About our window mastic in Egham Hythe
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Common call-outs are for draughty joints inside around the window and cold air getting in at the frame edge, on window sills, composite doors and uPVC windows.
Around Egham Hythe, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Why act early in Egham Hythe
Working on frames from a ladder with a sealant gun is not easy, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. In a smaller place like Egham Hythe, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

- Approved under the ARBOMaster scheme

Where are you based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Does the work come with a guarantee?
Yes. Each job is covered for 12 months.
Can you reach windows above the ground floor?
Usually, yes. We plan safe access before the job.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Is it OK to seal over old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clean frames with a soft cloth and soapy water
- Walk round the house once a year and look at the joints
- Avoid harsh chemicals near the mastic
- Repaint timber before it’s bare
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
The process
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. A visit to Egham Hythe is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Mention any parking rules near the property
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

Signs you need window mastic in Egham Hythe
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Any of these means the joints need attention:
- Damp patches on the reveal after heavy rain
- Whistling draughts around closed windows
- Draughty joints inside around the window
- A bead that doesn’t match the frame
Rented homes near Egham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- How long the guarantee is
- How the colour is chosen
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
Different surfaces, different methods
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the new bead is laid against the frame and the wall and tooled smooth.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.

Windows and doors in Egham Hythe
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Botleys Mansion (about 3.5 miles south) nearby, there’s older building stock in the area around Egham Hythe 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.
Schools such as Thorpe Lea Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Paul's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
