We can help you too! Foundations First is the NW expert in home foundations, basement and crawl space waterproofing, concrete leveling, and wall stabilization.
"I contacted Foundations First NorthWest and a couple of other contractors when an inspection revealed some foundation settling and crawl space damage. I chose Foundations First to make the repairs because they included more work, and at a lower price, than their competitors. I can't say enough about how professional everyone at Foundations First NorthWest was, from the first meeting with the sales rep to the constant communication with office staff throughout the project. Every step was completed without a hitch -- getting permits, engineering, the repair work and county inspections. The work crews worked quickly and efficiently on both the installation of stabilizing foundation piers, and also on the crawl space repairs. And they left the work areas in a very clean condition. I highly recommend Foundations First!"

Mid Valley Excavation is licensed and bonded for both Commercial and Residential work in the state of Oregon. Based in Sublimity, Oregon since 2012, Mid Valley Excavation provides site preparation and excavation services throughout Marion, Polk, and Linn Counties as well as the greater Willamette Valley region.
"Discussed the problem with my steep gravel driveway and its condition by phone. They were very complete in describing the tasks needed to be done, and when they came out 2 days later, they had exactly the right equipment and thoroughly did exactly what they said they would do, in the time they said it would take. The driveway is now graded smooth and evenly sloped, rolled, and compacted. It is in by far the best shape in the 20 years I have lived here. All at what I consider a fair, competitive price. And the crew that did the job was a pleasure to deal with. A very positive experience all around!"

Thousands of NW homeowners have trusted TerraFirma Foundation Systems to keep their homes safe, dry and stable since 2005. Nearly half of our business comes from referrals or repeat customers. We can help you too! TerraFirma is the NW expert in home foundations, basement and crawl space waterproofing, concrete leveling, and wall stabilization.
"I hired TerraFirma Foundation Systems to level my home, expecting a professional job with clear communication, but the entire experience has been incredibly disappointing and costly. From the start, I hired the company to level the floors in my home, specifically to address a nearly 3-inch dip in my kitchen area, a 13x10 room. Yet after they “completed the job,” I still have a 1.5-inch dip in the center of the kitchen, and a corner of my home/kitchen that sits half an inch higher than it should be (above 0%), creating a full inch rise from the living room to the kitchen. Now they’re saying that leveling the kitchen wasn’t included in the original scope, blaming the remaining dip on my kitchen island and fridge being “too heavy” and lacking proper support—an issue they failed to identify in the initial assessment. To properly address this problem, they’re now asking for an additional $7,500, claiming this work was never part of the original job. This feels like a classic bait-and-switch tactic, and I can’t help but feel taken advantage of. To make matters worse, I discovered that they used an uncalibrated machine during the initial leveling when installing, which raised my house over an inch more than necessary, causing significant damage that wasn’t there before. Partway through the lift, they even asked me to sign a waiver to get my house closer to 0% level, effectively absolving them of any damage caused. The technician stopped mid-lift to show me the damage that was already occurring and warned that more would likely follow if we continued. I agreed to proceed, trusting their assurances and assuming their equipment was properly calibrated. I even pointed out to the technician at the time that it did not look level, and he assured me the machine was correct. Now, they refuse to take any responsibility for the resulting damage, dismissing it as “standard” and providing terms within the contract absolving them—despite them overcorrecting the home. There were also repeated measurement discrepancies, with reports showing one reading and verbal statements/emails suggesting different levels. When I sought clarification, I received vague responses and empty apologies. After all this, and nearly $30,000 invested, my floor remains unleveled. The only resolution TerraFirma Foundation Systems has offered is for me to pay additional money to level the kitchen and to wait for the overcorrected area to “settle naturally”—a process that, according to their technician, could take anywhere from two months to ten years. I hired TerraFirma Foundation Systems to fully level my home, not to leave me with an incomplete job, inconsistent results, and vague promises. If you’re considering foundation work, I strongly recommend looking elsewhere—this company has left me with extensive damage, unexpected costs, and a significant amount of frustration."

"After reading reviews I scheduled a handful of companies to come out and bid our refoofing job. Victor came out, was on time, was one of the few contractors who took time to throughly walk the job (inside the attic to ensure we had plywood as well as checking out the entire roof) and most importantly he didn’t talk down to me or make me feel uneducated when I was asking questions about the job. We had to go back and forth with our HOA group on acceptable options, Victor was accommodating and helped me to narrow down the best option for our budget and to be compliant. The team that showed up to work were consistently on time, they were courteous with our yard and outdoor spaces and they took the time to interact with our four-legged kiddos (which helped so they didn’t bark like crazy every day they were here). We have received many compliments on our roof so far from our neighbors and I gladly pass along Victor’s contact information. **one additional thing I appreciated during the consultation process was that I was given a folder with examples of the TL roofing system as well information on the options. The follow up via email and phone was outstanding and I would not hesitate to utilize them - in fact we appreciated our experience so much that we have hired the painting crew for our exterior painting needs."

Absolutely. You can combine drainage installation with many other kinds of projects, such as building a new home, constructing a major addition, or installing an irrigation system. Since excavation is already underway, combining tasks can save you time and money by minimizing labor and material expenses and ensuring seamless integration of multiple systems.
Make sure your contractor is licensed and insured by checking their credentials. Ask for a detailed written estimate outlining every aspect of your drainage system, including how they plan to address specific problem areas in your yard. You can also ask if they have a warranty for their work. Additionally, review customer feedback to confirm the quality of their work.
It depends on your specific water management needs. A French drain is a passive system that redirects water away from your home without mechanical assistance. A sump pump actively removes water when it reaches a certain level. Often, using both systems together provides the best defense against water intrusion, but a pro can give you specific advice for your home and yard.
