"We hired Ben and his team to do a full remodel of a 1940 bungalow in Burbank. Immediately upon meeting Ben I knew I wanted to work with him - he clearly has the intelligence, experience, and taste I was looking for, with excellent problem-solving and communication skills. Surprises arise during construction, but Ben was always direct and communicative. When a problem arose, he explained the situation, offered multiple solutions and the costs/tradeoffs of each, and we agreed together on the best course of action. The craftsmanship is wonderful, and even after the house was finished, he remained available for questions. Our house isn't a multimillion dollar compound, but Ben and his team treated it like one within our budget. Our remodel had a lot of ups and downs, but through it all he was a great guy and I'm happy to call him a friend even years after the work is done. Highly recommend!"

"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!"

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

Garages FAQs, answered by experts

No, there should not be a gap between your garage door and the floor. Gaps can make your garage less energy efficient, leading to higher energy bills. They also create an entry point for pests like rodents and insects, as well as rain and melted snow, which can lead to foundation damage or mold issues.

If you have a gap under your garage door, potential causes include an uneven garage floor or worn-out weather stripping. To fix it, you can try several solutions:

  • Replace the weather stripping: The seal at the bottom of the door may need to be replaced.

  • Adjust the garage door: You may be able to adjust the closing position on your garage door opener to eliminate the gap.

  • Inspect the floor: If the concrete floor has shifted or is uneven, it may need to be repaired to create a level surface.

If these solutions do not resolve the issue, it is best to call a garage door repair specialist to inspect the door and floor.

If you have a garage heater that is 1,500 watts or more, it will need its own breaker. As a good rule of thumb, no appliance should exceed 1,500 watts per outlet for best outcomes. Consult a local garage heating service to determine the power needs for your outdoor or indoor space.

On average, a garage door can last between 15 and 30 years. However, this lifespan is influenced by several factors, including the quality and material of the door, local climate conditions, and how frequently it is used and maintained.

Key factors affecting longevity include:

  • Material: Wooden doors can last 20 to 30 years or more, while steel doors typically last 15 to 20 years. More robust options, like triple-layer steel, can last 25 to 30 years with proper care. The number of layers in a door also contributes to its durability, with each additional layer potentially adding five years to its life.

  • Maintenance: Regular inspections, cleaning, and immediate repairs can significantly extend the life of your garage door.

  • Usage and Climate: Doors in harsh climates or those used very frequently may wear out faster.

  • Components: Individual parts have different lifespans. For example, automatic openers may fail sooner than the door itself without regular maintenance, and garage door springs typically need replacement every 7 to 12 years.

While the door panels are designed to last as long as the door, they should be replaced sooner if they become visibly damaged, impact the door's smooth operation, or create a security risk.

If you also have a standard door leading to your garage, install a robust deadbolt lock and reinforce the frame with security plates. Then, secure any windows with shatterproof glass or film to deter break-ins. Consider a smart garage door opener for your car entrance, enabling remote monitoring and control through your smartphone. Motion-activated lighting around the garage to deter intruders is a great way to amplify these security efforts. Lastly, educate your family on security practices, such as keeping the garage entrances closed and locked.

The decision on whether a garage or an extra room adds more value depends on several factors, including local market demand, location, and buyer preferences. Generally, added living space is more desirable to most buyers, and the utility of the new space determines its return on investment (ROI). Converting a garage into a livable area like a home office, guest room, or entertainment space can add significant value. An additional bedroom, especially one with a bathroom, will likely add the most value. However, adding a garage may be more valuable in areas with limited parking or harsh climates.
