Glazing silicone for homes and businesses in Blackhill
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that’s suited to glass and the frame, finished with a neat, even bead. If you are dealing with cracked silicone between glass panels and mouldy sealant around glass panels, we can put it right, whatever the surface.
Around Blackhill, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
There’s a 12-month guarantee on every job, large or small.

Blackhill homes and the weather
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. With historic houses such as Landford Manor (about 2.7 miles north-west) nearby, there’s older building stock in the area around Blackhill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Romsey station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you look after a building such as Wellow School, the mastic around its windows and doors needs looking after like any other building’s. Landford Manor, about 2.7 miles north-west, is one of the historic houses in the wider area around Blackhill, and older homes nearby need a sealant that suits their walls.

Local landmarks in Blackhill

Nearby you’ll also find Tatchbury Mount Hospital (2.9 miles south-east) and King Johns House (3.7 miles north-east). Open spaces near Blackhill include Copythorne Common.
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep air moving in the conservatory
- Wipe the screen down after showering
- Use a gentle glass cleaner and a soft cloth
- Check the silicone on glass every year or so
Avoid scraping near the new silicone when you clean. Stick to a soft cloth.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Why it’s worth doing now in Blackhill
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Older cottages and farmhouses around Blackhill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

What the job involves on each surface
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Glass-to-glass joints
These joints are on show, so a straight, even finish matters.
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
