Window mastic in Rowsham, done properly
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We’re often asked to deal with cracked sealant at the sill ends and sealant in the wrong colour for the frame, across window sills, uPVC windows and timber windows & doors.
Mastic can only go onto a dry, clean joint, so window work in Rowsham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
We stand behind the work with a 12-month guarantee.

Windows and doors in Rowsham
Historic houses like Ascott House (about 3.8 miles north-east) are a reminder that the area around Rowsham 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 is traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Aylesbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Church of All Saints, the joint between an old wall and a newer frame is usually the first place rain gets in. Managing a site like Wingrave Church of England Combined School? Then the mastic around its windows and doors needs looking after like any other building’s.

How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of frames, longer for a whole house from start to finish. In a small place like Rowsham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each frame is looked over and we agree which ones need resealing.
- 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:

- Any mould that needs treating
- Any working-time requirements on site
- Which sealant suits the joint

- What’s wrong with the joints now
- Access, such as stairs, a lift or height

- The type of property
Every job is quoted individually, so start by telling us what you need. Simply phone 0345 464 0079 or send us an email and describe the job and send photos if you have them.
Why deal with it now?
The work is quick compared with the damage it prevents: it takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Around Rowsham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Surface by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so they get particular care.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Wipe condensation off the frames
- Avoid harsh chemicals near the mastic
- Avoid blasting the frames with a pressure washer
- Check the mastic once a year
Silicone cannot generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
What sealant work cannot fix
Before booking, it’s worth knowing the limits too:
- A frame that has rotted at the joint
- Broken hinges, locks or handles
- Worn gaskets, brush seals or a door that has dropped
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think.
