I've had 16 windows replaced plus a patio door. I've asked quotes to more than 10 companies in Calgary and I've found Royal View Windows to be the most competitive. Before awarding the contract to them, I've asked Alex more detailed info about warranty and type of glass he'd be installing, he's been very detailed in his reply, qualifying exactly the kind of products I would have installed. They kept the promise on the installation dates, did the job quickly, they cleaned everything behind them, left the house in perfect conditions. Alex is extremely nice to deal with, there's wonderful communication, he's very responsive and honestly I couldn't be happier to have chosen his company for this job. The cost saving compared to the second lowest bidder was significant and more than 60% cheaper than the highest bidders. Alex was very helpful with suggesting the type of window opening that would be ideal for my situation, also he cares a lot about the exterior aspect of the house and he does everything possible to leave the customer happy with the end product. Strongly recommended, you can't beat their price and quality! Thank you Alex!!
