Enhancing Thermal Insulation

One significant reason to replace wooden window glass is to enhance thermal insulation within your home. Older windows often lack proper insulation, allowing heat to escape during winters and infiltrate during summers.

Upgrading to modern, energy-efficient glass can significantly reduce your energy bills by maintaining a stable indoor temperature. These advanced glasses, equipped with low-emissivity coatings, reflect heat back into the room, keeping your home warm in winter and cool in summer.

Mitigating Noise Disturbance

Another compelling reason to replace wooden window glass is the mitigation of noise disturbance. Living in a noisy neighbourhood or near a busy street can be disruptive, affecting your peace and well-being.

Upgrading your windows to double or triple-pane glass with acoustic insulation properties can significantly reduce outside noise, creating a quieter and more serene living environment. Whether it’s traffic sounds, barking dogs, or loud neighbours, the right glass can provide much-needed tranquillity.

Improving Security Measures

Security is paramount for any homeowner. Wooden window glass, especially if aged, might be fragile and susceptible to break-ins. Upgrading to laminated or toughened glass enhances the security of your home.

These glasses are designed to withstand impact, making it difficult for intruders to gain access. Additionally, reinforced frames and advanced locking mechanisms further fortify your windows, ensuring the safety of your loved ones and belongings.

Comparing Glass Replacement with Full Window Replacement

When considering upgrading your windows, it’s essential to weigh the options of glass replacement versus full window replacement. Glass replacement involves replacing only the glass panes while retaining the existing frames. This option is cost-effective and environmentally friendly, reducing waste by reusing the frames.

On the other hand, full window replacement involves installing entirely new windows, including frames and glass. While this option provides a fresh look and might offer additional features, it is more expensive and labour-intensive. Assess your specific needs and budget constraints to determine the most suitable choice for your home.

Addressing the Issue of Aging Windows

Ageing windows pose numerous problems, from drafts and condensation to difficulty in operation. Wooden frames, in particular, are prone to rot and decay over time, compromising the structural integrity of your windows.

Replacing the glass in ageing windows can breathe new life into them, improving functionality and aesthetics. Additionally, it allows you to incorporate modern technologies, such as energy-efficient coatings and UV protection, ensuring your windows meet contemporary standards of performance and durability.

Seeking a Long-Term Solution

Investing in high-quality window glass replacement provides a long-term solution to various issues associated with ageing and inefficient windows. Modern glass technologies, combined with sturdy frames, can significantly extend the lifespan of your windows.

Regular maintenance, such as cleaning and lubricating moving parts, ensures optimal performance over the years. By opting for durable materials and professional installation, you can enjoy the benefits of your investment for decades, enhancing the overall value and comfort of your home.

How do you put glass in a wooden window?

To install glass in a wooden window, the Sash Window Refurbish team would begin by measuring the dimensions of the opening. Then, we cut the glass to fit these measurements precisely, making sure it’s the correct size. Next, apply a bead of caulk or glazing compound around the frame’s perimeter. Gently, press the glass into place and secure it with glazier’s points to keep it in position. Finally, apply another layer of caulk or compound to seal the glass completely, ensuring there are no gaps and preventing drafts from entering. Our contact page.

How do you replace the glass in a double-pane wood window?

We start by carefully removing the window sash. After removing the sash, take out the broken glass, making sure not to damage the window frame in the process. Then measured the dimensions accurately and ordered a replacement double-pane glass unit. Once the new unit arrives, install it into the sash, ensuring it fits snugly and securely. Finally, reseal the window using caulk and carefully reinstall the sash back into the frame, completing the replacement process. Our contact page.

Is it cheaper to replace the glass or the whole window?

The cost-effectiveness depends on the extent of the damage. If only the glass is damaged, replacing just the glass is usually cheaper than installing a whole new window. However, if the window frame is deteriorating or the design is outdated, opting for a complete window replacement might be more practical in the long run, as it ensures better insulation and energy efficiency. Consider consulting a professional to assess the situation and provide the most suitable solution.

My technician Andrew replaced all my sash windows that had rotten sills. Accessing the rotten sills was not an easy task. He explained to me what needed to be done in order to fix the problem. He is a great person and I’m happy that he was the one who did the job. He is reliable, tidy, friendly and very professional. I highly recommend him.



I hired Andrew and Alex a while back to repair my damaged sash windows. They were was very considerate and very patient as he did his job. A few days ago, I had another problem with one of my sash lock keys and I called him again to come and fix the problem. I’m very impressed that Liam responded quickly and he not only fixed the problem but he also gave me a spare key. What a great after sales service!

I’m very impressed with the new windows that Andrew installed and also the reconditioning job that he did on other sash windows. The quality of his work is by far more superior than what we got when we hired another company a few years back. We will certainly hire him again if any window work arises

Our decorator referred us to Andrew because some of the work needed a window expert. Andrew together with our decorator did a fantastic job. The work was done efficiently and to the highest standards. Andrew is understanding, committed and very professional. I recommend him without any hesitation.

Alex did a great job in fixing windows in our terraced house. The windows were broken, frames damaged and the wood was also rotten. Alex's job was high quality and he did it pretty fast. I was also very impressed that he was considerate of my son’s asthma condition and maintained cleanliness. Top work.



Andrew just recently replaced three sash windows in my Edwardian house. He also repaired and replaced some sills and draught proofed three windows. In addition to that, he also did some carpentry work. What I like the most about Liam is that he did a clean job. He is very professional and always updated me about the timescales and costs. He also did his job with minimal disruptions. I highly recommend him.
