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...

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.

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.


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.
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.
Determine needs vs wants: There is always a difference between what you WANT in your garage, and what you NEED. While you may want a high end entertainment complex, do you need it? Before you begin your project sit down and make a list of needs, and wants. By creating a prioritized list you keep yourself from overspending. Once you have your needs addressed, throw in a few wants.
If you have an existing garage in place, but no walls, floor, ceiling or finishes in place, the cost to finish your garage will be much less expensive than $10,000. Oftentimes, finished a garage entails adding a few beams or drywall. Contractors can install wooden or steal beams for a few thousand dollars. In addition, according to our drywall installation cost guide, you can purchase drywall for at little as $0.30/sf. If you hire a general contractor to install the drywall, expect to pay another $1,000. Overall, the cost to finish a garage should not exceed $5,000.

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.
Homeowners who are used to house paints should have no trouble applying either and cleaning up afterward. First, apply some H&C cleaner degreaser, a mixture of heavy-duty detergent and phosphoric acid. You simply sprinkle it on the garage floor with a watering can, work it in with a broom and let it foam the floor clean. Then, rinse the floor and let it dry. The stain is applied with a roller. It's ready for foot traffic in one hour and car traffic in 72 to 96 hours depending on temperature and humidity.
On the exterior we remove the siding on the front of the garage and installed new hardboard siding that matched the original on the building. Electrically we removed and relocated existing lights and added a ceiling fan as well as recessed lighting. Some additional outlets and network wiring was installed then connected to the home and panel box. The interior was insulated in areas such as the ceiling, stairwell and miscellaneous sections of the walls. We laminated (overlay) the existing sheetrock with 3/8″ wallboard on the sidewalls and stairwell and 1/2″ for the ceiling.

A 'Ready to Sell' garage remodel will give you the best ROI possible without the need for a permit. It may include finishing interior texture (already sheetrocked), painting, and changing a few light fixtures. This level is perfect for those who are preparing their home for sale and tends to be cosmetic in nature in order to present the home well to potential buyers.


Paint manufacturers have recognized these problems and have come to the rescue with new solutions. But a word of advice: If your garage floor sees heavy water leakage, if it's badly cracked or if it's damp and slimy all summer, don't apply any coating. In those cases, you're better off simply keeping it as clean as you can and then calling it quits.
