Energy Core Construction installed a new roof in Riverside, CA. We replaced the old leaky roof with the new Owens Corning roof that features a 50 year warranty. The homeowner Linda D. has noticed the difference immediately. The new roof lowered her electric bill and made her home more comfortable.

Energy Core Construction worked on a window, door, and HVAC system replacement in Escondido, CA. When the latch system on Dennis’ sliding door failed, we came and replaced it with a brand new French patio door. Dennis received our veteran’s discount on his entire installation and now has brand new energy-efficient products installed in his home that will reduce his monthly energy costs and keep his house comfortable.

“Good job, I love the windows. Energycore Construction cleaned up the debris after the job and the installers were very courteous and professional. Eric helped with explaining the windows and Taylor measured.”

Ellen W, Rialto, CA

“Eric and Taylor were very helpful and informative when it came to choosing our new windows and backyard door. Installation day came and the workers were polite and efficient. Cleaned up after themselves and left no mess behind. Amazing transformation on my home and will have to get in contact in the future for some patio work. Thanks, guys!!

Sarah M, San Diego, CA

“Energy core construction was truly a blessing. Eric came out and was so knowledgeable and kind. My windows made my house look like new. I would buy them again in a heart beat. But I won’t t have to with my double lifetime warranty. Thanks, Energy Core Construction…”

Tanesha J, Apple Valley, CA

“Job well done by Taylor, Dean,  Danni, and the installation crew. These doors and windows truly block out the unwanted noise and elements as promised.  I look forward to completing the rest of our home. Bravo!!! They really did an amazing job. I really trust their collective work ethic.”

Ruschka S, Los Angeles, CA

“Mike and his three-man crew knocked it out in three days. Our house was full of challenges and they work through all of them with a smile. He put everything away nice and clean and worked around all of our stuff. I would give them more stars if I could.”

Crystal G, Temecula, CA

“These are the best windows ever! Our old windows one would hear everything happening outside.  We live on a busy street. Lots of traffic noise in a residential area. Closed up due to a recent heat wave.  I don’t hear any noise. For the first time ever our house it quiet.  The outside noise stays where it belongs…outside.”

Gerald T, Laguna Woods, CA

“Energycore did a great installation. We noticed a difference in the noise levels with the street. The windows installed matched the rest of the windows in our home. Installers cleaned up and we got great value in the product.

Art T, Diamond Bar, CA

“Got windows installed on my house and after the installation, I noticed that standing near the windows I didn’t feel the heat from outside like old windows. Dealing with energy core was also very easy since they kept us updated on what was going on and when the installation will be started.”

Francisco C, San Bernardino, CA

“I can’t say enough good things about the work that was done and the people at EnergyCore. Everyone from the Sales Rep to the Project Manager was top-notch. Taylor and Richard you guys rock!! We are forever grateful for the job all of the crews have done to bring this idea to life!! Thank you!
