A very competitive quote for replacing 2 x large bay windows, side window and installing new French doors. Extremely thorough and professional with no hard sell. Fitting took place over 3 days by two installers who worked non-stop from the minute they arrived. Despite some challenging old Victorian brick-work and non-straight walls, they did a fantastic job, both internally and externally. The finish was excellent and the difference it has made to both the noise level and thermal efficiency is incredible - it made us realise how bad the old windows actually were! Really can't fault the service - the price quoted was exactly what we paid and we're more than pleased with the results. Highly recommended.

1st independent windows came to quote and gave a competitive price. What impressed me most was the knowledge shown and willingness to answer all my questions. It was an easy decision to go with them. They lived up to expectation. Communication was excellent. They were on time and friendly, working hard to get the job done. I had a composite front door installed and a upvc with cat flap back door. Both were installed to High standard with beautiful finishing. Lovely team. Would highly recommend them.

We have used this family firm before and knew of the quality of their service and products. James the fitter arrived promptly and was a diligent worker. He left the site clean and tidy. We were particularly pleased with the way he offered suggestions to some additional trim which was required. A good product and good job well done.

Although work was delayed due to unforeseen circumstances, every effort was made to ensure work was completed satisfactorily. The door was fitted efficiently and the fitter ensured that I was familiar with the locking System. Further support was offered if needed. The finish surrounding the door is very good and adds to the attractiveness of the door.

The installation team came promptly on the day, and worked hard to keep to schedule. The windows are what we expected and are keeping us warm! Communication was easy and even a crack that happened during installation was remedied quickly and without fuss.

I used 1st Independent Windows recently to replace 7 windows at my flat to resolve condensation issues, the service was great from start to finish. Installation took 2 days and the flat was left clean and tidy.
