"We didn't really have windows installed (yet) but Renewal by Andersen did install a new back door for us which happens to have a very large window! The website did not have an option for door installation. In any case, we had our back door replaced by Renewal by Andersen. Our installers, Lincoln L. and Dylan K. did an excellent job. They were efficient and skillful. They also did a good job replacing the trim around the door as the old trim did not fit the new door. All in all the job was well done and our new door is vastly superior to the old one."

Honesty, real value, no pressure sales. Since 1997 we have been one of the most highly recommended window and door replacement companies for a reason. Super Service award winner every year since 2006, today we are still a small locally owned and operated company with integrity as our number one priority. The best installers, the most attentive and caring operations team combined with lifetime installation warranties are why our customers come back to us time and again.

"We had an amazing experience with Emerald City Energy Windows & Doors! They were very responsive to my calls, emails, and texts leading up to our installation and the installation was a breeze. Benaro and his team were on time, so kind to me and my kids, efficient and left the house looking like they had never been there. I was shocked at how quickly they got everything replaced and cleaned up! We are so pleased with the quality of the window and the service we received from start to finish. Look no further for your window needs, you have found the company you need in Emerald City Energy Windows and Doors!"

Windows questions, answered by experts

While clean windows don't automatically increase home value, they make your home look more attractive from the outside, and since the exterior is the first thing a potential buyer will see, it can help make a good first impression that paints the rest of your home in a positive light. Educated homebuyers will see that your home is well cared for if they see clean window tracks and sparkling window glass, which can contribute to an overall positive opinion of your property. Clean windows give the impression that the rest of the home—including systems and appliances—is probably well-kept, too.

Most standard windows can accommodate solar screens, but specialty shapes or non-standard frames may require custom solutions. It’s important to consult with a professional to ensure compatibility and proper fit for unique window designs. Arched, bay, and fabricated windows often need fabricated screens, which can increase costs and lead time.

Yes, egress windows must meet local building codes for size and accessibility. Professional installers ensure compliance.

Before purchasing, it’s good to weigh the pros and cons of vinyl windows. Vinyl windows offer several advantages over other types of windows. Vinyl windows are more affordable than most other window types, and they’re also very energy efficient. Vinyl windows are also low-maintenance, weather-resistant, and easy to install.

Windows can crack for various reasons. Common causes include aging glass, physical impact, and temperature stress. A less common reason is pressure changes, which are far less predictable. Pressure changes often happen because of poor window placement.
