Silicone joins glass panels in many frameless designs. We reseal with a suitable glazing silicone.
Glazing silicone in North Lee, done properly
Across North Lee, 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-to-frame joints, rooflights and glass balustrade bases, and common reasons people get in touch are leaks from the base of a shower screen and glass-to-glass joints that have split.
Homes in small places like North Lee 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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

How much does glazing silicone cost in North Lee?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or drop us an email.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours, depending on how many joints need doing, and the area is left clean. Somewhere like North Lee needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the glazing and agree which joints need resealing.
- Old sealant is removed from the glass and frame.
- We clean and prepare the joint.
- New glazing silicone goes in and is finished neatly.
- The joints are checked before we leave.
Preparing for the visit
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Use gentle products around the joints
- Ventilate the conservatory to cut condensation
- Clear the conservatory gutters regularly
- Don’t use a blade near the sealant
Avoid scraping near the new silicone when you clean. Stick to a soft cloth.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall so it’s best dealt with straight away.

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.
Schools such as Stoke Mandeville Combined School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Stoke Mandeville station change hands often, and leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies. In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why act early in North Lee
Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. Around North Lee, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
