Transform Your Home With New Windows

Just like a camera lens, windows in your home frame pictures of the world outside. Transform your views – along with the comfort, beauty and value of your home – with new custom windows from Save Energy.

If you are looking to buy replacement windows, Save Energy has the solution you need. We feature windows by Simonton, Milgard, Marvin, and Cascade in a variety of styles and materials. If necessary, we can help solve special situations with custom solutions that are tailored to meet the unique needs of your home.


What are the Benefits of Replacement Windows?

Windows replacements aren’t just two pieces of glass stuck together in a frame. They are highly-engineered, technical marvels. Today’s windows do a lot more for your home than let in light.

Home window replacements can have huge benefits for your home and quality of life. New windows enhance the curb appeal of your home, protecting your property’s value and the equity you invested in it.

New windows can also reduce damage to furnishings by the sun’s UV rays. They can increase your peace and quiet by blocking outside noise, and stabilize temperatures in your home by eliminating hot and cold zones from older windows.


Our Home Window Installation and Manufacturing Process

All windows installed by Save Energy are custom made to your exact measurements. No off-the-shelf products from us. We can build and install windows that will blend seamlessly with any architectural style.

Our manufacturing process takes between 4 to 6 weeks. During this time, we make sure that your new windows fit the exact specifications of the windows that they are designed to replace. We also make sure that your retrofitted windows match perfectly with the architectural style of your home. With 35+ years in the Bay Area, we know a thing or two about the variety of home styles across Marin, Sonoma, and San Francisco.

After your windows are ready, the process of installing replacement windows in your home will take as little as 1-3 days. Unlike other window companies, we never outsource our work to contractors. All of our work performed by an expert team of installers who have been working with us for years. They know how to get the job done – and get the job done right!

Best of all, our windows come with a lifetime manufacturer’s warranty. If you want, we can even come back after one year for an inspection to make sure your windows are still meeting your needs.


Custom Windows For Every Home

Each home has a unique architectural style. To make sure that your replacement windows compliment the design and aesthetic of your home, it is important to choose the right style of windows.

Save Energy offers a variety of window styles that will perfectly compliment the look of your home. Some of our most popular windows styles include single and double hung windows, X-O sliders, picture windows, bay windows, and bow windows.

Regardless of the style of your home, we have the perfect windows that will not only make your property look more beautiful, but also help you save a bundle on your energy bills!


Choosing the Right Material for Your Windows

One of the biggest decisions in buying replacement windows is the material that your windows will be constructed from. At Save Energy, we offer new windows in a variety of materials, including vinyl, fiberglass, aluminum, or wood.

Each of these materials has their own unique advantages, both in terms of the look of your home and the possibilities for savings on your heating and cooling costs. In many cases, the price of new windows will be significantly offset by the money you save on your monthly energy bill.

Before you decide on new windows, our team will visit your home for a free estimate. We will inspect your home to give you a variety of choices to help you decide on the materials and styles that will work best for the look of your home and your energy needs.


Serving Homeowners Across the Bay Area for 35+ Years

Save Energy has been making homes beautiful with new windows and doors for more than 35 years. Our local window installers service homes throughout the Bay Area, including Marin County, Petaluma, San Francisco, San Rafael, Santa Rosa, and Sonoma County.

If you want us to visit you, we can come right to your door for a free in-home estimate on new windows and doors. But if you prefer to come see what we have to offer and order replacement windows at our store, you can visit our showrooms, located in Petaluma.

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...!
