"I had Modern Window put in a very large window right in the front of my house, a window that changes the entire look. They use ProVia products which are made here in the USA. This is not a ProVia review as they are the only reason my sanity is remotely intact after this ordeal. I was PROMISED by my salesman a clean, finished look. I have gotten nothing but the opposite. After the install I contacted the company due to the attached pictures of the "finished" product which was embarrassing and just shy of dangerous to my house. The roof was built right over top of my existing siding and caulked on. The shingles were not the right color which they had blamed on supply chain issues (They went to home Depot the day of install for them. I ordered the window and install with detailed instructions months prior) flashing was wavy, uneven, and had large gaps. Great for a fresh hornets nest. The roof was FAR from centered. And they've all but destroyed my landscaping. Oh yeah. I almost forgot I couldn't open the brand new window because it touched the roof. "okay sir we will fix it" I was scheduled a month out for them to redo it. Fine. Companies are busy. I get it. Well today they came to redo it. The hole in my siding? Too small. The frame of the roof? Split at almost every corner due to them not predrilling. The J-channel to keep water out? Wavy and uneven. Then it started to rain and the installers left saying the office would call me shortly to schedule them to come back leaving two gaping holes in the bottom of the roof. I'm beyond angry at this point. How does a company like that get 4.8 stars? Regular windows? If you don't know how to do the job hire somebody that can. If your wondering too the job was just shy of $9000. That doesn't like like $9000 to me. Don't waste your money, go with anybody else. Even a stranger that says they can do it, at least then you'll get what you pay for. UPDATE 9/14 Forgot to mention during install they tried to leave a ROTTED sil for this behemoth window to rest on to save a buck. Attached picture. Today after having left this review and leaving an angry E-Mail to the GM I was sent out a two man crew to "rectify" the issue. Rick, the owner had a conversation with me about what was expected and I told him the solution to the problem is to remove the overhang, cut the siding down larger, and replace the overhang adding J-channel for a clean, watertight, finished look. He told me that's not an option and instead we would have to figure out another solution. God bless Adam and Brandon for all of their hard work today making it to where at least now it looks like a professional FIXED a botched job. Granted I am still going to have to remove the overhang to reside my house and we had to get quite creative with the caulk, but hey. Now I won't get laughed at by my neighbors and it will keep the expensive new window dry for now. When the guys finished the mcgivered fix to an awful situation I had a conversation with Rick and he wanted to know if I was satisfied. I explained to him that I am not and for me to be satisfied the roof would have to had been redone to the correct size and J-channel flush all the way around. He said he's sorry and instead insulted me with a gift card for my wife and I to go to dinner. A gift card for those who don't know won't keep my window watertight or help me to not redo all their hard work when I need to redo my siding. Anyhow he asked that I take down this review. I will not, I do NOT recommend Modern Window to ANYONE. Especially not someone who won't babysit the guys and might look at a botched job and think it's all okay. It's all fun and games until it's raining inside after all. At this point I'm considering legal action for Deceit, Fraud, and Defective Construction Work as I know for a fact the framing is cracked, splitting, not flush to the wall, and I'm pretty sure the ONLY thing holding the weight of the window. Pretty sure bribery is frowned upon too. FIND ANOTHER CONTRACTOR!!!"

"I am sure that all positive reviews for this company are fake. Nothing that was promised to me was delivered. My siding project is still ongoing for over 1 month. Was told that it would be done in week. Had one rain day. They have system like this: 1) sales person who never installed anything he will promise you things that obviously are not true, 2) crew that is subcontracted but not Gunner, mine was driving for over 2 hours away, 3) person who oversees the project but has little control over anything, no supply, doesn't know the crew, crew does not listen to him, main office does not listen to him, 4) main office does not reply to you. They just tell me to talk to project manager who has no control. So you understand that if there are any issue you are on your own. Quality or work is not good. Many times I had to point to the crew what's wrong, planks are broken yet they were still installing it, caulking is done they way that I can do it better, they cut wires to awning etc"
