Window mastic in Silchester
Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, ring 0345 464 0079 or drop us an email with the number of frames and any access details. We work on patio & French doors, aluminium frames and window sills, and common reasons people get in touch are gaps left after new windows were fitted and draughts coming in around windows and doors.
Somewhere as small as Silchester, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in Silchester and everywhere else we cover.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Air rooms to keep condensation down around windows
- Keep drainage slots and sill grooves clear
- Don’t paint over the silicone
- Do not use solvent cleaners on the joint
Try not to touch the new joint while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Silchester homes and the weather
Historic houses like The Vyne (about 3.3 miles south) are a reminder that the area around Silchester 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’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.
For site and facilities teams at buildings such as Silchester Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Bramley (Hants) station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Do you need window mastic in Silchester?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Signs it’s time to call us include:
- Draughty joints inside around the window
- Leaking joints at the ends of sills
- Black, perished sealant on frames
- A bead that doesn’t match the frame
In the older streets around Saint Luke's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the quote in Silchester
There’s no set price list, because no two jobs are the same. What we look at:
- The amount of work
- The type of sealant required
- Access and height
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
To help us quote quickly, let us know:
- The rough size of the job
- A few photos by email, if you can
- The problem you’ve noticed
- If someone has resealed it before
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or send us an email with the details, and pictures are welcome.
Why deal with it now?
The work is quick compared with the damage it prevents: it takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Silchester, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

What we can’t put right
In fairness, some problems need a different trade:
- Damp problems in the wall away from the window
- Draughts through the window seals rather than the frame
- Condensation trapped between the panes
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

What happens on the day
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Silchester, the journey is planned in advance: 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.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- Mention any tricky access
