"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!"

"My wife and I could not be happier with our master bedroom addition and new Walk in Closet. Jorge and the A-Right crew were the most responsive contractors I have ever worked with and in my opinion that made the entire process less stressful and much easier. I will definitely be referring A-Right builders to all friends and family who are interested in having any type of remodeling done and I am already in the process to utilize them to retile the rest of my home. Thank you Jorge & Andy"

"I called All Service out to replace cabinetry below and both sides of my kitchen sink, and to install a new kitchen floor due to a tube that suddenly burst below the kitchen sink. The technician was friendly, professional, outlined the estimate well, and made sure I was happy with the results as the job went along. His team did a great job and I would hire them again."

Subcontractors FAQs, answered by experts

Pros provide detailed quotes and efficient management, reducing overspending risks on materials and labor.

The process typically takes 2-6 weeks, depending on the project size and level of customization.

New constructions, renovations, and interior layouts benefit from expert drafting.

Balancing aesthetics with functionality amidst space planning is important. To do so, you could consider consulting both an interior designer and an architect to fulfill both these needs. Or you can tackle it on your own by prioritizing personal touches amidst space planning that add to the look but don't take away from the livability of the space.

When conducting space planning, building codes and regulations need to be considered. As long as you are taking them into account and discussing them with the architect, you should be able to do your space planning appropriately.
