How we handle glazing silicone in Green Street
We work across Green Street on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method. We work on glass balustrade bases, glass-to-frame joints and glass-to-glass joints, and the jobs we see most are sealant that was laid over old silicone and failed and failed sealant around rooflight glass.
Somewhere as small as Green Street, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

What affects the cost of glazing silicone
There’s no set price list. What we look at:
- Any working-time requirements on site
- How easy the joints are to reach
- The old material and how stubborn it is
- The number and length of the joints
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Roughly how big the job is
- Whether it’s a home or a business
- Any access issues, like height or stairs
- If someone has resealed it before
Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we will come back to you with a quote.
What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job usually takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Green Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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 fails, we can still redo it.
Honest limits
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- Failed flashing around a conservatory
- A frame that needs repairing or replacing
- A sealed unit that has misted inside
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal
- Glass-to-frame joints
- Glass-to-glass joints
- Rooflights
- Conservatory frames
- Shower screens
- Glass balustrade bases

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Check the silicone on glass every year or so
- Ventilate the conservatory to cut condensation
- Clear the conservatory gutters regularly
- Avoid scraping close to the bead
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Shower screen leaks can go unnoticed. Water can soak into the floor or reach the room below before you spot it.

Glazing silicone in Green Street: local notes
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 Wyllyotts Manor (about 3.7 miles north-east) nearby, there’s older building stock in the area around Green Street as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Elstree & Borehamwood station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you look after a building such as Parkside Community Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near St Michael and All Angels Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Green Street is about 1 mile north of Borehamwood, in Hertfordshire.

How the job changes by surface
Glass balustrade bases
We reseal the joint where the glass meets the base channel. Glass fitting is a separate trade.
Glass-to-frame joints
Silicone at the glass edge seals it into the frame. When it splits, water can get into the frame.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
