Etymology of ‘Apex’

I’ve always enjoyed etymology, the study of where words came from. How do we end up with words like ‘fascination’ or even ‘etymology’? Luckily, we live in the age of Google where we can now know that in the typing of a few keys and a few clicks of the mouse/taps on...

“Ulissa was great to work with. We had 6 companies come out to give us a quote for a sewer line repair. We found the issue during an inspection while selling our house. Out of the 6 companies onky two showed up when they said they would apex and tipping hat. Apex was not the least expensive quote but by far we felt like they were the most honest with us. They were also half the price of several other companies for the work we needed done. It was crazy how far apart the quotes were and apex was at the lower end for price. They worked with a tight schedule so we did not need to move our closing date. They had the sewer line replaced in a day and did a great job cleaning the site up. They were always so nice to talk with on the phone. I did end up speaking with at least three different people and the experience was the same with all of them. I would recommend them and will be using them for any future plumbing jobs I have.”

“Apex was the only place out of having 6 different plumbers (snakes, jets, you name it!) come and actually diagnose, find and fix the problem. They were quick, timely and great with communication throughout the project. Highly recommend!”

Lisa N.

“I have used Apex four times now for sewer repairs, replacements, and also to fix others bad work. They make the process so easy. You call, they handle the rest! Being in real estate my reputation is very important in the community. Before I hired them the first time I called four other companies. They came highly recommended from other agents in my company and their pricing was always better along with their work. Now that they have a proven track record of success, I wouldn’t trust the work with anyone else!”

Paul A.

“As a Real Estate Agent, I have had the need to facilitate several sewer repairs and replacements in SE Denver. Apex has performed at least 4 replacements and 2 repairs for my clients throughout the past 5 years. They are always professional, courteous and responsive. I appreciate having them as a resource. Thank you Apex Plumbing.”

“We were dealing with a time deadline for the work we needed. Apex was easy to get ahold of. They were quick to produce an onsite estimate, and they were able to put us on their schedule right away.”

Marty G.

“Apex was quick to respond to my questions and very reasonably priced. My main line replacement was not an emergency. I was able to do research and get several quotes. A couple of them came in at almost double the quote I received from Apex. The crew that did the work and everyone in the office were good to work with.”

Doug W.

“Apex Plumbing epitomizes what a great company should be! They are professional, competitive and always provide first class service. They always exceed my expectations and are by far the best company in their field!”

Frank G.

“I really had a wonderful experience with Apex plumbing. I worked with a man named lyric black who was an estimator but who really saw us the entire way through the project. We had a break in a line Apex explained what the problem was and came up with cost-effective ways to resolve it. I am more than satisfied with the work they did… Well done Apex plumbing.”

Merinda W.

“We recently used Apex Plumbing to fix our sewer line and they were so professional and affordable! We were quoted nearly $20,000 from “the other guys” and Apex came back with a MUCH more affordable quote. The work was very well done and they made scheduling a breeze. HIGHLY recommended!”

Louise W.

“Apex did an excellent repair to our sewerline. This involved jackhammering the basement floor, installing new pipe, laying concrete and also digging up old pipe and replacement outside. They were prompt, courteous, and very careful with our new carpet. Lyric Black is an outstanding representative and is extremely knowledgeable. My husband and I highly recommend Apex Plumbing.”
