How much does it cost to install a whole house water filtration system?
Most whole-house water filtration installations with Gold Star cost $2,000–$5,500+. Exact pricing depends on your home's plumbing, water test results, and system type (carbon, sediment, or added RO at sinks). We start with a free consultation, then confirm a flat, upfront price after an on-site assessment. We serve Nassau County, including Garden City and Hicksville. Ongoing filter replacement and maintenance are available, and 24/7 emergency support is offered for failures. <br/>
