What Our Clients Are Saying


Jesper P.


We were given a great quote for solar panels, and Josh was easy to work with and he was very knowledgeable and able to explain everything related to the solar and answer our questions. I’d definitely recommend reaching out to him if you’re thinking about getting solar for your house!



Rocky B.


We found Sustainable Construction from our neighbor who was very satisfied with their new windows, the price and especially their work product. We called Josh and were taken by his no pressure, straight forward assessment of what we wanted, and options to achieve it. We appreciated his thoroughness and accepted his offer to do business. When the windows and patio door arrived, Josh’s team were courteous, professional and extremely prepared for their task. Josh understood that I have a respiratory issue and the installation team put on masks before entering our home and wore them through-out. Every detail of the installation was done to perfection, checked and double-checked to the last detail. We are more than satisfied with the windows, patio door, and the work that was accomplished. We are already planning another project with Josh and his company.

Did a second project with Josh and his team and planning on doing a third. Josh came out and helped us insulate our attic and a few walls, plus a few new windows and was just as professional as before. Projects were prioritized and completed on time, all the workers were careful with our home and kept the work area clean and were responsive. We also had our HVAC ducting updated and optimized, overall I’d still recommend josh and his team as they take great care throughout the entire process and are responsive and professional as ever. We plan on getting solar installed as well before NEM 3.0 takes affect, and josh has been helping out with that.



Amv V.


We reached out to Josh @ Sustainable Home Construction about replacing some vinyl windows. Other companies said they had up to a 90 day turnaround time, Josh not only provided the best price but a 2-3 week turnaround time. The windows arrived earlier than expected and are exactly what we needed. Josh was responsive and professional the entire time. We will definitely be utilizing his services again.



Stephanie F.


We had our attic insulated. Management is quick to respond and schedule a time to come give an estimate. Prices were reasonable and the work was done well. We’ve already seen significant improvement in our AC usage this summer. Highly recommend.



Sheree S.


Josh and his crew are outstanding. Goes out of their way to ensure you are satisfied with the job. We went with them because their prices beat all our other quotes. You wont be disappointed if you choose to do business with this honest company.



Karen Gutierrez

I would highly recommend using Sustainable Home Construction. We hired them to install insulation in the walls of our home and do the patch/paint afterwards. They provided these services at a fair price, arrived on time, did exactly what they said they would, and respected our space.

Thank you Sustainable Home Construction! We are SO happy that we chose them for our AC System installation. The work quality and the exceptional service made this experience trouble-free. Roman was amazing, he was very professional since day one and took the time to explain the process and answer all of our questions. He also walked side by side with us through every step of the process and offered different options for our home. Honestly, I was expecting a longer completion time but thanks to their expert crew, they were able to complete our project in a timely manner. Thank you Roman and Sustainable Home Construction for helping us stay cool this summer!

Jeremy Michael Cohen

Roman and his team quoted, manufactured, and installed custom windows all within in a few weeks.
Roman was a pleasure to deal with. He was professional, courteous, and quick to reply on the phone, in person, and via email. There was no hard sell, and the quote was lower than we were expecting.
The windows exceeded our highest expectations. Roman under-promised and over-delivered. Our place is now quieter, cleaner, and cooler than we could have expected. The custom colors looks great. The windows operate perfectly.
I give Roman and Sustainable Home Construction my highest recommendation!

Paulina Ho

Josh and his team came out to my home to replace a large custom patio door. They were professional and competent through out the entire process. Josh personally visited the job site to ensure the work was done to the utmost customer satisfaction. Additionally, I had a minor follow up issue in which Josh so graciously helped me resolve. Great company, great work ethics and excellent customer service! Definitely recommend them to others!

Azizi B

Requested an estimate for complete HVAC upgrade and a few smaller projects…Josh contacted me, met w/ me, provided a detailed written quote, followed up to ensure they were offering what was requested by me, and kept me informed through the process. I had previous estimates from different companies but most of those sales representatives focused on the finance/sales/pricing and not the need/concerns/info requested by ME, the consumer. All the workers showed up prepared to work & the results of each project reflected in the quality of the job. Sustainable Home Construction values their customer and made my life just a bit easier when they took care of my home. Josh was so professional & offered customer service beyond my expectations, for that I am grateful. I will definitely work with them on future home improvements/upgrades.

I needed an HVAC replacement so shopped around. I got five quotes and Art’s quote was not quite the cheapest, but it was the quote that gave me the most confidence in the job. They detailed everything about what they would be doing including patching and painting the closet where the old HVAC was. When the job was done, we finally had a quiet split system installed in our attic and couldn’t be happier. I won’t hesitate to recommend Sustainable Home Construction in the future.
