Leave it or put it right?
If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly and point you to a glazier or roofer. Where a wall is exposed, as many are in small places like Dedham Heath, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

Glazing silicone in Dedham Heath, done properly
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it, and if it’s something sealant cannot fix, we’ll tell you. Common call-outs are for leaking glazing joints on a rooflight and failed joints on frameless glass, across glass balustrade bases, glass-to-glass joints and rooflights.
Mastic can only go onto a dry, clean joint, so window work in Dedham Heath is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job is covered by a one-year guarantee, wherever you are in Essex.

What we do, step by step
We keep the work tidy and contained to the area we’re working on. The job generally takes a few hours for most jobs, and we explain the cure time before we leave.

Everything for the job comes with us, so a second trip is avoided where possible.

What affects the cost of glazing silicone
There’s no set price list, because jobs vary so much. What we look at:
- Working hours on commercial sites
- The product the joint needs
- How easy the joints are to reach
- Whether there’s mould to deal with
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- Where the property is
- Whether it has been sealed before
- Pictures of the joints, sent by email
- How many joints, rooms or windows are involved
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or email us.
What we can’t put right
It helps to know what we cannot do too:
- Leaks from the roof covering or flashing (a roofer’s job)
- Rotten or badly damaged frames
- A sagging or failing conservatory roof
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Surfaces we seal
- Glass-to-glass joints
- Glass balustrade bases
- Rooflights
- Conservatory frames
- Glass-to-frame joints
- Shower screens
Do you need glazing silicone in Dedham Heath?
Not every leak is a sealant problem: failed roof panels, slipped glazing bars and blocked gutters cause them too. We find the cause before we seal anything.
If you can see any of these, it’s time to have the joints looked at:
- Water running down inside the glass
- Failed sealant around rooflight glass
- Water getting into a conservatory at the joints
- Water escaping where a screen meets the wall
Letting a property close to Manningtree station? Then leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
Before you book anyone
- Are they insured?
- How the joint is cleaned and prepared
- What the cure time is
- Which colour the sealant will be
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. 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.
Dedham Heath: your questions answered
Do you work for landlords with property near Manningtree station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Is Dedham Heath within the area you cover?
Yes. Dedham Heath 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.
Can you do several jobs on one visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient, so mention them when you ask for a quote.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Can you fix a leaking conservatory?
It depends on the cause. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that normally means someone at home.
Do you reseal glass shower screens?
Yes, we do these often. The screen is resealed with anti-fungal silicone suited to bathrooms.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What glazing silicone looks like in Dedham Heath
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Castle House (about 0.5 miles north) are a reminder that the area around Dedham Heath has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Dedham Church of England Voluntary Controlled Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Parish Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
