"Quality work and a reasonable price. Highly recommend!"
"I had a customer on a septic with a backed up sewer on a Saturday morning, upon arrival I noticed the septic tank needed to be pumped out, gave these guys a call they were literally right down the street and came over in 10minuets flat. Very polite and professional workers who went above and beyond helping us to figure out why the sewer is backing up. I highly appreciate these guys and will be recommending them to all our customers. Great job guys I was super proud of your service it was a pleasure to meet you."
"Great group of guys! I got a great price for services provided. Workers were prepared, respectful, and professional. 5 stars, would septic tank hunt with them again."
"Matt at A-1 is reliable, professional, and gets the job done right. If you need sewer related services done quickly and thoroughly, he's the one to call. He also does a host of other digging-related services such as excavating, water line locating, etc. so be sure to keep him in mind for those as well. Highly recommend his services!"
"If I could give this company 10 stars, I absolutely would. As a real estate broker, I was initially given an estimate by Tapco but chose not to move forward due to their lack of understanding of my specific needs with this seller. I decided to reach out to A-1 Testing, and it turned out to be the best decision. Katie, in particular, has been exceptional. Her professionalism, attention to detail, and outstanding customer service set a standard others should follow. She answered every call promptly or returned it within the hour, provided thorough explanations, and gave me consistent end-of-day updates. The entire process was seamless and efficient thanks to her. Moving forward, A-1 Testing will be my go-to company—especially as long as Katie is part of the team"
"Matt and the A1 Testing team are the best in the business, period. They are reliable, honest, and provide a very high level of service. As a local Lake Tahoe and Truckee Realtor, I use them often for PUD sewer lateral tests, septic pumping, and they have even installed new septic systems for my clients. In addition, they have fixed broken water lines and helped clients when they are in need. A1 Testing is the best of the best and if you give them your business, they will honor your trust and complete the job quickly and on budget. They are always my first call and they should be yours too."
"Matt and his crew saved us! They were onsite within the hour after our sewer backed up and would not drain. They stayed until after dark to rebuild our sewer lateral after removing FOUR tree roots! I assumed we would be stuck in a hotel for the next week and they fixed us up within 12 hours at a very reasonable cost. Thank you so much A-1 testing!"
"From my first contact with A-1 Testing Maintenance, Inc., I was impressed by their excellent communication and customer service. They assisted me in coordinating the sewer inspection to comply with a short escrow, and even took pictures of some icicles (huge) hanging from the eaves and provided suggestions for ensuring that they did not fall into our sliding glass doors. I would give them 6 stars!"
"Matt came highly recommended to me by multiple vendors here in Truckee. Although we didn’t require work completed by Matt and his team, Matt generously offered helpful advice and guidance to us over the phone. I feel confident the A-1 team has its clients best interest at heart and plan to partner with them for any future work."
"Matt with A-1 testing goes above and beyond by addressing a wide range of services promptly with professionalism and ease. He has never let me or my clients down and I look forward to working with him again in the future."
"In a year and area where contractors are inundated with work, we very much appreciate businesses that are dependable and do quality work. We didn’t have a big job although things didn’t go as smoothly as anticipated, no fault of theirs. Thank you Matt for completing our job at an affordable price. Highly recommend!"
"Matt & his crew are the best! They came out to look at a problem we had with a sewer pump lift station at one of our rental properties. The same day they had the system up and running with all new equipment installed! We are thrilled to have them as my go to contractor. Professional, fast response and no-nonsense. They get the job done!! John"
"Based on our experience with A1 Testing Maintenance Inc in testing, fixing, and upgrading the sewer lateral to our cabin at Soda Springs, CA, my wife and I highly recommend them for sewer installation, repair, and testing. Matt and his crew proved to be skilled, professional, polite, friendly, and ultimately completed the project at a very reasonable cost. For those who would like more detail, the following summarizes the project work completed by A1 between July 15 and August 31, 2020: Our family is in the process of selling our 40+ year old cabin at Soda Springs and we needed to have the sewer lateral tested and certified. We called A1 Testing Maintenance Inc for help. Matt showed up promptly as scheduled, and climbed down into our crawl space with his TV sewer scope. With the scope he found one buried cleanout 30 feet from the cabin, which we dug out. Using this cleanout for subsequent access, Matt determined that there were no other cleanouts on the line to the main, making it impossible to test for leaks. I then asked him to install two cleanouts, one by the street and one next to the cabin foundation wall, to allow for testing the entire line. With the cleanouts in place Matt found that the line was leaking badly. He located the leak, replaced the fractured pipe where it leaked, installed cleanout covers, worked with DSPUD to complete the certified leak test, and finally, paved the portions of the driveway that were dug up. In completing the work stepwise and zeroing in on the problem area, I estimate that Matt saved our family several thousand dollars by avoiding the need for excavating and replacing the entire 120-foot lateral. Throughout the project Matt kept me informed of his progress and consulted with me via email, phone calls, text, and photos, patiently allowed me to work with him and ask questions when I wanted to, and kept meticulous track of his hours and expenses."
"Our real estate office has used Matt with A1 recently and we found that he is easy to communicate with, does a good job and his pricing is competitive. Matt was able to test despite the deep, heavy snow we have been having. We found that he is quick to respond and easy to schedule. We do not need to reach out to him every time for a quote, he just gave us his price sheet that we can conveniently send to the clients right away. He also sends photos of damaged parts that he replaces. We'll continue to use and recommend A1!"
"Matt and his team are extremely knowledgeable when it comes to anything sewer. They are our first call anytime we need a clearance and have an issue. They are quick to respond and work you into their schedule asap. We love Matt and A-1!"
"We hired Matt with A1 Testing for our own personal sewer test on our home in Truckee. Matt was responsive and completed the work in a timely manner. He was so good that we couldn't even tell he had been to the house! No digging or messes left in site. I highly recommends Matt and his team at A1."
"Matt was exceptionally professional and easy to get a hold of. His knowledge was very valuable and helpful! We spent weeks trying to get a hold of someone and Matt was the first that picked up the phone! Our inspection passed in no time when we were in a time crunch."
"Matt has done a great job each time he has worked on our home. His crew was always on time, professional and worked hard to get the job done on schedule. I highly recommend A1 Testing Maintenance Inc for any general repair or septic needs."
"Matt Wied is professional and knowledgeable about sewer pumps. Our sewer pump would get stuck in an on position and the alarm continue to go off. Matt adjusted the floats and rearranged them to prevent them from getting tangled. Thanks for fixing this issue in a timely manner Matt!"
"Matt at A1 is very professional, prompt and thorough. His knowledge in his trade is exceptional. If you need any Sewer Testing, maintenance, and sewer line repair, Call Matt at A1, you will be very pleased with his service."
"Matt from A-1 saved us. We needed to get a sewer test in order to close on a home and he came out, dug out tons of snow, and got the test completed in time for us to close. I called around to other companies before A-1, and just about all of them were way too expensive, or flat out said the wouldn't do the work due to all the snow. Highly recommend Matt and A-1 Testing / Maintenance."
"Matt responded immediately to my request and completed the job promptly even with recent heavy wet snow on the property!"
"Matt was very easy to communicate with and very responsive. He completed the project quickly and went above and beyond to help out beyond the initial scope of work. He was a please to work with and I highly recommend his services."
"I have been using A1 Testing for several years now and they keep getting better and better. Matt does a great job! Being a busy contractor, its nice to rely on a business that will get the job done quickly and professionally. I'd recommend A1 Testing to anyone that needs a sewer line test or a simple inspection done!! We were able to install this new clean out and get inspected right before getting buried in snow thanks to Matt."
