The project included removing the original siding on my entire house, and replacing with Hardie Color Plus siding, which is painted at the factory. They also painted trim and my garage door to match. They custom fabricated decorative trim onto two gables. Also, they replaced a french door & transom with a very high quality french door, improving the look inside and out. Window World impressed me from my initial quotation through job completion. When I called for a bid, they came to my home the next day and their very knowledgeable salesman gave me a very accurate quote immediately. Their price was very reasonable, and I visited several homes with their siding work. I also called James Hardie to ensure their installers were high quality. Window World recommended Hardie Color Plus siding, which turned out to be an amazing product in appearance, and it has an excellent warranty. Window World of Portland’s co-owner,John Rouse, visited regularly and had Hardie reps visit the job in each phase, and they used the highest quality materials. They also installed with meticulous care and craftsmanship. I have curved windows and I was amazed at how they cut Hardie Trim and Siding to fit perfectly. The installers were extremely helpful, minimizing interference to our home & garage throughout. They cleaned up at the end of each day and tarped materials to prevent them from damage. I didn't have any problems but I did have questions and concerns, and the owner of the company gave me his cell phone and immediately responded and acted on all my questions and requests immediately. I have already recommend Window World of Portland for siding and doors to my friends. For a company named Window World, they certainly do a outstanding job on siding and doors. Window World is a franchise, which is an advantage because they can negotiate low prices on materials from manufacturers. However, your experience may vary depending on your franchisee. This experience reflects Window World of Portland, and in particular, the professionalism of its co-owner John Rouse.
