Window Mastic in Wraysbury
Our applicators work in Wraysbury on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Old mastic that has gone black or come away
- Damp patches on the reveal after heavy rain
- Gaps where the sill meets the wall
How it works
On the day, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work generally takes most of a day for a typical house, less for a few frames. For a job in Wraysbury, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Preparing for the visit
- Let us know about parking restrictions
- Move anything stored near the joints
- Keep pets and children clear of the area while we work

Advice
Window mastic in Wraysbury
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on uPVC windows, composite doors and window sills, and people most often call us about white mastic on grey or black frames and old mastic that has gone black or come away.
Around Wraysbury, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Window mastic in Wraysbury: local notes
With historic houses such as Frogmore House (about 1.8 miles north-west) nearby, there’s older building stock in the area around Wraysbury as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Andrew, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you look after a building such as Wraysbury Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
- Don’t aim a pressure washer at the joints
- Keep solvents and bleach off the sealant
Try not to touch the new joint while it cures, for as long as we advise. Do not point a pressure washer at the joints.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.
How we quote for window mastic
We do not publish a price list. The quote depends on:
- The number of rooms or windows
- How easy the joints are to reach
- The product the joint needs
- Working hours on commercial sites
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- The type of property
- How we’d reach the joints

Your questions about window mastic in Wraysbury
Do you work for landlords with property near Sunnymeads station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is Wraysbury within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Do you have insurance?
Yes. We are fully insured.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Does the work come with a guarantee?
Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.
When to call us in Wraysbury
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
Any of these means the joints need attention:
- Cracked or shrunken mastic around the frame
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- Cracked sealant at the sill ends
If you let a flat or house near Sunnymeads station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
