North Finchley homes and the weather
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Heath Hall (about 2.9 miles south) are a reminder that the area around North Finchley has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to New Southgate station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. For site and facilities teams at buildings such as Sacks Morasha Jewish Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Glazing silicone for homes and businesses in North Finchley
Frameless shower screens rely on sealant to keep water in. The joint down the wall and the one along the tray are common leak points, and we reseal both. We work on conservatory frames, glass balustrade bases and glass-to-glass joints, and common reasons people get in touch are water getting into a conservatory at the joints and stained, discoloured glazing silicone.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Glass-to-glass joints
You see these joints clearly, so a straight, even finish matters.
Conservatory frames
The joints where the conservatory meets the house take a lot of movement. We reseal them with a sealant suited to the frame.

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

A typical job takes a few hours, depending on how many joints need doing. We’ll confirm how long when we quote.
Will there be a smell?
Possibly a little. It fades as the sealant cures.

What affects the quote in North Finchley
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms or windows
- Any working-time requirements on site
- Whether the work is at height
- Any mould that needs treating
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
What we need to know
What to tell us when you ask for a quote:
- Whether it’s a home or a business
- Where the property is
- If someone has resealed it before
- How many joints, rooms or windows are involved
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work and send you a clear quote.
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. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will go through it with you.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It usually takes a few hours, depending on how many joints need doing. For a job in North Finchley, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First, we trace the leak and check it’s coming through a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Clear the area around the work

Advice
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
