Glazing silicone for homes and businesses in Brondesbury Park
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. If you have water running down inside the glass and rooflight joints letting water in, we can put it right, on conservatory frames, glass-to-frame joints and glass balustrade bases alike.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Brondesbury Park.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Glazing silicone in Brondesbury Park: local notes
Historic houses like Northolt Manor (about 2.9 miles west) are a reminder that the area around Brondesbury Park 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Wembley Central 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 Park Lane Primary School, the mastic around its windows and doors needs looking after like any other building’s. As a London address, Brondesbury Park can be tricky for parking: let us know about parking bays, permits or a driveway.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Keep harsh solvents off the silicone
- Look over the glazing joints once a year
- Check the gutters above the glazing for debris
- Keep scrapers and blades away from the silicone
Avoid scraping near the new silicone when you clean. Stick to a soft cloth.
Do not leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for most jobs. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Brondesbury Park. A visitor permit or a nearby bay makes the visit run more smoothly.
- We look at the glazing and agree which joints need resealing.
- 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.
Preparing for the visit

Advice
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again.
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.

Do you offer different sealant colours?
Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before work begins.
Do you fit new glass or sealed units?
We don’t replace glass. We look after the sealant joints, and we’ll tell you if a unit looks like it has failed.
What sealant do you use on glazing?
Glass needs a sealant made for glazing. We use neutral-cure glazing silicone and anti-fungal silicone in wet areas.
Can a conservatory leak be sealed?
That depends where the water is getting in. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
What affects the cost of glazing silicone
The price is agreed before any work begins. It takes into account:
- Mould in or behind the old joints
- The number and length of the joints
- When we can work, for business premises
- The product the joint needs
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we’ll talk you through it.
