Every project comes down to cost, so it only makes sense to start there. According to our garage remodeling cost estimator, the average garage remodel runs $8,582. Keep in mind, this takes the full garage into consideration. That includes the garage door, flooring, windows and plenty of other renovations. For those remodeling one aspect of their garage, of course, expect the final price to be much less. In fact, we have even seen garage remodels cost as low as $900.
If you decide to expand your garage to make more room for tools or storage, this is considered adding on to your home, and costs will typically go up. Home addition costs fall between $20,000 and $70,000 for most homeowners, depending on the size and type of space built. Your contractor will frame out new walls and expand the room's foundation. If you intend to keep the space the same only reorganizing it, you may have only the costs associated with purchasing and installing shelving and cabinetry.

The cost of installing five windows falls somewhere around $5,000, or about $1,000 per window. If your garage doesn't have any windows, plan to add at least one. This is especially important if you want to list it as a bedroom or rent it out. You'll need an egress window big enough for a person to escape through in case of a fire. Egress windows average about $3,500.
The home office will cost at least $5,000, making it one of the more affordable options when it comes to converting your garage into living space. Like a bedroom, a home office needs all the basic amenities, such as walls, floors, and a ceiling. It needs climate control and a window. This room may also require additional outlets that let you connect computers, printers and charging stations. You'll need internet access and a high-speed connection, as well as lots of storage and organization options.
Not every home owner has a few hundred thousand dollars to put towards renovations. Some of us need to save and therefore need to know how to remodel a garage on a budget. The need to make every dollar count means you need to make smart choices. Smart choices require having the best information. We’ve put together the best tips from across the internet for you.

But about those new formulations, one is Epoxy Shield garage floor paint. It's a waterborne coating consisting of epoxy and acrylic resins with color chips that you sprinkle over while the coating is wet. Its manufacturer says it’s specifically formulated to withstand hot-tire pickup, moisture vapor and attack by solvents and chemicals that drip from a car or come in on the car's tires. It comes as a kit that consists of a cleaner-degreaser, two paint components that you mix together and nonskid color chips. To apply, first clean and degrease the floor. Then mix the two-part coating together and roll it on. Finish up by broadcasting the nonskid chips onto the coating while it’s still wet. You should be able to walk on the surface in four hours and drive on it after seven days when it’s fully cured. The kit costs about $60.
If you are considering a new bedroom, take into account the number of bathrooms in the home. The usual ration is one bathroom to two bedrooms. This means if you have a three bedroom and two bath home, adding another bedroom is fine. If you have a two bedroom and one bath home, adding another bathroom means you really would need to add a bathroom as well.

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.
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. 
Garage floor coatings fail for a number of reasons. First, the floor is usually not clean enough to receive a coating. Years of grime have to be removed using solvents and proprietary cleaners. These are sold at paint stores, hardware stores, home centers and industrial supply houses. If the floor is really filthy, consider pressure washing. Rent a machine that produces at least 1,200 to 2,000 psi. Also, buy some grease-cutting detergent at the rental store. Along similar lines, you might consider a steam cleaner if a pressure washer is unavailable.
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).
One of the best ways to have a garage space that increases your home value is to make sure it is in good repair. When a potential buyer does their very first walk through your garage can help make or break the sale. If it hasn’t been touched in 20 years the time to spruce it up is before the first buyer comes to look. When thinking about a garage that is in good repair think about things such as;
Look for a contractor who specializes in garage remodels - or at least one who has experience remodeling garages. Ask to see pictures of previous jobs such as the before and after garage conversion picture shown here. A good contractor should be able to show you garage conversion designs and you can also get some inspiration from looking online at garage remodeling ideas. Remodeling a garage is different than remodeling other areas of the home, and it helps to have a contractor who understands that.

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.”
If you are considering a new bedroom, take into account the number of bathrooms in the home. The usual ration is one bathroom to two bedrooms. This means if you have a three bedroom and two bath home, adding another bedroom is fine. If you have a two bedroom and one bath home, adding another bathroom means you really would need to add a bathroom as well.
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.

Leaky doors and windows let in uncomfortable drafts and increase heating and cooling costs. Check your garage service door to be sure it has good weather stripping and a threshold that seals tightly to the bottom of the door. In most cases, if your service door is missing a threshold and weather stripping, it’s more efficient to replace the door with a new, weather-tight version. You can buy an inexpensive prehung metal exterior door at home centers and lumberyards.
