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."

"I met Marc with Horizon when they first did a project back in 2011. They installed a brand-new kitchen in my home! I loved it and loved them, and shortly after, had them completely update two bathrooms! Again, super happy!! I had them then do some smaller projects, removing a ceiling soffit and rounding out the ceiling in a way that even Marc was super impressed!! Later, I had them remove a chimney from the family room, which created a whole new space in my home!! I was set for a while, but when I decided I wanted an attached patio cover out back, of course I reached out to them again. We discussed what I was looking for, what was available, and came up with a great plan.

"Excellent. My house is 70 years old & really needed to be updated. This was a scary process for me. I’ve never been able to afford to hire anyone to do any kind of remodeling & was scared of stories from family & friends who have been ripped off having any work done on their houses. I was really impressed with the ideas Dereck had for my bathrooms & especially for my kitchen which made no sense. He took me shopping to pick out materials & with his knowledge & expertise guided me with my choices for tile, flooring, fixtures, etc. I love all of the men who did the work. They know what they are doing & were really meticulous making sure that everything was done to perfection & they cleaned up after themselves everyday. This has been a very long process because of course they ran into problems with some of the plumbing & then had to repipe the house because there was no water pressure. The bathrooms & kitchen have all been totally gutted & redesigned. I love the way it’s all turned out & so glad I went through all this construction including the frustration at times LOL.It was totally worth it."

Barndominium Builders questions, answered by experts

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

Green homes are often more expensive to build, averaging around $200 per square foot compared to the $150 per square foot you’d spend to build a standard home. However, green homes can save you money on your utility bills by consuming less energy or creating energy using solar panels or wind turbines on-site. They’re more expensive to build, but they often end up costing less in the long run.

Modular homes are cost-effective, energy-efficient, and faster to build than traditional homes. They also offer customizable designs.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.
