Customer Reviews

“From start to finish, A1 Windows did an excellent job. The work performed to install two new sliding doors for our home was tremendous and was a total A1 team effort! The final product was exactly what we were looking for, all at a very competitive price! We felt the experience exceeded our expectations and would happily recommend or contact them again for any future projects on our home. Great job, guys! :)”

“We were happy with the service, communication, and follow-through. The salesperson we spoke to was informative and took the time to recognise our needs and provide various options. The installers were careful in removing the existing windows and cleaned up thoroughly after installing the new replacement windows. Our experience has been stress-free due to the exceptional customer service, and we would use them again for future home renovations.”

“I don't regularly submit reviews; however, I felt compelled to share that I thought that the crew were outstanding. They arrived early and were polite. They took great pride in their work as they were very thorough, regular communication and answering any questions we had, super professional. I cannot stress enough how refreshing this was, from the beginning of the installation to the end.”

“Renovations are a stressful and overwhelming task to undertake. You don’t know when things will go south and really need to be able to depend on the people you’ve chosen to help you. If you select Windows A-1 for your renovation, you will not be disappointed.”

“We are impressed with the product, installation and crew. In this day and age, we are quick to criticise but forget to praise when everything goes well. The crew were efficient, fast and left everything spotless. The cost was as budgeted and the work completed on time. Besides making our home incredibly warmer, we have really noticed how much quieter it is. The street noise has decreased immeasurably.

We would be happy to recommend your company to potential customers and have already done so with the neighbours and friends.”

“We were looking to replace our windows and patio door as they are quite old, so we hired this service after seeing good reviews about this company on the internet.

“Where other companies were just giving quotes over the phone, Rob from A-1 Windows agreed to give us an in-person quote. His personalised approach and excellent customer service were one of the main reasons why we decided to go with them. Mani and Ranjit were very considerate and professional and did an excellent job installing our two windows. They were careful to protect our flooring and did a thorough clean-up afterwards. COVID-19 protocols were followed, and they were in and out in record time. Overall, we are very happy with the price, the work, and our decision.”

“Jatin, Mandeep and Ryan came to my house today to install 19 windows. They have done a superb job! They have worked efficiently and quickly, finishing the entire job in one day. They have been very pleasant and easy to work with. They have also done a great job cleaning up afterwards. My house looks like new again! I heartily recommend A1 Windows and this amazing team. Thank you, Randy, Robert - who did all the measurements and had infinite patience - and all those at A1 Windows!”
