"Kassi scheduled our work very promptly and another staff member followed up on the details. Everything went smoothly on the day, and took less time than I expected. John was friendly and efficient -- taking care of business in short order. Replacing the light fixtures by our front door was a little tricky re: the cedar siding, but he effortlessly adapted the installation to the situation. Perfect! The old wooden post mailbox was rotted and barely standing...he took it all away, dug a deep new hole and installed the steel post, using quick setting concrete, and fitted the new mailbox. He even scalped some sod to leave on top... When John was finished, you would have thought the mailbox had always been there. I plan on calling on Mr. Handyman, and John, in the future."

"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!"

"Excellent from start to finish. Complete renovation of kitchen/dining room, removing a wall, new exterior doors and windows, siding, etc. Extremely happy with the craftmanship of the finished product, but also the communication and process along the way. Dave and Marvin don't rush around frantically to jump to the next project. They work calmly and methodically, taking the time to explain things, answer questions, and give recommendations along the way. Very responsive and kept us informed every step of the way. Everyone who visits is blown away with the transformation."

"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  is a  very personable, energetic handyman. My house is 60 years old and is gradually in need of some repairs. He replaced a doorknob, reseated a heavy door that had come off its hinges, repaired a broken chair, replaced a leaky washer in the kitchen tap, reseated an outdoor light knocked out by a storm which he will replace at a later date, and installed a new mailbox.
I would certainly recommend Don because I think he could repair anything.

"This was a small job, and Alex did it right. All I needed was my cellar door rehung, as it was uneven. It turned out to be a little more complicated than that, but Alex fixed it, and I am very pleased with how it no longer is uneven."

Doors FAQs, answered by experts

While both sides of a front door should get painted for aesthetic reasons, you don’t have to do each side at the same time. As a matter of fact, you’ll probably want a different paint type and color for the interior section of the door than the exterior side. Consider each side of the door your personal canvas and make the paint match any nearby decor. 

The most common size for an interior door is 80 inches tall and 28 to 32 inches wide. However, a standard interior door can measure anywhere from 24 to 36 inches wide, depending on its intended use and the available space. According to most building codes in the U.S., a door must be at least 80 inches tall and 24 inches wide.

If you’re installing a pocket door into an existing door opening, the new space will need to be twice the width of the existing door, plus an inch. You'll need to double that number if you’re adding dual pocket doors.

As long as you do it carefully, you can sand and restain hollow core doors. However, it’s risky because the veneers on hollow core doors are so thin that sanding and restaining might cause damage to the doors. If you do move forward with this project, sand the doors lightly with a medium-grit sandpaper.

The best direction for a gate to swing depends on its location and purpose, but swinging inward is the general rule. An inward swing is often considered safer, prevents the gate from opening into public spaces like a sidewalk, and may be required by local building codes.

There are exceptions and specific considerations. If your property is on a slope, an inward swing might not be possible. For a deck gate, it's safest to have it swing away from any steps. In a backyard, the direction can be a matter of preference, though an inward swing can be helpful when carrying heavy items like a wheelbarrow into a garden.

Regardless of direction, ensure the gate can open fully without hitting any objects or blocking spaces. While an inward swing is standard, a gate that can swing both in and out offers the most flexibility if your setup allows for it.
