History

Established in 2012.

After working for another company with questionable business practices, I decided it was time for a change. I would research and purchase the very best scientific equipement, train the technicians to plumber and excavator standards and be always, «In Search of Excellence», in all that we do. Since that fateful day in 2012, Mainline has grown exponentially and continues it’s growth to educate people in real world pricing and give top rated service at one low price. Our portfolio consists of over 57 investors, over 1000 realtor database, 150 Home Inspectors. Major contract work with Lockheed, Cities of Aurora, Denver, and new build communities help us to round out our commercial side. We inspect pipe settings in wells, vacuum lines, bridges, Fiber Optic and power line shells. Our history sets the groundwork for our future with camera research in new technologies to gain more accuracy to our evaluations for our clients.

We’re selling our house and needed a second opinion on our sewer line that was fixed 3 years ago. Dewayne came out and he was honest, fair, and great to work with. We feel he went above and beyond what was expected. He even let our 5 year old look at the video of our sewer. GREAT experience. Would highly recommend.

I *highly* recommend Mainline Services. Matt came to my house equipped with two types of cameras (including a special smaller one that he ended up having to use). He was extremely knowledgeable, explained thoroughly what he was doing, and answered all of my questions. These guys are attentive, reasonably priced, and a pleasure to work with.

Mainline is simply the best! I have been recommending Mainline Services to my customers for several years now. I have never met a anyone as enthusiastic and knowledgeable about their work as Dewayne Melvin. I just completed a scope on a damaged line and a rescope on a repaired line with Matt Palmer and was equally impressed with his friendliness, communication skill with customers, and expertise. Honest and ethical work is what you will get when you call Mainline Services.

I don’t post reviews normally, but when a company that really deserves it comes around I feel obligated to tell everyone. I was being ripped off by a plumbing company and called mainline for a second opinion and they save me around 5000 dollars. Dewayne and John were both amazing when they came out and scoped my drainage. The honest and detailed info they gave me really saved me a lot of money and headache which is great when your selling a house and have enough headaches. I will use them in the future and recommend them to any one who needs a scope done.

I highly recommend Mainline Services to anyone needing a mainline scope or 2nd opinion of the state of their underground plumbing. I had my main line back up a few nights ago. Water seeped into finished areas and ruined some carpet and boxes in storage. It was around 9pm at night when we noticed so when we called the next morning we took whomever could get to us earliest. What a mistake. If only I knew at that time about Mainline Services, I would have saved money and slept better. The first company came out and after running water for 10 minutes and no backup we concluded that the most likely culprit were some wipes that were flushed the night before as we have a child potty training. Note to anyone, those advertised «flushable» wipes are not disposable. We went ahead and snaked the line to be sure and he had trouble getting it through, so we called in a scope. After the scope, they tried to tell me that I needed to irrigate to jet out the build up to the tune of $ 5800, which later was bargained down to an even 4k. Um, no. So we called in Mainline for a 2nd opinion. Robert showed up promptly for the appointment and walked me thru a lot of the video scope and advised that if there had been anything with an issue, it was gone and needed nothing except routine cleaning/​maintenance. His detail and explanations made me feel confident that he knew what he was talking about and that he wasn’t trying to sell me on something. 5 stars to Robert and to Mainline for having genuine and knowledgable teammates! Not only did your assurance save me $ 4000 but I can sleep better at night knowing I don’t have to worry about sewage seeping back up into my house.

Mainline has scoped 2 homes for me as a buyer and seller.
Dewayne does business old school (honest, with integrity, very friendly) but with a very nice, new school camera. He went far and above what he needed to do with both transactions as well and really helped facilitate the saving of much money.
Super nice dude also that I could hang out with and have a beer.
Mainline provides a rare combo of genuine, honest customer service in a culture of either increasingly contrived CS (for survey results) or completely non-​existent customer service along with really fair rates for their service.

This company did exactly what needed to be done. We had our mainline inspected and I was concerned that they inspect out to the city sewer main connection. They did just that! As well as provided a report detailing lengths and material of the pipes. They even gave referrals for companies to have the line cleaned, and suggestions at how often it should be cleaned. These guys are great.

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.

Matt was thorough, professional, knowledgeable, and fun to talk to. I also like Mainline Services because they do not do sewer repairs themselves, so they don’t have any incentive to tell you anything but the truth.

We are first time homebuyers and had a recommendation by our inspector to get a sewer scope done and they suggested Mainline services. Robert came out at our scheduled time and was extremely professional, courteous and educated us on the entire process. He did not waste any time getting to work and was done in about 30 – 45 minutes. We’re so glad for the peace of mind and the great recommendation. Would certainly use Mainline and Robert again!

Great work by Matt. He was thorough, knowledgble, attentive, and very reasonable. He located and scoped an older property I just purchased. He even came to my home after and shared his expertise with me. Good to see in an industry beset by all manner of huckster, Matt and mainline are doing things the right way. Definitely a breath of fresh air in this wild west world of sewers!

Dewayne is not only the most energetic and knowledgeable professional in the biz (we look forward to getting to interact with him), but he’s also someone you can trust implicitly (a huge gift when you’re new to the area and so many contractors want your business). Dewayne conducted a sewer scope on several houses we were attempting to purchase this summer and helped us make the right decision by finding major issues with one of the homes’ sewer. When he found issues, he articulated the exact recommended action and walked us through it thoroughly. Add to this: he is generous and cares deeply about our community. After working with us on residential, Dewayne donated a sewer scope to our social enterprise coffeehouse during lease negotiations. This gift supported our negotiation position and is a huge asset during engineering and build-​out phase. He always walks you through details, files an official report, and provides a DVD of the scope for your records. And, he’ll make your day. Choose Mainline and Dewayne. It’s a no brainer!

I highly recommend Mainline Services. I had a sewer scope done at a property that we were buying. We found a $ 3500 issue (on a fairly new home) that we were able to get resolved before making the purchase. Mainline recommended the exact fix and verification steps to ensure the job was done right by a contractor of the sellers choice. The communication and follow up was excellent. They scheduled around the necessary contractors and verified that the fix was made correctly. I sincerely appreciate their work, and I am thankful that my home inspector recommended that we have the scope done in the first place.

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!

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.

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.

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!

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.
