"Had blue umbrella do a French drain and three new sump pumps in basement. Excellent work with high quality materials. Worked with Tony who was extremely professional and nice. The owner Steve also came by the site to check on progress and whether I had any questions. He also followed up after which was great. Wilson the foreman was really helpful during the process. Also, had quotes from several other vendors and Blue Umbrella was the most competitive. High quality work with professional team. Highly recommend."

"Alec was professional and explained what needed to be done to clear the lavatory drain with an electric snake. He installed new angle stop for lavatory. He supplied and installed two supply lines for the faucet. The old valves were rusty and did not work like they used to. Alec said the old valves could leak in the future, and we did not want that to happen. They arrived on time and continued working until the job was complete."

"I had a wall in my basement that was filing up with water from runoff outside. The wall started leaking into my basement. The crew jackhammered a trench along the wall in my basement and installed a drainage pipe, fill and a sump pump. They cemented over the trench and it looks like they were never here. Lots of rain since then and my basement is dry. Timely and professional- highly recommend"

"From the estimate process until final product finished today, we could not be happier with BQ Initially was quoted a 2 day process to complete our Aquastop waterproofing system and sump pump replacement, Steve, Curtis, Pedro, and Josh arrived as promised at 7:30 and completed the job by 1:30. They explained the entire process and updated us throughout. They were very professional, efficient, and polite. Everything was explained about the new system and cleanup has the basement back to pre construction condition. We highly recommend BQ Basements and Concrete!"

"This type of work should be on â dirty jobsâ . These guys worked all day in a pretty awful NJ winter day but kept things as clean as possible, replaced 2 existing sumps with their triple sump and a supersump. Very happy with the install and peace of mind with the battery back up included in the triple sump."

"They came out on a weekend and we're our saving grace during one of the most frustrating experiences we've had in this house. We couldn't use any plumbing without flooding the basement with sewage, it was early stay at home days, and we felt like we would go mad. They showed up and gave us an price for replacing the broken pipe, and set in to work. They worked for the entire weekend essentially, staying extremely late at night and showing up early the next morning, and at one point driving far out at night to get supplies since their usual local place was closed (again, quarantine time) . The reason it took so long was because after opening up the floor to get to the end of the pipe to replace it they found more damaged pipes, and replaced those as well. By the end of it they had spent the entire weekend on a job they expected to only last an afternoon, had charged us not nearly enough for the amount of work they did, and fixed a leaking bidet we had for free for good measure. They also advised us to do camera scan to look for any other problems, which they couldn't do until the water drained out, and even did an initial mop of the basement (which, remember, sewage flooding). I'm honestly half convinced these people are magic helpful brownies or something, it's unreal how helpful they were! Somehow our drier which has not succeeded in drying clothes for over a year has started working in a single cycle since they left, despite the fact they didn't even do anything with it, and in fact specifically said they don't do driers and offered to recommend someone else when we mentioned it. Suffice to say, I cannot recommend them highly enough"

"The service from Alliance Service Pros was fantastic! Tom Kensinger was my service pro and he delivered above and beyond my expectations. The flower bed in front of my house next to the foudation was very soggy and water was coming through the foundation into my house; assumed a water or sewer leak. Chalres from Alliance pros investigated the situation, throughouly examined the situation, checked all township/state codes and then provided a compeitive quote. Two days later Tom was onsite for the repair, it was around 90-95 degrees. He hand dug 6 ft of earth to uncover a broken water line in the foundation. Tom overcame serveral challenges with main water line shutoff not working, significant flooding while digging to get the job down. He also brought a change of clothes, before coming into the house to not muddy up my house/basement. He repaired the waterline outside and through the house and then sealed the water line and the sewer line in the foundation in and out. He took care on digging to separate the mulch and dirt, so upon refilling the hole he could leave it as he left. Lastly, he hosed down all areas of my porch, driveway and sidewalk. Basically looked liked it was never touched. He worked 12 hours and promised to not leave until we had water that night. I have never seen this dedication from a trade professional before and my long review is a return in kind for the level of work he showed my family. They will be my go to plumbing professionals from now on."

FAQs for sump pump or interior foundation drains installation projects in Princeton, NJ

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.
