Window mastic for homes and businesses in Shepperton Green
Homes in Shepperton Green have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. Typical jobs include untidy mastic left by window fitters and leaking joints at the ends of sills, on timber windows & doors, uPVC windows and aluminium frames.
Homes around Shepperton Green range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Our work is backed for twelve months.

Looking after it afterwards
Aftercare is simple:
- Keep timber frames painted
- Clear any debris from frame drain holes
- Wipe condensation off the frames
- Don’t use solvent cleaners on the joint
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
How the visit works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job generally takes most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. Parking around Shepperton Green is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Preparing for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Let us know about stairs, lifts or work at height

Advice
Honest limits
Before booking, it’s worth knowing the limits too:

- A frame that has rotted at the joint
- A failed sealed unit that has misted up
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured for the work.
Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, 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.
How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.

Why it’s worth doing now in Shepperton Green
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In an older home around Shepperton Green, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

Common questions in Shepperton Green
Will you come out to Shepperton Green?
Yes. Shepperton Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is Shepperton Green in your area for window mastic?
Yes. Our work covers London and the South East, and Shepperton Green is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Do you have sealant for grey or black windows?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
Is it OK to seal over old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
How long before the joint can be used?
It depends on the product and the conditions. We tell you how long to leave it before we go.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
Windows and doors in Shepperton Green
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Botleys Mansion (about 3.6 miles south-west) are a reminder that the area around Shepperton Green has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Shepperton station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Church of St Mary Magdalene include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Saxon Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
