“Hi Anthony,
Just a short note to let you know I have new windows!! The guys got here this morning and worked like they were on fire. They had all 22 windows out and the new ones in their place in 2½ hours. I couldn’t believe it, there were only 3 of them and they couldn’t have been nicer and more professional. It didn’t seem to bother them having me hanging around watching them work, I was amazed at how efficient they worked together. I guess installing the windows was the easy part because it took them the rest of the time (7½ hrs) capping and caulking. They completed the entire job in 10 hours which was unbelievable to me it just goes to show you that “you can’t beat a man at his own trade”. Thank you so much for everything I am so happy I chose Window World for my windows, it was your superb salesmanship that did it. Window World is a top notch company and I will tell everyone how satisfied I am. Take care and I hope I never have to call you with a problem.”

“Last winter was bad, my mom and I froze all winter. We needed new windows but could not afford them. A friend told us about window world and the guys were here today. They worked very fast, very nicely, very professionally. So polite and cleaned up nice afterwards. Thank you window world for saving our lives.”

Mark Hayes


“Nelson, you are a man of your word. The installers came yesterday and finished the job the same day. The installation was probably the very best experience I have ever had with a home improvement contractor, all the way from your initial visit to the finished product. I would be glad to offer a recommendation for you and Window World. Everything was very professional and straight forward. Except for the new windows, which are great, you could not tell anyone had done any work at all. All trash, dirt, etc. was cleaned up, inside and out.

Thanks for all your hard work and professionalism.”

“My wife and I recently purchased seventeen (17) of your double hung windows for our home. Cliff Claggett, your salesperson, sat down with my wife and thoroughly explained the benefits of the windows and the cost thereof. She was sold. His friendly relaxed demeanor was a pleasant change from how most home improvement contractors are.

Now that the windows are in, I am sold on them too. No drafts or cold spots any more, not to mention the house is much quieter.

However, I would be remiss if I did not mention something to you about the installation crew you sent to our house last Saturday. The crew of six (6) was supervised by a Rigoberto “Rigo” Castillo. They showed up exactly on time and went right to work without taking any breaks until the job was complete. They did such a beautiful job installing the windows and cleaning up after themselves, a half hour later you would never have know they were there.

In fact, after the installation was done, Rigo walked us around, demonstrated all the features of the windows, and reminded us that should we ever have any problems with the windows as long as we are in the house, to just let Window World know and you will take care of it.

It is nice to know that a company like yours and a crew like Rigo’s still exists today. A big thank you from my wife and for a pleasurable experience and great product.”

Jonathan B, Washington D.C.


“Thanks so much for working to get me my windows so quickly. The crew came out Saturday and installed them, giving me over a week before my tenants move in. It’s so nice to have that crossed off my list. Thanks for making it happen.”

Basla, Washington D.C.

Dora M, Washington D.C.

“Extremely satisfied with the work and the professionalism of the window installers.”

Ben B, Washington D.C.


“I would like to commend Window World for such a fine job installing the windows at my home. It was truly one of the best investments I have made over the years I’ve been here. The installers were professional and did an outstanding job — the windows look great. Your explanation of the process and the quality of the windows was superb. Since installing the windows I have seen a drastic change in the climate in my home. I set my thermostat and the temperature in my home does not vary regardless of the temperature outside. We are so very pleased — should have done it a lot sooner.”

Vince P, Mitchellville, MD

“We want to personally thank Arthur Simons for all of his help last night. After he provided us with the price quote for our new windows, we noticed our family room was taking in water from all of the torrential rain the last few days.

Arthur, without hesitation, insisted on helping anyway he could and even offered to help move furniture. We thanked him but told him it wasn’t necessary. He again insisted. He helped my husband bail the standing water in our flower garden, which is a cement casing in the front of house and helped re-position the down spouts away from the garden in order to redirect the water away from the house. He and my husband were completely soaked from head to toe as it was still raining while they were working.

Arthur is an amazing young man and Window World should be honored to have him as one of their employees. He went out of his way to help us and didn’t even think twice before offering. He is truly one employee any business would be blessed to have on their team. He deserves to be acknowledged for unbelievable kindness and thoughtfulness.”

“Excellent group that installed the windows. I liked that Anthony came by to see how the job was going. Great group of people!.”

Peggy Logsdon


“Your guys (Antonio and his group) did a tremendous job replacing the old window and installing the new garden window last Friday. It is so much sturdier than the previous window and it looks wonderful. It is larger and has more direct sunlight. We appreciate all the help in ordering. As usual, you all did a super job. Thank you!”

Fran Mooney


“Dear Window World,
We are very happy with our new windows (6 bedroom windows, installed 6/12/10 and a bay window, installed 10/23/10). Your salesman, Mike Carlucci, was professional and courteous; the installers, as well, were efficient and professional. (When our bay windows proved to have been mis-measured, the installers were able to remake the window so that it fit perfectly, and it looks great!) Thanks so much for doing a terrific job! Yours truly.”
Thomas Phillips & Susanna Garland

“Very professional company. The windows are beautiful and the installer, Danny, did a perfect job. He was knowledgeable and everything was cleaned up when he was done. I would highly recommend Window World and would request Danny as your installer. We are very happy with the results.”
Kathy W.


“We are very pleased with the installation and with the quality of our picture windows. It is phenomenal how the E glass does not allow the heat of the sun to penetrate into our home. Our AC works far more efficient than in the past. We recommend Window World and the Rodney McVey installation team!”
Wanell J.


“We have only had our new Windows for a day but can already see the difference in ease of use. Window World also did a fantastic job with the wrapping around the decorative stuff that was around the windows. We are very pleased with the workmanship and how professional the workers was.”
Jeff B.


“We replaced an entire home with Casement Windows. The salesman, Dustin, was responsive from start to finish. The men who did the installation, 5 full days worth of work, were professional and hard working. My home looks beautiful.”
Lynn S.


“As a Realtor, I have used Window World for numerous projects. This was the best crew you have ever sent for one of my installations. I would like this crew for any of my future jobs. Thanks!”
Jackson M.


“I needed new windows for my recently purchased home, so I called around and got a few estimates. One of the companies I called was Window World of DC. Window World sent an estimator by the name of Dustin Swartz to my house. He was on time, friendly, knowledgeable and he really worked hard to make this stressful process as smooth as possible. Highly recommended!”
Eddie S.


“We love the job that they did to our new windows and trim. Dustin, who did our estimate, made us very comfortable in purchasing new windows, giving us some knowledge about what type of windows we are getting. Thank you guys for doing such a great job and giving an affordable price for new windows.”
Melissa P.


“The folks at Window World came exactly on time and were very professional the entire time. They didn’t leave any mess and all the windows were perfectly installed, trim applied, and caulked. I’d recommend them!”

“I can’t say enough positive things about my experience with Window World! I received estimates from 4 different companies and Window World had the best prices and the best warranty. But more importantly, the people I dealt with were terrific! The people make the company a success and this team of people made their company proud!”
