The charm of classic sash windows in older homes can quickly turn into a headache when worn-out ropes, pulleys and weights leave them stuck or draughty. Instead of struggling with DIY repairs or ignoring the problem, consider partnering with a professional sash window repair company.

Experienced professionals have the tools and expertise to diagnose any hidden issues and bring your windows back to smooth functionality. Choosing the right company is key, and this blog will guide you through finding a trusted and experienced repairer to ensure your sash windows regain their timeless elegance and functionality.

What to Look For in a Sash Window Repair Company

When evaluating sash window repair companies, there are a few key indicators you should look for when searching for a reputable contractor. First, it’s important to choose a company dedicated to sash window repairs rather than general window or home repairs. Expertise with the intricacies of double-hung windows is vital for a lasting repair or restoration.

Be sure to look for companies that provide a range of repair options, such as rope replacement, weight rebuilding and reglazing, showcasing their versatility in addressing various sash window problems. The best contractors will also offer warranties covering labour and materials, demonstrating confidence in their work quality.

Lastly, responsive communication throughout the entire process, from initial estimate to job completion, is indicative of great service, signifying that the company is readily available to address any questions or concerns.

Tips for Choosing the Right Company

Get Recommendations from Friends

One of the simplest ways to ensure you hire a quality sash window repair company is to get a personal recommendation from a friend or neighbour who has used their services before. You may know people living on your street who have had repairs carried out on their windows who can advise you on trustworthy companies.

If you use a friend’s recommendation, you’ll have a good benchmark for the quality of work you can expect. If someone you know has had sash window draught proofing done, for instance, you can closely inspect their windows yourself at an unhurried pace. This allows you to verify the standard of work you want is possible by that company.

Verify Their Credentials

An important step when evaluating a sash window company is to verify their credentials, including proper licensing, insurance and worker qualifications. This due diligence goes a long way in ensuring you hire a reputable, professional company. Check that the business is insured, which protects you financially in case of an on-the-job accident or damage to your home.

Ask about any relevant certifications from industry associations and training programmes too. Knowing the technicians have the proper hands-on training gives confidence in the work quality. Taking time upfront to confirm these details shows a company’s commitment to professionalism. A company that readily provides documentation of credentials demonstrates transparency and reputability.

Get Multiple Quotes

When choosing a sash window repair company, it’s always advisable to get written estimates from at least three companies. Comparing multiple quotes allows you to evaluate pricing and service offerings, giving you a better basis for comparison.

When meeting with contractors, provide the same information about the project scope and your sash window restoration. Make sure to get quotes in writing with a detailed breakdown of parts, labour, fees and any additional costs. This will enable you to look for red flags like quotes that seem abnormally high or low compared to others. However, be wary of very lowball bids—there may be quality shortcuts in their workmanship.

Evaluate not just any cost differences but the level of detail and professionalism you experience. Discussing the project with several professionals lends helpful perspective in choosing the right sash window company for your home.

If I could clone you for all the other work we need to do over the next few years, I would! Thank you Mark for having such a good team in place. And huge thank you to Gary, Alex, John and Glen for taking such care of our windows and giving them what they needed after years (decades?) of neglect. Your attention to detail and 'doing it right' was very much appreciated, and your ability to solve problems was awesome. Helen & Tim, Godalming

Amazing service from start to finish, no issues and no drama. The name Sash Window Experts is well chosen. Mark and his team - Gary and John were extremely helpful and professional and the end product - new sash sound proof double glaze windows upstairs and the kitchen triple sash window restored was top quality. I am very grateful to Sash Window Experts.
Amy Clarke
Cannot fault Mark and his team. We replaced the original sashes to our 1890's home with new like-for-like hardwood double glazed sash windows, and apart from being warmer, quieter, cleaner and altogether much smarter, you really wouldn't tell the difference - an amazing feat! They are absolutely beautiful windows, so well crafted and fitted, and the restoration of rot on the original box is imperceptible. Gary was friendly, clean, professional, and safe throughout the fitting, and very thoughtful in causing minimal disruption to the home. Absolutely thrilled with everything from the service to the price to the final finish. Delighted with them. Would recommend in a heartbeat.
Alison Fordham
We were nervous about getting our Victorian French windows restored and had received a ridiculously high quote. Sash Window Experts came in at a good price, gave a timeframe that worked with our schedule and did a great job. All as promised. The fitter, Gary, put the doors back in with great care and took time made sure they worked smoothly and also discussed any queries with us. Definitely made the job value for money. Very happy customers! We are looking forward to beign able to open our doors again and enjoy the garden. Thank you Mark and Co!

Our house is Edwardian and has the original sash windows from 1906. I really want to make sure that any double glazed windows did not look out of place - so the woodwork, including the side bars etc should still be very thin to match the originals. I was fearing ending up with fat wooden bars but Mark took me to see a previous customer and I was happy to see the woodwork there and it put my mind at rest. We went for the thin Krypton windows. Now the windows are in they look very good and match very well. To be fair to everybody, we will not know until the winter how well they remedy our warmth and condensation issues in the house but are confident we made the right choice. Other suppliers would not do separate window panes and instead would only do a large window with a false wooden strip down the middle to make them look like two. We did not want that. The carpenters, Steve and Gary turned up on time (early actually) and got on with the job very efficiently and left no mess behind. I am very happy with the company and the windows.
Natasha Birley
Mark and his team are amazing. They restored our sash windows and doors. Mark is really knowledgeable and passionate and explained the process to me so I knew exactly what they would be doing. Once the work commenced I was amazed by how well they draft proofed the windows. They took so much care and the guys were polite, tidy, timely and a joy to have around. I would absolutely recommend the team to anyone thinking of restoring their windows, they look AMAZING!
