Glazing Silicone in Crow Green
Our applicators work in Crow Green on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Mouldy sealant around glass panels
- Water getting into a conservatory at the joints
- Failed sealant around rooflight glass
Common problems we fix in Crow Green
Sealant laid over old sealant doesn’t last. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
Look out for any of the following:
- Sealant that was laid over old silicone and failed
- Leaking glazing joints on a rooflight
- Water tracking down the inner face of the glass
- Conservatory leaks at frame and glazing joints
Letting a property close to Shenfield station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

How we handle glazing silicone in Crow Green
Sealant on glazing does not last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Renewing it keeps glazing joints doing their job. Typical jobs include rooflight joints letting water in and glazing silicone that has cracked or come away, across conservatory frames, shower screens and rooflights.
Mastic can only go onto a dry, clean joint, so window work in Crow Green is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work is covered by our 12-month guarantee, wherever you are in Essex.

Crow Green questions
Do you cover Crow Green for glazing silicone?
Yes. Our work covers London and the South East, and Crow Green is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
Is Crow Green within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it possible to redo the silicone on a shower screen?
Yes, we do these often. The screen is resealed with anti-fungal silicone suited to bathrooms.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Are you insured?
Yes. We are fully insured.
Where is Mr Mastic based?
We work from Crawley. We cover Crow Green and the rest of Essex, along with the rest of our area.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.

How it works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on how many joints need doing. Somewhere like Crow Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by finding the leak and making sure sealant is the cause.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions
- Tell us about any water getting in

Related advice
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Stick to mild cleaners on glass
- Open vents or windows to let moisture out
- Keep scrapers and blades away from the silicone
- Check the silicone on glass every year or so
Follow the cure time we give you before the joints get wet. After that, clean glass with a mild cleaner.
If silicone on glass has cracked, water is already getting in. Resealing now is a small job, compared with repairing damaged frames or plaster.
DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Different surfaces, different methods
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
What we can’t put right
We’d rather tell you now than do work that will not last, so these are the limits:
- A roof that has moved or dropped
- Cracked or broken glass
- Frames that have decayed or split
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

Frames and glazing around Crow Green
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Ingatestone Hall (about 4.4 miles east) nearby, there’s older building stock in the area around Crow Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Larchwood Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Trinity Church, the joint between an old wall and a newer frame is generally the first place rain gets in.
