Rated 5 out of 5 by from Friendly, no "bull" and easy to work with. We used Johnson Home Improvement in the past (~2007 or 2008) for installation of Milgard windows and doors. That work was very well done and everyone on the job was courteous and professional. If we needed to make changes or corrections to the job they were ready and able. When problems came up they did not hesitate to talk us through them and help us find a solution. Those windows are still performing as well today as they did ten years ago when they were installed. For the latest installation, which was for a bay window, we have the same assessment. The work was done quickly and professionally and I have no doubt that the window will be performing as well in ten years as it is today.

Rated 5 out of 5 by from Beautiful windows and Great Customer Service!! We have dealt with Johnson Home Improvements on 4 different occasions regarding installing Milgard vinyl windows and couldn't be happier. Glen came to our home and explained all about the windows and the process of the installation. Daryl did an outstanding job as usual with the installation and now we are finally complete with our entire house, which was built in 1966 and has some pretty big windows to replace. I would recommend Johnson Home Improvement and Milgard Windows to anyone looking to upgrade their windows and be totally satisfied.

Rated 5 out of 5 by from Excellent overall service. Very good installation experience. Installers were very clean and professional. Kept me up to date on schedule and what they were doing. Moved items out of the way, and replaced them back where they found them -- except for two rooms on their last day. Guess they got in a hurry to leave. I'm a little dis-satisfied with one patio door installation. Installers left a 1/2 inch gap at the top. It's sealed from outer air, but you can see the screws; and it just looks a little shoddy.

Rated 5 out of 5 by from Perfect start to finish Johnson Home Improvement was quick with their estimate and helpful in advising which windows would serve us best. The office kept in touch on the status of our job start. We thought the price was reasonable. The installer was skilled and neat. The office completed the paperwork for Energy Trust credits for us. Good experience all around. And we love our windows!

Rated 5 out of 5 by from Reliably excellent work I have contracted Johnson Exteriors for the installation of various Milgard windows over the years, most recently for a large home renovation project. Each time I have been very pleased with their skill and service, especially their attention to details. I live in an architecturally significant home and these details are very important for maintaining the quality and appearance of my home. I highly recommend this dealer.

Rated 5 out of 5 by from They did work when they said they would. So often you work with contractors and the never seem to get the dates or times right. Johnsons did!! Easy to work with. Installers knew what they were doing.

Rated 5 out of 5 by from Excellent service! From the beginning to the end of this process of shopping for windows, my partner and I were very pleased and impressed with Johnson Home Improvement. Glen met with us and went through all of the Milgard products as well as explaining how the job would be done. We consulted three companies; Johnson Home Improvement was not only the lowest bid, but also the most professional in presentation. The job took five days (we replaced 60 year old windows!). Each day, the installer cleaned up thoroughly, explained to us where he was in the job, and installed every window perfectly!

Rated 5 out of 5 by from 3 Windows lost their seal Johnson Home Improvement to replace the glass units with Milgard and they were in and out in less than 3 hours. Everything clean inside and out. The windows were sparkling clean and too beautiful. My wife is staring at the original Windows saying, hmmmmm

Rated 5 out of 5 by from This dealer and installation was excellent from start to finish! We were referred to Johnson for our window replacement. Their bid was very competitive and the proposal was professional and friendly. We had to delay the installation due to a pre-existing commitment but the installer was there on the appointed day. He worked efficiently with no mess left behind and always explained his daily plan. There was an issue with Milgard's inability to supply the screens so there was a delay on the delivery of those but Johnson's worked tirelessly to speed up that process!

Rated 5 out of 5 by from The dealer has great customer service. Johnson Home improvement gave us the best advise on how we could reduce the road noise coming from our bedroom window. The quality and service they provided was above and beyond my expectations. I was highly impressed on how much the quite line series windows reduced the road noise by up to 85%.

Rated 5 out of 5 by from Johnson Home Improvement was professional and knowledgeable. Glenn came to our house to review what we wanted and to discuss the pros and cons of different windows. We decided to go with the casement windows to replace the sliding windows that were 22+ years old and out of alignment. Glenn offered to meet us at the Milgard showroom so we could see examples of the windows. When it was time for the installation, Peter and Joe did a great job installing and cleaning up, leaving everything in order at the end of the first day so that we could use the rooms where the windows were being installed (2 large windows), and then they returned the second day to complete the job. They were all professional and worked efficiently. We just had to wait a few weeks for two screens which were damaged in the original order which Milgard needed to make again. We would use Johnson Home Improvement for window replacement in the future.

Rated 5 out of 5 by from Thorough throughout the entire process Recently bought this property. Replaced the aluminum windows with Milgard vinyl windows. They look great. Daryl, the installation person was great, right down to the details. All of the trim work is mitered and painted to our specifications and everyone who has seen them has been complimentary.

Rated 5 out of 5 by from Most Professional Workers Ever These workers are the most efficient and professional I have ever encountered. They show up on time, do the work they're hired to do and clean up afterwards. I would highly recommend them to anyone who asked me.

Rated 5 out of 5 by from Two thumbs up! I had a prior quote before Johnson Home Improvement came. JHI quote turned out considerably less. Also, I had a large oversize window and the first company said they would have to split it into 3 windows which I felt was okay, but I was disappointed. However JHI thought he could do it with one window. After checking with Milgard, they said they could do it. I was very pleased. When the parts came in they installed the two windows in one day and left the premises clean. the installer said it was the largest window he had installed in 20 years of installing. Very happy with results.

Rated 4 out of 5 by from Job well done. My house had windows from "heck", as one contractor put it and several contractors would not bid on the project. Glen Johnson understood the situation and gave me confidence they could do the job right. The interior side of the windows maintained the original charm of my house.

Rated 5 out of 5 by from Totally professional service. After having 3 bids, I chose Johnson Home Improvement to install my replacement windows. Have a 1929, stucco, 2 story home. Glenn came out and was knowledgeable and helpful in helping me choose which windows would work best with the style of my house. The cost was competitive with the other bids, so I went with Johnson. The work was done as planned, no fuss, polite workers, great clean up, leaving me no problems.

Rated 5 out of 5 by from Complete Excellence, Start to Finish! Glenn Johnson and his team just finished replacing all 23 of my 26-year-old windows with new Milgards, and it was an experience that couldn't have been better. Glenn was great at helping me choose from Milgard's many options, and Laura somehow coped with the record-breakingly rainy Oregon winter and spring to get my work scheduled. The installation was done entirely by Darrell, without a doubt the best craftsman/artisan I've ever met. He was truly wonderful: very organized, completely dedicated to an outcome of the highest quality, very good at finding solutions to complications, highly knowledgeable regarding Milgard products and installations, totally reliable, and meticulous. Every window was fully protected from the weather during his work, every work area was left entirely clean and orderly at the end of his work day, and he was very willing to work around my day-to-day business schedule in my home office. I simply couldn't be happier. One of the best purchases of my life! Thanks to everyone involved, and to Milgard to products that the company stands behind 100%.
