The Challenge: Moisture & Structural Risks in a Historic Home

Charles’ historic home in Markham, VA, had been in his family for generations. As a historically significant property, maintaining its original charm while protecting it from water damage was essential. However, moisture intrusion, poor drainage, and deteriorating stone window wells weakened the home’s foundation.
Worried about ongoing damage, Charles knew that DIY exterior foundation waterproofing wouldn’t provide the long-term protection his home needed. Instead, he contacted the LUX team for expert waterproofing outside foundation walls to safeguard his home while preserving its historic integrity.
After a comprehensive inspection, Russ, one of our foundation specialists, identified the following key problems:
✅ Aging Foundation Without Waterproofing – The home lacked waterproofing of foundation exterior, allowing moisture infiltration, increasing the risk of mold, and weakening structural components.
✅ Deteriorating Stone Window Wells – Two existing stone window wells showed deterioration, requiring careful parging and waterproofing.
✅ Need for Additional Window Wells – The home required two additional stone window wells to enhance ventilation drainage and prevent basement moisture issues.
✅ Poor Drainage System – The existing exterior drainage was ineffective, allowing water to pool around the foundation. increasing the risk of erosion, basement leaks, and long-term foundation damage.
✅ Short Downspout Extensions – The existing downspouts were too short, allowing roof runoff to collect dangerously close to the foundation.
The Risks of Ignoring These Issues
❌ Continued water infiltration, leading to mold and mildew growth
❌ Weakening of the foundation and stonework due to moisture exposure
❌ Potential collapse or failure of the existing window wells
❌ Increased basement humidity and energy inefficiency
Left unaddressed, these issues could compromise the stability and livability of the historic home. LUX developed a customized exterior waterproofing plan to prevent costly repairs to protect the foundation and the home’s historic charm.
