Retrofit double glazing
Make a big difference to the warmth and quietness of your home by having us retrofit double glazed windows and doors into your existing frames
At Well Hung Joinery, we believe the best way to retrofit double glazing is to replace old single pane timber doors and window sashes with new custom made ones that can carry the weight of the new glass.
This complex, specialist job requires the skill of qualified joiners who are experienced in double glazing timber doors and windows. From the initial consultation through to manufacture and installation, you get that expertise from us.
All new doors and sashes are made from a selection of premium materials, such as Cedar, Pine, Accoya, Thermofixx, along with a wide selection of different glass types, and glazed using the latest glazing design and technology. They come fully primed and can be topcoated in our factory. Heavy duty draft seals and stainless steel hinges are fitted during installation.
Following is our retrofit double glazing process. Please have a read and then contact us to get on your way to a warmer, drier, quieter home.
How we work
1. Initial consultation
Give us a call on 04 494 7230 to set up a time for one of our sales team to come to your home. When they visit, they’ll measure your doors and windows, inspect the existing frames, and discuss the different types of glass and infills available.
For example, using argon gas between the glass can reduce heat loss more than air alone. And adding thermally insulating glass, known as low-E glass, can further enhance double glazing’s thermal properties because it traps heat inside the room.
Your sales person will explain all these options to you before giving you a written quote which itemises each room with its cost. When you accept the quote, we begin making your new doors or sashes at our Wellington factory.
2. Manufacture
We use premium grade cedar for all external joinery because it’s a stable and weather resistant timber. Once the doors and sashes are made, we order the double glazing units from our supplier. When they arrive, they’re glazed by our professional team of glaziers.
3. Installation
When your joinery is ready, we’ll contact you to arrange an installation time. We have a team of specialist installers who are dedicated to carrying out installations, and ensure you get the best final result.
Old sashes and doors are removed and the new ones are fitted into their place. New hinges and new or existing hardware is fitted as well. We make any alterations necessary to make sure everything fits tightly. Your sashes and doors are ready to be painted or stained.
Now you can enjoy the huge benefits of your new double glazed door and sashes, knowing they’ve been made and installed to the best possible standards.
A word about condensation
Condensation is generally recognised as being caused by the moisture in your home and the difference in temperature between the outside and the inside. The air inside your home contains moisture from your day-to-day activities. Showers, cooking and even breathing will add moisture.
When the inside temperature cools down, the air cannot hold as much water vapour. The result is that the water vapour condenses as a liquid and becomes visible particularly on cold surfaces such as windows.
By insulating your windows with double glazing, you reduce the likelihood of condensation forming on the inside surface of the glass. The moisture is still present in your home though, which is why it is important to also have a well-ventilated house.
Adding in low-E glass, which is a superior, high performance double glazing, will help retain the heat inside your home even more than standard double glazing will. Low-E glass works by reflecting the inside warmth back inside the room.
Because of the nature of this high performing glass, the outside pane can get cold overnight, and in certain extreme situations, can have condensation form on it. This is not considered a defect of the glass, but is actually a sign that this high performing glass is doing its job by keeping the warmth inside the room. As the exterior temperature rises, this condensation should clear up.
