Customers say: True professional

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Deleon E Hijo did a major renovation on our condo includign new fireplace, relocated door, crown molding, two full bathroom remodels, new flooring, baseboards, and paint. From start to finish, they were accommodating, easy to communicate with, and kept us on schedule despite the scope of the work. They handled the complexities of a condo reno (building rules, tight logistics, changing permits) without a hitch. Their craftsmanship is excellent - clean trim work, beautifully redone bathrooms, and finishes that look like they were always part of the space. Highly recommend if you want quality work done right and on time."

"Maximo Construction gave us a great bid, has competent and friendly workers, kept to the agreed upon schedule, and turned out exceptional products in our new composite deck and pergola. Maximo engineered the pergola to hold retractable canopy panels. The pergola is extremely sturdy, symmetrical, and aesthetic. His communication was excellent throughout the entire project. I could not recommend him and his company highly enough. I will definitely hire him/them again!"

"I had to have my entire bathroom torn out and replaced with new walls, new enclosure, tub and flooring. I am very happy with the job that Cobar Builders did in my home. They were all very friendly and updated me on their progress and asked me how I liked certain things done...honestly this is the first time I have ever hired a contractor to do work in my home and at first I was very nervous, but all my fears and worries have been allayed by Elvin, the owner, and his crew. Elvin and his team were always up front with me about any additional costs and was very responsive to my calls and texts. I definitely recommend them highly."

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.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.

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

Whether it’s more affordable to gut a house than build a new one depends on the markets where you'd be buying and selling. However, it’s usually less expensive to renovate a home than to build new construction. 

Most homeowners pay between $100,000 and $200,000 for demolition and remodeling costs, whereas the average cost to build a new home is between $139,000 and $531,300.

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel
