"Terrible work, terrible service, sad experience. Co totally botched flooring installation during kitchen reno through carelessness and obvious mistakes. Lone worker (Charlie Sr) slopped poly coating on cork flooring w/o vacuuming and then left the house before it dried. The seams puckered and debris and hair dried into the finish. The next day, other unsupervised workers tried to sand the tiles as a "fix." This ruined the cork. The end result was so obviously substandard that Premier paid for the tiles needed to fix (the original flooring material cost over $3,000). Now stopped on everything for 3 weeks while waiting for new tiles. Attitude remains unprofessional. Excuse after excuse about why Charles is unavailable to work after tiles are delivered. A constant problem throughout the project - family obligations, "Easter Monday," "I'm in Miami, "I'm in Phoenix" - never the truth of working for others. Save yourself. I'm out weeks and thousands."

"Carlos was extremely attentive to what I needed for my closets and provided great recommendations as we were brainstorming different solutions for how to customize for my new condo. He was prompt in all of our correspondences and transparent about the entire process. I have a couple of oddly designed closet doors that we had to work around; but when the drawers I was hoping for weren't available, Carlos said that he would custom build to what I wanted! We hit a speedbump with me catching covid, but Carlos was very supportive and still came through to complete 2 out of the 3 closets I contracted him for while I stayed at the far opposite end of the condo. I was so grateful for the enthusiasm, professionalism, and straight up care Carlos and his partner put into this project. And I am LOVING the work that's been done so far! Can't wait to get better so that we could start back up on the master bedroom closet!"

Major renovation multiple room services FAQs

Detached structures generally require more investment than interior conversions due to additional foundation work, independent utility connections, and exterior construction requirements. These standalone offices typically align with addition costs, ranging from $80 to $300 per square foot depending on design complexity and finish quality. Consider additional expenses for separate heating/cooling systems, insulation requirements, and potential zoning restrictions when planning a detached workspace.

Most jurisdictions require permits for structural modifications, electrical work, plumbing installations, and HVAC alterations. Requirements vary significantly between municipalities, making consultation with local building authorities essential before beginning work. Proceeding without proper permits can result in financial penalties, construction delays, or requirements to remove non-compliant installations, potentially increasing your overall project cost substantially.

Converting existing space is typically more economical, with costs ranging from $50 to $200 per square foot compared to $80 to $300 per square foot for new additions. Room conversions avoid expenses associated with foundations, exterior walls, roofing, and additional utility connections. Your decision should consider not only immediate costs but also how repurposing existing space might affect your home's overall functionality and value proposition.

Room conversions typically require between two and six weeks, depending on the extent of modifications. Building an addition generally takes three to four months from initial planning through final inspection. Your project timeline depends on permit processing, contractor availability, material delivery schedules, and any unforeseen complications discovered during construction. Weather conditions and seasonal factors may also influence completion timelines, particularly for exterior construction phases.

Home office expenses related to business activities may qualify for tax deductions, though specific eligibility requirements apply. You'll need to maintain thorough documentation of expenses and use the space exclusively for business purposes to qualify for most deductions. Tax benefits vary based on employment status, space utilization, and current tax regulations. Consulting a qualified tax professional before making renovation decisions can help you understand potential financial advantages specific to your situation.
