How we handle glazing silicone in Forest Hill
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it, and if it’s something sealant cannot fix, we will tell you. Typical jobs include water getting into a conservatory at the joints and leaks from the base of a shower screen, on glass-to-glass joints, rooflights and glass-to-frame joints.
Outdoor sealant needs dry, clean surfaces, so work on frames around Forest Hill is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many joints need doing. Somewhere like Forest Hill needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree the joints to be done.
- Old sealant is removed from the glass and frame.
- The surfaces are cleaned with a suitable solvent.
- We apply and tool the new silicone.
- We inspect the work and test it where we can.
How to prepare
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on

Windows and doors in Forest Hill
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Garsington Manor (about 3.6 miles south) are a reminder that the area around Forest Hill has older buildings as well as new. 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.
Schools such as Sandhills Community Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Keep air moving in the conservatory
- Get a new leak looked at quickly
- Look over the glazing joints once a year
- Avoid strong solvents on or near the sealant
Avoid scraping near the new silicone when you clean. A soft cloth or sponge is best.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
Surface by surface
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
What happens if it’s left?
Silicone around glazing needs the right product. General-purpose sealant from a DIY shop may not suit glass or the frame so we choose a glazing silicone instead. Around Forest Hill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
How long will you be here?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer, and we will tell you how long to expect.
Can I add another job to the visit?
Of course. Combining jobs makes good use of the visit.
When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- A frame that needs repairing or replacing
- A broken pane or roof panel
- A sealed unit that has misted inside
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.
Joints and surfaces we work on
- Rooflights
- Shower screens
- Glass-to-frame joints
- Glass-to-glass joints
- Glass balustrade bases
- Conservatory frames
Should I try it myself first?
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 jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
