I appreciate Donovan and the whole crew every day, but especially now with the cold and snow settling in. The windows are fantastic, and the special one he tracked down for me has honestly been a dream come true.

Morgan Merriman on Lomax Window & Door Co.

We recently had 17 windows and a new back sliding door installed on a home we flipped. The entire process was seamless. Donovan, the owner, was so knowledgeable, upfront and honest. Then the windows arrived and were installed in a day and a half. TJ and his crew did a great job installing, and did a great job of keeping the place tidy during the process, which was important since staging furniture was already in place to sell it. Overall, I was blown away by the process and will definitely be using LoMax again in the future!

Steve McKee on Lomax Window & Door Co.

The window install went very smoothly yesterday. The installers, Logan and Jeremy, were better than good, they were awesome!

We asked them many questions along the way...probably more than we should have, but they were very patient and answered all our questions. Both of them were very knowledgeable and a real pleasure to work with.

Donovan guided us down an excellent path with the Sierra Pacific H3 window product with i89 coating. We live in a harsh mountainous weather environment...high winds, extreme cold (and heat), at elevation (~7800ft).The windows turned out better than we expected. The windows are beautiful...especially the big one (67" by 67")! They are well insulated and provide greatly improved comfort.

Our neighbors even came over to see our windows and were amazed at how nice they looked. The external finish was crisp and clean. We used knotty alder wood for the internal trim which turned out beautifully.

I would highly recommend LOMAX for your window needs.

Nice job, thank you.

Cierra Walker on Lomax Window & Door Co.

I was looking to refurbish or replace some of my very old houses' non-functional, wood windows. It was important to me to maintain the old charm of my house, but also improve the energy efficiency. I talked with so many companies, both large and small, and nearly all tried to sell me on white vinyl windows. Lomax was the only company that offered alternative options, like refurbishing and/or wood sash replacements at a reasonable price.

The results are fantastic! I now have functional, beautiful windows that maintain the character of my old home. I had some additional requests (downsizing a window) that Donovan and his team were able to accommodate. They have been great to work with from start to finish, and I can't recommend them enough. I will definitely be calling them when I replace the rest of the windows in my house.

Rick Cardwell on Lomax Window & Door Co.

We were very impressed with the professionalism and response of the team at Lomax Window. Donovan was timely, addressed our concerns, solved the problem and overall was just amazing customer service for our Sierra Pacific windows. Lomax Windows did not do our build/install but as a local Sierra Pacific dealer, took care of our concerns. Addressing our needs was greatly appreciated, we will definitely use Lomax for any window needs in the future. Thank you Donovan!!
