FREE estimates and 10% off for Angi's List members! A.G.A Construction, Inc. is a licensed, bonded and insured, full-service construction company. We offer services in both residential and commercial remodeling including, but not limited to, new construction, room additions, kitchen and bathroom remodeling. Our mission at A.G.A Construction is to provide excellent customer satisfaction and top-quality work. We work hard to maintain high standards of exceptional customer service and superiority that has become expected of us over the years. Whatever your remodeling needs are, we take the necessary time to discuss with you the wide variety of options, products, styles, specification and your desired budget available in order to make your vision a reality. When working with our team you can be sure that your remodeling project will exceed your expectations. With any remodeling job, a project is only as good as its foundation. The same is true for our company, which is built on a foundation of trust and strong relationships with our clients. As our saying goes “When we are done, you will be happy, and until you are happy, we are not done.”

"We started the process of building our detached ADU at the beginning of 2022. We hired an Architect, who drew up a plan to build a 1200 sq ft, 3 bedroom 2.5 bathroom house. After 14 months of waiting and addressing revisions required by the Los Angeles Department of Building and Safety we got our permit in “Ready to Issue” status. While waiting for city approval, we all started looking for a fair, reliable and honest contractor who would do good/solid construction. We started the process of interviewing contractors and getting bids for the job. After several meetings and several bids, we met Micky Kanian with “AGA Construction”. We found Micky on Yelp. One of his references took us thru an ADU that Micky and team built for his elderly mother-in-law to live in. This family could not say enough good things about Micky and team. They took us thru the property and explained their experience in great detail. We saw another beautiful AGA project, a 5k sq ft + project that was in progress and really knew that day that we’d found our contractor. We weren’t quite ready to pull the trigger for personal reasons, so we put the project on hold. Meanwhile, we continued to collect a couple of other bids that were already in progress. During this process, AGA kept in touch with us. They checked in every few weeks or so, without being pushy or intrusive. After a delay of about 9 months, we decided to move forward with AGA construction. No one is a tougher critic than me. I was dreading this project because of the amount of stress that I knew we’d be under. Both financially and mentally. We’ve all heard and/or lived thru the horror of a construction project gone wrong. I won’t bury the lead any further. We love our ADU!!!!! We started the project on Jan 31st of 2024. We were told that the project would take 6-8 months. We lost the first 6 weeks or so with the heavy rains from last year, but even with that delay, we were mostly done with the project by the middle of August. We ran into the “expected” unknowns and surprises – all dealt with fairly and quickly by Micky and team. I would like to call out Joachin who was amazing. We always felt like we were in the best of qualified hands during this entire process. All inspections were signed off, the last checks were written, and we now have a gorgeous new home behind the main house on that property. We were so happy with the project and trusted Micky and Joachin so much, that we immediately launched a second project of gutting and renovating a very large master bathroom for my In-Laws. That job started on September 23rd and was done the first or second week of November as promised. It would’ve been done sooner, but we had a little “client indecision” that cost us about a week or two. All in all, I would highly recommend Micky and his crew, and we plan to use them for as long as they are in business or until my family and I run out of projects."

FAQs for major renovation multiple room service projects in Irvine, CA

Gutting a house involves completely removing outdated elements, including drywall, insulation, and fixtures, to reveal the underlying structure. This process is not only ideal for a complete remodel but is also critical in emergency situations such as flood damage where compromised materials must be replaced immediately. Contractors follow OSHA-approved safety measures throughout the demolition to ensure a secure work environment. This method provides a fresh, safe canvas for any future renovation.

Gutting a house is a cost-efficient choice. Home renovations cost between $20,000 and $88,000 compared to the cost to build a new house of $122,500 to $411,500. The reduced cost stems from retaining the existing structural framework while updating the interior. Factors such as house size, material quality, and labor directly influence the total expenses, making a gut renovation a financially smart decision.

The cost of demoing an interior is worthwhile because gutting a house creates a completely safe and refreshed environment by removing toxic or damaged materials like asbestos, mold, and deteriorated components. Professional supervision ensures all hazards are properly managed and health and safety standards are met. This process revitalizes the home's interior and can increase its structural integrity and overall value.

Remodeling a bathroom costs between $6,640 and $17,600, with high-end remodels exceeding $30,000. The final price is directly influenced by the quality of fixtures and design features—modern tiling, advanced plumbing, and custom details all add to the definitive expense. By selecting superior materials and design elements, homeowners ensure both functionality and a remarkable aesthetic upgrade.

Kitchen renovations range from $14,500 to $41,500 when the original layout is maintained. However, changing the layout by removing load-bearing walls or upgrading to premium appliances directly escalates costs, often adding over $1,000 per modification. These precise enhancements reflect the high-quality standards and result in a transformative and efficient upgrade.

A full gut renovation typically spans between four months and a year and a half. This period accounts for the permitting process, material procurement, and the overall scale of the project. Every phase—from demolition through rebuilding—involves careful planning and execution to meet deadlines while ensuring the work adheres to safety and quality standards.
