Why act early in Great Waltham
Topping up old silicone can look like a fix, but new silicone won’t bond to old and water soon finds its way back. Cutting out and resealing properly lasts. Around Great Waltham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

How we handle glazing silicone in Great Waltham
Frameless shower screens rely on sealant to keep water in. Leaks normally come from the wall joint or the tray joint, and we reseal both. If you have leaks where conservatory glass meets the frame and stained, discoloured glazing silicone, we can help.
Homes in small places like Great Waltham often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, large or small.

The process
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours, depending on how many joints need doing, including the tidy-up. For a village or hamlet like Great Waltham, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- 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.
How to prepare
- Mention any leaks or damp you’ve noticed
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

Advice
What affects the cost of glazing silicone
Every job gets its own quote. These are the things that affect it:
- Whether the work is at height
- Which sealant suits the joint
- Mould in or behind the old joints
- The old material and how stubborn it is
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Access, such as stairs, a lift or height
- A few pictures by email, if you can
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved.
Windows and doors in Great Waltham
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.
For site and facilities teams at buildings such as Chelmer Valley High School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of SS Mary and Laurence, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Beaulieu Park station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Aftercare tips
After the cure time, these simple habits help:
- Clear the conservatory gutters regularly
- Open vents or windows to let moisture out
- Stick to mild cleaners on glass
- Avoid scraping close to the bead
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we will find out which.
DIY sealant or a professional job?
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’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
What we can’t put right
A few problems are outside what sealant work can do:
- Structural problems with a conservatory roof
- Glass that needs replacing
- Frames that have decayed or split
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.
