Rated 5 out of 5 by from Dealer has great customer service Glen, at Johnson Home Improvement, was great to work with! He was professional, and made us feel comfortable during the process of measuring, ordering and installing our new windows. If we had questions he responded promptly. Daryl, our installer, did a great job and the windows look beautiful! He is also very pleasant to work with. Thank you! We have already recommended Johnson Home Improvement to family and friends!

Rated 5 out of 5 by from Great workmanship; friendly, responsive customer service Johnson Home Improvement replaced all our windows about eight years ago, so it was a no-brainer to ask them to replace one that we wanted in a different configuration. We asked for the same installer who had done an excellent job before. He turned out not to be available at the last minute, and the replacement was just as good. Personable folks. Local business. I will use them again (if necessary!) and certainly recommend them to friends.

Rated 5 out of 5 by from I could not have asked for a better experience.

Rated 5 out of 5 by from Professional with attention to every detail from the initial estimate to final completion. We had eight windows of various sizes and a customer supplied storm door installed by a very organized system, which complimented the Milgard product. My wife is very happy with a finished project we have been talking about for some time. The only regret we have is that we waited so long to have the upgrade to our old windows. Thank you to a great crew at Johnson Home Improvement.

Rated 5 out of 5 by from Competent staff Understood the customer, a rare thing these days. Did not try to sell something we did not need. Listened to the customer,... knows the customer pays the bills. Most people in customer service do not get that, they say they do but after a few looks on their Iphone to check their Facebook in the middle of a meeting....they do not. These guys understood our needs and did what they said they would do.... and then some.

Rated 5 out of 5 by from Very Satisfied Johnson Home Improvement was an outstanding choice for a complete window and door replacement in our 38 year old residence. We had 14 replacement windows, 2 French doors, and one slider installed. We chose the Ultra fiberglass series. We had several bids and Johnson was by far the most competitive. We were given a tour of the local Milgard showroom by Glenn who explained in length the relative benefits of the available window choices. The installers were obvious professionals and daily cleanup meant no interruptions in our daily household routine.

Rated 5 out of 5 by from Excellent service from beginning to end. the person doing the measurements had excellent ideas for minor changes in window design--all of which I chose to use. Window installation was done as planned. Installer was thorough, competent, on time, and professional. Everything was left clean. I could not have asked for better service.

Rated 5 out of 5 by from Glenn and his crew were great from start to finish I chose Johnson Home Improvement from three quotes, all were good but Glenn gave the best advice (and was competitive in price). His crew showed up when scheduled, worked effectively around a couple of unexpected glitches, and kept me informed of their progress. I am quite pleased with the results in all regards. Outstanding.

Rated 5 out of 5 by from We love the windows and we are happy with the service Glenn and his crews provide. This is the second time we've had Johnson Home Improvement provide us with windows and the third time we've bought Milgard windows. We love the product and we really appreciate that Glenn is so personable and professional. We have recommended him and will continue to do so.

Rated 5 out of 5 by from Attention to detail makes them great! Johnson Home Improvement went above and beyond. Glenn and his staff are amazing, patient, and easy to work with. Their attention to detail and quality work proves that they care more about customer satisfaction and pride in their work than about just making money. They did a great job replacing 13 windows in my house, they were priced competitively and they made sure the job would be done right. This was the only project on this house that did not have a problem. I believe it was the staff's expertise and quality work that made that possible.

Rated 5 out of 5 by from A professional job every time. In the world of finding reputable professionals to work on your home--your biggest asset--it can be hit and miss, with lots of frustration and disappointment. Johnson Home Improvement never disappoints. Professionals from the owner to the installers. You can't go wrong.

Rated 5 out of 5 by from Original windows and glass doors in my 1973 house were replaced. 10 windows. 2 oversized sliders. 5 windows & sliders tempered glass. All UV24. his company was great to work with. I would say the best contractor I’ve worked with in the Portland area. Glenn Johnson came out to price the job. He was really nice and fair . He made great recommendations - things the other two bidding on the job did not consider. He recommended areas where I could cut cost and where it made sense to upgrade. The upgrades ended up saving me money because I get a better rebate from the Energy Trust. Jeff and Levi a wonderful father/son team did the work. Jeff is a master carpenter – he enlarged the openings by 1 foot in height for two of my bedrooms. I am so glad I did that – it looks amazing!! More light and gives my house a new house feel. Jeff and Levi were extremely professional, very competent, and pleasant to have around. They arrived on time every day and worked really hard. They were very respectful of my property and very neat. People you can trust in your home. They worked during the heatwave we were having – but didn’t let it slow the job down. Everyone I interacted with at Johnson Home Improvement was great. Glenn has had people working for him for a long time (Jeff @20 years) , (Arlene office manager @10 years. He speaks very highly of his employees and now I know why. They know their stuff. Every single one of them great to work with. I paid the balance at the completion of the job and immediately – within 2 days – received a package that contained the Energy Trust application filled out and all the supporting paperwork. All I needed to do was sign and send in. This company is a pleasure to work with. If you are thinking of replacing your windows and glass doors – I highly recommend them. I interviewed 3 companies and went with them and I’m glad I did.

Rated 5 out of 5 by from Johnson Home Improvement a Lifesaver After receiving estimates for repairing our son's broken bedroom window in the range of $1300+--Johnson Home Improvement told us that we could do a fix that would cost a mere fraction of replacement (others didn't give us the fix option, only replacement). While we know a costlier repair would bring the window back to 100%, for now we just needed the window to open and close and Johnson heard our needs! And fixed other windows with same issue. When it does come time to replace the glass or the entire windows you can be sure we'll go to Johnson because they were honest and helpful and didn't try and foist an unnecessarily costly job on us!
