"I highly recommend hiring Adrian Kovaci and his crew at Ceres Construction for your home construction project.The quality of their work was superb, the cost was comparible to the three other quotes I got from other companies, and their work presence at my home was unobtrusive as I could hope for. My two level 1923-built Richmond district home in San Francisco had a derelict passage to my garage - crumbling door, wobbly side stairs, and dry-rotted siding. Nothing was up to code. Adrian noted all the items that had to be reconstructed and said the project would take up to 20 days (it actually was finished in 18 days.) Adrian was very accommodating in giving extra finishing touches to my door hallway without extra charges, which I appreciated. I was concerned about the cost of the project and the disruption the work would cause, but Adrian's calm demeanor and the friendliness of the crew put my worries to rest. Thank you Adrian for leaving the work area spotless and for the quality work!"

"We decided to remodel our outdated bathroom, and McCormick Home Builders was a fantastic choice. Khaled and the team delivered high-quality work within the timeline and our budget. Every detail, from the tile work to the lighting, was beautifully done. They communicated well throughout, keeping us informed at every step, and the end result was truly a spa-like bathroom we can enjoy daily. We’d love to work with them again!"

"Our roof was in bad shape and we needed to have it replaced. I had gotten estimates and decided to go with Home Pro Remodeling. Emil and Brian were our contact people for the project. Emil was very professional and paid attention to our concerns. He worked with us through the entire project to our complete satisfaction. Brian is extremely courteous and helpful as well! The project went very smoothly, was completed before the initial project end date, and the results were beyond our expectations. The job turned our beautifully! Our new roof looks FANTASTIC! Our neighbors have commented to us how great it looks. We are very pleased with our experience with Home Pro Remodeling and would definitely recommend them."

Storm Shelters FAQs, answered by experts

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.

Local zoning laws and building codes will determine whether you can build a guest house in your backyard. These laws may limit the potential location of the guest house on your lot or the size and look of the structure. If your lot isn’t large enough, you may not be able to build a guest house at all. Speaking with a local home addition company can help you learn about the local regulations and your other options, such as adding an ADU onto the main house.

Yes, particularly handy DIYers can build their own storm shelter, especially when using a prefabricated kit and an existing space. However, it is a large project that can take several weeks, requiring significant manual labor and heavy equipment. For these reasons, hiring a professional is often recommended. You should always leave certain jobs to a pro, such as installing an underground shelter, projects requiring site excavation, or any custom-designed structures. These types of builds are complex, labor-intensive, and can cost more in the long run if not executed properly.

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

A 2,000-square-foot modular home costs an average of {AvgCost}, and most homeowners pay between {AvgRangeMinCost} and {AvgRangeMaxCost}, depending on the customization options you choose and the quality of materials. If you choose a more custom design and go all out with upgraded finishes, you could pay as much as $600,000.
