"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."

"All work was done well and efficiently. Unprompted, Kent noted a kitchen sink drain deficiency during the proposal phase that explained drain problems we had experienced. Proposal pricing was in line with the lowest submittals. Simpson was pleasant to deal with, punctual, and addressed my proposal questions promptly. Simpson Plumbing was a very good choice for my plumbing projects."

Foundation Drain Installation FAQs, answered by experts

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

Installation typically takes 1-2 days, depending on the scope and site preparation.

The difference between an ejector pump and a sump pump lies in their purpose and design—an ejector pump functions to remove liquid gray water and soft solid sewage waste from your home. If you have a laundry room or bathroom in your basement, an ejector pump for your sewage tank prevents sewage from backing up in your washing machine or bathroom’s drains.

A sump pump is designed to remove excess groundwater that may enter your home, either due to flooding or periods of heavy rain.

Costs range from $2,000 to $7,000, depending on system type and excavation requirements.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.
