"Al and his assistant installed two window air conditioning units in windows that another installer said could not be done. The other installer from TaskR installed one of the units in a non-preferred window and left quite a mess, including crooked drill holes in my wooded sills. (My place is 105 years old, but my window sills have metal frames and modern windows.) Al and his assistant’s work was perfection! I was so pleased, I have already referred Al to 2 neighbors. Al is great at communication, very pleasant to work with, and honest. They cleaned up everything and offered to take the boxes and packing materials out to my bins. This was a relatively small job, but worth the money. Al charges a 2-hour minimum, which is more than fair. I will hire Al again and continuing recommending him and his team."

"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."

"I'm very happy with the services offered by Platinum Home Builders. From booking an appointment until renovation work was completed, we were provided with relevant information. Their designer John was so patient to note all the detailing we looked for. We will again appoint them for future works."

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!"

"Delighted with the final product- well done upgrades in our master bath. Especially pleased with the quality of the tile work. Generally responsive, occasionally we did find that we needed to call or text to see if /when subcontractors we’re coming, or else a day or more would go by without progress."

"My husband and I just finished a remodel of our guest house in Sherwood Forest. We used a company called Universal Home Design Inc. The contractor and owner of the company Ouriel Lousky was most professional in every aspect of the job. His crews were timely and most efficient in every way. He had his subcontractors lined up so the job was never lagging behind. I would recommend him to anyone who is planning on a remodel or a renovation. Mary V."

Subcontractors FAQs, answered by experts

The country's most famous Neoclassical architecture appears in major government buildings and college campuses. The White House is unmistakably the most famous example, though the Capitol Building and Thomas Jefferson's Monticello are also iconic uses of the design.

A split-level home is one that has several staggered floors connected by short staircases, while a split floor plan separates the primary bedroom from the rest of the bedrooms. Split floor plans are most often found in single-story homes, while split-level homes are always at least two stories.

You have three options in terms of professionals who can draw up blueprints: a draftsperson, an architect, or a structural engineer. A draftsperson can sometimes draw up plans for new construction, but they more often work from approved plans for alterations or to provide 3D drawings. Architects are usually the best option for standard residential construction projects. Structural engineers might be necessary for custom home builds or for alterations that could affect your home’s structural integrity. Draftsmen cost the least of the three, followed by architects and then structural engineers.

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.

Above all, the downside to building a new house is a longer timeline. You need several months to finish the build, depending on the supply chain and labor availability in the meantime. Building a home compared to buying one is also more expensive, both in the building process and when it comes to mortgage rates and property taxes.
