As the days get longer and the last remnants of winter weather recede, the external facades of homes across the region begin to reveal the toll taken by the harsh winter elements. If you're the owner of a historic brick home in Washington, DC, a testament to our rich architectural heritage, you're likely contemplating the best way to clean your home's exterior without causing lasting damage. At first blush, power washing can appear to be a quick and efficient solution to blasting away winter's grime. Though power washing can offer immediate and satisfying results for specific types of homes, it's vital to understand why it's generally not a suitable cleaning method for old brick. Here’s why you should consider exploring safer alternatives that will protect the integrity of your historic brick home.
The Dangers of Pressure Washing Old Brick
Power washing, which can initially seem gratifying as it makes dirt and grime vanish in seconds, unfortunately poses significant risks to historic brick homes:
- High-Pressure Damage: Typical power washers can emit water at pressures ranging from 1,300 to 3,000+ PSI. This intense force can aggressively erode historic brick's soft, porous material and the delicate, lime-based mortar, stripping away character and compromising structural integrity.
- Mortar Erosion: Historic masonry often utilizes softer, lime-based mortar instead of modern, harder cement. The high pressure of water can easily wash this crucial binding material out from between the bricks, leading to gaps, structural weakness, and inevitable costly repairs in the future.
- Water Intrusion: Pressure washing forces water deep into the tiniest crevices of brick and mortar, potentially leading to internal moisture issues. This moisture can cause mold growth or freeze in colder temperatures, leading to frost damage that exacerbates the wear on your brick.
- Aesthetic Damage: Historic bricks' unique patina and texture are part of their charm and value. Power washing can strip away these features, leaving the bricks bare and often altering their historical appearance and value.
Safer Cleaning Alternatives for Your Historic Brick Home
Your historic home can be a gracefully aging beauty with a clean exterior that highlights its antique elegance. The key is to choose effective but gentle cleaning methods tailored to the unique needs of older brick:
- Soft Washing: Making use of lower water pressure and specialized cleaning solutions tailored for older masonry, soft washing cleans the brick without a destructive impact, preserving both the brick's integrity and its historical aesthetics.
- Chemical Cleaners: Specific formulations designed for historic masonry can gently dissolve dirt and grime without damaging the brickwork. To ensure they do not discolor or degrade the masonry, it's essential to test these products in an inconspicuous area first.
- Using soft-bristled brushes and a mild solution of water and detergent can be a highly effective and controlled method to clean delicate areas without the risks that are typically associated with high pressure.
