"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

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.

Most cottages are around 1,000 square feet, making them smaller than most other styles. However, cottages are defined more by their decor and architectural focus on simplicity, functionality, and a connection to nature than they are by a rigid square footage or floor plan. While cottages are defined more by their charm and appearance than size, the smaller footprint does help maximize the comfort and charm, and it keeps the focus on connection to nature and family.

While some highly experienced homeowners can frame a house independently, it is not advisable. You will need ample carpentry experience, a team of helpers, and professionals to sign off on your work to meet local building codes. For the safest outcome, we recommend buying or building a house with the guidance of professionals.

The average cost to build a modular home is around $270,000, and most modular homes total between $180,000 and $360,000. Of course, this price varies significantly by location, and the price tends to follow the cost of living in the area. There are quite a few other factors at play that can affect your pricing, including the following:

  • Number of bedrooms and bathrooms

  • Site preparation, including land clearing and leveling

  • Type of foundation

  • Utility connections

  • Cost of building permits

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.
