"Avi was a pleasure to deal with. I had a unique request: build a box to carry my French Bulldog on my cargo bike. Avi took my design and executed it to perfection, even matching the bike's paint. I was quite pleased with the result, and so was my dog!"

"We have hired Cesar and his team for several jobs now, and wouldn't consider anyone else. From first contact to the completed project, we were impressed. After having some bad experiences with contractors it was such a relief to find a team of professionals. Not only do they complete the project, but they went above and beyond. For instance, while shoring up our main staircase, Cesar fixed a door that never closed right, now almost a year later it still closes! The projects we hired him for were to replace loose tiles in our tub/shower and fix the faucets as well. Just yesterday they finished removing tile and carpet from our kitchen, hallway and bathroom. They also installed a combination of vinyl plank flooring, tile and a bathroom vanity. The job took only 2 days. Overall Cesar and his team worked quickly and efficiently, in a timely manner and they cleaned up afterward. I highly recommend this operation."

"I had a few things that I wanted done it all started with one bedroom window, five new window shutters and a front door shutter. The house being 41 years old needed a face lift. I also had them repair the front doorstep / sill. Family company that has a great crew and was able to complete everything in one day, I couldn't have been happier with the results and my wife is very happy to have all these repairs done. I highly recommend them and will use them in the future for other repairs"

"Don arrived on time for the appointment and started work quickly.  Our priority task was the installation of a number of light fixtures, which he was able to complete efficiently with time to spare for a few extra handyman tasks not on our initial list.  We also are preparing for a door replacement project, and Don was able to give an assessment of the required effort and a few flexible options for engaging his services on the project.  Overall a very professional and experienced handyman, and we expect to work with him again in the future.

Doors FAQs, answered by experts

Most modern, standard doors are 1 ⅜-inches thick, so you should aim for this thickness unless you're building a door to replace an antique door or fit into a non-standard wall opening. Thickness varies when installing a pocket door or sliding barn door, so a good rule of thumb is to measure your existing door, if possible. For standard doors, you can also measure from the inside of the door to the door stop to gauge the proper thickness.

High-tech solutions and strategic placement can help ensure the safety of your pet door. Pet doors can pose security risks, as well as the risk of stray or wild animals entering your home, but modern pet doors offer options like collar-based sensors to ensure doors will only open for your pet, and installing a pet door in an out-of-sight location or in a wall rather than a door can help to avoid intruders using the door to gain access to your home.

You can open up more space between the door and the floor by sanding the bottom of the door, but it will take longer compared to using a hand planer. However, you could use a belt sander, which some believe is even better than a hand planer for planing a door. Also, it could leave a smoother finish on the bottom of the door.

Steel doors last the longest, sometimes upwards of 100 years. Fiberglass comes in second, with a lifespan of 70 years. Wood doors have the lowest lifespan, with some wood types only last 20 to 40 years.

Using force to open a door is not recommended, as this could cause serious injury or permanent damage to your door and surrounding door frame. If it’s a front door that you’ve lost the keys for, it’s better to call a locksmith. If it’s an interior door without any lock that you plan on keeping, a handyman can help. Finally, if it’s an old door that you plan to replace anyway, a professional door installer can remove the stuck door and source a replacement.
