"Sentri Homes provided the most professional flooring service I’ve ever had. The LVP installation turned out absolutely beautiful, and I was amazed at how quickly everything was completed without sacrificing quality. The crew was fast, accurate, and extremely detail-oriented from start to finish. Everything was installed cleanly, precisely, and with real craftsmanship. The entire process was smooth, efficient, and far beyond what I expected. I would absolutely recommend Sentri Homes to anyone needing flooring installed."

"It went very well! Chuck was an absolute gem, was thorough, kind, and did an amazing job with the work he does. He doesn't leave any detail untouched and is willing to go above and beyond for the customer! Our tub ended up leaking and he came back, fixed the issue above what we asked, replaced the ceiling tile in the floor below where water had damaged it free of cost(even though it wasn't his fault it leaked), and always made sure we liked the final outcome on whatever he had built that day. I felt a man who truly CARES about his job and work place which is hard to come by now days! Definitely would hire again! ?"

Custom Home Builders questions, answered by experts

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.

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

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.

A green home is one that focuses on conservation, with the goal often being net-zero carbon emissions and self-sustainability. It will often include some kind of self-generation equipment, like solar panels or a small wind turbine, high-efficiency electrical components and mechanicals, and high-quality insulation and air sealing to reduce the loss of conditioned air. Many green homes also include xeriscaping or rainwater collection to cut down on drainage and water consumption.

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.
