From San Francisco to Santa Rosa, when homeowners need installation and replacement services for exterior doors, they rely on Save Energy Co. Our 35 years of experience selling and installing doors means we have the skills and knowledge to complete your project right the first time.

Door installation projects can be tricky. Houses settle. Door openings aren’t always perfectly square and true. If vapor barriers aren’t installed properly, water can leak in or air drafts can occur. You need a door contractor who can get the job done right the first time. We guarantee our installation work and will do an inspection of it one year after completion, if you request us to do so.

What type of door needs to be replaced and installed – entry door, patio doors, French doors, or sliding doors? We offer a wide range of styles from the leading manufacturers of wood, fiberglass and vinyl.

It was not an easy job but, Save Energy came ready to go right on the time and on the date promised. They brought enough man power to handle the installation of a large dbl French door and an additional 45" window. Additional Framing was required and stucco removal. It came out great, clean up was great.Thank You again, Save Energy Company

I couldn't be happier with this outfit. The whole project was challenging but they pulled it off without a hitch! From Tina who bid the job to John (the owner) who was always there when I needed him, to the ladies in the office and the excellent installers. What a great company! If you need a window or door installed you can't go wrong with these folks!

Wow! We went to many construction companies trying to get three windows installed in our condo. Save Energy was more than willing to take on this small job, gave us the best price of the those who would even come out, were on time, quick, clean and did an excellent job. Can't recommend them highly enough!

Save Energy is a local, family owned company that does excellent quality window replacements for historic homes. We have a historic home, and we purchased wood clad replacement windows through Save Energy. They are very familiar with the needs of a historic home and were able to point us toward the right product. They communicated well and responded to all of my inquiries in a timely manner. Their installation team did incredibly fast and skillful work replacing our windows and saving our historic window trim in the process. We were extremely pleased with their services and we are in love with our new windows!

Save Energy Company is a local company who exceeded my expectations for the replacement at our 26 year old windows in our East side Petaluma home. All the employees provided exceptional communication, were all very professional, cleaned up as they worked, very efficient, engaging and personal, even during this Pandemic in October of 2020. I highly recommend using this company. Ask about the zero percent financing options. We are enjoying the benefits of these new windows already. Only wish we done this earlier.

We had old drafty single pane Aluminium windows.After having really bad and frustrating experience with some big Brands, I decided to go for local company. Save Energey came showed mostly five star reviews online.The entire process from the Appointment to installation went very smoothly. John, Tina, Jeff, Ahoa, every personnel gave amazing customer service and professional. Tina and John came completely prepared with COVID19 safety in mind. They took every little detail and need into consideration. Great work ethics and professionalism. Jeff and Ahoa did an excellent job with Installation. Save Energy has proven to be reliable, punctual, responsive! We are extremely pleased! Highly Recommend them.Here are some tips I wish I had known before:1) All windows are custom made to fit specific needs so make sure you let John know all the changes when he comes for final measurements.2) Discuss your needs in detail: Which way you want to window to open, tint/insulation, Standard window screen vs something else.

We used Save Energy Co for two phases. The product( windows and sliding doors) are of high quality. All the meeting were on time. The installation was professional and scheduling was a breeze. If I have another project in the future there is no doubt I would use this company again.

I had two front doors taken down to one large door with two side panels and it is BEAUTIFUL! We were doing remodel work when the SIP and Covid 19 all came in to play so these guys had to put off the work for a bit but as soon as they were able to go back to work they installed right away and it looks gorgeous. A pleasure to do business with.

10 years ago Save Energy came out and replaced all of the old aluminum windows in our fixer upper. This included a beautiful new construction 10x8 picture window which gets compliments every time someone new comes to our house. 10 years later and we finally got around to replacing the broken back door and sticky front door with beautiful new mid-century inspired doors. They look great. Save Energy will always stand behind their work, so if something isn't quite right (and let's face it when is a construction project without one hiccup) they will answer your calls and come and fix it. They are pleasant to be around, dedicated and do a great job. Oh and their prices are really great. The only thing I think they could improve is the sales/design process as you end up with a bunch of pdfs via email and no streamlined way to order, it's confusing and results in time wasted, but that's my only complaint really, I think they're fab and i'm very picky Lol.

Save Energy replaced our swinging french door with a vinyl slider. We couldn't be happier with the price, product and installation. All our interactions with them were timely and professional. We would definitely use them for future work.

The windows in my condo were original to the 1974 construction and very drafty and noisy. I was nervous to replace and asked my neighbors for recommendation, Save Energy came very highly recommended, not only for quality of work, but also for affordability. Not only was that true, so was their professionalism, follow-up and communication. This was one of the best experiences I have had with a vendor in a long time. I HIGHLY recommend.

Both my Mom and I had to call multiple times to correct a problem w/ a faulty slider. They were terrible about calling back. A man that has since been fired came out and put a band-aid on the problem that didn't last. The owner John came out and said he'd split the cost of a new slider. I made a down payment of $200 that cleared my bank March 5. John advised a couple weeks for order to come through. In early April I followed up again. After further delay the slider was installed on April 24th. Then I come to find out the cost of the slider and realize John didn't split the cost and charged an unfair price! Absolutely, horrible company that didn't do the right thing! Shameful owner and a company NOT to be trusted!

Highly recommend Save Energy for your window installation. John and his staff are on point with every detail. The crew that installed the windows were good but I did have to correct a few minor items with them.

Jim came out and did a consultation. He answered all of my questions and returned a competitive bid in a timely manor for 13 windows I explained we had a time crunch for moving into our house and they really went out of their way to get us on the schedule ASAP. I think we kinda made it hard on them. Jim did the bid on an empty house and we had moved furniture in by the time they arrived, ahead of schedule. The crew put plastic over everything and did a great job cleaning up. I couldn’t be happier, my wife and I are happy to recommend Save Energy Company.

From start to finish, A #1 positive experience! Office staff was helpful, knowledgeable, and friendly! The gentlemen that came to install the window were fabulous; on time, very capable, and paid the greatest attention to making sure our home didn't look like a war zone by covering all areas with tarp to protect floors and surfaces.Something else worth noting; rain was expected on the day that they were scheduled, and they still came! Thank goodness the weather gods smiled favorable on us, and held off until they were finished... Thumbs up for the good work, and dedication :)Thank You...!
