"I Highly recommend ALTA Renovation Corp. Their performance and track record exceed all expectations. This is the second large scale job, Jose Diaz and Crew were hired by us. I have been in construction (masonry) for more than three decades, so I’m no stranger to Home Improvements and ALTA by far was the BEST Quality of work performed. They handle all aspects of your work needed. No need to hold up the job because a Plumber or Electrician can’t be there for a week. They do it all, QUALITY work and at Reasonable Price. Jose Diaz, Owner of ALTA is compassionate to your needs and is approachable and understanding. Of course, the job scope changes whiles the job is ongoing, but it never an issue with ALTA. Back to my opening sentence, I HIGHLY RECOMMEND, ALTA, Jose Diaz and Crew. PS The Crew has been with ALTA for some time and they are extremely respectful. They all loved my family, grand kids and dog. ALTA is an 11 on a scale of 1 - 10."

"Since we are looking in to buy in Ohio, Mark could not work with us due to not being licensed there.  He was very helpful and spent several minutes on the phone answering questions and helping me understand a couple different unconventional loans.

Subcontractors FAQs, answered by experts

No, it’s not legal for unlicensed individuals to conduct structural calculations for buildings or building repairs. Not only do licensing requirements prevent DIYers from tackling this project, but mistakes can also be extremely dangerous and put your property and anyone inside or near it at risk of severe injury or even death. You should always hire a licensed and certified local structural engineer to make structural calculations.

Designing a building takes 2-6 months, depending on project size, required permits, and revisions.

Costs vary depending on project complexity and scope. Architects generally charge a percentage of the total budget or an hourly rate for their services.

Villa exterior features often include large windows, arched doorways, patios, terraces, greenery, and gardens. Common exterior colors for villas are whites and off-whites, soft browns, and clay tones. 

Custom homes can take an average of 18 months to build, mainly due to the lengthy design process, and most projects take somewhere between 12 and 24 months. When you work with the right custom home builders near you, they can help you map the road ahead and understand what can speed up or delay the timeline. Choosing locally available materials, for example, can speed things up without losing that customized touch.
