Don’t Be Roped In by Amateurs
Hire an inspector that is certified, thorough, and knows what he’s doing.
Private well systems require specialized testing to determine lab-tested water quality and reliable flow for your household. Green Door Home Inspections provides comprehensive well and water inspections throughout Castle Rock, Douglas County, Denver, Aurora, and the Front Range, delivering same-day flow findings and lab-tested water quality results through state-certified Colorado laboratories.
A professional water well inspection evaluates your well system’s mechanical performance, flow capacity, and water safety. Whether you’re purchasing a home with a private well, maintaining your current property, or preparing to sell, a residential well inspection provides documented evidence of your system’s condition and helps you avoid costly surprises after closing.
A professional well system inspection goes beyond a simple pressure check. It includes trained evaluation of mechanical components, flow testing using the InterNACHI method, and laboratory analysis of water samples by a state-certified lab. Every Green Door well inspection is performed by an inspector who has completed InterNACHI’s 48-hour private wells course.
The Colorado Department of Public Health and Environment recommends testing private wells annually for bacteria and nitrates. Additional testing is necessary before closing on a home purchase, after any repairs or changes to the system, or when you notice changes in the water’s taste, odor, color, or pressure.
Our comprehensive inspection approach covers every critical component of your well system, from surface conditions to water safety.
We examine the wellhead for proper sealing, secure cap installation, and intact casing. Site grading around the well is checked to ensure that water drains away from the well, reducing the risk of contamination from surface runoff. Common concerns include cracked casings from soil movement, missing sanitary seals, and slopes that direct snowmelt toward the well.
The well pump flow test follows the InterNACHI method and runs for approximately one hour through an exterior spigot, with water directed safely away from the foundation. We monitor flow rate (measured in gallons per minute), pressure tank cycling, and pump behavior to identify issues such as inadequate production for your household size, short-cycling that damages pumps, or pressure inconsistencies that affect daily water use throughout your home.
Water samples are collected using sterile technique and sent to a state-certified laboratory in Colorado for analysis of total coliform bacteria, E. coli, nitrate, nitrite, and lead. The lead sample is a first-draw sample collected under EPA protocol, which requires that water sit unused in the plumbing for at least 6 hours beforehand. These contaminants pose serious health risks, and proper sampling procedures provide accurate results you can trust.
Flow-test and visual findings are delivered the same day. Laboratory results typically arrive within five to seven business days from the certified lab and are added directly to your report. When applicable, we reference Colorado Division of Water Resources permit records so you can verify well permit information for your property.
The well inspection costs $598 when bundled with a home inspection or as a standalone service. This package includes the complete flow evaluation, visual assessment, laboratory water-quality testing through a state-certified Colorado lab, and detailed reporting of all findings.
Bundling your well inspection with home, radon, or sewer inspections reduces travel fees and simplifies scheduling during your closing timeline. Combined services are completed in a single visit whenever possible, saving you time and coordination effort throughout Castle Rock, Parker, and the surrounding areas.
On-site testing takes two to three hours. Flow and visual findings are delivered the same day, with lab results following in 5 to 7 business days. Well inspections are scheduled on weekdays so water samples reach the certified lab the same day they are collected. We work with tight real-estate deadlines throughout the Front Range, so book early to secure a time that fits your closing timeline.
Mechanical failures include pump malfunctions, pressure tank issues, and electrical problems. Inadequate flow or pressure often signals a declining aquifer, an undersized pump for household demand, or clogged screens. Water-quality problems range from bacterial contamination to elevated nitrate levels from surrounding land use to lead from older plumbing components.
Typical repairs include pump replacement, pressure tank upgrades, whole-house filtration systems, or UV disinfection for bacterial issues. We document findings clearly so you can work with qualified local contractors to address issues. Our reports specify the type and severity of problems, helping contractors provide accurate estimates. Keep all repair documentation for future transactions and warranty purposes.
Test water annually, monitor pressure gauge readings for sudden changes, listen for unusual pump cycling, and maintain proper site drainage around the wellhead. Early detection of changes in taste, odor, or flow helps you address small issues before they become system failures requiring thousands in repairs.
Our team is led by a United States Marine Corps veteran. Every well inspection is performed by an inspector who has completed InterNACHI’s 48-hour private wells course. This commitment to standards and accountability provides consistent, thorough inspections you can depend on for critical real estate decisions.
We deliver same-day flow findings with photo documentation and prioritized recommendations. Visual evidence and clear explanations help you understand system performance and support informed negotiations or maintenance planning. Our reports explain findings in plain language, not just technical jargon.
Questions don’t end when the report arrives. We provide unlimited follow-up support to buyers and real estate agents throughout the closing process, reducing confusion and helping you move forward with confidence. We’re available by phone or email to explain findings or discuss repair options.
Private wells are regulated by the Colorado Division of Water Resources for water rights and well construction permits, and by local health departments for water quality and sanitary standards.
Well permits are issued by the Colorado Division of Water Resources (DWR), and permit records can be searched through DWR’s online database. For Douglas County properties, see our Douglas County well permit guide.
You can remain on the property, but avoid using water during the one-hour flow test to provide an accurate measurement of system capacity and pump performance.
State-certified Colorado laboratories typically return water-quality results within five to seven business days after sample submission.
The six-hour period is required for the lead sample. EPA first-draw protocol calls for water to sit unused in the plumbing for at least six hours so the sample reflects what you would actually drink after water has been standing in your pipes. Learn more about what’s included in a home inspection.
We provide laboratory test results for specific contaminants tested. Safe drinking water determinations should be made in consultation with health professionals based on complete testing and your household’s specific needs. See details about your inspection process and timeline.
