"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"I'm very happy with the work that was done by Landmark construction and energy crew. At first, we met with Ron that came over and met with us about the issues that we had with our water heater and with the bills that we currently pay for electric. Ron recommended us to replace the bulky old water heater and to install a tankless system that will supply hot water immediately and with the use of less gas. We liked that idea and we decided to go for this project. Ron came over to our house with his 2 people that basically took care of all the removal and the installation of the new system. The work that they did took only 2 days from start to finish and now we have more space at the garage, and the bills are much lower than before…."

"After having a disastrous master bathroom remodel where the subcontractor had botched the job, I was faced with finding a company that can fix it. The job was done so poorly that it had to be redone. Naturally I was quite skeptical after this ordeal.. When I contacted Expert Home Builders, Owner came out and assured me that they could complete my master bath to my standards (I am very picky) and it would be done in a very timely manner. Their tile man and painter did exquisite work. After the glass shower, vanity, and tub were installed, I was extremely happy with the results. And you will too if you choose to use them. They offer first rate quality on their remodeling services. I recommendation them without any hesitation."

"We had a big kitchen remodel with layout changes, so we were a bit nervous at first. Ron made the process a lot easier than expected. He coordinated everything and made sure each step was done properly before moving on. The workmanship is solid, and the finishes look high-end. We?re really happy we chose Ocean Seven Builders!"

"His name is Andrew Johnson. He is going to be doing our carport next. He does all of our electrical but he also does incredible solar. It was around $17,000 for the solar. We have a big house. You can't beat his prices. He doesn't have a huge company. His guys are great. He shows up when he says. He does meticulous work. The city's came out and told him right in front us that he did better than perfect. He lives in our neighborhood. He told him to get on Angie's List"

Subcontractors FAQs, answered by experts

Professionals optimize layouts, improve energy efficiency, and ensure structural safety and compliance.

If your project is complex, it may make sense to hire an architect to draw plans. An architect might also be a good person to hire if you want to ensure your plans adhere to building codes and regulations.

Italianate architecture is a reinterpretation of Renaissance styles, combining elements of Italian farmhouses and villas with Victorian materials and construction. This home style emerged in the Victorian era, gaining popularity in the U.S. in the mid-to late-1800s. The style came about in response to what many then viewed as the too-rigid and stuffy Classical style designs. 

Hiring a professional to do a loft conversion will certainly speed up the process. The construction steps required to change the slope of the roof can be quite difficult to do as a DIY job. Should the project run into any snags, like rot in the joists, frayed wiring, or roof leaks, hiring a local home remodeling professional makes it far easier to handle these issues safely.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.
