Testimonials for TerraFirma

At the time of inspection I was in the process of purchasing the home and I wanted to include this the proposal and quote in the repair addendum. I appreciate that Deryl had more than one idea so he could work with what I can afford. I was impressed with the fact that Deryl arrived early to the appointment, was completely prepared and even stayed late. Thank you. Overall I felt comfortable with one of the proposals Deryl drew up and went along with the project. The installation held up to the high bar Deryl set. They were early, prepared and stayed late. TerraFirma really impressed me throughout the entire process.

Currently we are in the process of financing the project. Ryan was the most knowledgeable rep I've ever spoken with. Being in the construction industry, I had a lot of very technical type questions that Ryan was able to answer and give me confidence he knew what he was talking about. Everything went fine. Ryan set great expectations and I understood the entire process and project by the end of our brief meeting. We look forward to working with TerraFirma in the near future.

We are on a massive slope and proper drainage/waterproofing has always been a topic of conversation at HOA meetings. Last year we had a house swept away in a land slide. Since then there has been a lot of construction to prevent this in the future. At the bottom of the hill we were more concerned with drainage and excess water then foundation stability. TerraFirma was brought up at the HOA meeting so we decided to give them a call. They were very responsive and courteous to our project plans. The price was fair. Many of our neighbors had work done by them already so we went with them too. Jason was our service rep. He was knowledgeable and didn't beat around the bush witch we appreciated. He was direct but listened to our needs as a customer. The results were excellent and we are glad to put this preventative disaster system in place before we had a real problem on our hands.

We were skeptical of the process until Chris fully explained the reasons behind the drainage system. We were worried about the concrete integrity but the system seems to be a very good solution to the leaky basement. The work to install the drain is only a portion of this project. Tearing out a finished basement and redoing it will be a much more expensive proposition. Or so we thought. We were able to get all of our basement needs completed with one company and for a reasonable price. We now have more living space, increased the value of our home and have a place to relax in.

I really appreciated the professionalism, friendliness and quality of information provided by Chris. It made me feel completely educated on the process and answered all of my questions thoroughly and completely. TerraFirma also provided good financing options. I was expecting to pay a little less than what was quoted but was very comfortable with the fact the I know my crawl space was going to be completely encapsulated with the highest quality solution on the market today. Everyone I have been in contact with at TerraFirma has been very polite and very well trained. My overall rating for the company and the work that they did is a 9/10.

After months and months of research, TerraFirma won my business for a few main reasons. Their product made me feel most comfortable that I was getting the best bang for my buck. This included the drainage system, wall insulation, new walls and flooring. Deryl was a pleasure to work with. Usually I don't expect niche contractors to be this courteous and honest. I didn't feel like I was being up-sold and the final price of the project was under budget and fair. Drew and his Installation crew was the same way. Deryl and Drew are great assets to your company. Their professionalism was top notch. Everyone arrived on time to the appointments and were ready to get to work as soon as they arrived. A 10/10 overall review in my book.

We were so pleased with Deryl. He was informative and did not treat us (without a clue) like we didn't have a clue! He was very easy to talk to and to answer questions. Thank you! Deryl is emailing us a few different option but we are completely comfortable going with Deryl and TerraFirma. Everything was excellent and we look forward to having our project completed.

I had a few initial objections to the price. Kevin was very good at working with me to make sure I was completely happy with every aspect of the project. Kevin explained very well the benefits and necessity of getting this project completed now. The long term benefits to the quality of my home and the value of my home are well worth the repair costs. I was most comfortable with TerraFirma's plan vs cost than the competition.  Foundation problem are not going to fix themselves, in fact, they only get worse and more expensive. Kevin was very helpful in making sure we were well informed and making the best decision. Kevin is an outstanding representative of your company and am very satisfied working with him and TerraFirma.

Installed Waterguard system around half of basement interior wall and sump pump to drain out and attach to existing gutter rain drains outside. We had the estimate complete over a year before we called back to schedule, and they were happy to hear from us and got us scheduled right away. They were booked over 6 weeks in advance, due to the start of rainy season, but showed up on the exact day they had scheduled us. They completed the work much more quickly than originally estimated (less than one day vs two) so less time off work. Their crew cut concrete to install the Waterguard system but the area was amazingly tidy after they left. Half of our basement is finished. They were working in the unfinished area, so we were worried about dust getting around but they kept the door closed, worked very efficiently through the windows in the unfinished area, and took care of business. Since then, we have no longer had water problem during heavy rains.

Overall we were very pleased with the outcome working with TerraFirma and we love how our crawl space turned out. Ryan, our rep, was very polite and knowledgeable. We felt that the plan he put together for our crawl space would comply to our needs as well as our budget. If you are looking for quality work at a fair price, call TerraFirma!

Very impressed with material I was provided with (COMPREHENSIVE BROCHURE) prior to the home visit. Josh was very professional and efficient. We had the same success working with the installation crew. French drains were installed with perfection and precision. They tore up where they needed to install the drain but cleaned up very well. It looked the same as before, with now, a drain installed. We were impressed by the whole production and recommend the services.

I'm very impressed by the overall organization and production of TerraFirma. The call center handled my call with courtesy and efficiency first diagnosing the problem and making sure we were calling the right people to not waste either of our time. Josh was on time to our appointment and prepared to perform an entire inspection. We also appreciate that we received a price estimate at the time of inspection. The price was fair and the service we felt was going to effectively prevent the basement from flooding in any rainy conditions. Josh was very personable and presented himself well. He is a great representation of your company and the overall professionalism of the team. I will be recommending your services to friends and neighbors because I know they will be treated in the same positive manner as I was.
