"Brian LaValle is a God Send!! Bought my home for under 20k and Brian has done everything from the basement to the roof!!! Drive by and Look at It. 705 Lundy St Streator. It sat for 5 1/2 years after a destructive foreclosure. There was no bathroom! Everyone Loves my bathroom now. The house looks Modern and heÃ¢Â Â s SO professional and comfortable and has been working on my home for well over a year so we pitched him keys to the house. I slept in the other day while him and his crew, always making sure my cats donÃ¢Â Â t get out, installed my laundry room floor. Never thought something like that could happen! Grade A work! Im So Proud of my house! This guy Checks My House to assure itÃ¢Â Â s sound and safe! The addition was attached to the original house. My roof was stressed and leaking. He Ã¢Â Â tiedÃ¢Â Â (their lingo) the 2 lil houses together. Now IÃ¢Â Â m saving up for him to do the roof. I flipped and remodeled 4 homes of my own when I was younger. This guy is the best. I humbly admit. Brian LaValle 815-674-8152"

"Amanda was really very good! At first I was very skeptical, thinking why did I pay money to just speak with someone on the phone about my kitchen remodel project... but after just a few minutes of her addressing some of the issues/questions I emailed to her earlier, I knew it was worth it. It was very clear that she knew her business and she gave me several ideas that I had not even thought about. I told her that I would definitely recommend her to friends and I will very likely use her again myself for my next home project!
