"Removed old water heater and installed new water heater and brought water heater up to code. They arrived on time and performed the work efficiently and neatly. The price for the direct vent water heater plus installation was about $250 less than another local quote. Overall I am very satisfied with the price and quality of the installation."

"I have nothing negative to say about the whole process from the initial inspection to the completion of the project. Their quoted price for the project was not the highest or the lowest I had received, but I selected Mount Valley because I never felt pressured to agree to a discounted price valid only for a short period of time, and the solution that they proposed to take care of my crawl space made the most sense to me. The installation crew was efficient and cleaned up any debris. You might found a cheaper company, but pay attention to the specification of the material used and the overall proposed solution. For such a project I got three quotes, and found very comfortable working with Mount Valley Foundation from start to finish."

Septic Repairs
Holy cow!! We found it!
Almost looks like we didn't just install 400' of 4'' Storm Drainage to save the septic system from near total failure.

Sometimes excessive storm water can wreak havoc on a septic system and cause the system to break down prematurely. 
The septic system was drowning, we suggested diverting the storm water to protect the septic tank & field lines. Problem Solved.

"When our old tankless water heater gave out, we knew we needed to get it replaced quickly—and we’re so glad we called Chisholm. They made the whole process super easy. The crew showed up right on time, were friendly and respectful, and clearly knew what they were doing. They got the new tankless water heater installed, and they didn’t leave a mess behind (huge bonus in my book). They even stuck around to make sure we understood how everything worked before they left—no rushed job here. The new water heater has been running like a dream—hot water on demand, no weird noises, and no more surprise cold showers. Total game changer. If you’re on the fence about who to hire, just go with Chisholm. They’re the kind of company that does things right and treats you well while they do it."

FAQs for sump pump or interior foundation drains installation projects in Duncan, SC

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.
