California Window & Solar runs a tight ship. We analyzed hundreds of reviews and found zero complaints about workmanship, which is rare for a window installer operating at this scale. One customer came back three times over nine years, replacing doors and windows in multiple properties, and still raved about the install crew not damaging her stucco. Another noticed a leak during a rainstorm nine years after installation, called the company, and got all her windows inspected and repaired for free under warranty. The family-owned structure shows up in the details: the owner Dallas handles measurements personally, the same install teams return for repeat customers, and 59 reviews mention post-sale support without a single negative comment. We did notice the company earns bronze and silver awards in its market rather than sweeping golds, suggesting you might find slightly faster timelines or sharper pricing elsewhere. But if you want an installer who'll show up on time, protect your floors, and still honor a lifetime guarantee a decade later, this is a safe pick.
If you prioritize finding the absolute lowest quote, you may discover cheaper options. But if you want an installer who answers the phone nine years later when a window leaks and fixes it for free, the modest premium buys real peace of mind.
K Cull had new windows installed throughout the house nine years ago, and the workmanship and materials impressed them from the start. Two months ago, during a heavy rainstorm, they discovered a leak in one window and called California Window. The company sent a technician out immediately; he inspected the whole house and repaired every window he checked — and because the installation came with a lifetime guarantee, the visit and fixes cost nothing. What stood out was the warranty actually being honored years later and the prompt on-site response: a family-owned business that has operated from the same location for years, so the support continued long after the sale.
This homeowner called California Window & Solar back for a follow-up job after a previous positive experience. Justin returned to lead his crew and oversaw the replacement of a back garage utility door that termites had destroyed; importantly, they managed the work without nicking the stucco or foam trim around the opening. The team also replaced a leaky, inoperable double-hung bathroom window and took care to protect the wood and tile floors, leaving the interior spotless when they finished. Dallas handled the measuring, proposals, and contract work again, and the office staff stayed responsive throughout. Because the company is family-run and does not subcontract the work—something that mattered a great deal to them—the homeowner appreciated the continuity and meticulous attention to detail and plans to call the company again if another need arises.
Linda hired the company to replace eight windows in her home and immediately connected with Brittany during an in‑home walkthrough. She met Brittany and then watched Brittany and Dallas arrive on time to take precise measurements, which made the whole process feel effortless. Installation happened quickly, the crew left the site spotless, and a string of follow‑up calls and emails checked that everything met expectations — so much so that she felt more than satisfied. The Milgard windows ended up looking beautiful and crystal clear, and the price compared favorably to the other two companies she contacted. What stood out most was the combination of punctual, personable staff and thorough aftercare — that attentive service, paired with the pristine new panes, is what she’ll be telling friends about.

Tony Gmitruk returned to California Window & Solar after using them at his previous house 12 years earlier, and recently hired them again to fit 20 windows and three French doors in his current home. He appreciated Jeff’s help during the proposal stage—Jeff walked him through several options until they settled on the right combination. During the install he encountered a courteous, professional crew who left the job looking clean and solid; he ended up extremely happy with how the new windows and doors perform and look. One surprise emerged after the work was finished: the Milgard products they used don’t come with pet screens, so he had to arrange those afterward. Bottom line: the team delivered thoughtful guidance and tidy installation, but pet owners should plan to source pet-friendly screens separately.
Terri C. first hired CA Windows on Redhill several years ago, and when a few windows finally needed replacing she turned to them again. She found every touchpoint — sales, administration and the installation crew — consistently knowledgeable, professional and polite. The company stood behind both their products and their work, so the replacements went smoothly and without surprises. What stuck with her was the across-the-board reliability: the same competent people handling every step made calling them an easy choice.
Tom has relied on this family-owned solar company for ten years, first for a system on his home and later for his daughter's house. Over that decade he experienced consistently fast turnaround and a team that answered quickly whenever he needed them. He valued the continuity a family operation brought — familiar faces, prompt replies and dependable follow-through across both properties. What sticks with him after ten years is the steady responsiveness and speed that kept him coming back for two households.
Rich Smith had worked with Brittany for a couple of years while she guided him through product updates and pricing. When he finally pulled the trigger on replacing windows and doors on his home, Brittany and the California Window and Solar installation team mapped out the schedule and delivered exactly what they promised. The new windows and doors look great, operate smoothly, and the crew left the house clean inside and out at the end of each day. He walked away remembering Brittany’s steady attention over time and the installers’ daily cleanup — small details that kept the whole project feeling professional from start to finish.
Alex W. had purchased sliding doors from the company years ago and they’d held up well. When his youngest child broke a handle, he went back to the showroom expecting a long parts order — but a representative offered to contact Milgard and then walked to his truck, dug around, found the exact replacement, and handed it over on the spot. The immediate, hands-on solution — not a promise to call back — made the difference: it felt like someone was genuinely determined to fix the problem. He left with the part in hand and the sense that this will be the first place he visits when he needs another door.
JoAnn A. had new windows and a sliding glass door installed on her home about a year ago and is writing now to express her thanks. She walked away with a finished project she truly loves — the team did a terrific job, and the new windows have become a frequent conversation starter. She still gets so many compliments from neighbors and visitors that she calls the upgrade the single best thing she has done to her house. She specifically thanked Dallas for everything; what lingers most is how visibly the house changed and how often people comment on it.
Karen Carnahan has lived in her house for over 20 years and has hired the company multiple times to replace windows. She wishes she had discovered them sooner. Every time they finished an installation, the new windows transformed the look of the home — consistently impressive, clean work. The whole experience felt professional from start to finish: the owner handled details, the office staff kept things organized, and the installers left sites tidy. What kept her coming back was the combination of that high-quality finished appearance and a team that was genuinely easy to work with.

Kathy G. needed new windows and, after seeing good local ratings, reached out to California Window & Solar in Costa Mesa to confirm they served her City of Orange address. She found the phone contact personable and efficient and arranged an appointment for Jeff Conkle to come measure and provide an estimate. Jeff arrived on time, ran through a professional presentation and detailed measurements, and the estimate showed up the next morning — she signed on. The installation crew showed up as scheduled and installed Milgard windows cleanly; when she asked for two sliding screen doors to glide more easily, the team adjusted them on the spot. A year later she called Jeff to replace the last two windows and the whole process repeated with the same smooth timing and attention to detail. The standout: consistent, on-time service that left her with beautiful Milgard windows and no lingering punch-list items.
