"Service tech arrived a few minutes early and got right to work. He diagnosed the problem very quickly and then replaced the sumo pump and waited until it had fully drained the sump pit. Overall excellent work!"

"Jesse did the french drain around the house with added sump pumps to take the water away from the house. He also added the new water break for out side and back flow and series of other jobs. He was so good that I hired him for other jobs as I listed some of them on top. He is professional, knowledgeable, honest, respectful, caring and shows up as he promised. If there was an obstacle he was very communicative about it. His prices were compatible to the market and in some cases lower. I highly recommend him since I had to deal with a lot of other contractors and not any of them had the virtues he demonstrated. I am very satisfied with his work and will hire him for future projects."

"I had an issue with my kitchen sink pipe / washing machine drain that was clogged and caused a backup and overflow into my utility room. There was also a crack in the elbow joint for the pipe that was caused by the backup, which was leaking as well. I called Mr. Ennis (James) around 7am to schedule an appointment, and even though it was blizzarding outside, he was at my house the same morning. James quickly unclogged the pipe, and at the same time found that it was leaking at the base of the pipe where it went into the concrete in my utility room (The prior homeowner tried to mask the issue by spraying foam insulation around the base of the pipe). He was able to chip out the concrete and found 2 sections of my cast iron pipe that were either cracked or rotted through completely. He was able to cut it all out, and replace those underground sections, pour new concrete, and replace the entire kitchen sink / washing machine drain pipe section all within a couple of hours. James was responsive, polite, very professional, and most of all extremely detail-oriented! As long as I live in the front range, he will be my go-to plumber and the first recommendation I give our whenever a friend needs help. I can't thank him enough!"

"Great drain clearing service by Jordan without all the bait and switch add-ons provided by the lower cost services. His charge included camera work before and after, with the best guarantee: no payment if he can't clear the line. He uses more powerful equipment than the cheaper services. Don't fall for the $95 service offered by others -- I tried them and they are a scam. They come out, use their lower power equipment unsuccessfully, and then try to get you to upgrade for major repairs. This guy is honest from the start and gets your line cleared in one visit."

"Great Joseph Rodriguez did an excellent job. We had a heart install a garbage disposal yesterday but we needed an outlet put in under the sink and Joseph came out today to do that part of the work and he was so quick I didn’t even know he had finished I thought he hadn’t even started he did it in less than a half hour."

FAQs for sump pump or interior foundation drains installation projects in Longmont, CO

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
