Signs your
basement needs waterproofing

Unwanted water or moisture in your basement ruins everything it touches. A home with a wet basement is also one of the biggest red flags to prospective home buyers.


These are some signs that you need to stay alert for:

  • Basement floor cracks and leakage
  • Wet basement walls
  • Musty smells
  • Damp drywall and carpet
  • Rusty appliances or floor vents
  • Cove joint seepage
  • Efflorescence, yellow, orange, or black stains
Leaky Floor

Leaky Floor &
Wall Cracks

Settling can cause your basement floors to crack. Additionally, water can build up outside your foundation resulting in hydrostatic pressure, pushing against foundation walls and forcing leaks into your basement.

When water comes up through the floor or basement walls you need to address it. Installing a perimeter drain system and drainage channel, and sump pump will help direct any water that comes through the cracks and away from your valuables.  

Stains

The white chalky powder on your basement walls, also known as efflorescence, is a common sign of moisture in your basement. Usually accompanied by yellow, orange, and/or black stains, moisture is a problem that if not addressed, can make your foundation walls crack and even cause your basement to present leaks.

Even after waterproofing your basement, concrete walls and floors continually absorb moisture from the soil and release it into the air. A reliable, low-maintenance dehumidifier system will ensure your basement and home will stay dry.

Poor Air Quality

Basement Air Quality

Most indoor air quality issues start in dark, wet areas of the house, like the basement or crawl space. Mold thrives in this kind of environment and will commonly be accompanied by a nasty smell. In addition to mold, excess moisture can lead to wood rot, attracting pests like termites and rodents that further compromise your basement air quality. High humidity levels can also exacerbate allergies and respiratory issues, especially for those with asthma. Addressing basement air quality problems not only improves air quality but also creates a healthier living environment for your family.

After removing any organic materials (mold) and making sure your waterproofing system is working correctly, you should still consider other airborne hazards, such as dust mites and bacteria. These can also affect your basement air quality and potentially endanger your health. Fortunately, you can prevent them with the use of a dehumidifier.

Basements WATERPROOFED,
HOMEOWNERS HAPPY

We take pride in our years of experience making homes dry, safe, and stable. From Ashland to Corvallis, Beaverton to Olympia, our Basement Waterproofing clients have given us great feedback.

Christian and his team were on time, personable as well as professional. The team did a great job repairing the leaks in our basement and keeping us informed of any changes and progress.
The best. Hands down. TerraFirma came out and inspected our leak in the basement and I couldn't be more impressed with the service. We are new homeowners and didn't know anything about how their system actually worked. Travis and his partner (sorry I didn't get your name!) took the time to explain how our system works and answered all of the questions we asked. 10/10 would recommend TerraFirma to anyone. *The leak was unrelated to the system TerraFirma put in, but they stuck around to answer questions anyways*
TerraFirma waterproofed my crawlspace, and I'm very happy with the quality of their work and the responsiveness of everyone I've talked with. Morgan listened to our concerns and brainstormed solutions. Tony (the foreman) was excellent at communicating what was happening with the work that he, Harley, and Sebastian were doing, including when they needed to change the discharge plan. We discussed the options with Joel (the lead supervisor) and made a decision together. Since the new plan involved digging under plants that I cared about, Harley offered to dig them out for me before digging the trench to bury the pipe, and then afterwards helped me put them back into the ground where they had been before. I so appreciate everyone's attention to detail and being accommodating, friendly, and careful with their work. And they cleaned up super well when they were done. I heartily recommend TerraFirma!
We hiredTerraFirma to waterproof and redo our crawlspace. We live on a hill which means the crawlspace is on a hill, I am sure it wasn't the easiest place to navigate to get the work done. Heather was the projects coordinator and kept us informed of every step of the project, which we really appreciated. Fernando, was the foreman, and his work crew Felipe, Jorge D., and Jose H. were exceptional workers. This was a three-day project and they were always punctual, very polite, and worked extremely hard getting the project done. Everyone did an outstanding job, and we would recommend the workers and TerraFirma to anyone. Extremely pleased with the workmanship and the project was done on time. The McIntyre's in Oregon City
Marcus and the Terra Firma team were extremely professional and helped us find a cost-effective solution to our sump pump replacement. I would recommend Terra Firma to anyone who needs help with home waterproofing needs.
I had a positive experience with vapor barrier application to my basement walls, a draining system install that wraps around the basement walls, installation of a sump pump, foundation crack repair, sealing/ vapor barrier install in a crawlspace.
We had some basement flooding in our house and after learning the cause, we started the work of getting quotes and inspections from Foundation specialists. When we called TerraFirma, Bailey was able to make time for our inspection within the week. From the jump, Bailey was very communicative, and set expectations upfront. He asked what was going on, looked at some suspected intrusion points and then let me know he'd carry on with the inspection and would let me know when he was ready for me. No awkward standing around or wondering how long it would take. Bailey was very thorough with his inspection and had an impressive presentation once he'd made a diagnosis. He told me his ideas and then asked me mine and we both felt good about the plan walking away from it. Ultimately our timeline didn't work out and we personally had to go a different direction, but if it did I'm confident we'd be in good hands with Bailey and TerraFirma!
I had a consultation with Riley for some water damage in my basement. He was courteous (took his shoes off before coming in the house), informing and on time. It seems like this team has great communication and I will use them in the future should the need arise! My issue was a smaller drainage problem and door framing issue that needs to be addressed by a different specialty.
Initial inspection was thorough with specifics to solve my basement project. James Taylor and his crew, Tarin and Carlos were fantastic. They arrived on time and worked tirelessly for 2 days to waterproof my basement. James went the extra mile to solve an additional concern I had in my garage. James, Tarin and Carlos were fun to work with. I am looking forward to working with TerraFirma on my stabilization project in March. Thanks also to Brent for addressing all my financing questions. Thank you Sammy for scheduling all the details and making sure I understand it all.
Our basement waterproofing job was completed on schedule the crew was professional and easy to work with. When we have other foundation or concrete work to be done TerraFirma will be our first choice. Jonah was a good coordinator and everything went smoothly,
Reached out to these guys to resolve issues with ground water in the crawl space and vapor barrier replacement. Nothing but professionalism and not pushing to sell to unnecessary additional options during quote process. Had two teams come out to work on my house. Don't remember the first group, but Jorge and his team did an outstanding job. Only gripe I have involve the planning team underestimating the duration of the project when working with clay soil. Told by the system design specialist the project was a two day, but later to be told it was one. Eventually it turned into a two day project as initially discussed with the specialist.
Terra firma Oregon City Completed my basement waterproofing project. I want to give a shout out to Antonio , Kameron, Jesse For doing a very fast and efficient job Completing my waterproofing system.

Basement Waterproofing Homeowner Questions


Should I be concerned about damp spots on my basement carpet? What should I do?

If you have wet carpet in your basement or damp spots on the floor or baseboards, this could be a sign that you have a leaky basement issue. Wet basements create more problems than just wet carpet. Mold or mildew could be growing under the carpet, which fills the air you breathe with musty odors and hazardous mold spores.

The first step in fixing your leaky basement is finding the source of the water intrusion. Save yourself the hassle. One of our basement waterproofing experts will inspect your basement for waterproofing problems and recommend the best solution for your home.

My basement has flooded in the past. What can I do to prevent this?

Basements can flood from a number of areas, including: floor cracks, leaking or burst pipes, leaking windows, hatchway doors, sump pump failure, and water heater failure. Our local experts will help you understand and address the cause of your basement flooding.

How should I handle a wet, leaky basement?

  • Avoid any electrical hazards – Avoid touching any devices or wires
  • If possible, pump out any standing water
  • Dry out and discard any wet non-essential organic materials such as wood
  • Find the cause of leaking and flooding. Our local experts will help you find the causes and provide you with a tailored solution to your basement.

What are footing drains?

Footing drains are installed just outside the foundation of your home’s basement. These are thick pipes with holes designed to let water flow inside. A layer of stones is put on top of the drainpipe to prevent soil backfill from blocking the pipe. However, with time, backfill can seep through the stones and clog the pipe. Improperly maintained footing drains can lead to a leaky basement.
