This response is simply to tell you that you should have checked your books before you replied to my post. you WERE paid. My check for $760 was sent on 12/13/25. Your company sent me an invoice showing a balance of $0 on 12/18/25 and your company cashed my check on 12/22/25. Once again, you respond without really checking on what has occurred. This seems to be a habit of yours in my opinion.

Originally, as you can see by our review below) we were very happy with the installation of our…read moreJames Hardie board. Unfortunately we found out the hard way that Grennan Construction does not stand behind their work. During the installation they made a human error and did not caulk and apply flashing correctly which led to a leak to our dining and living room ceilings causing over $2,000 worth of damage. We have made close to 20 texts or phone calls to Fred, his employees or his office in an attempt to have them come out access, and effectively stop the leak. They told us it was fixed once, we had the inside of our home professionally repaired and painted only to have the leak return shortly afterwards. Go Elsewhere!! Was referred to Grennan Construction by a trusted source and they didn't disappoint. The crew was very polite and conscientious from beginning to end. The Hardie board installation looked good from day one and continues to look great. You should definitely use Grennan Construction if you the job well done at a fair price and on schedule.

We just wrapped up a kitchen and bathroom renovation with Detroit Build a few weeks ago and it…read morecouldn't have been a better experience! This is a long review, but I tried to include what would have been helpful when I was looking for the right contractor to work with before our project started. I reached out to the team late last summer and scheduled a time for an initial consultation in September 2020. Several members of the team came out, including Seabrook, the owner, and Rebekah, a designer with Whiski Kitchen. One thing I loved about that initial experience is that we discussed absolutely everything up front - the design concept, how far we should go with the scope of the project, the timeline (we entered into this project when I was 4 months pregnant - whoops), budget, etc. Then, Rebekah took everything I was looking for and turned it into a beautiful digital rendering that we tweaked a bit from there (for the record it looks EXACTLY like how our actual kitchen turned out!). I was really blown away by how much time and care they put into the project before we had even signed a contract or committed to anything. This process between the initial meeting and signing the contract took a couple of months but it was well worth it in the end and the back and forth up front saved us so much time once the project was underway. Work started a couple weeks later! During our early conversations Seabrook jokingly told us that no matter who we work with for this reno, we were going to be miserable while the house was torn apart, but it seriously wasn't that bad! I give so much credit to Detroit Build for how smooth the process was for many reasons, but most notably: - The team is pretty exceptional at project management and did an excellent job of ensuring there were almost no unused days while the project was underway. We chose to leave the house every day while the team was here (except Saturdays) and of the 12 weeks they were working, there were maybe only 4-5 days when I came home and couldn't clearly tell what had been done that day. They also wait to start demo until materials (such as cabinets) start to come in so you don't spend any time waiting on deliveries, which felt really important given that EVERYTHING is backordered at the moment. - Kristy was my main point of contact during the renovation and she's the absolute best - I miss texting with her every day now that our project is over! I didn't have a day-by-day project schedule or plan to go off of which I actually really liked because this business can be incredibly unpredictable and it's easy to feel disappointed when things don't get done on the exact day you're expecting them to. Instead, I had near-daily updates from Kristy via text - especially after the rough inspection was done, and a general idea of when we'd see major milestones completed and I always felt like I was in the loop/knew what to expect. - They were transparent about how the timeline and cost would be impacted if I made changes to the plan while the project was underway so we could weigh all aspects into our decisions. That said, we added quite a few elements (including painting two additional rooms outside of the initial scope) and the project ended right on time! - I just love the Detroit Build team and everyone they work with, both direct employees and subcontractors. Everyone was so kind, respectful and treated our 100-year old home like it was their own. The team even made recommendations for the design based on things they knew we'd need when we had a baby that I would never have thought of! They really treated our project with care and made us feel like a priority. At the end of the day, no renovation is going to be 100% perfect. I work in project management personally and I make mistakes, so it would be unreasonable for me to expect that anyone I hire wouldn't occasionally do the same. What set this crew apart was how they handled it when there was a concern or a miscommunication (though there were so few). In fact, the team proactively pointed out issues to us (like a small scratch on our tub) that they believed to be their fault that I hadn't even noticed. At the end of the day those experiences just showed me how much Seabrook and his team care about taking care of clients. We couldn't have asked for a better team to work with during this renovation - I hope this has been helpful if you're considering DB for an upcoming project! We'll definitely hire them again in the future.

Let's start with the positives: The owner of Detroit Build came out and looked at the job and was…read morevery helpful. The workers who came into our house were very kind and friendly. They covered all of our floors leading up to the bathroom (remodel). The completed job matches our original plan. They were able to make adjustments when things were not going according to plan. They were able to obtain all the materials we picked out. Anytime we reached out to our Project Manager he was able to respond and give us information in a timely manner. Since we don't have a garage, they were able to provide us with a trailer which held all of our materials on site. Negatives: They gutted the bathroom as planned. When they laid the floor, they never covered it with paper so they continued to remodel the bathroom walking on the newly installed floor. Seems like not a big issue, but it's winter and they were dragging in dust, snow, ice and salt onto our new black floor. All of the debris was falling onto the new floor. Due to the fact that multiple people are working on multiple jobs, mistakes were made and workers had to come back out to fix errors made. Part of why we went with Detroit Build is because they had a design team. We were still required to go out and find the materials on our own. Our assumption was they would take care of this step. While our Project Manager did get back to us, we had to reach out weekly to get updates. At the end of the project the only cleaning that was done was construction cleanup. We were disappointed to find out that they did not have a cleaning company to take care of this job. It wasn't a clean and pristine feeling that you would expect with a remodel. We had to call and get a "deep clean" on our newly remodeled bathroom.

Started project in 2021, Brad from Peaks met with us, discussed scope of project, and we signed…read morecontract. Peaks started project but when we were concerned with workmanship Peaks stopped work. Called office numerous times and were told need to talk to Brad and get back to us. Over 3 years later and 1500 phone calls to Peaks trying to get answers on when they were going to complete project or refund our money and we would find a new contractor. Peaks never returned calls - always told had to talk to Brad and would get back to you. Put down $20K to start work - only work completed was drywall and trim in one 17 x 1 ft room. Drywall was wavy. Trim person had to fir out drywall in spots to get trim to lay flush - shoddy workmanship. Paid $19K to have all granite replaced in kitchen. Never replaced and would not refund money. Brad agreed to store our stone at his warehouse to keep it out of the way of trades until framing completed and stone could be installed. After numerous attempts to get stone from Brad, finally agreed to give it only if we would sign a fake letter that we owed $9K in storage fees and would not help load over 1000 sq ft in pallets with fork lift, made trades load by hand onto trucks. For any person looking for Peaks to do work - BE FOREWARNED! Brad and his company Peaks are not trustworthy, do not stick to schedule as promised, and ignore clients. He stole our money and refuses to refund. We are currently in litigation with Peaks to return money owed to us. We asked them if we could just get our monies back and move on but Brad stole our money and refuses to answer us. HE IS A SNEAKY LIAR! DO NOT TRUST THEM! I'm sure Brad/Peaks will respond to this with please call our office to reach a settlement but that is a total LIE! He may seem nice and honest but he is NOT! I'm trying to warn any person(s) to not do business with Peaks! We do not anyone to have to go through our nightmare with this SHYSTER! PLEASE BEWARE!
