Windows On Washington - Sterling, Virginia

IVAN L

We recently had new windows installed in our home, and we couldn’t be happier with the results! From our initial consultation with Jay through the installation by Joon and his team, the entire process was seamless and professional. The team was punctual, courteous, and incredibly skilled.

The quality of the windows is outstanding. Not only do they look fantastic, but they have also significantly improved the insulation, making it more energy-efficient. The crew left our home spotless, taking care to clean up thoroughly after the job was done.

The installation was completed on time and within budget, with no hidden costs or surprises. Out of all the quotes we received from various vendors, Windows On Washington offered the best value for the high quality provided.

We highly recommend them to anyone in need of window installation. Thank you for a job well done!

This was a wonderful experience from start to finish. The sales representative who came to our house was very polite and profession- we discussed the different options, and found a plan we liked. The process took several weeks as the windows were being built and the communication with the company during this time was always very clear. Finally the day of the installation came, and that took went extremely well. They put the windows in extremely fast, but spent several hours sealing everything and ensuring that they looked perfect on the inside and out.

Great experience with WoW! The installation went smoothly and was done quickly. The crew did an amazing job and the windows and doors just look fantastic! So glad I used WoW and will definitely use them again in the future. A word of appreciation to Plamen who was extremely nice and attentive explaining all the steps an ensuring everything went well. He also did an amazing job on installing the new front door on a not so easy install.

I’m reviewing WoW for the second time. The first review was for their replacement windows, which was an absolutely flawless experience! Their windows are tops & have performed perfectly ever since. I continue to highly recommend them for replacement windows.

Because of our superb experience the first time ‘round we contracted with them via their most excellent salesman Brandon Shonebarger for a new entry door and storm door.

This time ‘round there were problems from the installation on. I won’t give a blow by blow here as it’s too long & too much. Suffice it to say that the repairs took as long to complete as the initial order time line & required multiple trips & two different repair people!!

I need to give a shout out to the second repair man - Plamen - he was actually the original installer until the main installer guy showed up & basically took over). Plamen spent close to 3 hours making the needed adjustments & repairs to make sure that the entry door & storm door worked properly. He patiently explained why one of the multiple issues could not be solved (due to physics, but which I think the industry could easily solve). Plamen worked his butt off, was professional, courteous, conscientious, & the best part of the whole experience.

I cannot recommend WoW for replacement entry doors & storm doors, with the same level of enthusiasm that I can for replacement windows. That’s too bad.

Dealing with Tanya & Gretchen at the office was also a pleasure. Thank you ladies!

In the end I was able to work everything out with the owner Eric Novotny to my satisfaction.

Installed triple pane Okna windows and replaced a couple French doors in home. Process was super easy from beginning to end. Windows on Washington are very professional, with high quality products, and overall customer service was excellent with thorough communication throughout every step and highly recommended installers that took excellent care of my home and property and high quality installation process. Very pleased. Highly recommend. Only one minor painting repair required afterwards throughout entire home and made best effort to clean up everything after complete and ensure I understood how to operate windows and doors. Happy with the outcome. And as a bonus, it’s much quieter inside the home from regular street traffic so noise reduction is notable. And so far the temperature control throughout all levels is noticeably more even throughout home with very cold outdoor temperatures. Thanks again.

I contacted WOW to replace my windows and can't say enough about their customer service, workmanship, and professionalism. Greg was very knowledgeable and easy to work with. Installation and cleanup went smoothly, and the windows look great! This is a top-notch company, from sales, to backend office and production, so kudos to the owner for running a tight ship. I’ve owned a few homes and contract most of my work out and can honestly say they are by far one of the best companies I’ve hired to make home improvements. I highly recommend them! Great job!

We had a great experience with Windows on Washington, start to finish. The company is different from so many window installers - the sales process was easy and comfortable (no high-pressure sales tactics) - our sales rep Brandon was patient with us, answered all of our questions and made us comfortable with making our final choices. We saw so many other 5-star reviews for WoW, and they proved to be true. The installation team was extremely professional, and the Okna windows we ended up installing are beautiful, maintaining the high-end look of the previously installed wood windows - just at a far more efficient level. Project was completed on time and on budget. WoW was a great choice for us, and we'll gladly recommend them to family and friends!

Communication was great from the beginning, which I appreciated. The rep who came to my house for an estimate was very thorough and low key. Joon did a fantastic job with the installation of my new picture window, paying attention to details, and leaving everything neat and clean. I am glad I choose Windows on Washington.
