  • Heating or cooling your garage should be done with a separate system from heating and cooling your house.
  • Air seal the garage from the house. Investigate the garage ceiling to ensure the joists are blocked off above all walls common to the house. If there is a door to the garage from the house, check the weather stripping and door sweep. Air seal around trim, electrical boxes or any other penetrations.
  • If there is a heated room above the garage, make sure there is insulation in the garage ceiling. Make sure the insulation in the garage ceiling is in full contact with the flooring above. Seal any electrical boxes in the garage ceiling.

  • Trees provide numerous important functions on your property, including shading to reduce the cooling needs of your home and storm water management through the interception of rain on leaves and branches. Be sure you or your contractor follow best practice guides for protecting all site trees during your project.
  • First costs often drive decisions for many products, but high maintenance and replacement costs can end up swallowing any savings from a lower first cost. Consider the warranty of your driveway material, the maintenance requirements before making your choice.
  • Pervious pavement requires engineering to ensure sufficient sub-surface materials are designed and installed properly to account for the structural loading and the water infiltration rates desired. Note that there are maintenance requirements (periodic vacuuming), but the benefits of improving storm water management are very compelling.
