Window mastic in Woodmansterne
Around Woodmansterne we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Typical jobs include cracked internal joints between frame and plaster and whistling draughts around closed windows, across window sills, uPVC windows and patio & French doors.
Many houses in smaller places like Woodmansterne have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Our work is backed for twelve months.

For landlords and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
How the job changes by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Window mastic in Woodmansterne: local notes
Historic houses like Nonsuch Mansion (about 3.9 miles north-west) are a reminder that the area around Woodmansterne has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Chipstead station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Chipstead Valley Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- Mould in or behind the old joints
- How easy the joints are to reach
- The number of rooms or windows
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.

Do you need window mastic in Woodmansterne?
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Signs it’s time to call us include:
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
- Mastic that has split away from the wall
- Damp patches on the reveal after heavy rain
In the older streets around St Peter's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
What your quote should include
- Whether VAT is included
- How the colour is chosen
- What product goes in the joint
- How the joint is cleaned and prepared
Looking after it afterwards
Looking after new joints is easy:
- Make sure the drainage slots aren’t blocked
- Don’t aim a pressure washer at the joints
- Walk round the house once a year and look at the joints
- Keep paint off silicone joints
Most silicone sealants will not take paint, so mention any painting plans before any work starts. There are paintable sealants for joints that need it.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. A visit to Woodmansterne is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Keep children and pets away from the work area
- Mention any parking rules near the property
- Mention any tricky access

Advice
What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we will tell you. Around Woodmansterne, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
