Crockenhill homes and the weather
With historic houses such as Lullingstone Castle (about 2.3 miles south-east) nearby, there’s older building stock in the area around Crockenhill as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of All Souls, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Swanley station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Why act early in Crockenhill
A leaking joint won’t fix itself. Left, water can mark floors, damage plaster and rot timber so early action saves a bigger repair. In a small place like Crockenhill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Work for landlords, hotels and businesses

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so here’s what sealant cannot put right:
- A sagging or failing conservatory roof

Quotes for glazing silicone in Crockenhill
You’ll get a clear quote before any work starts. It’s based on:
- Whether there’s mould to deal with
- How many areas need sealing
- How easy the joints are to reach
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Asking for a quote
To make quoting easier, please include:
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- Where the property is
- Pictures of the joints, sent by email
There’s no standard price list. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or drop us an email.

What else we do in Crockenhill
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours, depending on how many joints need doing from start to finish. Somewhere like Crockenhill needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
- Each joint is checked and, where possible, water-tested.
How to prepare
- Mention if the joints have been sealed before
- Clear items away from the joints we are working on
- Let us know about parking restrictions

Common problems we fix in Crockenhill
Sealant laid over old sealant doesn’t last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
Keep an eye out for these signs:
- Glass-to-glass joints that have split
- Water tracking down the inner face of the glass
- Black or yellowed silicone on glass joints
- Leaking glazing joints on a rooflight
If you look after a building such as Crockenhill Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Your questions about glazing silicone in Crockenhill
Is Crockenhill within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do glazing silicone in Crockenhill?
Yes, Crockenhill is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you just put new silicone over the old?
New silicone will not bond to old silicone, so a top-up soon lets water through. We cut out the old sealant first.
Will you leave 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.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Can you fix a leaking conservatory?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we will tell you.
Can you reseal a frameless shower screen?
We can. We remove the old silicone carefully before cleaning and resealing.
Is balustrade sealant something you do?
Yes. We cut out the failed sealant and reseal the base joint with a suitable product.
