"Well, it's fixed. A learning experience ? get many bids and make sure the company wants your business. Pros ? Technicians were polite and respectful of my home while I worked in meetings all day. ? The pooling water issue in the basement was resolved, and the floor is now dry; the work was ultimately completed. ? Initial estimate visit was free, but not thorough ? Senior staff came out later to apologize and review the work. Cons ? Pricing was far higher than industry norms based on later bids. ? Avoidable scope changes and price increases after work began; two other plumbers said the job could have been done as originally quoted. ? Communication issues (delayed quotes, unclear explanations, forgotten site details). ? Work quality/finishing didn?t match the premium price; two professionals asked if we had done the work ourselves. Added pictures because I don't know plumbing, so you decide if you'd want this. ? Extra fees add up: 10% financing fee (Synchrony) and 4% credit card fee."

"Contacted Henco for service of a Noritz On Demand water heater, and a next day appointment was available. Joshua arrived at the scheduled time. He inspected the unit and provided choices and recommendations of what could be done to flush and service so the unit (which was intermittent) would function properly, and the costs involved. He was very patient with my questions, and invited me to observe. Joshua also gave suggestions on proper care and that I should drain the unit during extreme freeze events to prevent damage. I would highly recommend him to any of my friends. Pricing was based on the service performed, rather than an hourly rate. The repair cost was in line with other estimates, which, like everything else, has gone up substantially over the years. based on the excellent and prompt service, I'll certainly call Henco in the future."

"Immediately responded to schedule appointment and friendly. Technician was helpful with an estimate and quickly replaced the faulty expansion tank. However, the amount of communication by phone and text from the dispatch was on the verge of nagging and the tech cancelled the appointment the morning of. Got rescheduled and it worked out though. "

FAQs for sump pump or interior foundation drains installation projects in Portland, OR

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.
