Whether you need foundation work, utility line installation, or site preparation for construction projects, ourprofessional excavation servicesprovide the precise digging and grading expertise required for successful project completion.

Our earthmoving capabilities include foundation excavation, utility trenching for water and sewer lines, and careful grading that ensures proper drainage around new construction.

Proper landscape grading prevents water from pooling around your home while creating attractive, functional outdoor spaces. We reshape terrain to direct water flow naturally away from structures.
Retention Systems: We design and install systems that capture and slowly release stormwater, reducing flooding and erosion while protecting local waterways.
Erosion Control: Our soil erosion control measures protect slopes, prevent sediment runoff, and maintain landscape integrity during construction and afterward.
Retaining Walls: When elevation changes are needed, we install retaining walls that provide both structural support and attractive landscape features.

All our work meets strict safety and regulatory standards:
OSHA Safety Standards: Our crews follow all occupational safety requirements for excavation work, including proper trench safety and equipment operation.
EPA Regulations: We comply with environmental regulations for stormwater management and groundwater protection.
Local Building Codes: All excavation and drainage work meets local code requirements and passes required inspections.
Municipal Permits: We handle all necessary permits and coordinate with utility companies to ensure safe, legal work.
Water in Basement: Recurring basement flooding indicates need for comprehensive drainage solutions and possibly excavation for exterior waterproofing.
Foundation Cracks: Water damage to foundations often requires excavation for proper repair and installation of drainage systems.
Soggy Yard Areas: Persistent wet spots in landscaping indicate need for grading corrections or subsurface drainage installation.
Erosion Problems: Soil washing away during storms requires both drainage improvements and earthwork to prevent future damage.
Construction Projects: Any building project requires proper site preparation, utility trenching, and grading work.
Site Assessment: We evaluate water flow patterns, soil conditions, and existing drainage to design effective solutions.
Engineering Consultation: Complex projects may require input from engineering consultants and soil testing labs to ensure optimal results.
Professional Installation: Using modern excavation equipment and proven techniques, we complete projects efficiently while minimizing property disruption.
Quality Assurance: All work is inspected and tested to ensure proper function and code compliance.
Chautauqua County receives over 60 inches of precipitation annually in some areas — and when that combines with Western New York’s clay-heavy soils, drainage problems are not just common, they’re expected. Clay soil holds water instead of draining it, turning yards into standing water zones and pushing moisture against foundations. Jamestown’s hilly terrain adds runoff to the equation. McCandless designs and installs drainage systems built specifically for these conditions, drawing on 50 years of working in Chautauqua County soil.
McCandless Plumbing & Excavation serves Jamestown and the surrounding Chautauqua County communities, including Dunkirk, Fredonia, Lakewood, Westfield, Mayville, Falconer, Bemus Point, and Findley Lake.

You need excavation for foundation work, utility installation, drainage system installation, site preparation for construction, basement waterproofing, and resolving severe water management problems that require earthwork solutions.
Effective drainage directs water away from foundations, prevents basement flooding, eliminates standing water that damages landscaping, reduces soil erosion, and protects structural integrity by managing groundwater and surface water flow.
Excavation typically requires building permits, utility location clearances, and sometimes environmental permits. We handle all permit applications and ensure compliance with local regulations and safety standards.
Simple drainage installations take 1-3 days, while major excavation projects may take 1-3 weeks depending on scope and weather conditions. We provide realistic timelines during project planning.
We minimize landscape disruption through careful planning and precise equipment operation. Some temporary impact is unavoidable, but we restore affected areas and can coordinate with landscaping professionals for full restoration.
We follow all OSHA safety standards, call utility location services before digging, use proper trench safety equipment, maintain safe distances from structures, and ensure all crew members are properly trained and equipped.
Some drainage solutions like surface grading require minimal digging, while others like French drains need trenching. We recommend the least invasive effective solution for your specific water management needs.
