The first step is often fixing a cracked floor or leveling it, and sometimes even staining it to make it look more attractive; the repairs cost $500-$12,500, and stains range from $2 to $10 per square foot. Drywall is typically put up, which costs from $1 to $2 per square foot. Adding boards for a storage space above the garage typically costs about $2 per square foot.
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.

The floors of your new space are a unique issue. Your garage is built with drainage in mind. Code requirements mandate that the concrete slab has a slope built into it to ensure water drains away from the home. The installation of the subfloor will correct the slope issue of your floor. Using a subfloor allows your new space to be converted back into a garage should the next home owner wish to do so.
As the wife and I gear up to make our way back to our hometown here in North Florida, we’re seriously considering building a new house on some acreage, since we can’t find anything that we really are looking to call our last home. Naturally, I’ve already been working on designing my stand-alone dream garage. I mean, as long as we’re building stuff… ?
Pick: Pick what your new room is going to focus on. Your small garage can either do one thing perfectly or a lot of things partially. Think of it like any small room in your home. Your small bedroom wouldn’t be able to be a bedroom, media room, work space, and storage area. Your small garage can’t do all of these things either. So pick one focus and ensure your plan addresses it. Some average room sizes to help you pick are:
I just finished "re-modeling" my garage...before I touched it it had just taped drywall and concrete block walls, unfinished cement floor, wires for the garage door openers hanging all over the place, holes in all the walls/ceiling. It was a typical, dirty, dark garage.I painted the concrete walls with Behr waterproof masonry paint and the rest of the walls and ceiling with the same color behr paint (twilight gray-to lighten it up).I did the floor with Behr 1 Part Epoxy, which, takes forever to prep for, but the result is worth it. You first need to sweep very good, then clean/de-grease and etch the concrete using a floor cleaner rented from HD...then let it dry. I let it dry for about 2 weeks. Once I was sure the concrete was dry, I applied 2 coats of concrete bonding primer. I let that dry for about 24 hours, and I was finally ready for the paint. The paint goes on easy, one coat was plenty. I sprinlled in some color flakes and let it dry 24hrs. I then began my first of three coates of low gloss sealer. The finished result was very pleasing...I then re-installed my Gladiator Garage Works 8 foot work bench, wall cabinet and tool chest as well as a second wall cabinet and large gearbox that I purchased for my new garage... I also built a wooden cabinet around the circuit breakers and painted it gray along with the framing for the garage doors, a beam in the middle and the door into the house. I finished with gray vinyl trim molding around the walls.I also mounted the bikes, a shop Vac and misc. brooms, saw horse, etc... on the wall(s). All of the wires from the garage door openers were hanging down and sloppy (prev. owner) so I disconected everything and ran it through PVC for a cleaner look. I then added a few finishing touches, Bud Light neon clock, pictures (NE Patriots Cheerleaders), and mounted my novelty license plate collection as well as a few other items...Moving all of my furniture/tools out of the garage was a big project in itself, and I lost my basement(i.e. Gym) for about a month and a half, but the end result is a very clean, organized garage that is "my" place...
Another problem is moisture vapor. Moisture vapor from the ground works from below to loosen the coating's bond with the concrete. In the case of alkyd paints (also called oil-based paints), the moisture will react with the alkaline materials in the concrete and form a soap. This process is called saponification. The soap loosens the paint's bond with the concrete. Never use alkyd or modified alkyd paints on concrete.
A garage remodel is usually much cheaper than a home renovation because the foundation, roof, and walls are already built. Many garages also have electrical and plumbing installed to some extent. The actual cost of a garage remodeling project, however, depends on what the renovated space will be used for. While a new home gym won't require much in the way of amenities, converting a garage to an office, apartment, or bedroom requires adding significantly more creature comforts.
