Air Purifiers

The air in your home can contain pollutants that cause allergies, asthma, and an increased risk of long-term illness. A professional Air Purifier is great for cleaning your air and battling against allergies, smoke, pet dander, mold, viruses, and more.

Aspen Air Purifier

Aspen is a professional-grade air purifier that covers 1,500 square feet using 100% safe purification methods. Other air purifiers use technology that can be harmful or have adverse effects on your health, such as UV lights, ionizers, or ozone generators.

Reduces allergies, asthma, and risk of long-term illness.

Unique 3-Stage Air Filtration Process

Aspen’s three custom-designed filters allow maximum airflow and filtration effectiveness. Each stage of the purification process uses a different filter to remove different pollutants from your air. The rest of the unit is designed around the filters. The filters include:

Allergy Filter: Removes mold, pet dander, pollen, dust mite droppings, asbestos, & more!
Activated Carbon Filter: Removes VOCs, odors, formaldehyde, chemicals, tobacco smoke, & more!
Microparticle HEPA Filter: Removes 99.97% of particles down to 0.1 microns, including smoke, soot, bacteria, smog, viruses, & more!

Efficiency And Safety

Other air purifiers use technology that can be harmful or have adverse effects on your health, such as UV lights, ionizers, or ozone generators. Our unit keeps your health in mind and is safe to use. Aspen Air Purifiers use 100% safe purification methods and are guaranteed not to produce ozone.

TerraFirma takes efficiency seriously, just like your health and safety. Aspen Air Purifiers are built with EC fan technology and use up to 85% less electricity than your traditional AC fan. The efficiency gains are even more pronounced at lower fan speeds, which are used most frequently. An efficient air purifier will save you money on electricity while effectively cleaning your air.

Our unit is safe, easy to use, and includes easy-to-change filters, making it a great option for use anywhere in your home where you want clean air. They cover up to 1,500 square feet. Our Aspen Units also include a 10-year warranty with filter subscription and a 2-year standard warranty.

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 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.

Terrafirma just completed the EverBrace wall system on our basement and we couldn't be happier. The house has stopped shaking when the tenant upstairs does laundry. Rocky, our project foreman was outstanding to work with. His communication was fantastic. The project site was well managed. He was always realistic about the daily impacts we might feel while the project was underway (it can get quite noisy) and he was able to flex the project noise level so it wouldn't impact our upstairs tenant. Sammy, their project coordinator, stayed in communication with me from the moment our contract was signed through the project completion.

The only suggestion we have if you're considering the Everbrace wall system, is that you may need to manage some additional work to prepare for the system. Plumbing electrical and HVAC systems will most likely need to be moved. Factor this in both financially and timewise.

Bailey came out and gave us a quote on some crawlspace waterproofing. He was very knowledgeable, professional, and a pleasure to work with. He was insightful and gave several good recommendations, ultimately putting together a great quote for our work with a couple of different options. I would highly recommend giving these guys a call for your next project.

We reached out to a few local companies before deciding to go with TerraFirma for our basement waterproofing. Their solution was straightforward, well explained and competitively priced.

We had a sump pump installed along with a waterproof membrane and dry track along the walls. Their team found a way to put the sump pump under the stairs so it was accessible but out of the way.

I had a few concerns that I brought to their attention after the project was finished. They went above and beyond to make sure that everything was taken care of. I appreciate that they really stood by their work.

Since the waterproofing was finished we had torrential rain (that previously would have left standing water) and our basement remained bone dry. The peace of mind has definitely been worth it.

I reached out to Terrafirma when I needed to get an understanding as to what was causing an issue in my basement flooring. Sam was extremely professional...

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!

Great work. I had huge foundation issues on a large waterfront project. Terra firma waterproofed my basement and lifted the house on hydolic piers to level it out. They saved my project. Seth was a fantastic project manager and Oscar and Jorge completed the job extremely well. 10/10 would recommend for any foundation issues.

With a water floored basement, we contacted Terra Firma to locate the water source which they did in no time. They explained, in detail, what would be done to fix the problem and went to work. They were respectful of our furnishings covering to protect them from limited dust. They were professional and the project was completed on time. We are very satisfied with the end result, quality of workmanship, and price. We would recommend them for foundation work of any type.

We had a phenomenally difficult issue in a basement. We purchased the home in an estate sale through an attorney so no disclosure was made that the basement flooded with up to 4 feet of water in the winter. Called multiple different foundation system contractors, nobody wanted the job. Terrafirma came out estimated through job and did all the work on time and in budget. Made the renters happy also . I am impressed. Dr. Mary Fitzpatric

From beginning to end, we experienced professional attitude and work ethic.
All the employees we interacted with were pleasant. They finished the job in two days even though they ran into an issue. All work was completed and cleaned up very nicely. We are pleased with the finished product. It is reassuring to know we will NEVER have water intrusion in our basement ever again!

Basement Waterproofing Homeowner Questions

Which vapor barrier is best for weeping walls?

The VaporLoc Elite Wall System is better for weeping walls than other commonly used vapor barriers. The VLE system has double sealed seams, waterproof material (not water-resistant), and is much thicker than vapor barriers available at retail stores.

Basement waterproofing: interior vs exterior – which is better?

Interior waterproofing generally provides the most serviceable, comprehensive, and longest lasting solution.

Will a wet basement pass inspection?

Home inspectors cannot pass or fail a home, but only call out defects and make suggestions to consult a qualified contractor.

How long does basement waterproofing last?

TerraFirma-installed waterproofing systems are expected to last decades with regular care & maintenance. We also warranty our installations, our WaterGuard and DryTrak drainage systems come with a transferrable lifetime warranty. Terms apply, view the details here. We stand by our work and the quality of the systems we install.

Should I consider a vapor barrier if I’m not planning to finish my basement?

Even if you’re not planning on finishing your basement at this time, our wall panels can create a cleaner, brighter appearance while insulating and waterproofing your basement walls.
