What is Post Construction Cleaning:

Post construction cleaning is the removal of construction debris, dust, adhesives and paint specks after construction or renovation is completed. A layer of dust is left behind from the sanding of drywall and wood frameworks. This drywall dust and wood remnants are much more abrasive than everyday household dust.

Therefore cleaning new construction windows requires window washers to use the right tools and follow correct protocol as the construction dust can easily scratch glass. If construction dust is rubbed into glass with the wrong cloth, your new windows can have nicked or scratched glass.


According to the CDC, falls are the number one cause of construction-worker fatalities [1]. Safety and fall protection is our top priority. RayAccess front line workers are certified to use the full spectrum of access equipment such as telescopic water fed poles, ladders, man lifts, suspenders scaffolding, swing stages, and industrial rope access 

Garnering the highest safety ratings, our staff is trained and certified in industrial rope access. Rope access is employed all across the world with over 15 million hours of recorded labor. For the oil exploration industry, rope access is the preferred method for inspection, maintenance, and repair. RayAccess is certified at the highest level of level 3 rope access accreditation.

Cleaning Windows After Construction The Professional Way:

Besides having the right window washing supplies and access equipment to safely work at height, a professional window washer completes a multi step process to ensure all post construction windows are dust free and sparkling clean.

  1. Vacuum construction dust from window tracks
  2. Protect floor and surrounding surfaces from dirty water runoff and drips
  3. Pre-wash windows to remove dust and particles that can scratch the glass
  4. Remove paint or adhesive material with glass cleaner, superfine steel wool, and glass scraper (very carefully)
  5. Apply glass cleaner
  6. Wash glass with scrubber
  7. Squeegee
  8. If leftover debris remains, then repeat steps 4 through 7 
  9. Detail edges and corners with dry lint-free cloth

Post Construction Window Cleaning Cost:

The first window cleaning service of a building or house after it’s built is more expensive than routine service. This first window cleaning service commonly referred to as “post-construction” requires a more careful and arduous approach.

Hand cleaning is more effective than cleaning with an extension pole. Post-construction window cleaning also requires additional steps to remove construction dust, paint splatter, and tape.

Frequently Asked Questions:

What is usually included in this service?

Typically, post-construction window cleaning includes removal of stickers, misplaced adhesives, plaster, stucco, tape, paint and other construction materials as well as dirt and dust from window/door glass and frames. Additionally, deep tracks cleaning can be included per Client’s request. Permanent labels (UL, WH, etc.) will not be removed.

Can scraping construction debris scratch glass or frames?

Indeed, improper cleaning techniques and use of worn razor blade scrapers can scratch glass. In our company, every worker is highly skilled and trained in scratch-free construction window cleaning. We use special cleaning solutions to soften adhesives so they can be removed easier, as well as super fine steel wool to minimize use of scraper. When the scraper is used we ensure to use sharp blades, and replace them timely. Scrapping must be done in one direction in a continuous motion. 

Unfortunately, windows get scratched during the transportation and construction process. Our technicians detect these scratches before cleaning, promptly take photos, and let our clients know of the pre-existing damage.

When should I clean windows during my construction project?

The rule of thumb is windows should be cleaned at the very end of a construction project, after all the painting and finish work (including landscaping) is done. However, there are a few exceptions: 

  1. Windows are extremely dirty that cleaning them would potentially create a mess, for example – drips on the finished walls/decor. In this case, it might be better to do the main construction clean up before final finish work, and do regular window cleaning to wash off any remaining dust.
  2. Landscaping might be in the way of putting ladders/equipment to access exterior windows. Again, main clean-up should be done before finalizing the landscaping, followed by regular window washing if it’s needed.
  3. There are suspected scratches on the windows caused by transportation, storing, installation or construction work. The earlier such damages are discovered the easier it’d be to replace the windows using a warranty. If damages are detected, post construction window cleaning is halted.
Can high windows be cleaned from construction debris with long water-fed poles?

No. Construction window washing requires detailed hand cleaning with special products and tools. While water-fed poles is a cost-effective solution for regular and routine window washing for many high windows, they are absolutely ineffective for post-construction projects. RayAccess has special expertise in using lifts, scaffolding and Industrial Rope Access which allow us to safely access and clean hard-to-reach windows from construction debris at any height.

  • I'm really happy with work RayAccess did for us on painting the exterior of Loews atrium. At first, I though it would be a nightmare project because of old paint condition and difficult access to some areas. But it turned out to be a very professional and smooth job! Thank you.

    Rex U. Loews Hotel/ Director of Engineering
  • RayAccess painted our outdoor movie screen on a high-rise building in Downtown LA. With their Rope Access method, they saved us thousands of dollars in bringing a huge lift and blocking almost entire street. The job was done perfectly! Thank you so much!
