Looking after it afterwards
A little care helps the new joints last. Our advice:
- Do not leave a drip for the next storm
- Wipe the screen down after showering
- Clean glass with a mild cleaner and a soft cloth
- Avoid scraping close to the bead
Avoid scraping near the new silicone when you clean. Stick to a soft cloth.
Shower screen leaks can go unnoticed. It can damage the floor or the ceiling below long before you see it.
About our glazing silicone in Purley on Thames
Conservatory leaks often start at a sealant joint, where glass meets frame or frame meets wall. We trace the leak to the joint and reseal it and tell you plainly if the cause is something else. If you’re dealing with black or yellowed silicone on glass joints and drips on the inside of a conservatory window, we can help.
Houses in smaller places like Purley on Thames can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.

Purley on Thames homes and the weather
Historic houses like Mapledurham House (about 0.6 miles north-east) are a reminder that the area around Purley on Thames has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Tilehurst station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. Managing a site like Purley CofE Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed 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 does not work out, we can still put it right.
The process
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for most jobs. In a smaller place like Purley on Thames, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We trace the leak and confirm it’s a sealant joint.
- 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
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we’re working on

We quote each job individually. These are the things that affect it:
- Whether the work is at height
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
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 make a difference, and we will explain the quote if you ask.

- If someone has resealed it before
- How many joints, rooms or windows are involved

Glass balustrades sit in a channel that’s often finished with sealant. Failed sealant there lets water collect.
