"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

Yes, if you’re replacing a door slab, it must be the exact size of your existing door. If your new door is too small, you’ll need to purchase a new door to fit or hire a handyperson to make your frame smaller. Or if it's too big, you’ll need to return it or shave it down to fit.

Yes, barn doors can be too heavy, although the limitation is usually imposed by the mounting hardware you buy and not your home’s framing, unless you’re building an unusually wide door. To keep the weight down, you can opt for 1-by material rather than 2-by material, and choose a softwood like pine rather than a hardwood like maple or oak. Check the weight limits on your mounting hardware, and always attach your door track to studs rather than to drywall anchors.

Most of the time, a squeaky door is the result of dry hinges, where metal parts rub together without enough lubrication. Dirt, dust, or rust can also build up inside the hinge and add to the friction. Loose screws or slight misalignment can shift things just enough to create that irritating squeaking noise. Worn-out hinges or swelling wood from humidity changes can also be part of the problem on older doors. A good cleaning and proper lubrication usually take care of it, but if the squeak sticks around, it’s worth checking for bigger issues with the hinges or alignment. 

The best place to install a dog door is on an exterior door that leads to a fenced-in area of your rear yard. This position will let your dog go in and out as they need and still keep them safe in your yard when they’re outside. You should plan on installing the bottom of the doggie door a minimum of 3 inches above the bottom of your exterior door to maintain the structural integrity of the door, and never cut out a hole within 3 inches of exterior door glass.

Fire doors are more expensive than your run-of-the-mill residential composite door because of additional materials and expanding sealants that help the door slow down or even prevent the spread of temperatures over 1,000 degrees. If you have homeowners insurance, talk to your company and see if installing fire doors can lower your premiums, especially if you can install steel doors.
