Biango Construction
Biango Construction
Biango Construction strives on giving all of our customers the best quality craftsmanship and pricing in the industry. Locally owned operated. We guarantee your satisfaction! Free estimates.
"I had Biango Construction complete a full gut renovation of my main floor powder room and laundry room/mudroom. This included a major change in layouts and moving walls, doors, HVAC, plumbing, gas lines, and electrical. I also had custom cabinets and hall tree built for the space. The final result is exceptional (see photos). While the time ended up taking longer than originally expected, it was worth it to have a trusted pro do the work and to deal with the permit process. The company was easy to work with, professional, and maintained a clean workspace across my house. All individuals working on my house with Nick Biango paid high attention to detail throughout the entire process. I would highly recommend Biango Construction to anyone doing renovations or wanting built-ins added to their home."

Specializing in Panel Upgrades, Panel Swaps, Emergency Services 24/7 availability. Installer of electric vehicle Charges. Locally owned & operated. Free quotes for new installations. Low diagnostic fees for troubleshooting and repairs. Preferred installer of Ford and Tesla electric vehicles.
"They combined two electrical boxes into one and had to move an outlet to slow for a longer panel. The guy did the work while my disabled husband was home (he was unable to climb stairs and inspect the completed work). I came home after the guy left and had to move the old electrical panel that was sitting in front of my garage door. All the rest of the garbage was sitting in my garage. I was not happy, he told my husband he could not fit the trash in his car. When I looked at the completed job I saw he had retired the outlet and had a cord across the front of the panel box so it couldn’t be opened unless I unplugged the cord. What?!! And he also left his own personal trash in the basement. I was very upset and called the rep that had originally come to the house and he sent the same guy out the next day to fix it. I asked him to please take the old panel box and other trash he left and he said he didn’t have room in his car to take it. I was not happy with this company and would not recommend."
