Ganahl Lumber Company - Costa Mesa

See All Reviews
Ganahl Lumber Company - Costa Mesa is rated 5.0 out of 5 by 18.
Rated 5 out of 5 by from Nice windows & doors... I like Milgard because of the quality, ease of installation, and smooth operation of the windows and doors after the installation is complete. Ganahl Lumber Company of Costa Mesa and salesman Gabe Quesada Jr. have been helpful in selecting the appropriate Milgard windows & doors for the customers’ needs.

Rated 5 out of 5 by from Saved me tons! At first i went to home depot to help me with my order for windows. They gave me a quote with installation included and if my friend hadnt told me to check out Ganahl, i would have purchased those windows. The guys at Ganahl lumber whole saled me the windows, and hooked me up with an installer that did a great job! I ended up saving about $6,000 on my project by going through Ganahl Lumber. Not only did they save me money, but they really know their stuff! I came out of that first meeting as a window expert, i know when to temper a window, what low e glass is, what title 24 is, the difference between retrofit and new construction and that is all new information to me! Whole new level of customer service here. These people usually deal directly with contractors and that is a huge advantage over a place like home depot.

Rated 5 out of 5 by from Awesome service and product! We are so happy with our Milgard Windows and doors! We used the Trinsic painted Bronze and love the look! The French doors and sliding patio doors compliment the back yard. The service from Milgard and Ganahl was top notch and we couldn’t be happier!

Rated 5 out of 5 by from Extremely knowledgeable and UNBEATABLE service! As a building professional, I consistently purchase and install windows. Ellysia is one of the most knowledgeable and responsive reps I have the pleasure of working with. Ganahl's showroom also makes it a breeze to send clients in for a product tour. I would not hesitate to recommend both Ellysia and Ganahl Lumber, for all your window needs.
