"Stop your search now, you've found the contractor you should go with, you will not be disappointed! This is the second project I've had Ben and his team do at my house and they knocked it out of the park again. This time around they remodeled two bathrooms and put in a new hall closet. They were rock stars throughout the entire project. There wasn't a single time that any reasonable request I made was denied. This was a huge load off my shoulders when dealing with such permanent decisions that comes with bathroom remodels. They were very patient and understanding as I ran into several supply issues that were out of my control during the project as well. It's very obvious that he's had years of experience with construction. His attention to detail and his forethought allowed my wife and I to rest easy knowing that they would always be able to bring up potential issues as well as offer us solutions to issues that we were going to run into many steps down the line."

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction. Thank you again to the entire A1-Builder team!"

"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"Wonderful!   These guys are pros.   We had a tough job because we wanted the curbing to cut into some large and smaller boulders.   We also wanted colored concrete.  They did an excellent job!  I would recommend highly."

Garages FAQs, answered by experts

Garage door insulation can last anywhere from 20 to 100 years depending on the type of insulation. Cellulose has the shortest lifespan coming in at between 20 and 30 years, while spray foam, mineral wool, and fiberglass can last between 80 and 100 years with proper maintenance. 

Humidity plays a role in how long more susceptible insulation materials—like fiberglass—last. Once fiberglass batts reach the 15-year mark, you'll need to routinely inspect your insulation to ensure that it is in mint order.

Always lock the door that separates your garage and your home. However, garage doors are seldom entrance points for thieves. It takes quite a bit of work and noise to pry open a garage door, so thieves often opt for windows or unlocked doors. Unless they have access to the motor which controls the door, as long as it's functioning properly you shouldn't worry too much about it.

It is typically cheaper to build a garage than to buy a prefab one if you can provide most of the labor yourself. If you plan to hire a contractor for the entire build, a prefab garage or kit will likely be less expensive. However, even with a garage kit, you may still need to hire professionals to install the foundation, concrete floor, and handle electrical and plumbing work. If you are not an experienced builder, it can be a worthwhile investment to hire a local garage builder who can manage all aspects of the project, including coordinating other necessary professionals.

Indoor propane heaters are safe to use in a garage. You may be able to use an outdoor propane heater inside a garage in some instances, as long as the garage door remains open and there’s constant airflow to allow the carbon dioxide and carbon monoxide to escape. Other garage heaters include electric heaters and gas heaters.

Yes, you can pressure wash epoxy floors, but you must take precautions to avoid damaging the surface. While most epoxy floors can be cleaned with a mop, you might choose to pressure wash if the floor is stained, has ground-in dirt, or is covered with mold or mildew. To do so safely, first soak any stains or dirty areas with a gentle cleanser. Use a lower pressure setting with a gentle nozzle, such as a green, white, or black tip, or a 45-degree angled tip. Keep the spray nozzle at least 18 inches away from the floor to protect the surface. Using a surface cleaner attachment or a rotary scrubber can also help prevent overspray. Be cautious if using a power washer that heats the water, as the combination of heat and pressure may be too powerful and could damage the epoxy coating.
