Glazing silicone for homes and businesses in Whitehill
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. If you’re dealing with leaking glazing joints on a rooflight and cracked silicone between glass panels, we can put it right, whatever the surface.
Around Whitehill, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Our work is backed for twelve months.

How we quote for glazing silicone
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The amount of work
- How much old sealant there is and how hard it is to remove
- The product the joint needs
- How easy the joints are to reach
Combining jobs into one visit is generally more efficient than separate visits. You will get one clear quote for the whole job.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Roughly how big the job is
- Photos by email, if that’s easy
- How we’d reach the joints

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Glazing silicone in Whitehill: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For site and facilities teams at buildings such as Woodlea Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St Mark's Sacred Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. For a job in Whitehill, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First, we check where the water gets in.
- The failed silicone is cut out without marking the glass or frame.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

Advice
Landlord and commercial work in Whitehill
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
Surface by surface
Rooflights
Rooflight glazing joints are cut out and renewed. If the leak is from the roof around it, a roofer needs to look.
Glass-to-frame joints
We cut the old silicone from the glass without scratching it and reseal with glazing silicone.
Honest limits
A few problems are outside what sealant work can do:
- Frames that have decayed or split
- A roof that has moved or dropped
- A broken pane or roof panel
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.
What we seal
- Rooflights
- Glass-to-glass joints
- Glass-to-frame joints
- Conservatory frames
- Glass balustrade bases
- Shower screens
What we’re called out for in Whitehill
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. That is why we trace the leak first.
These are the problems we are asked about most:
- Glazing silicone that has cracked or come away
- Shower screens leaking along the wall or tray
- Leaking glazing joints on a rooflight
- Stained, discoloured glazing silicone
Rented homes near Liphook station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
