Glazing silicone in Westwick Row, done properly
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. When it cracks or lets go, water gets in. We cut it out and reseal with a glazing silicone suited to the joint. If you have drips on the inside of a conservatory window and sealant that was laid over old silicone and failed, we can put it right, on shower screens, conservatory frames and glass-to-glass joints alike.
Homes in small places like Westwick Row 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.
We stand behind the work with a one-year guarantee.

What glazing silicone looks like in Westwick Row
With historic houses such as Batchwood Hall (about 3.1 miles north-east) nearby, there’s older building stock in the area around Westwick Row as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Hemel Hempstead, which Westwick Row is part of, is one of England’s post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. That mastic ages as well, and sills and frame heads are where leaks start.
If you look after a building such as Leverstock Green Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Church of Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Apsley station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Why it’s worth doing now in Westwick Row
You don’t need new glazing because the sealant has gone. Sound glass and frames usually just need resealing. Where a wall is exposed, as many are in small places like Westwick Row, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

DIY versus a professional finish
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Keeping the joints in good condition
Looking after new joints is easy:
- Keep air moving in the conservatory
- Keep scrapers and blades away from the silicone
- Do not leave a drip for the next storm
- Check the gutters above the glazing for debris
Use mild cleaners on and around the silicone. Harsh solvents may damage the bead.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
