"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 is a thorough professional - he arrived at the agreed upon time, reviewed the work, offered several suggestions, setup time expectations, set about his work, and finished up without much intervention.
When he started his work, he setup drop-cloths and also cleaned  up before he left.

For installing the bi-fold doors, he rightly suggested opening up the packaging and measuring them for the door frame. The clearance in the door frame was a bit tight and he informed me upfront that would lead the doors to not close fully. I appreciated this honesty.

Overall I am very happy with Don's work and would strongly recommend him."

Doors FAQs, answered by experts

No, cellar doors are not all the same size, although they are standardized. Typical sizes are 4 feet or 6 feet wide. Keep in mind that if your cellar bulkhead is very old, it’s probably not standardized. Instances like that are when steel foundation plates can come in handy to ensure your new doors will fit.

To choose the best door, start by pinpointing its most important job in your home, then choose the material and style based on that function. Simply put, there’s a world of difference between what an interior bedroom door and driveway-facing entryway door do for your home. Thinking about your door's purpose first, then its look and style, will help you make the right choice and stay on budget.

Kick plates are usually installed on the “push” side of a door, but there are plenty of reasons to install them on both sides. Interior kick plates can offer protection from pet scratches, doors being kicked closed, and even kids’ toys during enthusiastic play sessions. Consider what kind of use and abuse your door gets to determine which side or sides to install a kick plate on.

You can attach the hinges to either the door or the frame first, depending on your preference. The order will not affect how the door hangs or the ease of installation. However, we recommend starting with the top hinge over the bottom one for stability, as it’s much easier to support the door from below while you install the top hinge. It will also be easier to pull the door outward from the hinges as it hangs from the top than it would be to push the door toward the hinges, as there’s less clearance on the lock side.

The lifespan of your door depends on the door type, its wear and tear, and the weather conditions in your area. For instance, front doors last between 20 and 60 years, depending on the material. Garage doors, on the other hand, last between 15 and 30 years. Interior doors don’t get hit with the elements and can last between 20 and 50 years, if not more.
