"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."

"We were extremely happy with the work performed by H&M. Moises, Hector and crew were courteous and did whatever needed to please us. They did most of the renovation in our condo......painting, installation of bathroom cabinets, sink, installed tile floor, etc. They also installed vinyl flooring in our kitchen, living and dining rooms. They had a plumber replace our heating baseboard, I would highly recommend H&M if you want excellent work done!!"

Subcontractors FAQs, answered by experts

A designer is a great choice for remodeling projects that don’t require significant structural work. For remodeling that includes structural work like removing load-bearing walls, altering exterior walls, or adding on a room, an architect can design and execute the renovations while ensuring your home remains structurally sound.

Costs depend on desk size, labor, included features like drawers or motorized height adjustments, and required wall anchoring.

Most Greek Revival architecture homes are one and a half to two stories, depending on the footprint, which sets them apart from some Federal architecture homes that are three stories. The gabled roof on the second floor can sometimes cut into the living space, especially on smaller homes of this style, which leaves a much smaller living area upstairs.

By providing precise guidelines that reduce errors and facilitate smooth execution.

Universal design costs can be minimal when you add them during construction; however, adding universal design principles to existing homes can sometimes increase renovation costs. For example, a mid-grade bathroom remodel is estimated to cost around $30,000, while a standard universal design remodel can cost closer to $40,000. Adding accessible design components can include widening hallways ($500 to $2,000), curbless showers ($2,000 to $8,000), and widening doors ($400 to $800). Keep in mind that these increased costs can lead to higher resale values because universal homes may appeal to a wider variety of buyers.
