"Second time hiring Action windows and I wish I could hire them for everything. Where it counts us if you have an issue and how it's handle. Small. Problem was handled asap and they even sent manufacturer out right away to repair it. Said they would do it themselves if necessary. Wonderful superb company to work with. You won't be sorry. I look forward to siding next with Action windows and siding."

"I was very satisfied with the work and plan to hire him again. I was especially pleased with the work he did hanging curtain rods and solving other window problems. He did not require a lot of supervision but did ask questions when he needed my input. He also stayed until everything was done and I was satisfied with the work. I was a little concerned about the cost but he stayed within his initial estimate and did such a good job on so many different types of tasks that I felt the extra cost was worth it."

"We had windows replaced and could not be happier! Brad and Rick from NuFace were very professional and courteous. Their work is second to none! They worked non-stop even when it started raining. They took out and discarded the old windows. They installed the new windows, calking and flashing. My wife was pleasantly surprised at the beautiful job that was done. We recommend Brad, Rick and NuFace to EVERYONE that is looking to have new windows installed!"

"Very professional and presented multiple options. We chose the middle option which was definitely the correct choice. They also checked my smoke alarm because I did not on the ladder and unable to reach that high. They left the jobsite cleaner than it was when they got there! If there was a way to give six stars they would get six plus!!!"
