"Accu Level overpromised and underperformed. We reached out to have a simple job performed as part of selling our house. From the start, we were told the work could be performed prior to closing. Due to timing and this promise, we did not get any other bids. Upon receiving the contract, we paid the deposit within one hour. From this point on, there was no communication from the business that was not initiated by us. We texted our rep and called the office every day from this point on to see when the work would be scheduled. There was no proactive communication whatsoever. Finally, one day before closing, our real estate agent demand a date to be scheduled and it was scheduled two weeks after closing. Thankfully, we had a flexible buyer who was willing to close without the work being done. On the day the work was supposed to be scheduled, with no notice, it was postponed for another week and the buyer had to find a time to reschedule. This had to be communicated to me by my realtor and not the business. After the work was done, I reached out to our rep to explain how disappointed we were with the customer service. This was verbatim his response: "Please understand this is not our normal scenario and there were people let go/had responsibilities changed because of it." I asked to speak to his manager. Upon speaking with the manager, he said they weren't willing to do anything to make amends for the lack of customer service even with his rep openly admitting that they did not meet their promises. The manager quoted back terms of the contract to me that they are allowed to reschedule and I explained that this was not a contractual dispute, but a complaint about customer service when an employee openly admitted fault and he was not willing to take accountability for his employee. I asked to speak to his manager. This conversation happened two weeks ago and I'm still waiting for that call. Don't use this business if you want any level of customer service."

"n…do not walk away. Run. Run. Run. Our unfortunate experience with Ayers Basement Systems began with an impressive sales pitch. Our sales person was Robert. He had a PowerPoint presentation and explained to us that we would not have to worry about a wet basement ever again. That was huge because we had been wanting to finish our basement for sometime. Previously, it would leak around the window just enough to keep drywall from staying dry. We were offered a discount for signing the contract that same day. Overall, the estimated cost to us was $5,600. This price did include a permit they said they would have to pull. They went ahead and scheduled us for the next week. They informed us we would need all of our furntiture and stuff moved away from where the pipe would be installed. That was a pretty huge task due to the amount of “stuff” we have in our basement. The morning of our appt, with all of our stuff moved in such a way that no one could easily access anything (home office, computer, bills, etc), they called and rescheduled. The soonest they could get us in was an entire month out. The second appt was made and once again, they rescheduled the morning of. This was extremely inconvenient, however this wasn’t even the tip of the iceburg. Over a month after signing the contract, we finally had Ayers come to our house. We were taken aback by how young the four workers from Ayers looked. We told them that we had dogs and cats. Both were put up in rooms where they couldn’t bother the workers. However, once they left for the day, our gate was left wide open. Luckily when we let our dogs out, they didn’t notice the open gate. Another issue we had is that they left the front screen door propped open. It was a very windy day in April and the wind blew our screen door off the hinge because it was left open. The workers were there for 2 whole days. In that time they jackhammered our concrete floors, installed a pipe from the leaking window all the way to where our sump pump pumps water outside. We were told by our sales person that they would jackhammer larger pieces of concrete and put them back with a very minimal seam. What we were left with was a huge trail of uneven concrete work that followed the pipe and it was a good foot wide. The concrete was so uneven that a piece of tile wouldn’t lay correctly if we tried to do so. Then we looked at the work around the window. They put holes in the concrete to the outside of the house. They was a piece of plastic blocking a larger hole that was not flush to the concrete. Even now that piece of plastic allows the most water in. To explain that absolute absurdity of what they did is a hard task. There was rag blocking a pipe to the outside. We have no idea why but it was stuck all the way in with purpose. The outside pipe isn’t even connected to the pipe that goes to the sump pump drain. Now we have new leaks that are all over the basement. They basically opened up an entire new area for the water to go. We had a plumber come and look at the pipe and he dumped over 5 gallons of water into their pipe (drains into the sump pump area) and absolutely nothing came out of the other end so the water must be draining to other areas of our basement, causing the leaks that are popping up everywhere. So, what was the purpose of this system? When the kids left, they tried to collect the full balance. They wanted payment for a system that has ruined our basement. We refused. The sales person, owner, and a few other people from Ayers contacted us. The only thing they said is that they would come back out and “fix the problem”. At this point they have drilled holes into our house, broke up concrete, and made the leaking go from one to area to the majority of our basement area. At this point we want them to never touch our house again. They were condescending in every way. We were told that they would have a really good team come to our house to fix our problem. How many times do we have to have someone come to our house before we get a good team? Shouldn’t all of your teams be GOOD TEAMS? Ayers acknowledged they messed up. They said it was their fault. They only wanted to send more people into our home to what????? Fix the huge holes and jacked up work? Why would we trust them again?? At this point we had read some other complaints about Ayers. One said to check your permit. We did. No permit was ever pulled and yes, they did charge us for one. Then, they argued with us about needing one. We had checked with Mason County building inspectors and were told that we did need one. Ayers assured us that they didn’t (after charging us for one). Come to find out, they were told they needed one and quickly pulled one. So, all of this work was UNPERMITTED. They played that down like it was no big deal. The VP of Ayers said they have an entire department dedicated to permits. So, how does an entire department miss that? Yet, the sales person knew to charge us for one. Ayers has ruined our basement. Not only did they not fix the problem, but they made it leak EVERYWHERE. The first big rain we had after they destroyed our basement, we had an inch of water standing in our entire basement. We went from a small leak that prevented us from finishing part of the basement to our entire basement being flooded. We have to have Servpro come and clean up the flood damage and mold. We had to throw away furniture. Our son had nice guitars that had flood damage. We had electrical equipment that shorted out. It is unreal. They were notified of our predicament and the Vice President was nothing but condescending. So here we are with this BS Ayers “system” that is causing our basement to flood with water….done by (apparently) the “non-good team” consisting of only kids. All work was performed UNPERMITTED which means we have to report the unpermitted work when we sell our house. The kicker is that they are using scare tactics and threatening to put a lien on our house to secure the final payment. My question to Ayers….final payment for what? For the extra water in our basement? The big holes drilled into the concrete to the outside of our house? For the furniture you caused us to have to get rid of? The mold you caused? BTW, the plumber that looked at Ayers’ crappy work (that discovered the drain leaks everywhere instead of going to where it is supposed to go) also was able to figure out the original issue. We followed the plumber’s advice and it was fixed with a total cost of $450. So, like I said before, run away from Ayers and call someone else. Possibly, call a good plumber. Check yelp reviews. Ayers pays for their bad reviews to go away on certain platforms. We sure wish we had checked yelp"

Structural Engineering questions, answered by experts

A construction manager is particularly useful in the case of a large-scale build with custom design elements, so it’s usually worth it to hire one. They can help manage your budget, maintain quality control, oversee timelines, and navigate unexpected hurdles. While construction managers are pricey, they can actually save money in the long run by identifying cost-saving opportunities and ensuring the project stays within budget.

Yes, a one-story house can have a load-bearing wall. The load-bearing walls in a single-story home are usually the exterior walls. If the house has a basement with exposed walls, the arrangement of the beams can help indicate what walls are load-bearing.

While concrete walls do not need to "breathe" in the traditional sense of the word, they do require waterproofing and dehumidifying methods, particularly in basements below the water table. Concrete both contains moisture from its initial installation and can absorb water when exposed. Ensuring proper basement ventilation , installing a vapor barrier, and controlling water exposure are all important tasks.

Yes. Foundation walls are always load-bearing.

Yes, unresolved damage can decrease property integrity and market value.
