"I interviewed six solar companies and got bids from three. Charlie of Landmark construction & energy crew stood out much more above the other companies that I spoke and met with. He is responsive, always returned my calls quickly and he does what he says he is going to do. Charlie came over to my house and met with me before installation, during the installation and after. In addition he worked with his crew at the beginning of installation to make sure everything was perfect with a tricky area of my roofline. Above all of what I wrote above, Charlie and the office staff are very organized people. Charlie was able to provide me with a lot of information about rebates, taxes etc… and Every bit of information I could want related to monitoring my system, working with Landmark construction & energy crew, maximizing the cost benefits, and getting my tax rebate, are all gathered and clearly labelled in a binder. Charlie knew how to explain everything about solar and I could see during our meetings how much patient he have. Charlie didn't have to push anything in order to sell his work to me because his product was the one I wanted, it made sense, and the price was better than others. I can't think of a contractor and I've worked with quite a few once in the past and for this project, I met with several ones as well and Landmark construction & energy crew is more reliable, efficient, and customer-oriented. Thank you, Charlie!"

"I was selling my townhouse and the roof came up during the home inspection. I called several companies and received comparable quotes from each, but decided to go with Ocean Seven Builders. I'm glad I did. Jimmy, who estimated the job for me, was knowledgeable and gave me an approximate time frame for completion (1-2 weeks). This was an important aspect since closing was scheduled to happen in 3 weeks. After I put down my 1/3 deposit, they ended up having am opening in the schedule and were able to replace the roof within a week's time. The work took less than a day and the crew worked well. They took pictures and provided me with the invoice & warranty documentation I needed for closing. Invoicing and everything else behind the scenes was handled via email with the office manager. He was also very pleasant to work with and provided great customer service when I need the additional documents/info for settlement. Overall, the quality of work and customer service was exceptional. If in the future, my new home needs some roofing work, I would happily use Ocean Seven Builders again."

"Team was fabulous to work with, hands down. My vision was to add more living space without adding square footage. Expert Home Builders made it happen. Walls were moved, doors rearranged, pocket door installed, custom shelving, new kitchen with extra seating, and new bathrooms came to life. I felt I was part of the Expert team. My vision and their high standards created my perfect place."

"The work done was very high quality at a reasonable price. Michae and his team are extremely knowledgeable, professional and efficient. They ensure the job is done well and they do not cut corners. I was thoroughly impressed and satisfied with the work done on my home. If you are looking for a team to do a job for you that you can trust, I would HIGHLY recommend Michae and his team. I will be hiring them again in the future if I need more work done, without a second thought. It’s hard to find a team that you can trust to do excellent work. I am beyond fortunate that I found Michae and his team!"

Custom Home Builders FAQs, 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.

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.

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.

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

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.
