"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

"The initial build went reasonably well. We did find problems which they did come back and fix. I noticed a railing support that was cracked. I was told that I must of done it, that was that. The plugs that cover the screw holes in the stairs are falling out. I looked for some at Home Depot, but couldn't find the right color. I still had Chase's cell #, so I texted him and asked if he could send me some plugs, and I would do it myself. No response. Tried again the next day, still no response. I'm not surprised. Aging the build was decent, price was higher than most. Now that nearly 2 years have gone by, and customer service should be anticipated, nothing. Never again."

"We recently completed a gut reno and second story addition. After engaging 10 different contractors, MP was the most communicative, interested, flexible and competitively priced. MP has a large in-house team of experts that work efficiently and adapt to the home owner’s needs and preferences. The employees worked 6 days a week and took great pride in their work. They were personally invested in our project and wanted to make it the home of our dreams. The team includes an amazing designer, Nataly, who helped with selecting finishes. The onsite foreman, Adriano, demonstrated expertise and kindness. Seichelle and Marco did an excellent job with operations, ordering materials and problem-solving. We have been back in our home for 10 months. Anytime I have an issue, Seichelle and the team have addressed it. They have gone above and beyond what is expected. We could not be more pleased with our project. We strongly recommend MP for your next project!"
