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.

So we had Jorge, Juan, and Brad do an encapsulation of our basement crawl space and they did an amazing job. The area they had to literally crawl around in to complete the work was incredibly tight yet they completed their work without complaint and with style. It looks great! The work these guys had to do was tough, give these men a raise! They earned it!
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
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.
We had questions about our basement and foundation and booked Terra Firma to take a look at it. Our visit with their specialist Walt was very informative and helpful. He had a lot of experience, didn’t try to sell us on any unnecessary services, and gave us good advice.
I waterproofed and put a sump pump in my 1890s basement. There was a trench around the basement floor originally. the stairs leading outside to the basement leaked water into the trench as well as some moisture from the wall. The crew was amazing! They were prompt, very communicative as to what they would be doing to make the basement dry. They worked hard and got the project done on time. I would highly recommend them. I do believe there may be other more economical ways to waterproof, however this was done right!
We had successfully used Terra Firma about 10 years ago, so when we had a water incursion this year in a different part of the house we naturally turned to them again. To address water coming through a wall in our daylight basement, they installed their Water Guard and Vapor Lock products, plus a sump pump system. The result looks solid and neat. Haven’t yet had a chance to test it in a downpour, but I’m very confident that if there’s an issue, TF will make it right. I know that because some of our rickety plumbing got dislodged during this process and started to leak. TF stepped up and sent 2 high-quality plumbers, and they found every issue and fixed them all. The install crew themselves were super-courteous and tidy, and they worked overtime to get the job done timely. Kudos to Antonio Rodriguez, Jacob Rodriguez, Rico Aguilar, and Jonathan Heredia.
Terra Firma was really great to work with from our first meeting to the completion of the project. Hannah was our project designer, Kevin G. was our foreman, and Zach F. and Dorian assisted and all did a great job! Due to the cost of the project, we had to make a number of modifications along the way. And once they completed the demolition, they had to make another modification. However, their communication was great and they finished the project right on time and they did great, high quality work. I would definitely recommend Terra Firma for your basement issues.
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!
Marcus from Terrafirma came out to service the crawlspace waterproofing system arriving right at the scheduled time. He was very friendly, courteous and professional. I highly recommend.
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!
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!
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!

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.
