Harpsden homes and the weather
With historic houses such as Greys Court (about 2.8 miles north-west) nearby, there’s older building stock in the area around Harpsden 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Henley-On-Thames station, glazing joints are worth checking at the end of a tenancy, before a small leak grows. For an older house near a landmark such as Church of St Margaret, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Glazing silicone in Harpsden
Across Harpsden, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. We work on glass balustrade bases, glass-to-frame joints and conservatory frames, and the jobs we see most are water running down inside the glass and glazing silicone that has cracked or come away.
Somewhere as small as Harpsden, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Do not leave a drip for the next storm
- Run a squeegee over the glass when you are done
- Keep conservatory gutters clear of leaves
- Clean glass with a mild cleaner and a soft cloth
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
A small conservatory leak soon spreads. Water travels along the frame and into the wall so it’s best dealt with straight away.
Why act early in Harpsden
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before it shows. In a small place like Harpsden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Common problems we fix in Harpsden
Heat and cold make glass and frames move at different rates. In time, the sealant splits or pulls away.
People normally contact us after spotting something like this:
- Black or yellowed silicone on glass joints
- Glass-to-glass joints that have split
- Water running down inside the glass
- Silicone pulling away from the glass
For site and facilities teams at buildings such as Trinity Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking

- Which sealant they’ll use, and why
Different surfaces, different methods
Glass-to-glass joints
Silicone joins glass panels in many frameless designs. We renew it with a clear or matching glazing silicone.
Shower screens
Silicone holds the water in on frameless screens. We renew it without marking the glass.
