When to hire a pro
- If a tool binds, overheats, or you are unsure of safe technique, stop and reassess or hire help rather than force the cut.
- If you cannot fully stop the water, or water is near electrical outlets/panels, stop DIY and call a plumber.
- High-impact DIY mistake — Over-Tightening the Slip Nut: Tighten the slip nut just until it's snug, then check for leaks and tighten further if necessary.
- When hiring a professional, describe the issue with your sink strainer basket and provide the location of the sink. Ask if they have experience with similar repairs and if they have the necessary tools and materials.
- Ask for a detailed quote that includes the cost of the new strainer basket, labor, and any additional repairs. Be wary of low-ball estimates that may not include all the necessary work.
- Check if the professional has the necessary licenses and insurance to work in your state. Also, ask about their warranty and guarantee policies.
