"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."

"Overall, it went well. The project took about 7 weeks. John, the contractor explained that he would provide me with an estimate of the material needed and I was to pay the supplier and he would arrange for the delivery of the material. In this case Home Depot priced the  material and I paid Home Depot and received a detailed receipt. This system worked just fine for me. Deliveries were on time. JMJ Builders staff was always on time (Most of the time they were parked before 8am and came to the door at 8am.) They were personable and very polite. An important point is that John would virtually every evening after work would inform me  of the progress, any problems and the plan for the next days. I did not have a detailed blueprint, but described what I wanted and he would communicate with me to ensure we were still on track. The job was completed by Nov 12 except for a few minor details which he returned to complete by Dec 1.I would not hesitate to refer John to potential customers. I certainly plan to call him next year I may need to do some additional work on the first floor. By the way not only was the staff prompt but they seemed to always be working. John was not at the project every day all day, but he did come by and spent time virtually every day.
His staff seemed to be very competent.

My wife and I have used World Painting several times over the last four years in two different houses.  The most recent project was a complete makeover of the outside of our home.  We consulted with the World Painting staff on the design (two tones) and the proper colors to use.  We are very happy with the outcomes; both the appearance and the quality of workmanship.

"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!!!

"They are WONDERFUL. From start to finish, Zach and his guys were wonderful. We signed the contract in late fall of 2017. They came out this week and were finished in a day in a half. We have a large roof with high peaks, several valleys, and two places it's very steep. They had a huge crew, each doing something different. They worked well together and worked efficiently. I'm not kidding when I say, our yard is cleaner now than when they started and the roof looks WONDERFUL. I cannot tell you how happy Brad and I are. The entire crew was very conscientious and they absolutely pay attention to detail. I was impressed that the foreman showed up before 7:00 am and introduced himself. The second foreman showed up a few minutes later and did the same. All the guys were friendly and professional and they absolutely knew what they were doing. We're doing our windows in 2020, and they will be the first company we will call to come out and take a look. The roof looks wonderful!!!! Thank you. We are so happy."

Home Building FAQs, answered by experts

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

The most significant expense when building a barndominium is constructing the metal shell, which includes the roof, doors, and windows. Additional exterior components impacting the overall cost include metal siding and the concrete foundation.

Yes, such as using eco-friendly materials and energy-efficient designs for long-term savings.

Yes, you can finance new construction, though the process often requires a different type of loan than one for an existing property. There are several financing options available:

  • Construction-to-Permanent Loan: This is a common option where a single loan covers the building costs and then converts into a traditional mortgage once construction is complete and you move in.

  • Construction Loan (Stand-Alone): This type of loan provides funding only for the duration of the construction project. Once the house is built, you will need to pay the loan in full, typically by securing a separate, standard mortgage.

  • Builder Financing: Some custom homebuilders offer their own financing options, which may only require a down payment to begin the building process.

  • Bridge Loan: This can be a useful short-term loan to fund your new construction while you are in the process of selling your old home.

  • Home Equity Options: If you are building a second home, you might be able to use a home equity line of credit (HELOC) or a cash-out refinance on your current property.

It's also important to be aware that some lenders may have restrictions on financing for DIY house builds, so be sure to verify that you can secure financing before starting your project.

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.
