Window mastic in Fairford Leys
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. Common call-outs are for draughty joints inside around the window and cold air getting in at the frame edge, on uPVC windows, patio & French doors and window sills.
In smaller places like Fairford Leys, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. The right sealant depends on the frame and on what it sits in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Signs you need window mastic in Fairford Leys
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Look out for any of the following:
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Black, perished sealant on frames
- Cracked sealant at the sill ends
Managing a site like St Mary's Church of England School? Then the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- How long to leave it before use
- Whether the sealant suits the joint
- Whether you can choose the colour
- Is the old sealant removed completely?
What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Why act early in Fairford Leys
Choosing the product is half the job. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In a smaller place like Fairford Leys, 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.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Frames and glazing around Fairford Leys
With historic houses such as Waddesdon Manor (about 4.6 miles north-west) nearby, there’s older building stock in the area around Fairford Leys 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. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Aylesbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Fairford Leys Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep paint and stain on wooden frames in good order
- Do not paint over the silicone
- Use gentle cleaners on frames and sealant
- Avoid harsh chemicals near the mastic
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a few frames, or a day or more for a whole house, depending on how much there is to do. A visit to Fairford Leys is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Let us know about parking restrictions
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
