Went perfectly. I used Sean at my other home. His work there was so much better than others I tried. So, at my new home I made sure to look him up again. He didn't disappoint. He showed up when he said and came in under budget. I will hire again in fall and every time I need landscaping.

FAQs for french drain service projects in Knoxville, TN

Landscapers typically charge $25 to $50 per person per hour, which equals around $50 to $100 per hour for a two-person crew. These rates can vary depending on your location, the size of staff needed for the job, and overall job type. For example, a larger crew will be needed for structural additions and hardscaping versus planting flowers.

Landscaping architects are required to be licensed in all 50 states, whereas traditional landscaping contractors are not typically required to hold a certification. You’ll likely be working with a landscaping contractor for most residential projects. If you are redesigning your whole yard or adding in hardscape features, you will work with a landscaping architect at some point during the project. Be sure to check our state licensing tool to review the local landscaper guidelines.

We highly recommend leaving the work of replacing drain pipes to a professional plumber. Drain pipes are a key part of your plumbing system, and making mistakes during the installation or even using the wrong size pipes for your specific fixture can lead to an elevated risk of leaks and clogs. Additionally, drain pipes prevent harmful sewer gas from entering your home, so hiring a professional plumber is essential to keeping the risk of leaks and clogs low and avoid reducing your indoor air quality.
