    We desperately needed a new driveway and after contacting 3 local concrete companies we decided on…read more4way Cement and couldn't be happier. Josh was friendly, professional and knowledgeable and answered all our questions and provided a reasonable quote. Not only did we need a new driveway but we also decided on replacing the sidewalk and adding a back yard patio. Juan, the owner and his entire crew were so friendly and professional and really take pride in their work. October 28,2024 was tear out day and November 1, 2024 was pouring the concrete day. Everything went as scheduled and looks really great and definitely added value and curb appeal to our home. We can't wait to get back out there and fill in the surrounding areas with dirt and grass seed and finally get to use our stored patio furnishings. If you need concrete work PLEASE give them a call and I'm sure you will not be disappointed. UPDATED 11/17/2024 two weeks after my initial review. I emailed Juan the owner of 4WAY cement twice now since pouring our driveway on 11/1/2024 regarding the concrete sealer. He said he was going to seal the new driveway on Tuesday 11/5/2024 and both my emails have gone unanswered and the driveway still not sealed as of 11/17/2024. I may be dropping a star or two if our driveway isn't sealed by month's end. Stay tuned!

They were patient while we got competitive bids and waited for board approval. Dean was on site doing work as promised the week after receiving the go ahead and deposit. He did a great job and went above and beyond in completing the work by replacing a missing brick on the hearth. Very happy with the workmanship, attention to detail and friendly communication throughout the process.

    Exceptional Service with Integrity and Expertise…read more Dean and the team at Detroit City Sweep exceeded every expectation. From the moment he arrived for the service call, his professionalism, knowledge, and attention to detail were evident. He took the time to thoroughly inspect the chimney, clearly explain the repair recommendations, and answer every question without ever making me feel rushed. What stood out most was Dean's commitment to doing the job right. His workmanship was exceptional, the work area was left spotless, and the entire experience was seamless from start to finish. It's refreshing to find a company that combines technical expertise with genuine customer care. I highly recommend Detroit City Sweep to anyone looking for a trustworthy, knowledgeable, and professional chimney service company. ~ David-Anthony Powell, 20494 Santa Barbara, Detroit

HVAC completely DESTROYED, twice, by FSM, needing significant repair and rebuild. NO HEAT for over a MONTH in winter, did not even respond to my messages. URGENT CARE: Their poor work landed me in urgent care due to mold vented into the home. DAMAGED SIDING and INSULATION: FSM cut a hole in my siding, leaving the insulation exposed for months (not resolved); DAMAGED FLOORING: FSM staff cut a large unnecessary hole in my floor (not resolved); FSM staff helped himself to what he wanted out of my yard, then entered my garage without permission, despite being banned from the property himself. POLICE and Ordinance had to be called. NOT SAFE to hire them. POOR quality: Seams not taped. Cuts in the liner. Grading NOT completed, leaving the entire project needing to be redone (not resolved); You end up doing the work: I had to dig my own crawl with their staff for 4 hours! REPEATED SAFETY RISK: FSM staff became aggressive on site and demanded more money from me. Spray foam, dirt, tools, and trash left behind on the liner. DUMP PILE left on the property. POOR COMMUNICATION: FSM either does not respond, or it takes weeks of nagging them. Even in severe instances of personal harm, they will leave you hanging. There is no difference in email, salesman, supervisor, foreman, text, calls, office- they are all the same and do NOT communicate with you or one another. BUYER BEWARE! DON'T do it! You pay a fortune to have this company destroy your property and cause you serious harm.
