“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. We only had one hiccup and that was someone measured the garage window wrong. It was listed as the same size as the lower bathroom window but it was larger, I know 3 of us measured that window and I know it measured larger but somehow it came in too small. Since it was the garage side window and not that critical they resized the opening and put it in anyway, it looks real good and you have to look close to see it’s smaller. 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.”

“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.”

“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.”

“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.”

“We are pleased to report that we have just completed the project of Capping of the Facial wood of our property and Energy efficient Vinyl Windows with Window World of D.C. and are very pleased to recommend them.

We have owned the property since 1982, and bought it from Battlefield Builders. During these years, we have seen the deterioration and decay in the wood and peeling of the paints, as a result we use to get the summons from our HOA to fix the problem.

To meet the requirements of the HOA, it costs in excess of $2500 to $2800 every few years and this cost is increasing as the cost of labor and material increases year after year. So we took decision to get the help of Window World of D.C.

We found their estimate was very competitive and very reasonable and cost saving in the long run. Overall, Window World product and labor are guaranteed for the lifetime you own the house. Their total team is professional, excellent in their workmanship, and is backed by the factory. Also their products are energy efficient, and meet the present NFRC standards.

If you think you are going thru a similar problem like us, we suggest you contact Window World. Their phone number is (703) 378-7999 and they serve the entire Washington D.C. area. Window World has a showcase of all their products, vinyl windows, sidings, gutters, exterior doors, and a variety of other quality products.

I suggest calling them, they have dedicated staff to provide and demonstrate their product and provide you with a competitive cost estimate with quality of product, workmanship, and factory installation with excellent customer service.

You may refer our name and can vsit and stop by our property to see their excellent product and workmanship backed by superior customer service. Thank you!”
