Answers: What are the best tool and material recommendations for common carpentry problems like nailers, impact wrenches, trim, and sagging floors?

• Cordless nailers
• Cordless impact wrenches
• Screws versus nails
• PVC trim
• Sagging kitchen floor support
• Crown molding installation and touch-up

What it concludes

• Start with an 18-gauge brad nailer as a beginner for carpentry projects.
• A 1/2-inch cordless impact wrench is a worthwhile investment for DIYers handling structural screws and car tires.
• For trim work and finish carpentry, nails are preferred over screws because they are easier to shoot and do not require pre-drilling.
• PVC trim board is rot-resistant, pet-resistant, and holds paint well, making it a good choice despite its higher cost.
• Support columns and joice reinforcement are necessary to fix sagging kitchen floors built over a basement concrete slab.
• Cedar is a preferred evergreen tree and material for rot resistance and exterior woodwork in New England.
