SHOW NOTES: Environmentally-Friendly Concrete: A new carbon-eating concrete will make truly green buildings possible. We’ll discuss this new commercial construction material. Space Heaters: Would you like to warm up a chilly area of your home? We’ve got recommendations for a great space heater. Stink Bugs: It’s stink bug season, when these creepy pests try to head indoors. We’ll share tips on how to keep stink bugs from invading your home.  Plus, answers to your home improvement questions. Hard Water: What is the best system to use if you’ve got hard water in your home? We’ll tell Brian why a traditional salt-based water conditioner is better than a salt-free type to treat his whole house. Cement Stains: The uncovered portion of Linda’s cement porch is peeling and looks terrible. We suggest a product she can use that’s quick, easy, durable, and much more attractive than repainting the cement surface. Roofing: Randy wants to know if his metal roof is ventilated well enough after the contractor removed some vents. We reassure him that it should be fine with the proper insulation and venting already in place. Countertops: Is it possible to smooth down the surface of a countertop with a leathered texture? Ann finds out that a granite countertop would be easier to replace, but she may be able to refinish a laminate surface. Home Improvement ROI: Tom wants to know how to calculate the return on investment of home improvements. We discuss the cost vs. value analysis to determine ROI. Water Heaters: Is a tankless water heater a good option? Pete finds out that tankless water heaters are dependable, affordable, and offer high energy efficiency. Windows: Should you try to repair old double-pane windows that won’t open or close properly anymore? Donna would be better off replacing her 20-year-old windows instead of trying costly or ineffective repairs. Heating: Bob is trying to decide between natural gas heat or oil heat. With oil prices rising, natural gas heat is a good option that’s more efficient and more affordable, with rebates and free utility installation often available. Pocket Doors: The sliding pocket doors in James’ bathroom are starting to wear out. We’ll share tips on how to lubricate the rollers or remove the doors to replace the mechanisms. Concrete Stains: Trees are dropping acorns that are staining the concrete driveway. Gail will need a bleach solution and a scrub brush to stay ahead of the dark stains.   Do you have a home improvement or decor question? Call the show 24/7 at 888-MONEY-PIT (888-666-3974) or post your question here.
