Window mastic in Shreding Green
Homes in Shreding Green have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on uPVC windows, timber windows & doors and aluminium frames, and people most often call us about cracked or shrunken mastic around the frame and cracked internal joints between frame and plaster.
Homes in small places like Shreding Green 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.
There’s a 12-month guarantee on every job, large or small.

What window mastic looks like in Shreding Green
With historic houses such as Windsor Castle (about 4 miles south-west) nearby, there’s older building stock in the area around Shreding Green 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as The Iver Village Junior School, its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is usually the first place rain gets in.

What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as that’s a job for a joiner.

When to call us in Shreding Green
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
The most common problems we see are:
- Draughts coming in around windows and doors
- Mastic that’s falling out in pieces
- Rain getting in at the frame or under the sill
- Gaps left after new windows were fitted
Letting a property close to Langley station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

When something else is needed
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Soft or decayed wood in the frame
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you’re not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

Questions from Shreding Green
Is Shreding Green in your area for window mastic?
Yes. We work across London and the South East, and Shreding Green is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Shreding Green?
Yes, Shreding Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How long should I leave it?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Is the work guaranteed?
Yes. Each job is covered for 12 months.
What do you need from me for a quote?
Tell us what needs doing and where, plus photos if you have them. If we need more, we’ll ask.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you work for letting agents?
Yes. As well as homeowners, we work for landlords, agents, businesses and hotels.
Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What affects the cost of window mastic
You will get a clear quote before any work starts. It takes into account:
- Whether there’s mould to deal with
- Whether the work is at height
- Working hours on commercial sites
- The size of the job
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
When you call or email, it’s useful to know:
- The type of property
- The address or postcode of the job
- How we’d reach the joints
- How many joints, rooms or windows are involved
Every job is quoted individually, so the first step is telling us about yours. Simply call 0345 464 0079 or drop us an email and describe the job.
How it works
When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work generally takes a morning for a couple of windows and a door. Somewhere like Shreding Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
