Frames and glazing around North Heath
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. With historic houses such as Old Place Manor (about 2.1 miles south-west) nearby, there’s older building stock in the area around North Heath 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’s traditional sand mastic.
For landlords with property near Pulborough station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

About our glazing silicone in North Heath
Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone that’s suited to glass and the frame, and we tool it to a neat, even finish. If you’re dealing with leaks where conservatory glass meets the frame and mouldy sealant around glass panels, we can put it right, on conservatory frames, rooflights and glass balustrade bases alike.
Homes in small places like North Heath often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months.

Surface by surface
Shower screens
Frameless screens rely on silicone at the base and wall. We renew it without marking the glass.
Glass balustrade bases
The base joint is cut out and resealed. Glass fitting is a separate trade.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Ventilate the conservatory to cut condensation
- Run a squeegee over the glass when you’re done
- Keep harsh solvents off the silicone
- Inspect the sealant on glazing annually
Keep conservatory gutters clear, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we will find out which.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens if it’s left?
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before it shows. Where a wall is exposed, as many are in small places like North Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.

How we quote for glazing silicone
The quote reflects the job in front of us. We take into account:
- How many rooms, windows or areas are involved
- Whether the work is at height
- The size of the job
- The type of sealant required
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.
What to tell us for a quote
To make quoting easier, let us know:
- The problem you’ve noticed
- How we’d reach the joints
- If someone has resealed it before
- The rough size of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
