"Hired Superb LLC to remove three thru the wall air conditioners, brick up opening on exterior and drywall interior opening. The interior drywall installation was very good. The brick installation on exterior wall was amateurish at best."

"Very Happy with choosing Golden Temple Builders for my construction needs. Nick the owner was very professional and clearly explained the stages of the project and was able to work with the pricing points that I could commit to. His team went above and beyond my expectations, and job was completed even well before promised. Would Highly Recommend!!!! 10/10"

"I don’t usually leave reviews but I had to write one for Rightway Construction. Great prices and even better customer service. They did our master bathroom and completely remodel our floors. We couldn’t be happier. I will re-hire them in a heart beat."

"J & H was phenomenal. Great price and an exceptional product. Replaced all kitchen countertops and installed new countertops on the bar. Could not be happier with the finished product. Answered all our questions and worked with us on customizing some items. Countertops and backsplashes all match patterns at the joints. Looks like one continuous piece. Highly recommend J & H."

Custom Home Builders FAQs, answered by experts

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

To get a quote from a builder or general contractor, contact them over the phone or online and explain your project. If you already have house plans drawn up, they’ll need to review them to determine the project's scope before providing you with a quote. Ask for your quote in writing and compare quotes from several pros before choosing the best one for your needs.

Shipping container homes last at least 25 years on average, but they can last even longer with proper maintenance. Since shipping containers are made from metal, they’re quite vulnerable to rust and corrosion. This issue is exacerbated in coastal areas or areas with a lot of precipitation. To extend the life span of your container home, install siding that protects the exterior. 

Renovating or remodeling an existing structure is usually less expensive than the cost to build a new house. That’s because you can save on the costs of new building materials, laying a foundation, framing the entire building, and installing new materials and utilities throughout the house. However, if a home is in very poor condition or is incredibly old, you could spend more on upgrades and restoration compared to building from scratch.

A-frame homes are on the smaller side. While there’s no set square footage amount it has to be, it will usually come in around 1,000 square feet or smaller.
