"The process started with Mark coming to give us a very professional demonstration of what our sunroom would be like. Very conscientious and friendly experience. Then Mark’s son Marcus came to take official measurements. Another example of the professional and highly competent folks that they employ. I had only email and telephone dealings with Rick Carney but he was always pleasant, helpful and willing to listen to any concerns I might have had. Construction a bit slow getting started due to COVID 19 concerns but when Anthony & Isaiah arrived on Oct 13 to begin work all went well with the reinforcing the deck to withstand the sunroom weight. All that was completed the first week then the rest of the work was performed by Joel and Doug. I was amazed how completely adept they were at making things happen while minimizing the mess I have seen at other construction sites. John Morrison then took over to install the electrics for the room. Although he was an independent contractor, he still exemplified the standards I had become accustomed to. Thank you folks for all and we love the room!"– James R. | Locust Grove, VA | December, 2020 * * * * *

"We have enjoyed our solarium that Patio Enclosures built for over 14 years now! We LOVE IT! It was the best addition we ever made to our home! Ron is outstanding on service when comes to our home to fix a little something here or there! Thank you Patio Enclosures! "– Brad J. | Manassas, VA | December, 2020 * * * * *

"The workmen were very professional and skillful. They took their time and did a great job. We are very pleased with our new porch."– Ellen B. | Alexandria, VA | June, 2020 * * * * *

"The design advice from our salesperson was spot-on. Once the project got started, it progressed quickly and the finished project is beautiful."– Lynne H. | Annandale, VA | June, 2020 * * * * *

"Great job, sunroom looks fantastic!"– Wendy L. | Annandale, VA | May, 2020 * * * * *

"We contacted Patio Enclosures among several other companies to bid on a sunroom. Their representative, Marcus Toms, gave a great presentation, explained completely what they could do for us, gave us a great discount on the cost and we decided on them right away. The work crews they sent were extremely good, punctual, did everything that needed to be done to get the deck prepared and the room built. We had a couple of issues before the final inspection, but in all cases, they handled them to our satisfaction. We now have a beautiful, air conditioned sunroom that we use everyday. We couldn't be more pleased with the efforts and professionalism shown by everyone we came in contact with from the company. If asked, we would highly recommend them to anyone. In the future, my daughter, who just bought a new home, hopes to add a sunroom to her home and intends to use Patio Enclosures. Thanks for a great job."– James B. | Herndon, VA | April, 2020 * * * * *

"The patio enclosure has added beauty to my home. Installation was timely and to my satisfaction."– Stuart A. | Winston, VA | February, 2020 * * * * *

"The salesman was very honest and clear with us about how everything would work from start to finish. The workers also went to very detailed effort to ensure the existing foundation, outlets and carpet were thoroughly protected from the weather, and their work quality was great throughout! Everyone we worked with was always on time, courteous, and professional in every situation including our salesman, scheduler, foreman and workers. Lastly, on top of the impeccable work that was done, the workers were kind enough to help us move in the last piece of furniture with a smile on their faces!"– Scott W. | Alexandria, VA | January, 2020 * * * * *

"Once completed, the work was well done and our sunroom was left clean, as was the area surrounding it. The installers were friendly and professional."– William B. | Warrenton, VA | November 16, 2019 * * * * *

"We're very happy with our new screened-in porch, and the entire process was very smooth. Everyone involved was courteous and professional. The installers, Tony and Ricky, explained the process and kept me informed as to what they were doing and made sure I was involved in any decisions necessary along the way. They made sure I was satisfied with the end results before they cleaned up and left."– Tom P. | Front Royal, VA | November 1, 2019 * * * * *

"My wife and I couldn't be any happier with our new Great Day Improvements patio enclosure. The two-man team that installed it were highly skilled in every aspect. As a double career military and civil service family, we have built many homes. We rank Great Day Improvements as the number one construction firm."– Paul P. | Mclean, VA | October 23,2019 * * * * *

"The design crew were detailed and easy to work with in making some minor adjustments. The building crew was fantastic. Roger (Lead Builder) would describe every aspect in the morning and what was accomplished before he left. He was very detailed orientated and made sure everything was done correctly. He continuously made me feel comfortable with the project. At project end, he quickly took care of some minor items I found to my satisfaction. We were very happy with the end result."– Steven W., Manassas, VA | September 26, 2019 * * * * *

"First of all, the patio roof looks great and is very, very well done! That's the minimum expectation we had, that the job would get done right. But beyond that, it was done professionally -- Roger & Rich were like clockwork each day: on-time and working the entire time. That made the job quicker than we'd expected. They kept the job site in order and at the end of each work day we didn't have to worry about anything being left in the yard, etc. So of the various contracted projects we've done over the years this was one of the most pleasant to deal with!"– Rick G., Fairfax, VA | April 25, 2019 * * * * *

"Installers went above and beyond to take care of a couple of unexpected issues due to the age of the home. Everyone was professional and great to work with!"– Rodney S., Midland, VA | April 9, 2019 * * * * *

"I would like to take this opportunity to thank you and the entire staff of Patio Enclosures in Washington, for all the excellent, professional Service, that has been provided to us, with our Sunroom and Deck project.

"Could not be happier with the work! We LOVE the enclosure and look forward to spending ALL of our time in it!"– Tom C., Palmyra, VA | February 14, 2019 * * * * *

"The design consultant, Mark Toms was patient and was thorough in his demonstration of the product and in helping us to move through the different model options to chose the room that would best serve our needs. He was clear in his explanation of the scheduling process and the timeline, leaving us with a realistic understanding of the service we could expect. The two installation experts, Mr. Joel and Mr. Ebarro, arrived early each day and were professional throughout. Mr. Joel was patient answering on-site questions and addressing concerns. His work was detailed and the installation was completed with very minimum interruption to our property. Best of all, the room was completed ahead of schedule! We now have an addition that compliments the overall design and quality of our home. Thank you for making our vision a reality!"– Linda W., Leesburg, VA | January 17, 2019 * * * * *

"Over-exceeded our expectations! Mark and Melanie were a delight to work with! So helpful, personable and professional. I was pretty nervous about enclosing our much loved screened in room, but now I am over the moon in love with it! Our job ended up being a bit more involved than we hoped, but they were great at making sure things were done right."– Joanne G., Palymyra, VA | January 7, 2019 * * * * *

Once the permit issues were taken care of, construction began and the structure was completed within the time frame estimated subsequently which was end of April 2018.
