"KN Remodeling redid my floors, removed a wall and got my JADU permitted, plus many more random fixes. Whatever project I threw at Nathan and his team he got done. They were great and I would use them again."

"They are very professional and their work is stunning. They bring your vision to life. Jose and his crew remodeled our whole downstairs our 3 bathrooms and kitchen. You need to see the transformation on his IG page! Unrecognizable! Even with the delays in material during COVID they stayed on top of it.

"Richard and his team were great to work with. The Team showed up everyday on time and even stayed later to avoid unnecessary delays. Richard made sure I got the kitchen I wanted, not what the trend is and encouraged to be differentâ ¦ I loved that! He made the whole project very easy for me. He took care of ALL the research, ordering, and delivery of all appliances, sink, and faucets, and all within my budget. His value added services that are included in his prices are â 5 Starâ . I truly appreciated the way he and his team handled things that I brought to their attention to be fixed or reworkedâ ¦ Richard wanted to ensure things were correct and looked good. Another very positive experience was working with the shop he partners with to supply the cabinets, countertops, and tiles. Maxine made the experience extremely painless. I wanted color and her recommendations were exact what I wanted! I LOVE THESE COLORS!! And the countertop is absolutely gorgeous! Thank you, Maxine!!! Now, regarding the quality, I gave a rating of 4 stars. The construction and assembly of the cabinetry, I would give 5 stars. The only constructive feedback I have is related to the little details. I feel the overall clean up after the project was done could have had more TLC. One suggestion is to have one full day focused on detailing and touch ups. The cleanup for this project was at the very end of a long day of super hard work, the guys were tired and the last thing anyone would want to do is cleanâ ¦ totally understandable. That said, I donâ t want this feedback to take overshadow the amazing job Richard and Team did! Thank you, 3-D Remodeling, for making my dream kitchen come to fruition â ¤ï¸ â ¤ï¸ â ¤ï¸ ."

Customers say: True professional

"We found McCormick home builders through Angie’s list. They were not one of our original contacts, but they contacted us and came out to give us a quote. Matteo was extremely helpful, informative, honest, and gave us reasonable realistic prices, and did not try to inflate the prices or pressure us in anyway. We felt very comfortable with him immediately. We felt like he was a member of the family that we could just talk to and ask questions he was very personable. He gave us his contact number in case we had other questions and he was always available when we needed him for any type of questions or concerns. Mateo‘s team did a beautiful job. They were fast. They were efficient. They cleaned up beautifully. They did a wonderful job. They were very considerate of our time our needs and our neighbors. They were an absolute pleasure to work with. I would highly recommend Matteo from McCormick home builders for any home building projects, and we will be calling him again in the future!"

"Dealing with contractors is never easy, and Ben is no pushover, but with very few exceptions, Ben and his crew do what they say they are going to do when they say they are going to do it, and they do it very well. What else can you really ask for from contractors. He's organized and a person of integrity. I liked that he sent a Google chart with supplies to purchase that we could work together that helped me figure out what kind of parts and tiles to purchase. Great experience and our bathrooms are amazing."

"I wanted to replace carpet with wood-look vinyl in living room, dining room, library and office in my house, but the floors were very uneven. One company said they would only recommend replacing with new carpet and a second company gave me a ridiculously high estimate for the work. Jacobs Construction quoted a fair price, which went up a bit when they pulled up the carpet and saw just how bad the floors were. The final cost was far below the other quote. The work was done in just two days, and the floors are beautiful!"

Subcontractors questions, answered by experts

Yes, new home construction will always require building permits, no matter where you live. In most cases, you’ll need a general construction permit, along with plumbing and electrical permits for the utility lines in your home. Depending on where you live, you’ll likely find that you also need permits for things like connection to a sewage system or installing exterior components, like decks, driveways, patios, and curb cutouts. Leave navigating the permits required for new home construction to a professional to ensure your home is built legally and safely.

Yes, modular homes offer a wide range of customization options for layout, finishes, and features.

It is technically possible to draw your own blueprints, but the process is extremely involved and really demands help from an expert. A professional architect has an understanding of design elements, interior design, the functionality of different rooms in a home, and how everything from furniture, outlets, and light switches should be laid out to serve you and your family best. Hiring an architect for blueprints can get expensive, but it’s the most responsible way to begin a new construction project. If you’re keen on DIYing, you could consider starting the process and then having a professional take over.

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

Costs depend on project complexity, materials, labor, permits, and required revisions.
