"I contacted World Painting after CertaPro dropped out of sight.  We quickly got an appointment with them and they were ready to give us a bid that day.  The price was reasonable and it included power washing, caulking, and painting our porch floor along with the entire house.
They were able to start within the week and kept us updated through out the project, letting us know what was the next step and when it would be completed.  Customer service was excellent.  When I had a question they called me back within the hour. 
They did an amazing job and we have gotten tons of compliments on it.  We would definitely use them again.

"We hired SAL to install new ceramic tile floors in our hall bath, master bath, & master hallway. They also put in new 3/4 cherry hardwood floors in my master bedroom. The craftsmanship was immaculate. He shows up on time, worked on my job everyday till it was done, cleaned up at the end of the day, & most importantly was very respectful to me & my family. I am so pleased with the work that I would recommend SAL to everyone!!!! Great work, great price, great guy!!!

Custom Home Builders FAQs, answered by experts

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

A green home is one that focuses on conservation, with the goal often being net-zero carbon emissions and self-sustainability. It will often include some kind of self-generation equipment, like solar panels or a small wind turbine, high-efficiency electrical components and mechanicals, and high-quality insulation and air sealing to reduce the loss of conditioned air. Many green homes also include xeriscaping or rainwater collection to cut down on drainage and water consumption.

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

The longest part of building a custom home is the design phase. It takes multiple professionals and a ton of work to bring your vision for your dream home to life while sticking to a homebuilding budget and also ensuring everything is built to code. Expect the design phase for a custom home build to take six months to a year.
