Maintenance
& Service

Mark Johansen was very thorough in inspecting our sump pump, VaporLoc and performing a general inspection of our crawl space, providing pictures of every concern. He then made repairs to all of the areas discovered and went above and beyond in service!

Work well done and coordinated with HVAC company. Started and ended as promised. Courteous workers who explained what they were doing. Only glitch was that when boring through concrete foundation for sump pump drain, the comcast cable was damaged.

Today, Marcus, from Terra Firma arrived to do annual service and maintenance on our sump pumps. He was very professional and also friendly. He's the first to show me videos of what is actually in the crawl space and the work he had done, and also explain the need for a new battery with next year's maintenance, which I appreciated. He unexpectedly had to do work above and beyond when my 80 pound Lab/Shepherd mix suddenly jumped into the crawl space, by helping retrieve her. Thank you, Marcus--everything well done.

DJ from Roseburg came to do an Annual Maintenance on humidifier and sump pump. He also inspected the encapsulation TerraFirma installed after flooding 7 years ago. He replaced battery, cleaned up and let me know we were on year 7 of a 10 of our annual inspection we had purchased at installation. Glad we chose that option as that has saved us money. DJ was on time, knowledgeable, professional and had a smile when he arrived and when he completed the job.

I love TerraFirma. We had a new foundation with a sump pump and dehumidifier four years ago. First, it is so great having a dry basement! Each year, TerraFirma sends someone to check the sump pump and the dehumidifier. Jeff did the inspection last year and this year. He showed me what he was doing, documented with pictures, answered my questions and showed up on time! This has been my experience with every interaction I have had from the beginning of the project to the follow-up. Here is a picture of the new foundational wall and my workout area.

Edit: Jan ‘26 Unfortunately this sump pump did not solve the problem after all, as water again came in after several days of hard rain. To be fair, TF did not guarantee a solution. I still think it is a good company but sadly my problem persists. Previous review from Nov 25 - Terra Firma installed a sump pump in my home that has solved my water incursion issues. This had been a problem for months. I had several different companies and professionals out to evaluate and try to solve the problem, from plumbers to leak detection companies and a few more. Most scratched their heads and said "this is a mystery." Terra Firma came up with this solution and it is working. I wanted to wait until we had significant rain to write this review - and after the past few days of pretty good rain, and no water coming in - I feel confident that the problem was solved. They were helpful, considerate and creative. They didn't try to sell me more than was needed. I recommend Terra Firma.

When we first bought our 1900s fixer upper, we had no idea what lurked behind the walls of the illegal basement apartment. Once we opened up the space we were in for quite the surprise. All the wooden post holding up the main beam of the house were rotted through at the base. You could stick a pencil through the old, soft wood. Working with TerraFirma to fix the issue was an easy choice. Eric came out to assess our problem. He was friendly and professional as he walked me through the process that was needed to fix our foundation. It wasn't going to be cheap. Don't expect this kind of work to be inexpensive (especially on older homes). We needed concrete to be cut, 2ft cubic footers poured, and six shiny new steel posts. (And while they were coming out anyway, we had them do seismic retrofitting too). There's all kinds of math and engineering that goes into determining what's needed to structurally support a home. TerraFirma handles it all. And they are experienced enough to know what it's going to cost. One of the best parts of working with them (besides the friendly employees and professional workers) is that the price they quote you is going to be the price. Full stop. There are no unexpected add ons at the end. I can sleep well at night knowing TerraFirma's work is holding up our home. A few months later when the rains started in earnest and our basement flooded (an issue we guessed had been going on for a while, hidden by those illegal apartment walls and leading to the rotting of the old wood posts) we knew who to call. Eric came out again to look at options for a sump pump system and even worked on adjusting those plans (while he was on winter vacation with his family!!) when we discovered that a third wall was seeping water and we needed a much larger amount of fixing than originally thought. We no longer have to worry during downpours. While our old fixer upper still needs a lot of work and love, we know that we are (literally) starting from a strong, solid foundation thanks to TerraFirma.

The technician (Clay Carter) was very professional, honest, and helpful in explaining parts of the system I had kinda forgotten about. I'd somewhat neglected my basement system over the years, so I appreciated his kindness and patience as he went through and checked everything. System is still working great though! No water in the basement after 5 years, and the mechanical stuff was still in good order, I'd call that a win.

My pest inspector found a lot of water in my crawl space after a routine inspection. A plumber found no leaks and believed it to be ground water. TerraFirma responded to my needs promptly and ended up digging a ditch around the inside perimeter of my crawl space, inserted pipe and covered with river rock for drainage. A sump pump was installed inside to drain outside. They took such care with the drain they dug outside that when they were finished you could hardly tell where they had dug the ditch. They took such care to protect my home - especially since the crawl space access was inside my home. They protected my floors and walls very carefully and completely - even with having to bring in numerous wheelbarrows of rock. They also cleaned up both inside and outside my home so you couldn't tell anyone had worked all day to completed this large job. They did an amazing job!!! Thank you TerraFirma for your great work ethic and service.

I used Terrafirma for foundation support repair. I found the staff and work crew very honest and extremely thorough! Was a little outside my budget, but I was so happy that I chose them! Satisfaction in every area is so worth it!! Will choose them over and over and refer! AE
