"I’ve met Carlos while he was doing a remodel at my customer’s house. Since then we have added LeBirch Development to our team. He has been able to prove over and over again that no job is to big. He has finished to completion every job on a timely matter that we can keep up with him and his crew. He is puntual and on top of his game. He knows everything that’s is going in his jobs and will harass you to get what he needs to not fall behind. I’ve been in this business for over 17 years and met many contractors I truly can tell you that if you want a job done, professional, timely and from the what I hear affordable you can trust Lebirch Development and Construction ask for Carlos Neira. You won’t regret it !!!"

"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."

"We are very happy with our new countertops. They look great. Jamie and his team did an excellent job from beginning to end. And even stayed late to finish it up due to us leaving for vacation. The customer service was top notch and I would highly recommend them. Thank you Jamie and crew."

Custom Home Builders questions, 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

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.

Construction typically takes 3-6 months, including site preparation and assembly.

The average cost to renovate or remodel a home is $52,300, with most projects ranging from $19,500 to over $88,400. However, costs can vary significantly, from as low as $3,000 for a small project to $170,000 or more for a complete home remodel.

Several factors influence the total price, including:

  • Project Scope and Size: The extent of the renovations, whether it's a single room or the entire house.

  • Location: Geographic location affects labor and material costs.

  • Materials: The quality of materials chosen.

  • Room Type: Kitchen remodels ($14,500 - $70,000+) are generally more expensive than bedroom remodels ($1,500 - $5,500).

  • Other Factors: The time of year, complexity of the work, and any additions or expansions.

On a per-square-foot basis, you can expect to pay between $15 and $60 for standard projects and up to $150 for luxury renovations.

Examples of specific project costs include:

  • Basement remodel: ~$20,200

  • Garage remodel: ~$27,900

  • Loft conversion: ~$20,200

  • Disability accommodation remodel: ~$4,300

  • Major home repairs: ~$11,700

If you are financing the project, note that some loan programs, like the FHA 203(k), may require a minimum project cost (e.g., $5,000) and will necessitate a home appraisal and professional cost estimates. Using a home renovation cost estimator can also help you budget for your project.

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.
