POOR AIR QUALITY

Humidity and condensation in a crawl space are a recipe for disaster. Excess moisture leads to mold growth, wood rot, and foul odors, causing issues for your home’s health, air quality, and value.

After removing any organic materials, making sure your waterproofing system is working correctly, and installing vent covers, you should still consider other airborne hazards that, fortunately, can be prevented with the use of a dehumidifier.

Encapsulation and consistent maintenance don’t just protect against crawl space moisture problems—they also retain a stable temperature in this area, improving indoor air quality and reducing allergens. Over time, this can prevent costly repairs caused by worsening structural problems or degradation. Additionally, a well-encapsulated crawl space boosts your home’s resale value; ultimately, it is a wise investment for homeowners intending to stay or sell. So have Terra Firma fix your crawl space problems today to start reaping the benefits.

Kudos to Riley, a TerraFirma System Design Specialist. Riley is a smart guy. Honest and communicative. He's focused on problem-solving instead of just selling products. You don't find that skill very often these days. I had an excellent experience getting a crawlspace encapsulation estimate from him.
Andrew, Joey, Caidin, and Preston did the encapsulation of our crawl space. A dingy and damp crawl space has been transformed into the look of a hospital operating room! All were good workers and very helpful, with ideas and tips, and noticed issues that were not a part of their duties, but nonetheless did need to be addressed. No review yet on how the system works, but I can highly recommend this installation crew! Thank you guys!
We had mold issues under our house. TF was chosen to encapsulate the crawlspace, remove insulation and put in a dehumidifier. The job was difficult due to more dirt removal required than anticipated. The field team was excellent. They worked extremely hard, were neat and very friendly. They did a terrific job in a difficult situation. TF gave us a date for the work and arrived as planned and stayed on the job until completed. They dealt with us honestly and with integrity. Very satisfied with the solution, the results and the process of working with TF.
Just had clean out of old duct work and old insulation, etc. plus encapsulation of my crawl space. The crew worked really hard and professionally throughout the 5 day process and the foreman kept me informed along the wife. Have worked with Terra Firma on several occasions: pier placement and jacks for house, french drain in crawl space, and replacement of sump pump, etc - alll involved from the estimators, the office personnel, and work crews have
been excellent throughout.
We called TerraFirma with a pretty significant problem. We had just purchased a home and were a bit misled on a couple of items. The basement and crawlspace were mold infested (which we did know). What we did not know was that at times of the year, there would be some standing water in the crawlspace. We also didn't know that the drain from the sump pump was actually underwater (adjacent lake), nor did we know the pool backflushed into that same line and actually would enter the crawlspace whenever that process occured. The crawlspace was unvented and unconditioned....the perfect storm of BAD! Our goal was to first remediate the mold and then resolve the issues that allowed the mold to grow in the first place. Enter Terra Firma. Tulane and Terra Firma stood head and shoulders above every other company I spoke with. It wasn't jus that they were going to fix it- we literally walked through every step and every product-I knew what I was buying before we started. The crew was professional, on time and did exactly what they said they would do and in the time frame promised. With Terra Firma, we waterproofed and encapsulated our crawlspace, we insulated the crawlspace, we installed new sub floor drainage with new sump pumps with battery backup to lower the water table under the house (that now drains above the high water line), we installed new structural floor posts where others had rotted, we installed a bypass for the pool overflow and we installed dehumidification and we are in the process of now conditioning the space. Terra Firma led the way and did an excellent job both on the communication and on the installation (at the price originally quoted!). I would highly recommend this firm for anyone with complex and challenging crawlspace issues. Great work and fantastic team from start to finish!

These folks are WORTH the call and having them out! Seth, specifically, was amazing at scope, plan and presentation. He was so knowledge and really took into account all of the needs of the house structurally and visually. He was extremely professional in house and on the phone. Nothing was over sold or up sold, and every concern I had was listened to and taken into account. Every detail was in the bid neatly and nothing was out of place. If you've got a basement or crawlspace project, this is as professional as it gets. I will DEFINITELY be keeping this company in mind for future projects and for friends and family. Call. Ask for Seth. He's got you.
