This place is amazing!!! The owner and their team are the best at customer service and recommending people and services that meet your means and needs. Plumbline Services came to my grandmother's house and quoted her a $9000 patch job, thankfully for the amazing and honest work mainline did they found Plumbline was lying and trying to scam an elderly person for thousands of dollars. Thank you Mainline and the amazing work you do and we are so thankful for you! read more

This company is terrific! From the lovely woman who handles the phone, Hannah, to the guy who came out to my home (John), I experienced wonderful customer service from start to finish with Mainline. After having my sewer lines cleaned out by the terrific Joe McCloud from Diamondback Drains (recommended as step #1 by Mainline), I had the Mainline service rep come out to scope out my line. He did a great job and explained every step of what he was doing. He scoped my sewer line out to the street and found that there were no breaks or cracks or irregularities anywhere in my line. A different and well-known plumbing company had tried to tell me a year ago that all of my pipes were cracked and needed to be replaced---to the tune of almost $15,000. Thank goodness I resisted that other company's dishonest, hard-sell pitch. Mainline is efficient, reasonably priced, friendly and HONEST. If you want great service and do not want to be lied to or price-gauged, call Mainline. read more

Matthew at Mainline Services came out to scope our line. He showed up on time, let us watch the video scope, explained what he was doing/seeing and and was patient with all of our questions. The report was written up and emailed the same day. We were very pleased with the services, including communication from the office and a follow up call. read more

They changed there initial response to my review, to make it look as though there was a compliance issue with the reviewing customer (when in fact you were talking about another issue/mistake you made with another customer) You made a mistake twice, and it really shows the ethics of your company. read more

Sewer talk is anything but sexy and is downright depressing financially. When our main line backed sewage into our house, we weren't prepared for the news of a belly in our line combined with an offset. We called Mainline for a second opinion/camera scope. The woman who answered the phone was so nice and helpful. She recommended several contractors that could do the work on our sewer line. In addition, we set up a camera scope. Matt P came out to do the scope and was awesome. He was really professional and took his time explaining what was happening in our sewer line as well as options for us. He gave us really good advice and his write up was very comprehensive. I was able to take his report and give it directly to Ed Holcroft who was one of their recommended vendors. He was awesome too and just finished the work on our line today. In short, plumbing work is not fun to pay for but is of course essential! I would trust Mainline, Matt P and Ed Holcroft with any job. read more

I'm so glad I called Mainline Services for my sewer scope. They do not complete repairs, but rather provide an unbiased report of exactly what work needs to be done and a general estimate of repairs. They are incredibly knowledgeable, friendly and were able to answer all my questions. After completing the scope, Mainline provided me with a list of preferred vendors. Ed Holdcroft (Ed's Sewer and Water Repair) did an amazing job repairing our sewer line. His quote could not be beat, literally half the cost of other quotes I received from vendors outside of the preferred list. Ed is a downright honest and super nice guy. There really needs to be more vendors like him in this world (I wish he had a Yelp page so I could write a 5 star review for him). I would also note that I got quotes from other vendors on the preferred list and they were all incredibly competitive and significantly lower than non-preferred vendors. Thank you Mainline and Ed for helping me navigate through this process and doing such stellar work! read more

Mainline Services saved us more than $6K on replacing our main sewer line. They are the BEST. I suggest to anyone needing to get any type of sewer scoping done they call Mainline for an independent scope. After nearly being ripped off by a plumbing company who quoted between $13-20K+, we called Dewayne for a second opinion. We're so glad we did! - He was extremely thorough. - Explained everything in terms we could understand, walked us through problems and options step-by-step, and gave us the should-and should nots. - Pointed out problemmatic work done by other company (including bio hazards and things not done to code). - Gave us a DVD and link of the sewer line scope. - Communication was top-notch (prompt, courteous, professional) -- not just with Dewayne, but with his office. - Gave us their preferred vendor list (they gets nothing for referring other companies), which gave us the opportunity to have multiple businesses bid on the job. By working with Mainline, we truly felt we had an advocate and a partner in fixing a major problem. Cannot recommend them more. Definitely worth the small investment. Do it! read more

I have used Mainline Sewer Services Inspections in evaluating several properties in multiple Denver metro counties. I never buy a home without inspecting the sewer lines--amazing what surprises and revelations one finds, especially in this area of shifting soils. A missed problem could cause the buyer unpleasant surprises to the tune of thousands or worse due to an impending problem. Dewayne's inspections were thorough & technologically up-to-date . Dewayne takes pride that his inspections and report are done to standards that hold up legally if need be. They do NOT do repairs or installations so unlike some others, you can trust their evaluations to be objective. read more

We were about to get ripped off by a company. Mainline came out and did another analysis and we realized that we did not need to be replacing our entire sewer line. Even if we had to, we had been quoted 20k over what a sewer line replacement would have cost. I sincerely appreciate this company and their service. They came out quickly, the day before Easter. I would highly recommend and will be using them in the future. read more

I will start by saying I call this company often to help my clients get a real/honest opinion of their sewer line. Often times in the real estate business sewer lines are scoped by unlicensed inspectors that don't understand the complexities of a sewer line, this is where mainline comes in. Mainline is my first call to professionally scope and recommend what we are to do next. Often times they disagree with the inspectors findings and help my clients feel at ease about their sewer line. I share all of this because this company is extremely honest, upfront, trustworthy and easy to work with. They are also priced very well for the work they do. I highly recommend them! read more

As a real estate agent my clients hire someone to video sewer line with every purchase....these guys called it wrong both times (2 different sales) i never again need their opinion! read more

Summary: I have not come across a company that is as honest as this one. I highly recommend them! Details: We had a backup in our sewer line that caused damage to our finished basement. We called a widely used company here in Denver that came out to do a sewer line scope and gave us a quote of $30k to replace the line. That's not a typo. Apparently, our line was longer than the typical line, and the line had roots and was in bad shape according to the plumber, and the line needed replacement. When we asked the company for the DVD of the scope work (which was included in price paid), they refused to provide it. This told me that they simply didn't want any evidence that would go against their obscene quote. After many tears shed, we decided to call a second company for an independent assessment of our sewer line-meaning a company that does not do repairs. After reading reviews, we decided on Mainline Services. Dewayne came out to see us and it was apparent from the beginning that he was about as knowledgeable as it gets. On top of that, he was very polite and friendly. We scoped the entire line, and we viewed the video together on a much bigger screen. We found NO major issues. The only thing we'll need is a cleaning to clear out some roots. That's it! Every question we had was answered in depth. We paid $99 for the scope, and what we received in return was exceptional service and a relief that I can't put into words. Thanks Dewayne! read more

SAVED ME 17,000.00 !!!!! NICE TO KNOW THERE ARE HONEST PEOPLE OUT THERE! After many plumbing issues, inspections, line jetting, and quotes of thousands of dollars I decided to have Dewayne from Mainline services come camera my lines for another opinion. He fit me in between a couple of jobs, was so professional, explained what would be done & furnished me with a CD for viewing. After a 17,000.00 quote from a previous inspector with another company......Dewayne confirmed that I did not in fact have an issue with a broken pipe, but a blockage that was not cleared resulting from our jetting not being done completely to the main sewer line which Dewayne easily dislodged. He saved me a bundle of money that would have been paid by an unsuspecting customer for a false diagnosis and bid!!! LOOK NO FURTHER. . . THIS CO IS HONEST....A RARE FIND! read more

In the past, we have received nothing but excellent service from Mainline. We have used them on 4 different occasions to do scopes for different properties we've purchased. The most recent time, however, was a swing and a miss, and regrettably, they have declined to accept any responsibility. We purchased an older house that had an addition built on many years later, and as a result, there was more than one drain line going into our main line out of the house. Dewayne came out and scoped one of them, and told us everything was in great shape. We came to find out after moving in that there was a severe blockage in the other line of the house causing major drain back ups, and necessitating us having our concrete patio broken to access and replace underground pipes. We called and asked why they didn't scope both lines coming off of the house, and Dewayne's response was to say that if we wanted the other line scoped, we should have told him it was there, and requested that he scope that one as well. Based on our previous experiences with Mainline and the high level of expertise I believed them to have, I wouldn't have thought they would need direction about which lines coming off of the house needed to be scoped. I'm not an expert on plumbing or sewers--that's why I hired one! The end result? We didn't have any inspection objections on the plumbing because "everything looked great," and now we're on the hook for a several-thousand dollar pipe replacement due to a months-old blockage that should have been found at inspection. We will not utilize the services of Mainline in the future. read more

Similar to below I was disturbed by the response when trying to get several bookings for this service. I had asked to speak with Renee as I had in the past only to be told by the new manager that Renee no longer worked for the company. After a mild query to why I was hung up on abruptly. Shortly later Duane phones back harassing me for business and makes very personal comments about his former employee, never mind berating his new "office manager" for having no more responsibility past answering the phone! I politely declined the service. Christian? read more

Sewer scope, for home buying inspection. I was thoroughly impressed. They clearly knew more than was "required" to do the job and were able to explain details to a degree that made me feel completely confident in their findings. Highly recommend! read more

I asked Mainline to come out to my house for a second opinion after another plumbing company, JD's plumbing Claimed I needed a new sewer line to the tune of 12 grand. Only to find out there is nothing wrong with my sewer line! Not only did Dewayne bring the latest technology , he was efficient, polite and very informative! I highly recommend his company to anyone in need of a honest and reliable sewer scope! read more

We called Mainline after having another company come out and they quoted that we needed $8,000 in repairs done on our plumbing. We were told that our cast iron pipes were flaking and cracking and needed a liner put in. We were also told by the previous company that we would need to excavate our garage!!! We needed a second HONEST opinion. That's when we called Mainline. Duane arrived 15 minutes early. He was friendly and knowledgable. He showed us our lines and explained exactly what was happening and why. We had old pipes, yes, however they were intact. We had a mineral buildup that needed to come off. We were charged a mere $99.00 and Duane recommended who to call to have our lines cleaned. We were so delighted with the services. We won't use anyone else! read more

Dewayne and his team do an amazing job! Any inspections needed, this is who I recommend. Dewayne is extremely professional, efficient, pays attention to details and is very knowledgeable. We were needing an inspection done in Florida as well and even though the company isn't based there, he still got on the phone with us, helped us figure out the problem, he was able to point us in the right direction and he even followed up a few days later to see if everything worked out. They go above and beyond and I really appreciate that. read more

Mainline services was great! From calling to get information, to making an appointment to having Matt Come out and doing the scope on the mainline was great! Uber amazing customer service from all angles. Matt was very friendly, personable and helpful. Thank you so much Matt and Mainline services! read more

We experienced two sewer backups in three months, even after outside clean outs. I called up Mainline Plumber and Matt Palmer used his investigative skills to find the source of the problem at a y-intersection that the cleaned outs were not covering. He explained the issue in detail with evidence from camera video and even worked to clean the issues with the camera. He showed the before and after and tested each toilet for clear flow. Amazing, amazing job. He is the Sherlock Holmes of plumbing issues!! I would note that Mainline Plumbing sent Diamondback Drains to conduct the clean-out. I asked the tech to run a clean-out from inside the house yet he insisted that outside clean-outs were sufficient. Yet as Matt Palmer found out, this did not solve the issue. read more

I'm a real estate agent. I have been referring these guys to my clients for over 3 years. What you don't get with them that you sometimes get with others is that the sewer line is too dirty to scope. If it is at all possible to get the line scoped they get it done. They are not overly dramatic about inperfect conditions while still providing fires with informative constructive critiques of sewer lines. read more

These guys were super responsive and were able to make it out right away. There inspection report was done quickly and thoroughly. They even performed locates on the damaged section of the sewer. The crew on-site was super knowledgeable and friendly, I'll will definitely be recommending this company for anything in the future. read more

Matt and Brian came out to scope our mainline today. They were sooo helpful!! We had been told by a plumbing company that we needed to have part of our line replaced right away for $5000, yet when the guys at Mainline looked, they identified issues in a completely different location in the line, and as it turns out, it isn't as bad as we thought. They recommended a thorough cleaning and re-scope before we make any big decisions. And we will get a copy of the video they took of our mainline. Plus, they gave us the number of a guy who can come out and clean the line out really well. Top notch service. Both Matt and Brian were very professional, friendly, helpful and answered all our questions. Plus, they were super sweet to our slightly nervous doggie (bonus points!!) All around great experience. I highly recommend this company!!! read more

We have used Mainline on multiple properties. The most recent was our property on Osceola. Mainline did the initial sewer scope before we bought the peoperty, there was one low spot they recommended fixing. We did fix. During the sale of the house, the new buyers did another scope, they found cast iron debris in the line. Our contractor tried to tell us it was plaster. Which we knew it was not. The contractor had his plumber come and try to rooter the drain. He assured us he got it all out. When we asked Mainline to re-scope it for us, they found the debris still in the drain. Because we are such good customers, Tommy tried several things to get the debris out of the line. Tommy spent allot more time on the drain, went over and above what I thought he would. Mainline is a great company to work with and saved us Thousands of dollars on repairs. I would highly recommend Tommy and mainline for all your sewer and drain needs. read more

Another company had come out to do a locate and when we couldn't find the sewer line Matt P from Mainline came out at 7am the following day. Matt was on time, professional, and best of all, provided a clear and precise locate. Thank you Matt P.! Matt also provided some insight as to how best complete the project saving me time and money. Call Mainline before you start your sewer line repair! read more

Just got done with Matt the technician and WOW!! Amazing, thorough work. Very pleased with everything - Bottom line: Great Company! Thank you! read more

First off, you should know that I did not actually hire Mainline for the plumbing work I thought I needed at my house. I left Dwayne a voicemail around 7:30am when I realized I was having back-up issues in a basement bathroom - he called me within an hour. After describing what was going on, Dwayne actually referred me to a different plumber with a specialty in the area I needed. He also provided valuable advice and recommendations, as this was the first time I've dealt with mainline issues. The plumber Dwayne referred me to is insured and trusted, and was at my house by 10:am, problem fixed by 10:30am. I'm SO happy with the outcome. Will be keeping Mainline Services and Dwayne on my short list of excellent contractors to work with in the future. read more

Tremendous service, expertise and integrity! Mainline got to our property quickly after the prospective buyers of our house claimed to have found a flat spot in our home's sewer line where it ran under a city street that "had to be repaired." Michael Nutt from Mainline did an inspection and found the area in question wasn't as big as was claimed, was not impeding water flow, and did not need to be repaired. He had seen this shady tactic before and knew we were getting taken. We highly recommend Michael and Mainline. read more

Dewayne and Robert were extremely responsive, helpful, and the best value by far for plumbing services. I would highly recommend.

I have used this company for years and it used to be great, when it was just the owner Dewayne. But he now has a bunch of people working under him and does not do the sewer scopes himself. Recently we had a sewer line scoped by one of his employees, the employee could not get into the house from the clean out, so he just went inside and scoped out. He said the line was in great shape. Well, a few weeks later the buyers moved in and toilets started backing up, causing major issues and an emergency call to a very expensive plumber. Turned out the line was broken. After this happened I called Dewayne for his help in resolving the issue. He was immediately defensive and refused to admit his employee had made a mistake. We talked about this for weeks and he was very uncooperative and combative. We wanted him to come to the house so we could discuss what happened and he said the only day he could be there was Father's Day because he lives 175 miles away. If he lives 175 miles away he is probably not very hands on on his Denver business. And it shows. After all of this I posted a review on the BBB, after which he called the El Paso Co Sheriff on me, not really sure why. Then he sent me numerous threatening text messages starting at 11:40pm. Needless to say, I will no longer be using this business. read more

I'm a real estate agent and I've been referring all my buyers to Mainline for the last two years because they don't do sewer line repairs (no conflict of interest), very organized, friendly & easy to work wit, and now I know... if anything goes wrong, they have your back!! My client recently move-in and discovered a leak that was accidentally caused by the sewer scope during inspection. I assured her, Mainline is a great company and they would help. I was absolutely blown away when the owner of the company, Dwayne, showed up within a few hours, took exceptional care of her, paid to have everything repaired, and even paid for carpet cleaner. He even offered to put her up in a hotel room. I'm 100% confident in referring this company, they will take care of you!!!! read more

Had the great opportunity to work with Dewayne. He is far and away the best most honest person I worked with during our house buying days. Very prompt, very knowledgeable, and trustworthy. I was referred to him by my real estate agent and to our surprise was our favorite inspector/service that we worked with when we were inspecting everything. Dwewayne not only will be honest with you but will only recommend the services/repairs you need, no upselling. Great guy, great service, the new standard for home service providers. Thank you read more

Matt came out, scoped our lines, and gave us the information we need to get our problems taken care of.

Thank you Mainline! I wanted to get an impartial third party when it came to my sewer scope. I had a backup and called Roto Rooter. BIG MISTAKE. $650 later... I got a bad snake and my scope guy told me that it was going to cost $14,600. I cried... Lol. I was so stressed out! The Roto Rooter guy was super uncomfortable and then he told me that... I didn't NEED to do it right away. Then I tearily said okay. I'll do it in 2 months. Then he reassured me that there was no TRUE timeframe to get it done. Weird, right? I talked to my parents and they said to get a second impartial opinion. I decided to go with Mainline, because of their great reviews. Guess what? I saw huge roots that weren't even snaked! No wonder the water was pooling. He took his time explaining everything and the different falls and what to be concerned and what not to be concerned about. I DON'T HAVE TO FIX ANYTHING! I do need to get things cleaned again. I honestly don't trust Roto Rooter to do the job again. I'm going to go with the guy Mainline recommended. I'm not paying $450 to get a snake... I've read many reviews now and know that the going rate is about $100-180. It was recommended that I do this once every 1-3 years. I feel good about things again. read more

If you are a homeowner or considering buying a house you have GOT to use this company to check out your sewer lines! WOW! I learned so much from them! We were explained everything and I always love it when a company educates you on how NOT to get ripped off by other companies by informing you of industry tricks not to mention how to not get scammed by the city either! At $7k and up in fines, thats crucial to know how to avoid! For $99 how can you loose?!?! Reallllly really happy AND empowered here! read more

Mainline (Dewayne) was on time to the appointment, clean, professional and very friendly. He provided thorough information and documentation to include a same-day DVD/video of our freshly examined sewer lines...that we will never watch. BUT, it's good to have on record. I'd recommend him without hesitation as he offered us assurance regarding our home purchase for a fair price. read more

Was referred by a friend, helped us out with our plumbing issues and really made things a breeze. RotoRooter aint got nothing on this guy!!!!!!!!!!!!!!!!!!!!!!!! read more

Again, 2 certified plumbers disagreed with this quack and the sale of the house went through. I did not threaten this guy to change anything in his report but merely questioned the validity of it. The sale speaks for itself 2 plumbers won over a quack. read more

Super responsive and great service. Called to get a sewer scope done on a short time frame and they responded right away. The technician was friendly, professional and I feel great about these guys. Fair price as well. read more
