"Thomas, sales, assured & described remedy for each concern including low spot where water pools. Admitted that they are not the low bid because they are superior in workmanship. Delayed start due to material pick-up. told it would still be dry by 5pm. Lawrence walk the project identified all issues including the only low spot where water pools. the crew worked efficiently enough to solicit and complete two neighbor's projects that same day. cracks were still very visible. Lawrence said I would have to wait 6 months and repeat the process for and additional $1500 to completely fill the cracks. The area did not dry by 5 but took over 24 hours to be walkable. I paid them in full immediately. A week later the water pooled at the low spot as before. no difference. I sent photos with an email. No response from the company. I followed up with a phone call.

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."

"Bait and switch. I obtained multiple quotes for my foundation. Dalinghaus Construction quoted me 19 piers to stabilize my home. I questioned why their competitors were quoting me over 30 piers; and they reassured me I was being over quoted by their competitors. Long story short, I went with Dalinghaus. During construction, a rep (David F) came by to drop off some tools and found that 19 piers would not be enough. They said I needed 14 more piers (totaling 33– same as their competitors). I’m stuck because I cannot leave my home half stabilized. No other reputable company would complete the job if another company started it. I was obligated to move forward with Dalinghaus. No one called to apologize for the misstep. They invoiced me and could care less how much this would affect my family. They proceeded to install14 more piers but left 14 large holes— they said backfilling was not part of the scope of work, while the original 19 were backfilled. Insanely strange why they think I wanted 14 large holes at my home. So this is where they gave me a “discount.” They backfilled the holes for free. Free? It should be included in the work. All in all, why do I have to pay for a mistake of this magnitude? I’ve tried to work it out with them peacefully but they have not provided me anything that would make this right. Only excuses why they should not compensate me. They have no integrity. They only care about their reputation at this point (they want my bbb review taken down). I would like to be compensated for the 14 additional piers that were missed from the original quote. 14 additional piers is a completely new job, not a “new work order.” They are the professional and should have done a more thorough assessment to provide me an accurate quote. Their competitors seemed to have done so but I was sadly duped by Dalinghaus. They baited me in and switched the price after the work started. $38k is a lot to lose. I have 2 small children and a home that needs to be completed. Ps. I’ve been waiting over 2 months for a resolution."

Concrete Mudjacking questions, answered by experts

Mudjacking can be an expensive foundation repair process, but in many cases, it’s well worth the investment. This is especially true if you’re lifting a portion of sunken foundation slab back into place. In that case, mudjacking can help avoid major structural damage and even home collapse by restoring the integrity of your structure with minimally invasive procedures. Mudjacking a concrete patio, walkway, or sidewalk can be worthwhile because it removes tripping hazards and makes your outdoor area more aesthetically appealing.

There is no real alternative to underpinning, although mudjacking and polyjacking are other repair methods that can add support from underneath your foundation. Rather than placing supportive piers under your structure, these involve pumping a material under your slab to lift a sunken section back into its original position. Polyjacking, in particular, is sometimes a suitable solution for stabilization issues under slab foundations, but underpinning is often accepted as the best and most permanent solution.

Most houses are expected to settle over time, but foundation sinking of more than a few inches or uneven sinking of more than an inch for every 20 feet is cause for concern. Any significant or uneven sinking should be assessed by a professional to determine the cause and perform any necessary repairs. 

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.

Boring (also known as directional boring) is one alternative to trenching when installing underground utilities. The main difference between directional boring versus trenching is that boring doesn’t require digging or disturbing the surface. Instead, it involves creating holes or tunnels in the ground and then running utility lines through the openings. Boring is less invasive than trenching, but it’s also more expensive.

By submitting this question, I acknowledge and agree that Angi may publicly display my name, city, state, and question on the website for professionals and others to see.
