"Chris was very thorough and went above and beyond which is why we chose Crawl Space Jam for our project. We needed full crawl space encapsulation with a dehumidifier due to moisture and mold issues. Other companies recommended installing perimeter drainage and a sump pump in addition to encapsulation. Chris did the extra work to uncover an existing perimeter drain in our crawl space and he even tested it to ensure it was draining properly. I recommend Crawl Space Jam without hesitation."

"Thermo Direct came to our rescue! Since we moved to the Apex area we have been nursing an old previously neglected HVAC unit until it recently quit working. Because I suffer from chronic asthma it’s crucial that the HVAC system is working. Eddie Blanchard listened to our concerns and helped tailor the best system for our needs. The super friendly office staff organized the installation date and time and then a courteous and efficient installation team removed the old unit and replaced it with an amazing, state of the art system. With the final touches completed yesterday by Lucas and Doug. My wife and I appreciate how we have been treated by Thermo Direct and plan on being a part of the Thermo Direct family for a long time! We strongly recommend!"

"Main lead tech, Ron, did well hooking coil to outside compressor. The asst tech went under house to install new cooling coil to ductwork. He bent ductwork, taped it with insulation tape that connects coil to duct work. He failed to tell main tech what he did, but also main tech failed to check asst tech's work under house. The unit was working when they left. But they only ran it lil bit. Because it was a cool week we did not need to run a/c.. When temp rose, we turned on a/c. Worked for about 2 hours, when air pressure eventually blew insulation tape apart which allowed all the air to go under house. In turn, it froze up cooling coil & compressor. After calling, texting, etc for 3+ days, with no answer or response, we had to call another company to come because we had no a/c. The new company told us what had happened & gave us estimate. We said go ahead because we had no a/c. He went under house, removed bent ductwork with tape still on, & brought to us to see. He replaced the ductwork, & attached ductwork to cooling coil. He ran a system check with professional tools which is how he determined the previous tech added too much freon. So the additional cost for 2nd a/c company was $350. In addition to the already $800 we already paid Bellcow."

FAQs for sump pump or interior foundation drains installation projects in Raleigh, NC

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.
