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!

Best cement company to do any cement work needed. Very prompt service, competitive pricing, and…read morewhat a team work project this company finished for us. Communication was top notch. This company repaired cement slabs on our homes sidewalk and common area of our subdivision. If you want quality work done I'd look no further. They were fantastic! Thank you again for doing a wonderful repair job on our home's sidewalk and common area sidewalk. ​You guys are the best!

Joe and his team were amazing. They came to our house and ripped out 2 patios and a front walkway…read morethat looked very loved after 20 years and needed to be updated. The goal with getting the stamped concrete done was to eliminate the weeds and moss that continually grew in between the cracks and to eliminate the dirt that was constantly being tracked in. We chose a simple stamped concrete pattern that looks amazing and fulfilled all my goals. The grill even got a new home in the process. We also had the garage dug out and replaced with new cement and a 4 foot apron installed. My husband loves the new concrete in the garage and is looking forward to the snowy wet muddy season when everything will drain out of the garage and not puddle up on the floor. Joe and his crew were great. They cleaned up everyday after they finished, were polite and very hard workers. We would highly recommend Divine Decorative Concrete to anyone who needs concrete work done.

The entire team at Detroit city sweep Is awesome. From…read moreupdating, maintaining and servicing 3 fireplaces in a historic home to helping us vent our kitchen stove in our hearth the entire team from quoting to scheduling to actual work has been wonderful to work with. The first thing I noticed right away is they actually answer their phone when they call so that was already a plus for me. I was able to schedule an estimate quickly and get someone out to help us address our main issue which was our kitchen not venting correctly, in addition to a fireplace that we would soon need because of the cold Detroit winter. As a new homeowner, we did want to make sure that the fireplaces were in good working condition before we actually started using them so we requested a estimate on what the service and maintenance could potentially be for the fireplaces that we had in our house and any recommendations that they would have. The process was very straightforward. They easily walked us through the quote and what was needed and why, in addition to what the current condition of the fireplace was in to what would need to be done and how it would fix the problem as well as what comes after the service what could be expected what they would be able to help us with should we come across any hiccups after the fireplace maintenance and what warranties came with the products that we purchased. We purchased dampers some gas fire logs, and had our fireplaces updated so that we could use them last winter. From there coming this winter, we assumed that we would have to have the fireplaces serviced again because it was a new year, though we only had a handful of fires in the living room fireplace they scheduled the appointment. They were prompt and scheduling, as well as coming out for service and transparent enough to say we haven't used our fireplace enough to fully warrant a cleaning. This was refreshing to see this type of honesty from a contractor. Then we ended up having an issue with the smoke coming into our house on our serviced fireplace. They were able to address solve an analyze, the reasons why the smoke was coming in to our living room, though everything looked up-to-date and ready to go. It was next level problem-solving skills that they would rarely run across because of the unique fireplace that we had in our Historic house. It was very appreciated that they did not just give up and ask us to spend a gazillion dollars to throw money at a problem. I highly recommend Detroit City sweep for the professionalism the availability, and of course, the quality of the work.

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.
