Why deal with it now?
A new conservatory roof is a big job. If the leak is a failed sealant joint, resealing is far simpler. If the roof is the problem, we will say so. Where a wall is exposed, as many are in small places like Rettendon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

About our glazing silicone in Rettendon
We renew glazing silicone on conservatories, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. We work on rooflights, shower screens and glass-to-glass joints, and the jobs we see most are water escaping where a screen meets the wall and sealant that was laid over old silicone and failed.
Mastic can only go onto a dry, clean joint, so window work in Rettendon is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Squeegee the shower screen after each use
- Don’t use a blade near the sealant
- Inspect the sealant on glazing annually
- Clean glass with a mild cleaner and a soft cloth
Gentle products are best near the sealant. Strong solvents can soften or mark it.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the leak gets worse.
What happens on the day
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes a few hours for most jobs in most cases. For a village or hamlet like Rettendon, the journey is planned in advance: 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.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- 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
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Rettendon homes and the weather
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Danbury Place (about 4.2 miles north) nearby, there’s older building stock in the area around Rettendon as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Battlesbridge station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Common questions in Rettendon
Do you cover smaller places like Rettendon?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Battlesbridge station?
Yes. We work for landlords and agents as well as homeowners. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you replace glass?
No. We renew the sealant. Glass and sealed units need a glazier.
Can you just put new silicone over the old?
It does not last. The new bead can’t grip the old one, so we remove the old sealant and clean the joint.
Can you reseal the base of a glass balustrade?
We can, if the base joint is sealed. Send us photos and we will take a look.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used before we leave.
Is the work guaranteed?
Every job comes with our one-year guarantee, and we are fully insured.
