Sash windows, a hallmark of classic architecture, exude timeless charm and elegance. To maintain their functionality, understanding their intricate mechanisms is crucial. This guide explores the process of repairing sash windows, focusing on those equipped with spiral balances.

By comprehending the role of springs and identifying common problems, gathering essential tools, and following a step-by-step repair process, you can restore your windows to their former glory.

Decoding the Mechanism of Sash Windows

Sash windows operate on a system of weights and pulleys, allowing seamless vertical movement. In the case of sash windows with spiral balances, the traditional counterweight mechanism is replaced by a spiral balance attached to the window frame. This spiral balance aids smooth movement, ensuring the window stays open when desired and closes securely.

The Function of Springs in Sash Windows

Springs, specifically spiral balances in this context, are pivotal components in sash windows. They provide the necessary counterbalance, facilitating effortless opening and closing. If these springs malfunction, the window might become difficult to move or remain stuck in a certain position. Understanding the signs of spring issues is crucial for timely repairs.

Spotting Common Issues with Sash Windows

Sash windows, regardless of their mechanism, encounter common problems over time. These issues include rattling panes, drafts, and difficulty in movement. With spiral balances, specific problems might arise, such as uneven window movement or the window not staying open. Identifying these issues is the first step toward effective repair.

Tools for Restoration

To embark on your sash window repair journey, it’s essential to assemble the right tools. For sash windows with spiral balances, a unique set of tools is required, including a spiral balance tensioning tool, a screwdriver, pliers, and lubricant. Safety equipment such as gloves and safety glasses are equally vital to protect yourself during the repair process.

Equipment for Sash Window Repair

  1. Spiral Balance Tensioning Tool: This specialized tool allows you to adjust the tension of the spiral balances accurately.
  2. Screwdriver: A screwdriver is necessary for removing screws and disassembling parts of the window.
  3. Pliers: Pliers come in handy for gripping and manipulating small components.
  4. Lubricant: Applying lubricant to the moving parts ensures smooth operation post-repair.

Safety Gear for Window Restoration

  1. Gloves: Protect your hands from sharp edges and debris with sturdy gloves.
  2. Safety Glasses: Safety glasses shield your eyes from dust and potential debris during the repair process.

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

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.
