Post Construction Power Washing in St. Charles, MO. Roofing Tar Removal Project.

At Exterior Cleaning Solutions STL, we recently completed a post-construction clean-up project in St. Charles, MO, where our team tackled some tough tar stains left behind after a recent roofing project. Construction debris and residue are common, but tar is especially stubborn — and can seriously detract from your property’s appearance if left untreated. This was brought to our attention by one of our trusted roofing contractors.

For this project, we used our soft washing system, which combines low-pressure water and specialized cleaning solutions to safely and effectively remove tough contaminants without damaging delicate surfaces. We used an eco friendly, citrus based tar and gunk remover from Eco Chem.

Scope of the Clean-Up:

Staircase: Removed tar buildup that had settled into the steps and surrounding surfaces.

Metal fence: Gently treated and cleaned tar streaks without scratching or harming the metal, white powder coated finish.

Concrete patio: Restored a stained, darkened patio back to its clean, natural tone removing spots of tar and construction debris.
