"Our house is almost 130 years old, so we needed to have some foundation stabilization done. The company was a pleasure to do business with. From our initial consultation and beyond, every contact was courteous and knowledgeable. On the first day of the project, after removing the dirt to see the foundation, it was discovered that the existing foundation was not sufficient to support using the helical piers according to the building inspector. The dirt was all replaced and it was arranged to come back out and give me a quote for a different process using smart jacks. Due to circumstances at my local building department, the new job had to be postponed until a new permit could be obtained. Once that was done I was rescheduled and the job was completed in a day and a half. When the building inspector came to sign off on the permit, he raved at what a great job they had done. I would definitely recommend them to anyone who asked."

"Dave and his crew actually did five projects for us. They replaced and re-framed the wood center post in a two car garage, replaced four rows of old, water damaged siding on the back of the house, replaced several boards of deck flooring, sealed the underside of a large deck and filled and sealed some minor cracks in the foundation. Dave and his crew had to re-engineer the center post. The siding was no longer made so Dave had to work with a manufacturer to fabricate new siding for us. Dave and his crew are very professional, courteous, and extremely talented. The did outstanding work, on-time, and we are totally pleased. I would not hesitate to call them again or recommend them. In fact, our next project will probably be to install a channel drain in front of our garage. When we are ready, Dave will get our first call. Don Hauenstein"

"Before any work could be done, the entire duct system had to be removed. TerraFirma worked seamlessly with my HVAC contractor. There were no issues with the duct system installation after the retrofit and encapsulation."

"I researched 4 companies to fully encapsulate a crawlspace damaged by flooding and rats. I also did a lot of research into possibly doing it myself so i knew what to look for. John's was the most expensive, but they were all in the same general ballpark. I was put off by some of the competitors marking insulation as "extra" and not including in their initial estimate. Insulation is required! John's costs a bit more but you get more too: John's insulated the entire floor with wrapped foam pads, dug a drain trench around the entire perimeter, jacked up every concrete pier to slide vapor barrier underneath the posts, and used proper mechanical fasteners on all of the wall insulation boards. Every nook and cranny was sealed with spray foam. The workers were amazing. They did not cut any corners. They nipped and tucked every tight little spot and never complained or made excuses. They built a plastic clean-tunnel every day and took it down down every afternoon. They did not leave behind trash. My crawlspace is clean enough to literally eat off the floor now. I would recommend John's if you want your job done correctly."

"Chuy helped us with drywall repair and finishing work in our house- like floor transitions. He did a wonderful job! He was super communicative and was even very understanding when I had to push the start date out a week due to my son being sick. I would definitely recommend him without reservation. We are so happy with the work that he did! It looks great and the price was fair."

"Superb. Our two technicians Michael and Christian were very thorough. We had a tricky dryer vent, which they figured out and explained to us. Our skinny townhouse is three stories, so they had to carry equipment up and down stairs, which they did without banging any walls. Superb job all around."

"Our CPVC house piping had a lot of water hammer. After turning on the washing machine, I walked out for a moment, and then when I came back in water was dripping from the ceiling exhaust fan onto the washing machine. We have a two story house and they ran the hot water plumbing from the water heater in the garage through the laundry room ceiling. I removed the exhaust fan and could see water dripping from a tee way back beyond reach. The water hammer from the washer likely caused the fitting to start leaking. I turned the house water supply off and sent a message to Simpson plumbing through Angie's list. A lady from Simpson plumbing contacted me right away the next morning. She was courteous, but was having a hard time understanding what the problem was. Maybe I was giving too much information or something, but when the plumbers arrived later that afternoon they didn't understand what was going on. I ran through what happened again and showed them the wet spot on the ceiling. They had to cut an opening in the ceiling and we turned the water on and confirmed the leak. We moved my washing machine out of their way and they cut out the CPVC tee and replaced it with PEX. The piping was brittle so it took him a couple of attempts to get a straight cut which is why I called them to mess with it. After installing the PEX tee, we were leak free and at my request they provided a reference for the drywall repair. He also advised getting some water hammer arrestors installed on the supply lines to the washing machine to stop the water hammer, which I have since done."

Foundation Drain Installation FAQs, answered by experts

No, homeowners insurance policies do not typically cover sump pump installation. However, some companies may offer incentives in the form of discounts or reduced premiums if homeowners install sump pumps. Insurance companies do this because sump pumps can reduce water damage claims. You may also be able to obtain enhanced water-backup coverage after installing a sump pump.

Yes, many people choose to bury their sump pump discharge pipes. When you leave the pipe visible in your yard, you might trip over it or accidentally damage it with your lawn mower. Plus, from an aesthetic perspective, hiding the discharge line underground looks nicer than leaving it out in the open. Before burying a sump pump pipe, review your local building codes to make sure your installation is compliant.

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

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.

Waterproofing or encapsulating protects against moisture, preventing mold growth and structural damage. These services also enhance energy efficiency and improve air quality by keeping humidity levels in check.
