What Customers Have To Say!


I wanted to replace nine windows in my secondary residence - a modified hunting cabin in the woods in northwest Virginia. The home was over forty years old, and the windows were leaky and difficult to open. Some were second-story requiring ladder work.

I got in touch with Dave through a friend who is a realtor. I currently reside in New Jersey and was doing this job "remotely". Dave had an estimate for me within a week, and it was very reasonable. He included a website on the windows that he would be installing--highly energy-efficient, argon infused - and requested 50% down and balance upon completion. He made it clear that the job would be done roughly two weeks after the down payment had been received to allow time for the windows to be ordered. Sure enough, 12 days after our transaction, he notified me that the job would be scheduled. He actually did the work the day prior to his scheduled date because he had his full crew available to do the job. The work was completed the same day - removal of the old windows, replacing any worn/rotted wood, new windows installed, exterior framed in fresh aluminum, and a very thorough clean-up. I was down to see the work for myself last month and I could not be happier! I am going to ask him to replace a door and a slider based on his high-quality performance with the windows!

From the first phone contact with David at Energy Windows, I knew he would probably be my choice. He was straight-forward and gave me the information I needed to make a decision, whether it was his company or one of the others with which I had appointments. He was on time for our appointment and insisted on showing me his product, even though I had already decided Energy Windows was my choice. After his presentation I was more convinced than ever. This man knows his windows. We signed a contract and he placed the order. The day of installation, he was on time and immediately got to work. As promised, the install was one day. Beautiful! There were two panes slightly damaged and David had ordered the replacements. His crew was polite, exceptionally neat, and did a GREAT job! I am thrilled. We have plans for additional work and I could not hesitate to recommend him to anyone. As an aside, my kitchen window has a sun shade in which the birds have nested for years. They removed the shade, but in the window, and reinstalled the shade. Bird nest intact!

So glad I found Energy Windows! Professional to the max. Beautiful job, reasonably priced, with a great product. Would recommend them to anyone. Love my new windows!

Description of work: Energy Windows LLC came out and replaced 4 windows.

“I contacted Dave at Energy Windows to replace all of the windows in our 30 year-old house. The existing windows were loud and drafty and repairing them had become more difficult over time since parts were hard to find and increasingly expensive. We had 16 windows that were all odd sizes and were a unique style.

The entire process was quite straightforward. Dave scheduled an initial meeting right away and brought a variety of product brochures and samples. We discussed pricing options, features, styles, and eventually settled on an approach that fit our budget and kept with the style of the house.

The ordering process was simple and Dave kept us aware of delivery and install dates.

On the dates of the install, the Energy Windows crew showed up on time and were professional and courteous. There were no surprises and despite the house having some very unique construction features the replacement windows were installed quickly.

I checked in on the progress out of curiosity and everything looked to be executed properly. The install took two days and when we got some storms it was obvious overnight which rooms had new windows and which were original.

All of the finish work was clean and the crew took great care with drop cloths and masking. The site cleanup between days and after the project was outstanding.

Overall, I highly recommend this company.”

“I contacted Energy Windows after my mower threw a rock through a window at my house. My call was returned immediately by Dave and my window was taken in the same day. Once he checked it out he laid out my options and let me know the best route to go. Once the new glass came in it was professionally repaired and returned to me and looked absolutely perfect as it had never been broken. Thanks to Dave for saving me time and money! Great job!”

“We had a broken window and called Dave at Energy Windows to see about fixing it. He clearly laid out our options. He made us feel like he was treating this window repair like it was on his own home. He was very exacting in his work, and now that window actually looks better than the original windows on the rest of the house. After seeing his work, we are planning to save up and hire Dave to come replace all our windows. I would highly recommend Dave. He is a true professional, courteous, knowledgeable and definitely a perfectionist.”

Description of work: Replaced old windows

“Energy Windows LLC removed old windows from metal casings and replaced them with high performance, energy efficient windows. Because of the age of the home and limited access to the outside of some windows, the job was challenging. David Udstuen and his crew are experienced professionals and made sure the job was done right! We highly recommend this company.”

– Marla Boulter, 1/2/16


“Wow! I have a house overlooking the Shenandoah River and I wanted 8 large bay windows installed. I wanted to have a fantastic view. I am a very educated shopper. I had 4 different companies out to my home over a 3 week span. All of them were very professional but some were to professional and I felt like I was being sold a product. When David came out to see me from Energy Windows LLC, he did not pressure me, he just educated me on what the best choice for me would be.

I decided to contract David for his sincerity, knowledge of the product and belief that he would perform honestly. Oh, and his price was about $1,000 less expensive.

His crew showed up right on time. David was there the entire time making sure all windows were installed correctly.

I am so happy I chose Energy Windows, LLC.”

– Marshall Wayland, 12/29/15


“I had two prior estimates before contacting Energy Windows LLC. Both bids came in very high, and I was a little unsure if I could afford either of those bids. I shopped around and saw an advertisement by Energy Windows, stating that it had the best price in town. I went ahead and contacted Energy Windows. The owner was very prompt and responsive. He came out right away and gave me a bid. He gave me the most affordable bid and I signed the contract that very night. I appreciate that there is no middle man and the owner himself would be installing the windows. I like that he is a small business owner and he is the direct face of this business. If I had any concerns or questions, I knew I could contact him right away and he was able to reassure me of my concerns and answer my questions. It took about two weeks for the windows to come in and he contacted me ahead of the delivery and scheduled the appointment date. I liked that he asked which day worked best for me. On my install day, he was right on time and explained in detail how he was going to remove the windows and install the replacements. He laid drop cloths down so that he couldn’t track in dirt or mud which I appreciated since I had brand new hardwood floors put in. His attention to detail and the precision he puts into his work is amazing. His workmanship is right on target and at the end of the day, the windows looked gorgeous. Looking from the outside, it definitely showed a lot more character and really stood out. About two weeks after the windows were installed, he contacted us as a courtesy to see how the windows were holding up, and asked if there was anything else we needed. To me, his dedication to his work and his customers is phenomenal. I cannot say enough good things about this company.”
