Surface by surface
Rooflights
Water around a rooflight isn’t always the sealant. We find the cause first.
Conservatory frames
Frame-to-wall joints on a conservatory move with the weather. We reseal them with a sealant suited to the frame.
About our glazing silicone in Adeyfield
Across Adeyfield, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. If you have water getting into a conservatory at the joints and mouldy sealant around glass panels, we can put it right, whatever the surface.
Homes around Adeyfield range from older properties to newer houses, and their windows range just as widely. The right sealant depends on the frame and on what it sits in.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

What we cannot put right
Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:
- Structural problems with a conservatory roof
- Rotten or badly damaged frames
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we will tell you honestly.
Surfaces we seal
- Glass-to-frame joints
- Shower screens
- Conservatory frames
- Glass-to-glass joints
- Rooflights
- Glass balustrade bases
Can I do it myself?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What affects the cost of glazing silicone
Some jobs are bigger than they look, and some smaller. The main factors:
- The product the joint needs
- Whether old sealant or filler has to be cut out
- The number and length of the joints
- The number of rooms or windows
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Roughly how big the job is
- If someone has resealed it before
- What’s wrong with the joints now
- Where the job is, and your postcode
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes anything from an hour or two to most of a day, depending on the size of the job. For a job in Adeyfield, we agree the time, the access and parking before the day. 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.
- The joint is cleaned and degreased.
- We lay the new bead and tool it smooth.
- Each joint is checked and, where possible, water-tested.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
Getting a quote
Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details.
Related advice
Adeyfield questions
Do older homes in Adeyfield need their sealant replacing?
Often, yes: cracked, shrunken or mouldy sealant has done its job. The key is cutting all the old sealant out, as new sealant will not bond to it.
Is Adeyfield within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you just put new silicone over the old?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
How do I get a quote for glazing silicone in Adeyfield?
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.
Is the work guaranteed?
All our work has a one-year guarantee, and we’re fully insured.
Do you replace glass?
That’s not something we do. A misted unit has failed inside, and a glazier needs to replace it.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
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.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Do not leave a drip for the next storm
- Stick to mild cleaners on glass
- Keep scrapers and blades away from the silicone
- Check the gutters above the glazing for debris
On shower screens, wipe or squeegee after use and let the room air. That slows mould growth on the bead.
A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.

Other services in Adeyfield
Windows and doors in Adeyfield
Adeyfield is part of Hemel Hempstead, one of the post-war new towns. Many homes date from the post-war decades, and many will have had their original windows replaced. That mastic ages as well, and sills and frame heads are where leaks start. 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.
For site and facilities teams at buildings such as Hobletts Manor Infants' School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to St Barnabas include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Apsley station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
