2375 S Downing St, Denver“If you're looking for window installation, then I highly recommend that you don't look past 303 Windows. We moved into a house with 30 year old windows, and knew they needed to be redone. We contacted three other companies, each of which spent at least two hours walking through the house, measuring everything, and inspecting every detail, only to sit us down afterward and present outrageously high quotes, with added pressure to buy right away, and offering discounts if we did x, y, or z.
After reading great reviews about 303 Windows, I decided to contact them. Honestly, the reviews undersold how great they are. Jay came out and completed the entire walkthrough in about 20 minutes. He immediately pointed out all the issues the other companies had mentioned, and then some. You can tell he truly knows windows. His quote was less than half of the national brand we had talked to, and much less than the other two companies. He even mentioned our problem windows, that no other company had bothered to note, because they were high living room windows, that couldn't be accessed without a ladder. He also mentioned that we could save some money by not having grids on the windows. None of the companies we spoke with even mentioned that. He didn't try to push us into signing that day or up sell, or anything that made us feel like we had to buy right away. Jay was very patient with all of our questions and made us feel heard. He said no job was too small for them, and we could do a few windows at a time. Given how great his quote was, we decided to get everything done at once.
Jay's sons and crew handled the window installations, and they were fantastic. They finished almost 30 windows in two days. They also fixed some of our broken window sills, window trims that had rotted over time, and repainted everything. They were very considerate, and cleaned up after themselves. Jake and Max were especially great. They were friendly, professional, and clear about the few minor issues that came up, while patiently answering all of our questions. I've recommended 303 Windows to our realtor, neighbors, and will 100% be using them in the future if we ever have any window issues.
Even if you need to fix only a window or two, contact Jay. You will not be disappointed. Thank you guys for making our house a little more beautiful!“

Dan Howard, Jordyn Foos and Reese Graves are the best! They worked directly with our insurance company and did a great job of fighting for what we needed.

The service was Absolutely terrific, from the 1st pitch to single day installation, including the removal and replacement of a bay window,the whole process was really smooth. Really love the new windows!!“

12150 W 44th Ave Unit 104, Wheat Ridge“The crew just left and I couldn't be more pleased with the experience. There was a crew of 5 men so everything went quickly and they were done in two days . They laid down tarps all around the house before starting and meticulously cleaned up afterwards. Troy treated us like we were friends not just customers. He guided us through the whole process with the insurance company always quick to answer any questions we had. If you need new shingles you won't find a better company to work with.“

950 W Evans Ave, Denver“This was such a wonderful experience. I found window purchasing to be way more stressful mainly because I got many quotes from multiple large vendors and they were insane. Not only that, but the sales people were pushy and would not assist in helping with information that I would ask about. Gravinas was the opposite. They listened, cared, and were so great installing seven windows in one day for a great price and value. The entire process I just felt really good about working with them. Even the owner called and asked how the process went. If you are in the front range, use this local, wonderful company“

1255 S Kalamath St, Denver“Frank Veiga was an absolute pleasure to work with when Accurate America was replacing my roof. His communication throughout the whole process was top notch, I never felt like I didn’t know what was going on. All of the actual work on my roof was done when I was out of town, and it was so smooth and simple that I almost forgot I was working with both Accurate America and my insurance company to get my ENTIRE roof replaced.
In addition to the communication, the pricing was extremely fair. I never once felt like I was working with a shady company. I even admitted to Frank that I’m a sucker at price negotiations, and not once did him or his team try to take advantage of that. We agreed on my only out of pocket expense being my deductible, so long as I didn’t have any additional work done, and that was that. I didn’t need to prepare for a negotiation or anything. It was as simple as signing a few documents after going over the plan.
Incredible job, I wish every company could be like this!“

4251 Kipling St #190, Wheat Ridge“I spent a lot of time researching and shopping around with all the local options before making a decision. I’m picky—I know what I want and expect excellence from the people I hire. Unfortunately, that often leads to disappointment when contractors overpromise and underdeliver. Thankfully, none of that happened with DMD, and I’m so glad I chose them!
Fred and his team were fantastic. Their pricing was significantly better than what Renewal by Andersen quoted me for the exact same products, and their craftsmanship exceeded my expectations. My new front door is absolutely stunning, the new sliding glass door is both beautiful and functional, and the bathroom window looks amazing.
While it took some time for the products to arrive, Fred’s team completed the installation in half a day—and they did it right. The quality of work, combined with prices the competition can’t match, left me beyond impressed. Out of all the house projects I’ve tackled, DMD has been my favorite to work with. When I'm ready to redo my upstairs windows, I won't hesitate to choose DMD.
Stop searching and hire DMD. They’re the real deal.“

7000 S Yosemite St Ste 285, Centennial“David and the team at 5280 provided exceptional end-to-end service for our new front door installation. From the outset, David impressed us with his promptness in providing a quote and his ability to succinctly answer our questions. The measurement process and order placement were handled efficiently. Notably, 5280 offered more competitive pricing compared to two other companies we contacted, and their availability was significantly better. While there was a minor hiccup in scheduling the installation date, the subcontractor they assigned for the job proved to be efficient, courteous, and fast, delivering great results. Our overall experience was positive. Based on their competitive pricing, excellent service, and quality work, I would definitely recommend 5280 for anyone looking to update their home's exterior.“

National Home Improvement has all of our window, door, siding, and roofing business.“
“I will never order windows or doors any other way. Zen has figured out how to make a painful, time consuming and annoying process easy and painless.
I had estimates from five of the most well known window replacement companies in Colorado. All local companies who are running their business like it is still the 1980s.
They claim the estimate will not take two hours, but it is close. They all did the same thing. Set up a time to visit for an estimate. Come and take initial measurements, spend forever filling out their form, discuss the process (which would require another visit for measurements), sell me on the window brand and how good they are, etc.
Each of the visits were nice guys but the prices were all over the place. Thousands of dollars difference for the same job.
I found Zen online, provided my measurements and they had an estimate to me almost the same day, for a much more reasonable price. When I confirmed I wanted to move forward, they scheduled a person to make precise measurements within one or two days and placed my order immediately.
The other main issues was the timing. No one could even come close to getting me my windows and door as fast as Zen. Zen estimated 4-5 weeks. Everyone else was 8-12 weeks!!
Well, sure enough, not only did the windows and door show up in that time frame, they were also installed.
The communication was great. Luke and Misty kept me informed the entire time, from order, to shipment, to installation. The installation team showed up, got to work, showed me how to operate the new windows and door and cleaned up when they were done.
Something else to keep in mind. All the other companies wanted a down payment. Zen took $0 until the job was complete. I felt we had nothing to lose.
Zen also sends a payment link. Everything is done online, safe and secure. Other companies could only do a paper contract and one only accepted a check. If I wanted to pay by credit card, there was a fee and they had to write down my credit card information to take back and run at the office. No thank you.
The quality of my windows and door are amazing.
So glad we chose Zen and I will definitely use them again.“

2200 S Valley Hwy, Denver“If you need a company to do repairs on an insurance claim this is the company you should use. I used Advanced Exteriors for two of my properties in Colorado when they were damaged by hail. They did all of the repairs in a timely manner and in my case they replaced the roof and repainted both properties. What they quoted me was correct and I only had to pay the deductible. In some cases there was some money left over to do some additional repairs. Their office was always available and returned my calls in a timely manner. This company was recommended by my property manager in Colorado that manages four of my properties. This was an indication to me that they had a history with this company and that they were reliable which in fact they were. They communicated with the appraisers as well as those who did the work and the tenants since I was in California and was unable to be there personally.
Again I highly recommend their services!“

“We live in a mid-century ranch and have windows with aluminum frames. If you know, you know...they are hard, if not impossible, to repair. Luckily, the Window Doctor came through for us. We also had them replace the glass in a sliding patio door. Mike was great--very straightforward; and we thought the pricing was very reasonable.“
