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

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.

I have used Terra Firma on 4 (soon to be 5) projects over the last few years. They offer a variety of services relative to foundation issues, drive and walk ways and basement issues. They do great work (as recently evidenced by Mike McCarthy and his installation crew on my sport court and driveway) and they have a great warranty, both of which justify their cost. I have a couple of other projects in mind and won't hesitate to call them for one of their free estimates and to discuss options as they have done in the past. Highly recommend for peace of mind.
I had a difficult project to install an egress window in my finished basement. Great communication from the team and positive attitude from the crew (despite significant challenges!) from initial estimate through completion. Terrific work. Would highly recommend Terra Firma.
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.
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.
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.
I purchased two waterproofing systems from them a few years back. After the rain the past couple days its time to leave a glowing review. They did an interior drain in my basement and a separate drain tile system in my crawlspace. Both systems have been working flawlessly for 3 or 4 years now with zero water intrusion into my basement that I totally renovated after their install. They've also come out every year as promised for servicing. Thankful for connecting with them. After hearing the river of water enter into the pump and it go off every minute or so for nearly 12 hours yesterday, they deserve 5 stars. I would recommend them to anyone.
The guys doing the work were always right on time, they were very professional from the beginning to The end of the job...they were very polite and clean. We are happy we called TerraFirma foundation systems. We feel much better about the future rains this winter, knowing our basement is taken care of and we have a reliable pump system. Amber was very helpful and answered all our questions...
TerraFirma just did an outstanding job for 3 days replacing 6 post and piers with wood rot with stronger metal posts and installing a metal support wall. The crew led by Brian was very helpful explaining the work and answering all of my many questions. Both Brian and Michael kept the basement space clean and orderly after each day of work and after completion of job. I would definitely recommend them and would hire them again if needed. My experience from the original sales/contract meeting with Ryan to the final completion of the job was positive and thorough. Good Work all!
One more review for these guys… Roberto returned to finish up a few things and as before, he was professional, conscientious, efficient, and left the place immaculate. Love our basement - thank you so much!
The technician (Clay Carter) was very professional, honest, and helpful in explaining parts of the system I had kinda forgotten about. I'd somewhat neglected my basement system over the years, so I appreciated his kindness and patience as he went through and checked everything. System is still working great though! No water in the basement after 5 years, and the mechanical stuff was still in good order, I'd call that a win.
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.
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!

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.
