When it comes to garage insulation, homeowners have two options. Foil insulation (pictured above), tends to look like foil, but the inside is usually laced with heavy-duty polyethylene. The polyethylene is usually used in rigid sheets that are placed inside the cavities of your garage door. Once placed onto the garage, the polyethylene expands to fit into place.
Did you now that the garage is one of the biggest uninsulated areas of the home? Improperly insulated garage doors can vastly increase your heating and electric bills. Even worse, they can cause moisture damage once it rains or an uncomfortable setting every time you enter. Therefore, garage insulation tends to creep up with all garage remodeling projects, especially those concerning a finished garage.
Update Fixtures: If you have either old, or the most basic fixtures spend a little money and upgrade them. Utility lighting doesn’t have to be bare bulbs with an economy base. Use fixtures that fit into your garage design. Sometimes it has exterior lights, or interior lighting fixtures that just look completely out of place. Make sure you change out these fixtures to ones that fit the area.
Heating & AC ($1000-$5000): Adding central heat and air into your garage can either be simple or difficult. If you have a robust heating and air conditioning system in place it is as simple as expanding your existing ducting. If the additional square footage is more than your system can handle you will need to add in a new unit. Luckily, a small garage usually is able to be fit into your existing system.
If you're planning to maximize the space, add useful features, and otherwise make changes that are likely to appeal to a majority of homeowners, your renovation may end up being a worthwhile investment in your home's resale value. However, the quality of the work matters, especially if you're planning a major change such as converting the garage into a bedroom. Trading your garage space for a poorly insulated "bedroom" with no windows and the garage door intact won't do much to boost resale value.
For a garage-to-utility-room conversion, budget at least $6,000 for appliances, a utility sink, and space for sorting, folding and hanging laundry. A new utility room in place of an old garage brings convenience into your life, especially if you've spent years dragging loads of laundry up and down the stairs. This conversion will cost a bit more due to the addition of plumbing, but it'll be worth it.
