"Josh was very responsive to our questions and very knowledgeable, telling us various options for installation. He was flexible on our schedule, needing HOA approval for the exterior changes. The price was certainly reasonable. We chose a sump radon mitigation system. He even painted the piping to match the exterior--one less worry for us. The install looks great. We are going to finish our basement, and he made sure to install it so it would not interfere with the finish. It went from 4.1 (just above the standard requiring mitigation), to an average of 0.68!! (Just outside air measures at a 0.4!) We are thrilled and definitely recommend his team. My concerns for my familys health are definitely relieved. Thanks, Josh!"

"Rooter Guys installed a sump pump in my basement after we began experiencing flooding. They rearranged their schedule in order to fit us in sooner given the urgency of the project. They were professional, hardworking and kept us informed throughout the process."

"The company showed up when they said they would and completed the job within the time frame that they stated. Communication was a little rough with the field, but communication with the office was very responsive. Considering the extent of the work and the constraints within which they had to work, there was remarkably little collateral damage done. Unfortunately I was not able to witness the work before it was covered up and so I cannot comment on the quality of the installation, but can say that the company did a good job protecting the surrounding landscaped areas and seemed contentious and thoughtful in their approach to the work. I would definitely work with them again."

"I needed a sump pump repair and received two quotes. Bulletproof Plumbing and Heating was cheaper by a couple of hundred dollars. They successfully performed the work as promised and I was impressed with the quality and customer service experience that I had Todd (the owner) quote another project to install new plumbing on a basement kitchenette we were installing. Again his quote was significantly lower than another quote I received and the end result was another quality project completed by his team. Since then I have used Todd and his team for a couple of other plumbing issues. He is very responsive to my texts/calls and it is comforting to know that he will always send the same plumber (Jesse) to address our issues. It is also nice to know that I can always count on Todd 24/7 to respond back to me and treat me as though I was his most important customer. His company is definitely is worth hiring to address your plumbing needs!!!"

"Found Denver Drain (DD) through Angie list and being an old salesman myself, I reached out to the first company that left a message; that was Jeanette from DD. They could have had someone out the next day, but to accommodate my schedule he was here in 3 days. JJ was professional, courteous, and respectful, and got the job done quickly. I highly recommend DD to anyone and they are now in my contact list as my plumber MW"

"Initially I requested an estimate for a plumbing project already in progress with some challenges. Keith responded immediately to get details and schedule to come out to look at what was needed. He proposed a solution that eliminated any impact to walls or tile to replace old valves and faucets. He and his team completed the work on time and were neat and professional and results were better than I expected. There was no damage at all to what was old tile. I subsequently had him assess an old water heater and decided to replace it. It had to go into a very small areas and be upgraded to code and he was able to solution the replacement to fit perfectly in the limited space. Previously on the project we had noticed a periodic odor of gas but no one had verified a source. Keith identified a leak in the area of the furnace right next to the water heater. We had decided to upgrade the furnace and AC and again Keith and his team were able to get an order in quickly, get the install done exactly as committed and fixed the gas leak in the process. Based on the quality of work performed in each case and the expertise of the team I hired Plumbing Tree again to assess an old furnace and AC at my primary residence. The furnace had been failing at the end of the winter but I waited for summer to replace and it had deteriorated and was not safe. Keith evaluated and gave me two options and was able to get the order in immediately after I decided to go ahead. He scheduled the install within a few days. His crew was on time and completed the install of furnace and AC in one day. Again they were neat, efficient, described all the changes from the old furnace and thermostat to the new and answered all my questions. Everything has been functioning just as I expected for both heat and AC. I recommend Plumbing Tree for these services based on quality and reliability - also cost was competitive and the team they used had the expertise required. Additionally they were easy to work with and I plan to use them again on another project. Thanks Keith and team- I appreciate the quality work!"

Sump Pump Installation FAQs, answered by experts

The life span of a water pump ranges from five to 15 years on average. Regular maintenance can extend its life. If you notice significant drops in performance, strange noises, or frequent malfunctions, consider a water pump or well pump replacement. Always get in touch with a professional if you're concerned about yCan I install a water pump myself?our pump's condition.

DIY is possible for simple repairs. Professional services ensure proper diagnostics and long-term reliability.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Sump pump repairs are typically handled by plumbers or waterproofing specialists who are experienced in handling basement and foundation-related issues. Plumbers can address issues like clogs, electrical problems, and mechanical failures, and waterproofing professionals may be ideal if the sump pump is part of a larger drainage or waterproofing system. 

Some people may also call on a general handyperson for minor sump pump repairs. However, for complex problems, hiring a certified plumber or waterproofing expert ensures the work is done correctly and prevents further issues.

Yes, it’s normal (and beneficial) to have a small amount of water in the bottom of your sump pit. It shows that your system is collecting groundwater, rain, and excess water from around your property—just like it’s supposed to. However, if the sump pit is always full, you might have a leak or a faulty sump pump.
