"We hired Groundworks to install a sump pump, expecting professional work and peace of mind. Unfortunately, the experience was anything but that. First, the team showed up 2 weeks after the initial visit. Worse than the delay was the complete lack of communication throughout the process ? getting updates or even basic responses was frustratingly difficult. The biggest issue, however, was the quality of the work. Their installation was poorly executed, and we ended up having to hire another company to fix their mistake ? costing us even more money on top of what we already paid Groundworks. We trusted them with an important job in our home and feel completely let down. I would not recommend Groundworks to anyone looking for reliable, professional service."

"We had a complex project to repair our sewer line both inside and outside the house. Daniel came up with a brilliant plan to solve the problem without tearing up our brand new driveway. He was extremely thorough with his assessment of all the issues and paid attention to our priorities, to minimize disruption but also to never have to deal with this again! And the pricing was very competitive."

"I highly recommend Mountain Valley Plumbing & Heating! I had a furnace installed six years ago by a different company, Steele Bros Heating, Inc. located in Denver. My furnace is a high-efficiency condensing furnace, yet they never installed the condensate drain line— a huge mistake — it's not only dangerous, but totally embarrassing to overlook such an important part of the installation! I had Mountain Valley Plumbing & Heating come out for a furnace tune up, and their technician, Scott realized the issue. The motor in my furnace was underwater due to the lack of the drain and my furnace wouldn't turn on. I called Steele Bros Heating to fix the problem, and they placed the blame on me, saying I should have had the furnace inspected and that because I didn't have them out once a year for maintenance, they would also void my warranty. I immediately called the City of Boulder inspectors to figure out what to do. They were appalled that a HVAC company wouldn't take responsibility for su"

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.
