Worst home improvement experience ever. Bought 6 windows and 3 had to be replaced within two years. Took months on end for the replacement windows to be installed not to mention the numerous phone calls I had to make. Save yourself the trouble and buy elsewhere.

Window World of Washington DC (WWDC) installed all of the windows at my home in July 2021. On the same day, I emailed WWDC about their mistakes and Greg P. ensured me that the company would fix the issues. The issues are the following: windows installed improperly, uneven borders/frames, lack of caulking, cold air entering through window frames during the winter, and more. Please see the pictures for proof.
On September 20, 2021, Greg P. stated, "I will get with my team and make sure this is handled properly and as soon as possible" and "We will all help to ensure we get these issues resolved." As of June 8, 2022, the company has yet to fulfill its obligations. I emailed WWDC several times but received no response. One of my favorite quotes from Greg P. is, "I can assure you nobody is avoiding anything." Update: As of 6/24/2022, WWDC sent a reliable person to fix the outstanding issues on the spot. I'm very content.

They are extremely unprofessional, have not contacted us for the delays with our order and installation. The windows were ordered in February and the only communication has been when we have called. On top of that they are rude and impatient when we indicate that the installation has been so delayed. It makes us feel slighted and as though we the customers are a bother to this company! We would very much like to cancel but unfortunately we are stuck.
We are not confident what kind of quality we will see for the product, the installation, and the ensuing service. In fact I would never want to interact with this company. Don't make the mistake of signing up with Window World.

We had 7 floor to ceiling windows installed along with 3 sliding glass doors installed. The product quality and installation is/was outstanding even though supply chain issues delayed delivery by 5 months. However, the sliding glass doors did not come with the ordered screen doors - again "supply chain issues." When we call to inquire about the status of those screen doors we are met with rude customer service - they seem annoyed that we ask about the status.
Then a couple of weeks ago (6 months after the installation) they called to schedule delivery and installation of the screens. Great! But the service technician shows up with only one screen door out of the three we require. We call the store manager and he tells us it's not his fault - supply chain! No communication, no status updates, no customer service. Very disappointed and still waiting.

Don't go to this location. They have a awful customer service and do a poor job with installation. They incorrectly installed our roof siding, and the pieces subsequently fell off during a windstorm. After countless phone calls requesting someone to come back to take a look, WW sent someone to evaluate the damages. He confirmed the siding was installed incorrectly, and that he would put in a report and have a team sent out to resolve. However, the WW office has no recollection of this visit or this report. We're back at square one and are being told to contact our home insurance, since the damage was caused by a windstorm.
It seems the owners of this location have zero logic or deductive reasoning skills. Also seems pretty shady and fraud-like to KNOW you've incorrectly installed something, and refuse to fix it and/or provide the report that your own employees have submitted. Overall - poor management, poor installation skills, poor service. Would not recommend.

Don't expect anything to go as planned with window world. Expect delays. Expect to be ignored. Expect to be re-scheduled. Expect missing items. Expect failure.
