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.

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!
Seth from TerraFirma came out to my house to inspect my basement, which is starting to show signs of water encroachment. I had no idea what to do. He did a thorough inspection of the interior and exterior of the house, and then we talked. He walked me through several options to address the issue, explaining in a way I could understand, and being very receptive and responsive to my questions. He was very professional and courteous. Seth promptly sent me the quotes for the three options we had for the basement, and made sure to be tidy as he headed out! Even before this, the person who talked with me on the phone to take my info, and later to confirm the visit, was helpful and courteous. It's rare to have a such a positive experience with a contractor (just sayin'), but this was it. I am not sure when we'll be making these changes to my basement, but when we do, it'll be with TerraFirma -- and it'll be with Seth. Everything about this company is green flags!
Seth C. was really helpful this morning. It has been raining so much lately and he was able to walk me through all the issues my daylight basement and garage can have and how TerraFirma fixes them. Really appreciate you--/thanks so much Seth
We couldn’t be more thankful for Terra Firma and our experience with them! We bought our first home recently and our partially finished basement flooded repeatedly over the winter causing a lot of damage, stress and worry. We had a few quotes from other companies who didn’t seem entirely confident it was a fixable problem. From the moment Terra Firma came out to give us a consult they were timely, professional and took the care and time to explain all our options and how each of them could work to fix our problem. The crew worked for 3 days straight to dig through our slab, place in ground piping and set up our sump pump , fixing our flooding problem and they kept us informed the whole way. We felt very confident in their fix and the stress relief alone has been an amazing feeling. On top of that they took complete ownership over talking with the city about permitting issues and ensuring everything was up to code. We can’t recommend them enough! Thank you all!
I did a ton of research on TerraFirma when I decided to pursue getting a seismic retrofit in my basement, and then to clinch it, my Engineer neighbor spoke highly of them as well, stating they are top tier in their field. Jake's Crew came out today to review, and instead of selling me on a $10,000+ price tag, educated me on why they were unable to do the retrofit - my foundation is hollow concrete, their drilling would shatter it, and their alternative wouldn't meet my required needs. Honestly, I'm BLOWN AWAY how awesome Jake's Crew was - honest, direct, helpful, and educated me on my foundation. They even cleaned up under the porch for me, graciously turned my outside water off under the crawl space (thank you!!!). I'm so sad my foundation isn't able to be seismically retrofitted but I'm ridiculously grateful to Jake's crew for being so honest. I highly recommend TerraFirma - I read a ton of reviews on multiple platforms, and when they do make a mistake they fix it and make it right. They are full of integrity, and I'll forever remain impressed and won't stop recommending them to anyone/everyone!
We had a great experience with the Terra Firma team. We needed water mitigation done in our basement, and from the sales team to the install team we felt confident throughout the entire process. We were especially appreciative of Luis, Jorge, and Nick on the installation team, as they not only did great work, but they finished ahead of schedule. They also made sure to communicate with us every day to keep aware of progress, and had very helpful tips for how to take care of the new mitigation system and our basement moving forward. Would highly recommend!
These folks came in and did a great job start to finish. When there were some difficulties they were there with answers and work arounds, always willing to get the job done to their high standards. James was great on the front end, informing me on the Everbrace information to stabilize our foundation, Sammy put all the pieces and dates together and Rocky, Harlan & Dorian did a great job on site. The basement not only looks great now, but I have the peace of mind that the foundation won't give out from under our home. Thank you!
We had a great team and a great experience with Jorge, Juan, Manuel, Luis, Aris, and Cristian. They did a terrific job with a full waterproofing system under our home. They were very respectful of our home and treated us with the utmost respect and care. They left the rooms they worked in cleaner than they found them!
I had a great experience working with Samuel Bryant. Sam arrived on time and communicated clearly ahead of the inspection, coordinating well with both me and my tenant. He performed a thorough inspection of our basement sump pump, took the time to explain everything clearly, and provided detailed recommendations based on our specific situation. What stood out most was how responsive and patient he was with all of my questions. I really appreciated Sam’s excellent service, and I would highly recommend working with him.
I had to get a piling holding up the front of my house and a massive cracked beam in my basement jacked up and leveled. Blake, Antonio, and Roberto did an incredible job. My home is much more secure, my floors are more level, and I am overall incredibly satisfied with the work that was done. The crew was professional, and kiundly answered my questions. Furthermore, my project manager Ashley was very responsive and gave me all the information I needed. This service was well worth the money.
Terra Firma did an excellent job waterproofing our basement. Their team was professional, efficient, and the results speak for themselves. Highly recommend Terra Firma for any basement waterproofing needs! Jonah did an amazing job during the sales consultation providing answers to all questions and for only what we needed. The crew of Rocky and Harley are awesome. They did such an excellent job and made sure to explain everything to me along the way. Thank you! 🙏🏻
Great first experience with TerraFirma. Had a basement support beam replaced. The work and everyone involved were great from start to finish with good communication and professionalism. Highly recommend.

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.

Why should I trust your methods to waterproof basements?

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.
