I highly recommend Cornell Construction in Placerville CA for their exceptional work. They did an outstanding job replacing a broken window and sliding glass door. Replacing the front porch posts due to dry rot and Sean also added an electric outlet and had a Moen Smart Water Shut-Off Valve installed. The project was completed on time as promised, and their team was consistently punctual. They also took the time to answer all of my questions and ensure I was satisfied with the work. I am very pleased with the results and would definitely use their services again.

Sean and his team were extremely professional and took care of a pocket door that was no longer "rowing" and looks beautiful!

California Energy Consultant Service

My experience with California Energy Consultant Service started with an insulation estimate from…read moreMitch. He was knowledgeable, straightforward, and took the time to explain the project and costs. We were getting quotes from several companies, so we hadn't made any decisions. What really stood out was that Phil, the owner, personally reached out that same evening to ask how the appointment went and whether our questions had been answered, regardless of whether we hired them. Coming from an HVAC sales background myself, that meant a lot to me. I've always appreciated family-owned businesses, and an owner who takes that kind of interest in a potential customer says something about how the company operates. Phil and I ended up talking about a roof replacement we were also planning. I'd already met with six roofing companies, but that conversation convinced me to get one more estimate. We ultimately hired California Energy for both the roof and insulation. What followed was a complicated project with multiple contractors working at our house, changing schedules, and a few unexpected problems. California Energy has been very accommodating throughout. Jamie, our project manager, deserves a tremendous amount of credit for coordinating everything. She's had to work around other trades, adjust schedules, and keep things moving while making sure our concerns were addressed. I know it hasn't been easy, and I genuinely appreciate the effort she's put into it. I've also had the opportunity to work briefly with Tony, another project manager, who has been incredibly responsive, helpful, and willing to step in whenever needed. John and Oscar, who handled the roofing work, have been excellent. They've been professional, attentive to details, and willing to follow through on questions or concerns. I genuinely have no complaints about my experience working with either of them. The roof is now complete, and the old attic insulation has been removed. We're waiting to blow in the new insulation until some electrical work is finished, with a few minor items still to wrap up. I also want to give Jose a special shout-out. While working at our home, he noticed an existing issue with our HVAC system that could have become a very expensive problem. Instead of simply pointing it out and moving on, he advocated for us, communicated with our existing HVAC contractor, and helped get the issue thoroughly investigated. That ultimately led to the discovery that our two-year-old rooftop HVAC unit was defective, and our HVAC company is now replacing it. Jose could have easily considered that someone else's problem, but he didn't. We're extremely grateful for his attention to detail and persistence. Thank you, Jose! Not everything has gone perfectly, but with a project of this size, I don't expect it to. What matters to me is how a company responds when legitimate concerns come up. In my experience, California Energy has listened, communicated, and worked to make things right rather than brushing us off. That speaks volumes about their commitment to customer satisfaction. One thing that really stands out to me is how many employees I can name: Mitch, Phil, Jamie, Tony, John, Oscar, and Jose. Each has made a genuine impression and contributed to helping us navigate what has been a challenging few months of home projects. I think that says a lot about the people this company employs and the relationships they build with their customers. That kind of personal connection and accountability is becoming harder to find, and it's something I truly appreciate. We still have the insulation installation and a few finishing touches ahead of us, and I plan to update this review once everything is officially completed. Obviously, I can't speak to what their customer service will look like years down the road, but based on everything we've experienced so far, California Energy Consultant Service has earned an A+ from me. Phil has set a strong example as an owner, and his team has backed it up. From the initial estimate to managing a constantly evolving project, everyone involved has played a meaningful role in making this experience a positive one. I'm grateful we chose California Energy and appreciate everything their team has done for our family and our home.

The positives: Great communication, Alonso, Omar and Oscar…read morewere very attentive to detail and spent a lot of time making sure the end product of the windows and new trim is excellent. The negatives: a broken sprinkler, poor communication about permitting. Overall, we are very happy with the windows themselves. I wish the other details had been a little better, but big picture is that we are happy with the three contractors who spent all day in the sun and yet just powered through, not sacrificing quality work. Communication improved later, and we can already tell that these windows are better at keeping heat out than the old ones.

They're very happy with the windows we got from Clear View Windows & Doors a few months back. Today…read moreis a great day to write a review when it's 100° outside and inside the house without air conditioning it's 74 degrees at 3PM. Jason and his team did a great job putting in 27 windows, I would recommend them highly.

Incredibly happy client as I write this review for Clearview!…read more First, I reached out to Clearview and they came out to quote next day! And on a Saturday. Ok...that was first impression...it gets better. On the quote appointment, they surveyed the home and provided me a catalogue to view while they did measurements (lots of window types and options!!!). During our conversations, they were so easy to work with and genuinely cared about our project like it was their own home. They made quality suggestions that we as homeowners didnt even know or think to ask about, such as, sound barrier windows or adding tint. This was our second quote and the prior company didnt ask or suggest these options at all. They just order took and quoted. Not these guys! They further impressed us by going through the Anlin window warranty which is LIFETIME! The warranty alone is worth every penny, but Eric and Jason's passion for what they do and the tenure/experience they have in this industry were really why we chose to hire them. From quote to install they were on time with all timeliness given (which is so rare in this industry) and gave us options that other companies didn't have access to. They promised quick and effortless experience and they nailed it. They promised to install ALL windows in my home in one day...I truly didnt think it was possible and they proved me wrong. Not only did they complete it...they did all the trim work and installed it to perfection! We included paint services and the painters that came out were incredible and amazing as well! Very detailed and meticulous and VERY respectful of our home. We had just wrapped up 7 weeks of construction and the professionalism Clearview's workers showed was night and day and far superior. If you want great communication, fast and timely services, all at a fair price and lifetime warranty for great quality windows...hire these guys. They genuinely care about the work they do and care about having a happy customer...cause that is what I am right now! I honestly cannot recommend these guys enough! My windows are GORGEOUS! Pricing was competitive! AND service was PHENOMINAL!

We want you to know we highly rate ALL of you at ALL levels especially Chad LaMantain your Sales…read moreRepresentative that was sent out. Chad was very easy to speak with about what we were interested in and why and also was respectful about what we weren't interested in. We felt he was open and honest with us and it made it easy for us to select what was best suited for us and our home. He did an EXCELLENT job of representing your product and company to the point we did not even get a 2nd bid we felt we could move forward with Northwest Exteriors Inc for our new home windows. The financing offered too was a real plus. We have found that in todays world its very difficult to get HONEST help and to have others in your home for extended periods of time but we felt that Sean the measurement person and the installation guys Tim and Mitch too were all very professional and business like. We also seldom recommend anyone because we have found that either the contract isn't honored or the quality of the workmanship or product is less than desirable but we again found thus far at ALL levels of Northwest Exteriors Inc. it was a pleasure to do business with your company and we would highly recommend you to anyone that needed windows etc...etc... We hope you maintain your HIGH STANDARDS because in the future we may need new siding and your sign still remains in our front yard because we are so happy with our new home windows. Your office staff both Ashley and Monique also were easy to communicate with and were on top of their jobs too. Thank you so much and we wish you ALL the very best at Northwest Exteriors Inc., Anne and Joe B

Bryan was our salesman and he provided a very competitive bid. We also preferred Anlin windows over the other companies. Btw, make sure if you're replacing just the glass know that it will NOT match your other windows (due to title 24)
