Review by in Hyattsville, MD
Project: New Windows
Very very impressed. For anyone that wants a window company that does a top notch job, sells an excellent product, and doesn't want to ever worry about any part of their window installation, this is the company to use in the DC area. For many of you, you probably started out like I did, looking for the best value, generally optimizing for price. The more and more I dug into Wow, the more I realized how horribly wrong things can go with getting the wrong type of window, choosing a mediocre manufacturer, and ending up with a subpar installation. My experience with Wow was none of these things. They sell a very high quality product, the OKNA 700s, gave me a lot of confidence they would fix any issues that arrive.for the next 20 years or more and did a picture perfect installation. From the detail on the caulking and insulation to making sure none of my drywall was damaged, I was incredibly impressed. Are they the cheapest in town? No. But they are the best. If you want to buy windows and not have to worry about the installation, quality of the windows or lifetime issues around the windows... use these guys. Hands down.

Review by in Fairfax Station, VA
I had four sliding glass doors replaced. Most companies were pre-set on the one or two options they would sell me. Windows on Washington (Zach) took the time to measure and discovered all of my doors were a non-standard size by 4" each, which I independently verified (star 1 for WoW). Then they offered several options, to include competitive pricing on a competing bid (star 2 for WoW). Ultimately we "settled" on low maintenance 5-point locking doors with exterior keyed locks, which only WoW offered as an option (star 3 for WoW). For the installation they worked around the unusually rainy season and our schedule to get them installed. We knew we had wood rot in the old door frame, but they (Young Kim and crew) also repaired part of the housing structure at no additional cost (star 4 for WoW). Finally, they offered us 12-months with Zero percent financing (star 5 for WoW). We did have a few issues along the way, but once I communicated with WoW they (Cathy Mejia) were incredibly helpful and worked to make things right... what more could anyone ask for? I WILL BE using them again to replace the front door and a few other items on my fixer upper. I HIGHLY recommended this team!

Review by in Falls Church, VA
Project: New Windows
I got 5 windows installed on the front of my townhouse. Windows on Washington were professional from the start. Greg did a great job showing me their window options and they do use excellent quality windows (I reviewed the windows online myself). The installation went very smoothly, except one of the windows came with the 8x8 grid pattern instead of 6x6; once I noticed the mistake and told the installer, he called the office right away and they ordered the correct one to have it replaced within a few minutes. One thing to note is that the whole process takes a while, since they are custom windows that have to be ordered and made. For me, it took about 2 months total from the consultation through the installation (early July to early September). Perhaps if you order in the winter, the manufacturer would be able to make the windows quicker.

Review by in Ashburn, VA
Project: New Windows - 6 +
We replaced all 23 windows in our town house and 3 doors, 2 of them sliding patio doors. The project was flawlessly executed- from planing to scheduling to installation.even the weather cooperated! Windows were made on time, the crew showed on time and finished ahead of schedule. They were very respectful to our requests, cleaned after themselves and explained in detail all features and how to take care of the new windows. The windows and doors are solid and good quality, we feel the difference already. We highly recommend Windows on Washington !

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.

NOTE: Member service professional information confirmed as described above may change or expire over time; while HomeAdvisor attempts to maintain accurate and up-to-date information, and confirms changes when notified, we cannot guarantee that profile and screening information is accurate. Therefore, we recommend that before working with a service professional you verify that information presented is still current and/or acceptable to you.
