We had a large renovation project at our home, and we couldn’t be happier with the results. The team replaced almost all of our windows, painted the entire house and garage, completely remodeled two bathrooms, removed a wall to combine two rooms into one, and created beautiful smooth walls with molding in the new space. They also installed new carpeting throughout the house, added ceiling lighting to almost every room, replaced all of the outlets and switches, and took care of many other smaller projects along the way. There was a lot of work involved, but the team was hardworking, responsive, and always willing to help. Communication was great throughout the entire process. We especially appreciated Nikolai, the project manager, who was very attentive and easy to work with. We are very happy with the quality of the work and would definitely recommend this company. If we have any future renovation projects, we will absolutely reach out to them again!

I’ve had the opportunity to work with Tenax Construction on multiple projects as the engineer of record, and my experience with their team has been excellent. They consistently provide thorough and detailed information regarding each project’s specific requirements and are highly responsive throughout the design and coordination process. Their team goes above and beyond to support well coordinated solutions and successful project outcomes. Their approach to design and construction is practical and focused on efficient execution in the field, with a consistent standard of quality across conventional residential and high performance, high end construction. Tenax Construction has consistently exceeded my expectations throughout our work together, and I highly recommend their team.

We recently completed a bathroom remodel with Tenax Construction and the entire experience exceeded our expectations from start to finish. Daniel, our sales consultant, was knowledgeable, professional, and took the time to understand exactly what we wanted. He provided clear information, answered all of our questions, and made us feel confident in moving forward with the project. Elizabeth , the designer, was absolutely fantastic. She listened carefully to our ideas and transformed them into a beautiful, functional design that perfectly matched our style. Her attention to detail and creative vision made all the difference, and we couldn't be happier with the final look of our new bathroom. Nikita, our project manager, kept everything running smoothly throughout the remodel. He maintained excellent communication, ensured the work stayed on schedule, and addressed any concerns promptly. His professionalism and commitment to quality gave us peace of mind throughout the entire process. The craftsmanship was outstanding, the team was respectful and professional, and the project was completed with great attention to detail. Our new bathroom is beautiful, functional, and built to a very high standard. We highly recommend this company to anyone considering a remodel. Thank you to Daniel, Elizabeth, Nikita and the entire team for delivering such an exceptional experience and a stunning finished product!

Tenax is a very good construction company to work with. Dennis was great thru the entire process. He’s hands on with his workers and also the homeowners making sure everything is going as it shud. He’s always available when u reach out to him and personally handles any issue that may arise. I had stucco wrk, whole house paint, doors removed and replaced. Everyone who came out was awesome. I am so pleased with the work and the customer service I am booking another appointment to have more work done on my foundation and insulation. I most definitely recommend Tenax Construction. Dennis will make sure u are provided with excellent work and the best customer service. He makes sure the customers are happy and pleased with their work & that’s important! Thank you Dennis and all the crew!!

I had a great experience with Tenax Construction. They did an excellent job repainting the entire space and replacing the carpet, all within just a week—which is honestly impressive. A special thanks to Vitalii, Philip, and the entire crew. They were extremely responsive, paid attention to every detail, and made sure all my requests were handled properly. The coordination and customer service throughout the process were top-notch. If you’re looking for a team that delivers quality work quickly without cutting corners, I’d definitely recommend them.

ICF Construction FAQs

What are Insulated Concrete Forms (ICF)?

ICF uses interlocking foam forms that are stacked and filled with reinforced concrete. The result is a solid concrete wall with continuous insulation on both sides, providing superior strength, energy efficiency, and durability.

A typical ICF custom home takes 12-18 months from design to completion. ICF construction is actually 2-4 months faster than traditional building methods due to the efficient wall system.

ICF homes typically cost 5-10% more upfront than conventional construction. However, the 25-50% energy savings, minimal maintenance, and 75-100 year lifespan make them more cost-effective over time.

Tenax Construction has built over 20 ICF homes using the Nudura system. We have extensive portfolio examples available and can connect you with homeowners who are living in our ICF-built homes.

Absolutely. ICF walls are designed as Special Reinforced Concrete Shear Walls that meet IBC seismic codes and are ASTM E2126 certified. They provide far superior earthquake resistance compared to wood-frame construction.

ICF walls achieve a 4-hour fire rating, compared to just 45 minutes for standard wood framing. This is critical in California where wildfire risk is a major concern for homeowners.
