Glazing & conservatory sealant in Shelley, Essex
Our applicators work in Shelley on glazing silicone for conservatories, rooflights, glass panels and shower screens. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Failed joints on frameless glass
- Leaks from the base of a shower screen
- Water getting into a conservatory at the joints
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Run a squeegee over the glass when you’re done
- Ventilate the conservatory to cut condensation
- Use a gentle glass cleaner and a soft cloth
- Avoid scraping close to the bead
Gentle products are best near the sealant. Harsh solvents may damage the bead.
A leaking shower screen may not show at first. It can damage the floor or the ceiling below before you spot it.
Glazing silicone in Shelley
Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. We work on glass balustrade bases, conservatory frames and shower screens, and common reasons people get in touch are water running down inside the glass and sealant that was laid over old silicone and failed.
In a village or hamlet like Shelley, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, you get the same 12-month guarantee.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. It normally takes anything from an hour or two to most of a day, depending on the size of the job. Somewhere as small as Shelley, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- 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 about any previous sealing or DIY attempts
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Advice
FAQs for Shelley
Do you cover smaller places like Shelley?
Yes. Shelley is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What guarantee comes with glazing silicone in Shelley?
All our work, in Shelley and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
I’m a tenant. Can you help?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Which products 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.
Do you replace glass?
Glass replacement isn’t our trade. We look after the sealant joints, and we’ll tell you if a unit looks like it has failed.
Can you just put new silicone over the old?
It doesn’t last. The new bead can’t grip the old one so we take it all out and start clean.
How long will you be here?
That depends on the amount of work, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We’ll give you a better idea when we quote.

Glazing silicone in Shelley: local notes
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. With historic houses such as Hill Hall (about 4.8 miles south-west) nearby, there’s older building stock in the area around Shelley as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What affects the quote in Shelley
Every job gets its own quote. This is what makes a difference:
- How easy the joints are to reach
- When we can work, for business premises
- The size of the job
- Any mould that needs treating
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- A few pictures by email, if you can
- Where the property is
- Roughly how big the job is
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
What we’re called out for in Shelley
Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass, and acetoxy types can attack some frame materials.
Any of these means the joints need attention:
- Water tracking down the inner face of the glass
- Glass-to-glass joints that have split
- Glazing silicone that has cracked or come away
- New silicone smeared over old sealant
Schools such as Ongar Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- Whether VAT is included
- What preparation is included
- What product goes in the joint
- What happens if they find a problem under the old sealant
How the job changes by surface
Glass balustrade bases
Glass balustrades sit in a channel that’s often finished with sealant. Failed sealant there lets water collect.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.
