Start by insulating the walls. Buy unfaced R-13 batts for 2×4 walls and unfaced R-19 batts for 2×6 walls. Match the width of the batt (15-1/4 in. or 23-1/4 in.) to the stud space. Cut batts carefully for a tight fit. Next, staple 4-mil poly to the walls and ceiling. Embed the poly sheeting in caulk around the perimeter of each piece to create an airtight seal. Seal the seams between sheets and seal the poly to electrical boxes with caulk or special sheathing tape (it’s typically red and looks like packing tape).
While some homeowners fully transform their garages, others simply want to install a new garage door. Luckily, replacing a garage door is a rather simple project, for a trained professional. The reason we say trained professional is due to the garage door spring. These springs are wound up very tight and one small mistake can turn into a serious injury. Therefore, play it safe and contact a garage pro whenever you’re installing or replacing your garage door. 
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.
Hiring a remodeling expert really is necessary. A professional will ensure that all building permits and inspections are up to date. They can also redo your garage space to make it more appealing -- both visually and functionally. Garages are an important consideration for homebuyers when deciding whether to buy a property. Displaying a professional finish can go a long way in helping you get the best price possible for your home.
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 don’t want to spend $10,000 on a garage remodel, you could partially finish your garage. You can frame a concrete garage the same way you you’d finish a basement. Wooden crossbeams are secured to the floor, and the remainder of the framing is built up from there. Walls of either paneling or sheetrock can then be fastened, making your garage look and feel like another room of the house. Sheetrock is very often used for garage ceilings, allowing you to choose a paint color, and the same can be said for the walls. This is a job any general contractor can accomplish for a few thousand dollars. You could use metal studs, as opposed to wood, when framing to cut down material costs significantly.
Besides a brand new room, there are plenty of other benefits that come with remodeling garages. First and foremost, if you simply update your garage with new flooring, windows, insulation or garage organizers, you instantly increase the value of your home. While you may not see a 100% return on investment the day you sale, you will surely get more than you would have before the garage renovation.
Wall Units: If you have a big enough garage, wall units for storage can make your garage a great selling point. This can be a project you do yourself for a few hundred dollars. If you are not a do-it-yourself sort of person look for options that don’t have the look of interior cabinetry. Select cabinets that look like they belong there.  The cost for garage cabinets ranges from a few hundred to a few thousand dollars.
Most unfinished garages have the bare minimum of outlets and lights, so you’ll want to add a few. And in some cases, you’ll have to reroute wiring that’s attached to the face of studs or the underside of ceiling framing. We had to reroute phone wires, door opener control wires and plastic-sheathed cable in our garage. Remove surface-mounted wiring and move it into the stud space, or reroute it over the top of the ceiling joists or trusses.
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.

The overhead garage door can be a big source of drafts and heat loss. Recently installed doors usually include a weather-stripped stop around the perimeter. But older doors may be lacking a weather strip. Luckily, it’s an easy fix. Garage door weather stripping is available at home centers and hardware stores, and installation is straightforward. If your overhead door is uninsulated, search online for “garage door insulating kits.”

I stink at drawing. So pencil and paper isn’t an option for me when working to design my perfect garage (which I’ll unveil at some point in the future). Instead, I’ve been using SketchUp Make —a free 3D modeling software program, once owned by Google, that’s been around for almost 20 years now. And while CAD-style programs can be quite intimidating, SketchUp is super-easy to use and has a huge active community made up of all kinds of people—from architects and interior designers to woodworkers and other creators.
Is your garage currently only being used for storing things? Well, if it is, maybe you should consider putting it to better use. This article will explore the many possibilities a garage could give you, how to remodel it, and how to make sure you don’t break the bank doing it. We’ve divided it into different sections, each can be accessed through the links below, or you can simply scroll in order to read it in its entirety.
So if you are in need of a garage but don’t have a lot of money then consider this option. It could still be used as a great protector of your vehicles and other items. And would certainly make a great workspace as well. The only thing I wouldn’t be certain about would be the storage of personal items. But that could be worked around if this project could be done on a budget that works for you.
As you plan, the following tips can be indispensable. Don’t start without giving this list a look. Our list can save money, time, and money, and hassle. Go over these tips and apply all the ones you can to your own project. Remember that this is a starting point and that you should try to use these to help your own brainstorming for more ideas specific to your own situation.
Like wood stains, masonry stains are less viscous than paints. They soak into the masonry and don't form a film the way paint does. Unlike film-forming coatings, stains won't make your garage floor feel like the deck of an aircraft carrier. Because of this, stains are somewhat more forgiving and easier to apply and reapply as they wear off and become dirty. One of the oldest (perhaps the oldest) masonry stains available is H&C, now owned by Sherwin-Williams and sold at local paint stores. This venerable brand has been used in the Southern U.S. for many years. It's available in a wide range of colors and it can be tinted to any color you prefer. It's available in two formulations: a solvent-base (that is unavailable in California) and a waterborne acrylic available nationwide. The solvent-based formulation is the tougher one, so if you have both available, choose the stronger route unless you're very sensitive to solvent fumes.
When considering a small garage remodel, you can pay as little as $2,500 to as much as $30,000.  On average, the cost will be around $11,000, if you consider the national average. These costs are not set in stone, though. Your choices on materials will largely determine the overall cost. Your budget will take less of a hit on a smaller garage, which is another bonus, and there are many ways to save. A breakdown of the costs follows.
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.
