At Ram Jack West, we treat customers with respect and care. If you notice cracks, damages, or other issues with your foundation, our team is ready to help. We have innovative systems that have been refined over our 40+ years of experience.

"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."

We build our team on "Honesty, Ethics, and Morals". Let us show you the Classic Remodeling NW Inc. difference!

"I am a repeat customer, so I knew the carpenter, Joe, coming in. I started by using their design contractor. I gave her the colors and ideas (beach theme, ceramic wood-look floor tiles), and she pulled the rest together. Invaluable because I can't trust my own taste. They removed a square shower in the corner and a set of shelves next to it, and glassed in that end of the room for a full shower. We put tile down along the whole room, with a recessed shower pan, and a linear drain against the wall. Joe built-in medicine cabinets, and trim all around the room, per my design pictures. The subs included a glass door guy, the plumber, the tiler, painter, and the countertop slab tiler. We also had some work done in our hallway. They removed the single boob light from the middle, and installed two recessed lights on either end, along with putting two switch boxes on either end of the hallway. Joe built a floor to ceiling cabinet in a 13” dead space at the end of the hallway, which included a laundry hamper on tracks, cubbies, and shelves. And then on a whim, I asked to have our old hallway linen cupboard doors replaced to match the new ones. We had two leaks during and after, but one reason I would use them again, is how they handled both times. One was a leak from the plug on the toilet supply. We found it on a Saturday morning, and I ended up waking up our carpenter with my text. He came out and figured it out and fixed it by 1. The other one was after everything was done and cleaned up, and we had paid for everything. The basement bathroom ceiling, fan, and wall below the master was wet one day, and we realized a joint in the pipe from the master toilet to the stack was slowly dripping between the two rooms. I texted Joe again, and he referred me to our GC, who came out with a plumber and fixed it. They had to make a hole in the downstairs drywall, so he has been coming back regularly to put three layers of mud on the new drywall. I was so sure that they would regretfully find that it wasn't their fault and we would have to deal with the cost and bother of finding a plumber and carpenter. Start to finish, it took about four months, but three weeks of that was the initial tile order, and another three for an incorrect tile order."

Basement Leak Repair questions, answered by experts

In some cases, operating a snake can damage your drain and pipes. This depends on the overall condition of your pipes and how gently you operate the auger. For instance, older galvanized pipes covered in zinc are susceptible to scratches when using a drain snake. Additionally, it’s common for newbies to apply too much force when extending the snake, leading to scratches and related damage. You can also crack the porcelain with an electric auger if you’re snaking a toilet drain. If you’re using a manual snake or auger, the risk is minimal.

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

When considering finishing your basement, take into account a few pros and cons:

Pros

  • Can increase the value of your home

  • Separate space from the rest of the house 

  • Customize and personalize the basement to suit your needs and style

  • Increase the amount of living space in your home

Cons

  • May not regain enough value to cover the cost of finishing

  • Lack of natural light if it’s below ground level

  • Moisture or flooding can cause costly damage

  • Installing plumbing and electrical can be messy and costly
