"I have been in and out of a lot of new construction in Lake County, and the work stands out. The finishes are a real step above what you usually see, and the trim, cabinetry and tile were all clean and well executed. What impressed me most is that the house was fully custom, so nothing was pulled off a standard plan. Every detail had to be decided and built from scratch, and it still came out cohesive and thought through. The team was easy to deal with, responsive when questions came up, and they kept the job moving. If your are thinking about building custom in this area, It is highly suggested you to reach out to Icon Building Group."

"This pro did a great job! They completely renovated our 99 year old home. They tore out and replaced everything inside, HVAC, plumbing, electrical and even the old, out of code wall studs that were discovered when the walls were taken out. They replaced all doors and windows as well to give a seamless look inside and out. They also added needed accessibility features. Outside, Imperial 1 replaced siding on the back porch and garage, replaced the garage roof, replaced a sagging sidewalk, and cleaned up the exterior bricks. They worked with our lender's consultant, appraisers, inspectors and the village building department to give us a beautiful new home on time and within budget. The owner was in contact throughout the process and continues to answer questions as they come up. The owner is honest and trustworthy. I highly recommend this pro."

"We had an excellent experience working with Robert Anthony from start to finish. They were professional, responsive, and incredibly detail-oriented throughout our kitchen remodel. His team completed our renovation on time, kept the workspace clean, and communicated with us every step of the way. The quality of the craftsmanship exceeded our expectations, and you can truly tell they take pride in their work. They transformed our kitcjen beautifully and made the entire process smooth and stress-free for my family. We are beyond happy with our kitchen and we couldn’t recommended him more."

"We are moving and placing our house on the market. We have a full finished basement that was completed 30 years ago and felt that the ceiling need some attention and upgrade to be more current standars. We met with Angelo of AP Builder & General Contractor about our desire to replace the acoustic ceiling tiles. As we looked things over we discussed the lighting situation as well which was also 30 years old and decided that replacing the lighting with current LED lighting would show off the basement better to prospective buyers. We got a quote within a day and then they were patient to wait until we had some other decisions on the sale made before we officially contracted. Once we signed the contact they had the materials secured, team assigned and the project complete in a week which was sooner than originally estimated to complete the job. I highly recommend Angelo and his team at AP Building & General Contractor LLC"

Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.
You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website.
Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:
In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
