"Purchased a 1906 home in North Portland with an uneven foundation that had been patched for 60 years, but needed serious stabilization work. I contacted multiple foundation contractors in the greater-Portland area and Ram Jack was the only team that provided a full worse-case estimate that included everything that I may need to permanently stabilize the home's foundation. Other contractors' estimates were higher, omitted some of the features of Ram Jack's estimate, and involved greater excavation work around the home. While I was collecting estimates, I had multiple contractors check the levels on the house and could see the home was continuing to sink as much as half and inch in some areas within only a few months, so I knew I had to do something soon as the hotter summers are causing significant erosion to the clay soil in north portland. After paying the 50% down payment, I was quickly in touch with multiple project managers and structural engineers who were able to answer my questions as the work plan developed. I work from home and have two cats, so I was a bit worried about the noise and needing to leave at certain times during the work. Ramjack devised a plan of installing 12 helical piers from the basement and 2 outside for a small crawl space area as well as replacing most of the piers in the basement that had water damage. During the excavation and pier installation, I didn't have to leave my house at all, my cats were fine, none of the utilities ever needed to be turned off and none of the neighbors said they heard more than the hum of the generator outside; insane professionalism. The work team kept me informed at every step of the excavation and pier installation and was able to recover an inch of lift with only a few drywall cracks that I patched in a day. I could have gone further, but wanted to avoid any potential damage to the sewer pipes and stay within my budget. During the lifting, I was standing with the lead construction manager who kept me informed of every risk as we lifted the house bit by bit. During the excavation my basement looked insane with mounds of dirt everywhere, but the construction team cleaned everything flawlessly; all I had to do was a quick mop and the basement was good as new again. Overall had a great experience with RamJack; the 20 years in business shows, most everyone I dealt with had been working with them for years; the construction manager had been doing pier installation for 15 years. The work was expensive, but cheaper than the other local contractors, and certainly way cheaper than replacing the entire basement foundation. Ramjack was even able to take a few grand off the intitial worse-case estimate for solutions not needed. Glad I was able to repair my 120 year old home; here's to another 100 years. Big thanks to Pancho and Stephen, as well as the structural engineers and project managers; I'm very happy with the work."

French drains can last between 30 and 40 years, offering long-term protection for your home's foundation. They work by diverting both underground and surface water away from your property, helping prevent water buildup and structural damage. Opting for models with cloth filters can extend the drain's durability even further. Regular maintenance and professional installation ensure your system works efficiently for decades.
You can install a French drain anywhere from two feet below ground to the level of your foundation's footings. If you're dealing with surface water like rain or snowmelt, a shallow drain might suffice. But if you're concerned about groundwater, you'll need a deeper drain inside your home. Contractors typically install interior perimeter drains beneath the basement floor's concrete.
Yes, interior French drains are very effective at preventing flooding and water damage in your home. When properly installed, they channel moisture away from your structure. If the perimeter pipe ever clogs, a plumber can easily access it for repairs. To maximize efficiency, it's essential to combine an interior French drain with a sump pump, which helps redirect water away from your home.
Certified professionals install French drains to ensure they work properly. You can hire foundation specialists, licensed plumbers, or experienced landscapers—all have the expertise and tools needed for proper installation. They design systems that redirect water safely away from your property. By trusting a qualified expert, you ensure your French drain will perform well and protect your home for the long term.
After installing a French drain, you should take a few steps to keep it working well. First, repair any areas of your lawn or garden that were disturbed during installation—this might include reseeding grass or replanting flowers. If you had the drain installed in your basement, consider upgrading your waterproofing for extra protection. Finally, schedule regular inspections and maintenance to ensure the system continues diverting water efficiently and protecting your property over time.
