"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."

"Great company! Very professional. When my basement flooded they came in and made this stress free for me and handled everything in a timely matter. My basement looks great now and I couldn't be happier. I highly recommend."

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 Construction to build us a garage in Morton.
All I can say is WOW!!! Nice, polite, honest, clean, punctual?My husband found
them on Google and after visiting their website we decided to give them a call.
They did everything they said and did a beautiful job right on budget! I recommended
them to my sister who needed a tile floor installed in her kitchen. Scott did
an amazing job on the tile as well. My sister was so pleased?Her & I both
would recommend SAL to everyone. Job well done!

Custom Home Builders FAQs, answered by experts

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.

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.

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.
