"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."

"Everything turned out well. They were great and we had no problems. We won't be using them in the future because of the overpriced estimate they gave us on 3 doors we wanted installed, following the windows."

Doors FAQs, answered by experts

New door knobs likely won’t have much of an effect on property value, but they can improve your home’s curb appeal and interior decor, which might lead some buyers to offer more for your home. However, in terms of personal value, adding new door knobs can be a game changer. New door knobs not only function better than older ones in most cases, but they make your home secure, and there’s a lot to be said about the peace of mind a new exterior door knob can provide.

Many doorways feature two door jambs. These are installed on both sides of a doorway to prevent the door from swinging too far. Door jambs usually stop the door at 180 degrees when closed.  A doorway floor transition sits between the door jambs on the floor, helping to create a safer and more aesthetically pleasing transition from one flooring type to the next. 

If you don’t know which door sweep to buy, look into getting a strip or bristle sweep. They’re easy to find at the store, work well for most doors, and the simple installation is DIYable. Before buying one, measure your door width and make sure the one you want is long enough. Most door sweeps are 36 inches long, and you can cut them down to size with a hacksaw.

An interior French door should last you anywhere between 30 and 50 years, while an exterior French door unit will last around 15 to 30 years on average. Exactly how long your French doors last depends on the quality of the materials you choose, with vinyl doors lasting far less time than fiberglass, metal, and clad-wood doors. Upgrading to shatterproof glass can also improve the lifespan of exterior French doors.

Installing a dog door is generally a straightforward process that handy DIYers may feel comfortable attempting on their own. Because the process usually involves cutting a hole in your existing door or wall, some homeowners may prefer to hire a handyperson who has experience with this type of installation to ensure the job is done right.
