Window mastic in Preston Candover, done properly
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on patio & French doors, uPVC windows and aluminium frames, and common reasons people get in touch are cracked sealant at the sill ends and whistling draughts around closed windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Preston Candover is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Wash the frames with mild soapy water
- Repaint timber before it’s bare
- Paint up to the joint, not over it
- Air rooms to keep condensation down around windows
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

What else we do in Preston Candover
DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Windows and doors in Preston Candover
With historic houses such as Hall Place (about 3.6 miles east) nearby, there’s older building stock in the area around Preston Candover as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Preston Candover Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Advice
Signs you need window mastic in Preston Candover
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.
Any of these means the joints need attention:
- Rushed sealant from a window installation
- Mastic that’s falling out in pieces
- Cracked internal joints between frame and plaster
- Cold air getting in at the frame edge
In the older streets around Church of St. Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in.

What the job involves on each surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Why act early in Preston Candover
Resealing frames is a short job: 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. Older cottages and farmhouses around Preston Candover can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.
