Sol Construction LLC (Handypro of Washington DC Metropolitan) is the worst contracting company I have ever worked with. Ali Soltani, the man in charge of my disability installation, was incredibly rude, aggressive/belligerent, and unwilling to compromise. I would never work with this man/company again. When asking him a question, he left my house abruptly and in his car. He was unprofessional throughout the work and a money-grabber. He made a mistake while installing the stairlift, was unwilling to admit it - blaming me for HIS mistake, and wanted to charge me extra to uninstall the stair lift. Furthermore, he wanted me to buy another product and his manual labor (doubling the charges). This is no way to have customer service for a disabled, elderly person. Furthermore, when the work was inspected by the county, all of his work was failed - not passed due to being deemed unsafe. The outdoor lift does not work now either, not that I'd want to use it in this dangerous fashion. If you want to get yelled at, get overcharged, or deal with removal of products and bringing in another contracting company to fix mistakes, this is the place for you. I wouldn't recommend anyone to use this company.
