Apex Window Cleaning

Apex Window Cleaning was established in 2000 and is a WBE Certified Enterprise. We specialize in commercial and high-rise services, including window cleaning, restorative caulking and weatherproofing, and pressure washing. With over 20 years experience in the industry, we have handled some incredibly challenging work in equally challenging conditions. Although we focus most of our business in East Tennessee, we have also proudly served Middle and West Tennessee, Eastern Kentucky, North and South Carolina and Western Virginia. Due to our rigorous safety procedures, Apex has had the pleasure of completing jobs for ORNL and Y-12, TVA in Knoxville and Chattanooga, and the Public Building Authority of Knoxville.

Commercial Window Cleaning

If you have a one story or a twenty-story building, Apex will complete the task in the most timely and professional manner possible.  We take several things into consideration including:



The most obvious concern when taking on a large-scale building is safety procedures.  Not only do we have to be concerned about our own employees’ safety but also for the safety of pedestrians entering and exiting the property.



We realize that your time is as precious as ours and are more than willing to work around your schedule.  Whether it is an office building, a residence, or a retail space, we will be respectful of you and your tenants so as to create as little disturbance as possible.



With more construction leaning towards LEED Certification, Apex will gladly rise to the challenge and meet these requirements.  We pride ourselves on performing our job in the most eco-friendly way possible with little to no use of toxic chemicals.

Free First Estimate

We would love to provide you with a free no hassle estimate. Estimates usually take us 2-3 business days to process.

If you would like an estimate please provide us with your building specifications, the type of work you would like done (i.e. clean windows inside only, outside only, or in/out), and you will receive a no cost/obligation estimate.

For your convenience we are also able to schedule cleaning for you on an ongoing basis whether it is monthly, bimonthly, quarterly, or semi annually.

We will provide window cleaning estimates in the entire East Tennessee Area, parts of North and South Carolina.

See What Others Are Saying About Apex!

  • Excellent performance from the team at Apex. They arrived for an estimate within days of my initial request, and performed the job on our five story Historic renovation property within a week. We received estimates from others, none offering the thorough hand cleaning our windows required or the fantastic customer service.  Beth Turner

    Choose Apex for superior results!
  • Apex Window Service is a step ahead of the competition.  Professional, diligent, and personable, they do great work at a reasonable price.  Their people are first class and leave nothing undone.  To say that I was impressed is an understatement.  They will have my business from now on.  Do yourself a favor and select these folks for the best window cleaning service you will ever have.

  • I love this group of guys and gals. They’re easy to work with and will always get the job done in a professional and timely manner. I’d recommend to anyone!! Benjamin Miller

    Great work and customer service!
  • We in the Public Building Authority of Knox County and the City of Knoxville have worked alongside this organization for all of the 10 years mentioned in their review and we can stand by the APEX claim of job(s) well done with safety always being job one. The years of service have been accident free with a level of customer service second to none. Anything whether it is the window cleaning of interior/exterior glass or even the pressure cleaning of one of our LEED certified facilities has always been with complete customer satisfaction above and beyond our expectations. This level of customer satisfaction is a rarity this day and time. We appreciate the entire APEX team and their hard work. We stand behind them in their continued success and safety on each and every job they take on. Highly recommended! Darrell Shepard

    Safety First
  • They did a terrific job on the Mary Boyce Temple House we recently finished restoring on Henley Street. it took well over seven years to put that mess of a house back together so the windows were horribly dirty. I came home to sparkling windows, washed with great respect to our home. I highly recommend Apex. Brian Pittman

    Great Residential Work
  • My husband and I are new to city life, having just moved into our first downtown dwelling. Apex takes care of our beautiful windows in a professional and courteous manner, leaving them sparkling! Thank you Apex for keeping our view of this beautiful city crystal clear! Stephanie Smith

    Great people, great job!
  • We brought Apex here to Columbia, SC to pressure wash and clean the windows of our 7 story property. Their performance surpassed our previous work and their customer service/hospitality was unmatched. We will continue to use Apex for all of our future work and will likely expand their services to our numerous properties. Very pleased!!!! Dwight Dooley
