Leaking in basements and crawl spaces in Seattle and Renton, WA

One of the primary concerns associated with rain in Seattle and
Renton is water leaking into homes. Rainwater can seep through
roofs, windows, and foundations, leading to leaks, moisture damage,
and mold growth if not properly addressed. Homes with older or
poorly maintained drainage systems may be particularly susceptible
to leaks during heavy rainfall.
Seattle’s hilly terrain can exacerbate drainage issues, leading to
pooling water around homes and potential leaking in basements
or crawl spaces.

Foundation and terrain challenges in Bellevue,
Kirkland and Auburn

One challenge posed by Bellevue, Kirkland and Seattle’s hills is
the potential for soil movement and instability. Gravity,
combined with the weight of the building and the presence of
water can result in wall and floor cracks. Stay alert for the
most common signs of foundation problems in your home.

Throughout the greater Seattle area, including Renton, Bellevue, Kirkland, Auburn, and beyond, our work speaks for itself

had leveling and damp under home issues. They completed work and are always quick to answers all concerns or questions. Thank you Terra Firma staff
Seth was knowledgeable, very experienced and the price was extremely reasonable. I had plenty of options to choose from. I also met with the competition and it felt like they were recruiting high schoolers to do their estimates.
Had a great experience with Terra firma Mark Spandler was the tech I worked with he explained all the details on the foundation of my home he was very helpful. . I would highly recommend him for service.
Thank you Seth, for being so thorough during the inspection of our needs. Your explanation of what caused our problem and the process to fix it was easy to understand. We are looking forward to having our foundation issues repaired by Terrafirma.
Best customer service in the northwest !
Jake and his crew did a terrific job fixing the cracks in our foundation at a reasonable price. We would definitely use them again!
The guys did a good job at fixing the problem with my foundation and they luckily even got me in earlier than scheduled. They are more expensive though and left a mess as far as dirt/mud all over the sidewalk. The 'inspection' guy who first came out to give me an estimate stated that it would include putting the pavers back and cleanup. I had to ask them to do that as they were leaving without doing so. They did put the pavers back, but no cleanup. They gave a 25 year warrantee on workmanship and 75 year warrantee on the products used.
We had two companies come and provide evaluations of our foundation repair needs. TerraFirma was by far the most professional and responsive company. In the end we did not go with the lowest bid but we did go with the company that provided the most professional response and gave use the most confidence it would be done right. We were not disappointed 🙂
Seth from Terraferma came to my house on time gave me a fair estimate and recommendations. There was no pressure. He was courteous and I have no hesitation in recommending Seth and his company Terrafirma for any future work.
I recently purchased a home that I knew had water encroachment in the basement. Terra Firma came and presented what can be done and I knew it had to be done. Tieran and his crew came in and did exactly what was explained to me. They answered all my questions and I feel very confident it will be a dry basement going forward. I highly recommend this company for any work that needs to be done to foundation, water issues, crawl space etc. Fantastic company!
