Why deal with it now?
A new conservatory roof is a big job. Where the water is getting in through sealant, resealing is far simpler. If it’s the roof itself, we will tell you. Older cottages and farmhouses around New Denham can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

What glazing silicone looks like in New Denham
With historic houses such as Ickenham Hall (about 2.1 miles east) nearby, there’s older building stock in the area around New Denham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, 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 Hermitage Primary School, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Denham station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Common problems we fix in New Denham
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
If you can see any of these, it’s time to have the joints looked at:
- Failed sealant around rooflight glass
- Water tracking down the inner face of the glass
- New silicone smeared over old sealant
- Glass-to-glass joints that have split
In the older streets around St Francis, the joint between an old wall and a newer frame is generally the first place rain gets in.

Surface by surface
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.
Conservatory frames
Leaks often start where the frame meets the wall. We cut out the old sealant and reseal.
Aftercare tips
Good habits help new joints last longer. A few tips:
- Wipe the screen down after showering
- Don’t use a blade near the sealant
- Use gentle products around the joints
- Stick to mild cleaners on glass
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
