"I replaced two large windows and two sliding glass doors. There were a lot of factors that went into my decision, and now that I've had my windows for about 2 years, I have some additional comments. First, price. Zen windows doesn't advertise, and they're not available in stores like Home Depot and Lowes. They also don't have that annoying high pressure salesman that is constantly leaving notes on your door like Anderson Windows. They don't do those things, which means they don't have to pay for those things, which means those costs aren't rolled into your costs, which means your costs are lower. Zen windows were among the lowest priced of all the ones I explored. Second, value. What is price, without value? Zen runs three different tiers, the top tier being an excellent triple pane window with insulating foam-filled frames, and they were STILL less expensive than competitors. Less than HALF the price of Andersen Windows. They offer a LIFETIME warranty, and free replacement. Someone breaks your window to get in your house? you get a free window. A dog goes through the window? A kid throws a baseball? Crazy sideways hail storm? You get a free window. But it's more than Zen windows. Zen actually sells windows from a large nationwide brand. I think it's "Softlite", but don't quote me. Anyway, their windows actually ALSO have a lifetime warranty through the manufacture. Zen windows goes out of business, but your window fails? You STILL get a free window. Next, my experience. I went with the triple pane windows, because they come with the foam-filled frames and were only like $50 more per window. But I went with the double pane sliding glass doors, because they would have been like $500 more per door. All in all, the new windows and doors are awesome, and I would totally buy them again. I only had three or four complaints or problems. 1-Their installer actually ordered the wrong sliding glass door for one of my applications. Instead of opening from left to right, and having a door in the corner of the bedroom, it would have opened from right to left. The door would have been behind the bed, and you would have had to step over an HVAC grate to use the door. Instead of offering a solution, the installer himself said "Well, is it ok? Can we just leave it?" NO! No you may not. But don't let this story deter you. The owner himself was more than apologetic. He knew that it wasn't ok, and never even hesitated. He rush-ordered the correct door, and knocked $50 off the total price. In the end, no issue. 2-SUPER tight seals. One of my sliding glass doors (not the one noted above) has a super tight seal. So much so that, when you're opening it, it doesn't open smoothly. About halfway, it hits extra friction and will get stuck. Then you have to give it extra oomph to open or close it. They said that it would loosen up over time, but 2 years later, it's still the same. This is both a good thing (great seals, great weather resistance) and a bad thing (difficult to use) so it speaks in both directions here. 3-mm off in size. One window is just a HAIR too big. I mean really, like 1-2 mm too wide. When you close both sides, the mechanism that locks the window doesn't line up perfectly, so it can be difficult to latch. It almost takes two people: one to pull with all their strength, the other to push the other window and close the latch. Almost. I'm exaggerating a little, but it's still an issue. 4-Cracked drywall. When the installation was done, there was a tiny crack about an inch long in the drywall over one installation. I was able to seal it with a couple coats of paint, so it's kind of another non-issue, but one I wanted to point out. These are the reasons I gave them a "B" for quality, but everything else is "A+" quality, and I recommend them to all of my friends."

"It took a little time, but once the windows were finished with trim - they turned out looking GREAT. I purchased 6 Vinylmax windows for my townhouse to replace 20 year old rickety windows that needed replacement BAD. These vinyl windows are white and they did a really nice white trim that looks very clean and bright on the inside. Windows work as expected and they gave me a quick reminder of how they come out for cleaning. Noticeable difference in temperature in the house. They were a nice group of guys, worked hard and communicated potential issues with how my wood blinds would fit once they added the interior trim, which I appreciated because it was something I hadn't thought of. The downside of the installation was the amount of time it took. Sales person said they could get it all done in one day, but it did end up being 2 (separate) days to get it all done. For reference, it took 10 hours for a 3 man crew to take out and install 6 new windows. They were here until 8p and then realized that they were sent with the wrong size trim, so would have to come back to finish that (which was fine by me because by 8p, I'd like to wind down without anymore banging/people in the house). Also, one of the windows were opposite of what I requested (needed window to slide left to right, they installed right to left but recognized the error and would fix with the 2nd visit). The 2nd visit was a 2 man crew and took about 9 hours to replace the one window and do the trim for all 6 windows. For some reason it felt like they were here forever, but maybe that's just how it is. My only advice to future customers is to consider that the project might take more time than originally quoted. Also, if you have hanging wood blinds MAKE SURE you discuss proper measurements for the trim because for a minute there, they were suggesting that I consider foregoing the blinds or moving the brackets forward to account for the trim, which would have made the positioning of the blinds kinda weird. Also...take measures into your own hands with protecting wood floors. They laid some covering down but there were a handful of scratches when they were done. Also some wall scuffs (to be expected) and some dry wall patches that they did are not the best patching jobs so expect to touch those up."

"HIGHLY RECOMMEND. Josh quickly found the source of a window leak that other specialists missed. This saved replacing flashing and windows in an attempt to stop the water leak. He also expertly replaced the inside trim around my window. It looks just like it should. I'm very grateful for the ways Josh went above and beyond. Josh seems to be doing what he does Best, being a secretary is not that, have patients and follow up. It's woth the effort."

"Perfect. My dog ran through the screen and stretched it. I called and filled out service request. They called back and we scheduled the repair (service). Got a call today and they were here within 45 minutes. Quoted me a price (more than fair). They replaced the screen and it works perfectly. Really appreciate the professional team.Steve and Todd were the BEST."

"Our old 1890's house had some original wood windows in very bad shape. Nick at 5 seasons windows was great to work with, and was able to get the ball rolling with some basic phone pictures and general measurements. 5 seasons came out and custom measured and did a great job installing 5 fiberglass windows that work great and should last another 130 years. We did have one item to resolve when one of the window tints didn't match, but Nick was very responsive and helped us get it replaced in a timely manner. Overall a great experience, and we will definitely work with them again and am hoping they can help us with window/door replacement on another property as well."

FAQs for new windows service projects in Denver, CO

Yes, bay windows add value to a home. They enhance the property by expanding the interior space and flooding rooms with natural light. Their unique three-panel design creates a stunning focal point that elevates curb appeal and modernizes living areas. This architectural detail increases both functional space and visual appeal, directly contributing to higher home resale value.

Yes, all window types have the potential to become part of a bay window configuration when modified correctly. The transformation involves reconfiguring standard windows into a multi-panel design that features a larger central window flanked by smaller ones. This process requires precise professional planning and custom framing to ensure durability, visual balance, and structural integrity.

Bay windows typically consist of three glass panels extending beyond the home's exterior walls, with a larger center panel flanked by two smaller ones. In contrast, bow windows are composed of four to six equally sized glass panels that create a gentle curve and do not extend as far from the exterior walls.

Bay windows cost more than standard windows because their expansive, multi-panel design requires additional materials and skilled labor. Their construction involves extra glass, specialized frame components that extend outward, and complex operating mechanisms. These technical demands necessitate precise engineering and multiple expert installations, thereby significantly increasing both material and labor expenses.

Bay windows cost three times more than standard double-hung windows because their design requires extra panels, expanded framing, and a more complex installation process. The advanced construction method increases material consumption and demands comprehensive expertise, while specialized window treatments further elevate expenses. This all results in a significant difference in overall project cost.
