About our glazing silicone in Hartley
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. Typical jobs include conservatory leaks at frame and glazing joints and shower screens leaking along the wall or tray, across glass-to-frame joints, conservatory frames and rooflights.
Many houses in smaller places like Hartley have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Surface by surface
Glass-to-frame joints
The sealant must stick to glass and frame alike. We use a glazing silicone suited to each.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Hartley questions
Do you cover Hartley for glazing silicone?
Yes. Our work covers London and the South East, and Hartley is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear price.
Will you come out to Hartley?
Yes. Hartley is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you replace glass?
No. Misting between panes means the sealed unit has failed and needs replacing by a glazier.
Can landlords and businesses book you?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Is balustrade sealant something you do?
Yes. The sealant joint at the base can be renewed. Fitting glass is a separate trade.
Is the work guaranteed?
Every job comes with our 12-month guarantee, and we’re fully insured.
How much does glazing silicone cost in Hartley?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
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.
Hartley homes and the weather
With historic houses such as Cobham College (about 3.9 miles east) nearby, there’s older building stock in the area around Hartley as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Hartley Primary Academy? Then larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Longfield station, glazing joints are worth checking at the end of a tenancy, before a small leak grows.

Near you in Hartley
Typical jobs here are in homes near Railway Tavern, Rectory Meadow and Longfield Academy, among other places. Hartley’s nearest station is Longfield station, about 0.8 miles north-west. Other landmarks nearby include Darent Valley Hospital (4 miles north-west) and Stone Castle (4.1 miles north). For a walk, there’s Sawyers Lake.
What happens if it’s left?
Resealing cannot fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway, so you can call the right trade. Around Hartley, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

Common problems we fix in Hartley
UV light ages silicone, especially on conservatory roofs. Old silicone hardens, cracks and loses its grip to the glass and frame.
Any of these means the joints need attention:
- Glazing silicone that has cracked or come away
- Water getting into a conservatory at the joints
- Sealant that was laid over old silicone and failed
- Cracked silicone between glass panels
For an older house near a landmark such as Church of Saint Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the cost of glazing silicone
We don’t publish a price list, because no two jobs are the same. What we look at:
- How many areas need sealing
- How much there is to do
- Any mould that needs treating
- When we can work, for business premises
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Asking for a quote
There’s no need for technical detail. Just tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it has been sealed before
- Whether it’s a home or a business
- Where the job is, and your postcode
Every job is quoted individually, so start by telling us what you need. Simply phone 0345 464 0079 or drop us an email and describe the job and send photos if you have them.
What happens on the day
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. It usually takes anything from an hour or two to most of a day, depending on the size of the job. A visit to Hartley is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as 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.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Before we arrive
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- Keep children and pets away from the work area
