Paul was very helpful and knowledgeable of the Porch Conversions V-4 windows. He answered all of our many questions and walked us through the ordering  and shipping process. The installation process was easy following the provided instructions. We like the ability of having all the windows closed on a cool morning, then easily sliding the windows up or down to allow airflow as the day warms up. They are a nice complement to our sunroom. We are very happy with our purchase.

We absolutely love our Porch Conversions’ V-4 windows from Deck Builder Outlet! We open and close them on a daily basis and like how we can regulate temperatures in our unconditioned space. Even though we had a small problem on our initial order, Paul handled it quickly and very satisfactorily. We highly recommend these units from Deck Builder Outlet!

We love our windows from Deck Builder Outlet. They allow us to spend a lot more time on our deck. It is a 3-season porch now. The windows keep out the weather when completely closed but are also easy to open. There are many options for having them opened at different levels. Deck Builder Outlet’s  service was excellent. They walked us through the measuring of what we needed. The ordering was easy and delivery was smooth. We have recommended our windows and Deck Builder Outlet to all of our neighbors, Very happy customers!

We had a covered deck on the back of our house.  We framed it in and ordered Porch Conversion windows from Deck Builder Outlet.  Everyone was great to work with!  They made our windows to our exact measurements and they fit perfectly!  We love our new 3 season room!  Highly recommend Deck Builder Outlet!

I want to take this opportunity to tell those who are looking for porch windows to take a good, hard, look at Deck Builder Outlet.  Our experience with them was a very positive one which occurred when we needed to replace a few vinyl film stack window sections.  Even though our order had to be a very small one for their company, we were treated with courtesy and promptness and I don't know how they could have been any better.

We absolutely love our windows and they were exactly what we were looking for. We started off just wanting a screened in gazebo but after discovering your windows what we ended up with was more than we ever imagined! It is now affectionately called the "tiny house". We can hang out, eat, watch tv while still enjoying the outdoors.  We have been through two hot summers, two cold OH winters and these windows still look brand new. The whole process was so easy and Paul was great. Since we were building the structure from the ground up, he made sure we did it in the right order. Thank you for making such an affordable, fantastic product! We could not be happier with our tiny house and it is all because of your company!

I remain thrilled with my V-4 windows from Deck Builder Outlet. Sizing my existing screen openings was easy, and Paul was generous with his time setting me up for success. Several years into using the V-4 windows, and they operate and look brand new. Big thanks to Paul and his team! I’m a very happy customer.

I had researched a number of products to transform our back porch into a space with a more finished look that would allow us to use the area more often in changing weather conditions.  I was lucky to come across Deck Builder Outlet and quickly received information on the product, competitive pricing, and ordering and installation advice. We could not have been happier with the customer service that we received right through to delivery and would highly recommend both the company and the product to anyone looking to purchase. Our windows and doors were installed 9 months ago, have worked flawlessly, and continue to to receive really great comments from our friends and family when visiting.  Do not hesitate if you are in the market to beautify a porch or four season room in your home.

I love my new screen room porch and how the window configuration allows me to control as much or as little outside air that I want!

I will be putting the same system in my Lake home very soon.

I want to thank Paul at Deck Builder Outlet, for all of his help and advice with my porch conversion project.  We purchased our home with a screened porch several years ago. After a couple of winters, rain and wind, we could see all of the dirt and standing water in the porch and knew we had to do something.

I did a lot of research on porch window systems and determined the Porch Conversions Stacking Vinyl Windows was what I was looking for. Regarding the product, I wanted the spring side-loaded window design of the Porch Conversions system versus other systems that used pivot pins to get the windows out.

I contacted Deck Builder Outlet and spoke with Paul. He was very knowledgeable and gave me a good price. Additionally, he came up with a great solution for my door that needed to swing into the porch.

We love the look of the windows and the ease of operation. It held up to 50+ mile gusts and kept the room rain free and clean.

I highly recommend, if you are in the market for porch windows, to speak with Paul and Deck Builder Outlet.

I purchased Porch Conversions V-4 stacking vinyl window/screen panels from Deck Builder Outlet for a covered porch that I was building as part of an addition to my lake home and I am extremely happy with the results.  From the first phone call to Deck Builder Outlet to the completion of the project, things went very smoothly.  The ordering process was simple. I talked to a real person, Paul, on the phone.  Paul walked me through the entire measurement process and explained my options for colors and screen fabrics.  Once ordered, he gave me an expected delivery window and the products arrived on time, as ordered, and free of damage.  While this may seem normal, given my experience with other projects like this, I can assure you that it was above and beyond what I have come to expect from vendors in the construction business.

As for the product, each section comes fully finished with high strength screening and tough, heavy gauge vinyl windows with aluminum frames in plastic tracks.  Each window panel (four per opening) is removable for easy cleaning.  The dimensions were exactly as ordered.  The fit and finish is clean and tight, and the windows slide up and down easily.  I am so glad I made the decision to add the vinyl windows.  They literally turned a simple screen porch into a 3-season sun room!  What was almost an afterthought as part of this project has turned out to be my favorite space in the whole house.

We are now able to enjoy the extra space since we converted our screen porch to a 3-season room thanks to Porch Conversions V-4 windows. The quality of the materials is excellent and the V-4 windows stop the rain from entering the space which was a problem prior to the conversion. The windows are easy to remove and clean. The purchasing experience was no hassle with great customer service. I recommend this product to anyone looking to convert a screen porch for additional living space.

First of all I want to say we LOVE our Deck Builder Outlet vinyl windows and you will NOT go wrong ordering these. We wanted our back porch to be open for a view, but we also wanted to let as much air in as possible during the warmer months. These windows can be lifted up from the bottom, down from the top, or completely removed with screens left up, and they are also easy to clean. Paul was a delight to deal with from day 1.
We needed a darker tint for 1 area because of evening sun, what a wise choice that was with the help of Paul giving advice of what they have to offer. Windows came packed perfect and delivered in the time frame expected.
Family and friends have seen these, & also closed in their back porches as well with these windows.
Thanks Deck Builder Outlet for the GREAT idea!

I can’t even begin to explain how much I am enjoying the windows. As you can see from the dog bed on the floor, my Great Dane also is loving it. One of the true advantages is, no more covering everything up because of pollen season.
Working with Deck Builder Outlet was a great experience. Since I was taking on this project myself, I had a million questions. Paul was more than patient with me. He explained everything I needed to know down to the smallest detail. At one point I was somewhat overwhelmed and contacted 2 different companies for a quote. I found out real fast that Paul explained things to me that the other 2 companies didn’t even mention. I was not comfortable with what they said they would do and their price wasn’t even close to what I paid to Deck Builder Outlet.
You cannot go wrong with this product and no one will treat you better than Paul.

I am a self employed General Contractor in Upper Michigan. I installed this door and these windows in Harbor Springs. The Homeowner loves these windows because they are the perfect solution to enclose a patio or porch. They keep the elements out and are easy to open and close. When fully opened, 75% is open to the breeze. Deck Builder Outlet goes way beyond industry standards when it comes to customer service.

We could not be happier with our V4 conversion windows. Everyone comments on how nice they are and how they wished they would have installed them on their outdoor space. They single handedly turned what would have been a 2-1/2 season room (midwest) into an almost 4 season room. They arrived in a timely manner and were packaged perfectly to protect them. The cost was extremely reasonable for what we received and the install was easy. I highly recommend them.
