Around Walton Court we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on composite doors, aluminium frames and uPVC windows, and common reasons people get in touch are draughts coming in around windows and doors and rain getting in at the frame or under the sill.
Many houses in smaller places like Walton Court have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.
Every job comes with a 12-month guarantee.

Surface by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
What we’re called out for in Walton Court
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That’s what backing rod is for.
It’s worth asking for a quote if you see:
- Old mastic that has gone black or come away
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
- Cracked internal joints between frame and plaster
Managing a site like Ashmead Combined School? Then its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- What insurance they hold
- When the joint can take water or movement
- Whether the sealant suits the joint
- What preparation is included
What affects the cost of window mastic
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- Any mould that needs treating
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
The cost depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Where the property is
- Whether it has been sealed before
- The problem you’ve noticed
- Any access issues, like height or stairs
Every job is quoted individually, so start by telling us what you need. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from an hour or two to a full day, depending on how many frames there are. In a smaller place like Walton Court, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Can I do it myself?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Window mastic in Walton Court: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In the older streets around Church of the Good Shepherd, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Aylesbury station, renewing tired window mastic between tenants heads off draught and damp complaints.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep jet washers away from the mastic
- Avoid harsh chemicals near the mastic
- Walk round the house once a year and look at the joints
- Repaint timber before it’s bare
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
