"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

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.

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.

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.

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.
