"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."

Subcontractors questions, answered by experts

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

Depending on your structure, you may not need planning permission. Major excavation, anything that changes the external appearance of your home, or any construction that will affect your neighbors will need planning permission. However, no planning permission is required if you’re just converting an existing space into a root cellar.

There are several different steps in the pole barn building process. First, you’ll need construction plans, which you’ll use to obtain permits. Then, you can clear the land so it’s suitable for building and installing the foundation. Your contractor will frame the barn using large poles, then rough in the plumbing and electricity (if your barn has those elements) before finishing the interior, adding siding, and installing the roof. 

After that, they’ll finish up the electrical work and plumbing and add your windows and doors. You may have a few other finishing jobs to do like painting or waterproofing.

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.
