How we handle window mastic in South Stoke
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include whistling draughts around closed windows and mastic that has split away from the wall, across uPVC windows, timber windows & doors and aluminium frames.
Homes in small places like South Stoke often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Whatever the size of the job, you get the same 12-month guarantee.

Frames and glazing around South Stoke
With historic houses such as Basildon Park (about 3.5 miles south) nearby, there’s older building stock in the area around South Stoke as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Andrew, the joint between an old wall and a newer frame is normally the first place rain gets in. If you let a flat or house near Cholsey station, renewing tired window mastic between tenants heads off draught and damp complaints. Managing a site like South Stoke Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
So the new joints stay in good condition:
- Ventilate rooms so frames do not stay wet inside
- Keep jet washers away from the mastic
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

The process
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as South Stoke, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

Your questions about window mastic in South Stoke
Can you help a landlord with a rental near Cholsey station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
Can I paint over the new sealant?
Silicone generally will not take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We will tell you how long your job needs when we quote.
Why act early in South Stoke
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a small place like South Stoke, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
