window replacement sonomaLooking for the best window replacement and installation contractor in Sonoma County?

At Save Energy Co, we’re committed to making the house of your dreams even better than you dreamed possible.

Part of the charm of living in Sonoma is the vast array of architectural styles found throughout the region. Farmhouse, Victorian, Craftsman, Adobe, Architectural – they all seem to work together creating a visual richness and harmony you’d be hard-pressed to find anywhere else.

This variety makes it particularly challenging when it comes to making home improvements like replacing worn out or energy wasting windows. Is there a contractor that can handle so many different styles and diverse construction techniques?

Save Energy Co has been serving the needs of Sonoma homeowners for over 35 years.

In that time, we’ve literally seen it all and worked on them all  — successfully. Here’s why: We don’t offer off-the-shelf products for your home. Everything we do is custom.  Custom measured, custom built… but only after you’ve sat with one of our home improvement specialists in the comfort of your home for a no-pressure, free, needs and wants consultation session.

We’ll learn a lot about you during this time and you’ll learn a lot about us and what we have to offer as solutions.  You want wood, fiberglass, aluminum, or vinyl as the construction material?  We can provide them with all from well-known manufacturers that will be perfectly suited for your home.  Most of our customers want time to think about all the options available to them and that’s perfectly fine with us.  After all, we did say the consultation was “no-pressure.”

Even with every job being a custom order, our years of experience have helped us create an ordering and installation process that ensures you’ll be satisfied.  Home improvement projects can be daunting. That’s why we make certain you know what’s going to happen, what to expect and when to expect it.

Our installers are skilled craftsman, certified by our manufacturers.  They’ll bring their expertise to your unique house and upgrade your windows typically in a day. Of course, large projects may take longer.  Just be assured that, regardless of the number of windows being replaced, each will be installed with the care and skill required to make it perfect.

Experienced Service with the Reviews to Match

All of our window manufacturers carry lifetime warranties on their products. We also warranty all our work for the lifetime of the window or door. If you’d like, we’ll even come and inspect our work one year after completion.  And speaking of completion, you’ll never have to worry about the mess home improvement projects can leave.  Our installers always thoroughly clean up when they’re finished.

Save Energy Co has received over 90 5-star reviews on Yelp, many of them complimenting our installers for the work they’ve done and for cleaning up so meticulously.  We’re the only business serving Sonoma and the surrounding region to be Diamond Certified Custom Windows Installers for 21 consecutive years by American Ratings Corporation, a third-party quality assurance enterprise.

With all of our versatility, experience and skill, the one thing we’re most proud to offer our customers is peace of mind.

Many homes in Sonoma CA and the surrounding area feature multiple styles of windows.  This adds charm and visual interest. Save Energy can match any style of window because they are all custom made to exactly fit the measurements of your original window opening.  Want to make an opening bigger or smaller?  We can do that, too.  Your wish is our command.  That’s the magic of new and replacement windows from Save Energy Co.
