Newmarket Home Exterior Waterproofing Estimate - Window Well Water Intrusion Assessment
Today we visited a beautiful Newmarket home where the homeowner was experiencing water intrusion in their basement through the basement windows. After conducting a thorough inspection, we identified the root cause and provided a comprehensive solution estimate.
The Problem: Water Coming Through Basement Windows
The homeowner contacted us because they noticed water entering their basement specifically around the basement windows during heavy rainfall and spring snowmelt. This is a common issue in Newmarket homes, especially older properties where window well drainage systems can fail over time.
During our free inspection, we discovered:
- Failed window well drainage - The existing drainage system was no longer effectively directing water away from the windows
- Blocked weeping tile - The foundation's weeping tile system appeared to be compromised, preventing proper water evacuation
- Multiple affected windows - All four basement windows were experiencing varying degrees of water intrusion
- Foundation wall exposure - Areas around the windows showed signs of moisture damage and potential foundation issues
Our Professional Assessment
After completing our comprehensive evaluation, we identified that this was not a simple drainage fix but required a systematic approach to address the underlying waterproofing failures.
The affected area spanned both the side and back walls of the house, covering all four basement windows. The scope of work would involve approximately 35 linear feet of excavation to a depth of 8 feet to properly access and repair all affected areas.
Recommended Solution: Complete Exterior Waterproofing
Our recommendation included a comprehensive exterior waterproofing approach:
1. Professional Excavation
- Excavate 35 linear feet along side and back walls
- Dig to 8-foot depth to access foundation footing level
- Careful excavation to protect existing landscaping where possible
- Proper soil disposal and site preparation
2. Foundation Wall Waterproofing
- Clean and prepare foundation walls
- Apply premium waterproof membrane system
- Install protection board to prevent membrane damage
- Ensure complete coverage from footing to grade level
3. Window Well Drainage Installation
- Install new window well drainage systems for all four windows
- Proper gravel bedding and drainage pipes
- Connect to new weeping tile system
- Install window well covers where appropriate
4. Weeping Tile System
- Install new weeping tile along excavated sections
- Camera scope existing weeping tile to assess condition
- Provide detailed report on overall system status
- Recommend additional measures if existing system is compromised
5. Sump Pump System (If Required)
If our scoping reveals that the existing weeping tile system throughout the house is not functioning properly, we would recommend installing a sump pump system to ensure water from the newly waterproofed area is properly diverted away from the foundation.
