Window mastic in Wisley, done properly
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before we start. To get one, phone 0345 464 0079 or email us with the number of frames and any access details for window mastic in Wisley. If you have cracked or shrunken mastic around the frame and gaps left after new windows were fitted, we can help.
Homes in small places like Wisley 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

FAQs for Wisley
I let a flat near West Byfleet station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear quote.
Will you come out to Wisley?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you quote for more than one area?
Yes, we can. Several rooms, windows or areas can go on one quote.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How long does it take to reseal the windows on a house?
The work takes most of a day for a typical house, less for a few frames. Access and how stubborn the old mastic is affect the time most.
Different surfaces, different methods
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
Honest limits
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Broken hinges, locks or handles
- Draughts through the window seals rather than the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
What we seal
- uPVC windows
- Patio & French doors
- Composite doors
- Timber windows & doors
- Window sills
- Aluminium frames
Window mastic in Wisley: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Byfleet Manor (about 0.8 miles north-east) nearby, there’s older building stock in the area around Wisley 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.
If you live in an older home near Wisley Church, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near West Byfleet station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Do you need window mastic in Wisley?
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between the frame and the inside reveal
- Black, perished sealant on frames
- Rushed sealant from a window installation
- Water coming in at the bottom corners of a door
If you look after a building such as St Mary's CofE Controlled Primary School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- Whether you can choose the colour
- What guarantee comes with the work
- When the joint can take water or movement
- Who does the work, and how experienced they are

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a morning for a couple of windows and a door and we leave things clean and tidy. In a small place like Wisley, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Aftercare tips
After the cure time, these simple habits help:
- Walk round the house once a year and look at the joints
- Use gentle cleaners on frames and sealant
- Keep paint and stain on wooden frames in good order
- Make sure the drainage slots aren’t blocked
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
DIY sealant or a professional job?
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, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
