Personalized, Quality Service from Sunrooms Northwest
Have you ever heard the phrase often used in the work world: “It’s not personal, it’s just business”?
At Sunrooms Northwest, serving the Pacific Northwest, we believe it’s never “just business” – it’s always personal. So when you invite us into your home to make an improvement for your family, it’s a matter of personal pride as your neighbor that you get exactly what you want. It’s your home and our good name in our community. That’s why our number one priority is to give you the best quality products and the kind of customer service you don’t find anymore. And we back it all with a written warranty that we know you won’t need – but it’s there if you do.
Communication and Quality
We have a “do whatever it takes” work ethic. That starts with regular phone calls to keep you involved and informed at every step. And it includes being available to you whenever you need us, even long after the project is done.Your sunroom, installed by Sunrooms Northwest, is the strongest, highest quality thermal sunroom available in the Pacific Northwest market today, built by TEMO, a family-owned American manufacturer making sunrooms since 1970. TEMO engineers these rooms to structural standards well beyond anything a Northwest winter asks of them – sustained rain, wind off the water, and the occasional heavy snow load. When we discovered TEMO, we knew we had found the only sunroom we could trust with our name and you could trust for your family.
Customer Reviews & Testimonials
★★★★★When our 40 year old sunroom was destroyed in a storm a few years ago, we hired Sunrooms Northwest to replace it. After getting quotes from several vendors, we felt that the product they were offering was better than the other vendors, and the price was very reasonable. We were very happy with the work they did – happy enough that a couple years later we hired them to replace all of our other windows. The windows were very good quality, and the price was very competitive. While the process and getting all the parts ordered takes time, once parts arrived they were efficient and professional. Tyler and his team are great to work with, and they do quality work. Punch list items were dealt with quickly, and we felt great about the whole process. A contractor who does good work, reliably, at a good price is a rare treasure. I would absolutely recommend Sunrooms Northwest to other homeowners for sunroom or window work.
★★★★★We replaced an old sunroom that was starting to fail. Sunrooms Northwest came to our home, reviewed our existing sunroom site and then gave us an estimate to replace the room and update our deck and stairs to the sunroom. We liked what they offered an accepted their quote. When their staff arrived to remove our old sunroom, they explained the process, and then proceeded to remove and erect our new sunroom. They were careful of our property, kept us informed of their activities, and proceeded with the project. We didn't watch much of the work, but that which I did watch, showed an amazing level of expertise, and their attention to detail was amazing. The project is now done, and we are starting to enjoy our new sunroom. I recommend anyone looking for a sunroom to contact Sunrooms Northwest to see what they can do for your needs. Emmett Richards
★★★★★We hired them for our mini sunroom. They were efficient, the materials were high quality and the cost was in the mid range. They took care of the city permits and made sure we have all the materials delivered on time. Fast forward 2 years we called them to fix a leakage issue in our sunroom and they did not respond. Will update this thread if they do. They did respond and send maintenance guys. Great service.
★★★★★We have worked with Alex and his team about 18 months ago to build Sunroom in our back yard. They did a great job of delivering a great sunroom. After months of using the sunroom, it looks like brand new. We are super happy about the sunroom and their work.
★★★★★Overall my husband and I are very happy with our experience. They were one of several contractors we had come out to give us an estimate to replace our sunroom and no one else said yes or their estimate was extremely high.They lost a star because the phone number on their website leads to a call center where the people have no clue what is going on in the business. The direct contact we did have kept promising we would be put on the schedule and that the owner would call and he never did. Eventually, when we pushed for a commitment we got scheduled the next day. When they got here, everyone was extremely professional and friendly and they really knew what they were doing. We love the work they did and can see the quality. Sunrooms Northwest is definitely the way to go if you want a new sunroom or need one fixed. We are very grateful and happy to have found them!
★★★★★Sunrooms Northwest came out and build a new Trex deck and installed a patio cover. The work crew was great and cleaned up after they were done with the day's work, very professional and friendly!
★★★★★We cannot thank Sunrooms Northwest enough for installing our deck covers – we love them! This company has been THE BEST to work with out of all the installation contractors we have dealt with over the past 40+ years. Every single person has been exceptional, extremely competent and responsive, and very kind. Highly recommend Sunrooms Northwest.
★★★★★I worked with Alex at sunrooms Northwest and he is a super professional and an all-around great guy! I highly recommend this company to anybody that wants a very high-quality sunroom.
★★★★★I loved working with Sunrooms Northeast. They are very professional and Alex the sales point of contact was really very responsive to texts and calls. He answered all our questions promptly. Bob the owner is very experienced as well.
★★★★★I recently hired sunrooms Northwest to have a sunroom addition built to our house. All the people i interacted with, the people who came to build the sunroom,sales,customer care, all were very professional, honest and respectful. The construction was done cleanly, according to county standards, sturdy and on time. And it was exactly as we had imagined it will be. Expect around 4 months since the time you sign the agreement to actual build time because 1. Need to get permit from city or county 2. Need to order parts after permit is granted. Other than these 2 factors, which they communicated to us clearly, it will be done in time. I have attached some pictures
★★★★★Professionalism. This is the one word that describes them accurately. I worked with Dave and Bob, and the crews they brought along who built the sunroom for me. They were very friendly and helped me design the exact layout and connections I had in mind. The end result turned out very well! I would highly recommend them to anyone who is looking for building a sunroom.
