"We had just bought our house when we worked with Chuck and his sub-contractors. they were very professional and customer friendly. He asked plenty of questions to understand what it was we wanted and then confirmed before starting and would call to update us on how everything was going. The end results were exactly what we asked for!! If you want it done right, go to these guys!!"

"The remodel went great. Joe and his crew were friendly and prompt. They did the work in a timely fashion and were very good at communicating about the project. They did an amazing job transforming our bathroom. They replaced a vanity, walls, put in a tub and tiled. They also laid vinyl flooring and installed lights. We were impressed and thrilled with how quickly they worked and with the finished project. We would hire them again for another renovation. Please check them out."

"Sometimes it is hard to schedule with John, but when he gets there, the work is fabulous.  There are people who drive by my house and stop just to tell me how beautiful my front porch is.  They do a great job of cleaning up after themselves, as well. I would definitely hire JMJ for any kind of deck/porch or full remodel.

"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!!!

Home Building FAQs, answered by experts

Yes, professionals offer mantel and surround customization for aesthetic appeal.

Check reviews, compare quotes, and verify licensing. Ensure the builder has experience with modular construction.

Remodeling a house is often less expensive than building a new house. You can expect to pay an average of $100 per square foot when you are remodeling. The cost to build a house averages about $150 per square foot. When remodeling, though, some rooms cost more than $100 per square foot and some cost less. Use a home renovation cost estimator to accurately estimate your remodeling costs.

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.

An A-frame home can be cheaper to build than a traditional house, but that is not always a given. Prices can be fairly similar in some cases, depending on the location, design, and necessary site preparation. Costs for an A-frame typically run between $100 to $200 per square foot, which is comparable to the cost of a traditional home. The cost of an A-frame can come in under those numbers if you opt for a prefabricated kit.
