Einar Johanson Insulation & Glass Einar Johanson Insulation and Glass, Inc. is one of the longest-operating, independently owned construction firms in Washington state. When Einar started the company over 51 years ago, it sold and installed insulation exclusively. Windows and doors were added a few years later, now making up all current sales and installations.

Einar has a simple, tried-and-true business philosophy: treat people fairly, provide good value, and don't use high pressure sales tactics. Einar extends a similar approach to his employees, many of whom have been with him for decades: treat them well, pay them a good salary with benefits, and it will return in loyalty and quality of work.

We had Einar Johanson Glass install new French sliding glass door off our kitchen nook. They did a wonderful job and I love sitting at our kitchen table looking outside now. The French Rails adds a bit more class and design than a regular slider. The company was fantastic to work with! They were thorough, detail oriented, on time, installed and cleaned up well and communicated effectively throughout the entire process. I highly recommend them!

We had new windows and a door installed in our 1960s home last spring. Over the years we've gotten to work with a few different contractors in home updates and this company is absolutely the most professional, straight forward, and easy to work with. Our windows fit the style of our home, are exactly what we expected and after the install not a speck of dust was left behind. I highly recommend this company!

Had a great experience with Einar Johanson for my window replacement! From estimate to installation, the employees were friendly, helpful, and did not pressure me at all. The installation crew was punctual and I really appreciate the way they protected my floors and rooms from dirt and dust. Would highly recommend! Service: Window installation

Great experience! Quality window replacements of a mid-century house. The whole process from proposal, measurements, installation, adjustments, and payment was professional and respectful. I will happily recommend to friends and family in the future.

We used Einar Johanson to replace all 24 windows plus a sliding glass door with new energy efficient LowE windows. We had a large garden window wall that we removed and the crew built an entirely new enclosure and frame for it. Everyone was extremely professional and the installation crew was top rate. I highly recommend Einar Johanson if you need windows replaced.

We just had a a few windows replaced by the wonderful team at Einar Johanson. We have a home from 1937 and they were so careful about properly fitting in the window and cordoning off the construction area to mitigate for lead paint. They left the place pristine and were highly skilled. We will definitely hire them again for future window needs. If I could give more than 5 stars, I would.

Our experience with Einar Johanson was outstanding. From the first phone call to the installation everything exceeded our expectations! Our neighbor recommended them. They replaced our condo windows and slider and we couldn't have asked for anyone to do a better job. They were timely, clean, and precise. The day of installation I felt comfortable leaving them alone in our condo.

I left so me and my kid wouldn't be in their way. They called me halfway through and then let me know when they were done and locked the door! When I arrived back they did a great job at cleanup. The door and windows are excellent quality.

Einar Johanson has a great reputation, and they were willing to do a small job for us, replacing 2 broken windows. We had trouble getting calls back from other companies. The person who did the estimate was very professional and not pushy at all. He explained the entire process and we received timely phone calls updating us throughout. The installers were so professional and careful.

I didn't realize I should have removed a bunch of breakables on a dresser near the window. They carefully moved everything well out of the way and cleaned up beautifully. We were pleased with all aspects of the job!

We used Einar Johanson last year to replace several very large window panes that had lost their seal. We'll be using them for another job this year. They were wonderful to work with! They were very professional and friendly to work with, really great at communicating with me, and very accommodating to the tricky details of my house and working through that. Definitely the most responsible window company I've come across with very impressive integrity and customer service. Call them!

We used Einar Johanson to replace nearly all of the windows in our house (in 2 phases) and we couldn't have asked for a better experience. Before replacing them, we got multiple bids and Einar Johanson was by far the most competitive. This, coupled with the fact that they are a small family owned business, made the decision easy for us. After getting all of the windows in our basement replaced by them, we contacted them about a year later to replace the windows upstairs.

We worked with the same people both times which I really appreciated; I think it says a lot about a company whose staff is consistent and long-lasting. We've been super happy with Einar Johanson and have recommended them to multiple people. Definitely the way to go if you're looking for new windows or doors!

Einar Johanson was the bright spot of our remodeling project. You were the only company who honored their commitments, both in scope of work and schedules, and the quality of that work was very good. For making our project just a bit easier and for providing results that are very satisfactory, I thank you!

I had two windows replaced in my condominium. Due to the construction of the building on a hillside the larger window was on the second floor. This required the use of a lift and ladders. The larger window measured 4 x 6 ft.

We had Brian, from Marysville, replace one of our picture windows. Wow, he was great. Professional, friendly, and good at what he does. He finished the job quickly, completely, and without any mess to clean up.

These guys were great! We had EJ replace 8 windows in our house. I had learned about them through a friend and added them to the list for bids. Their bid was right on par with the others, and Doug's customer service was top notch: no-pressure and very knowledgeable about their products.

We needed to replace our old metal windows as we were getting tired of cleaning the mold that would build up from all the moisture. We did our research, looking at four different windows companies and Einar Johanson beat the others in price for quality of product.

The installers were very careful when entering our home. They protected our floors and carpets, and made sure our furniture was safe during the window installation. It was nice to have someone care about our home.

Very professional from quote to installation. Installation was extremely fast and the workers left our yard/interior of the home very clean. Only one issue occurred during installation - a piece of rotted trim that we had quoted to be replaced was missed on the initial installation.

We selected Einar Johanson to replace the original wood windows of our 1929 home. Their crew, from the initial consultation and measurement process through to final installation, was outstanding. The installation was completed on schedule, and we have been enjoying our new windows (and reduced heating bills!) for almost a year now.
