Rated 5 out of 5 by 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. August 13, 2015
Rated 5 out of 5 by 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. August 13, 2015
