"We recently had a fantastic experience with Jim / OHI. They built us a beautiful new deck and installed a patio door, and the workmanship was excellent from start to finish. When we ran into unexpected building and zoning issues with the town, they were incredibly flexible and worked with us to adjust the project. Instead of the larger deck we originally planned, they created a stunning patio in that space, which turned out even better than we imagined. The crew was professional, reliable, and detail-oriented, and the results have transformed our backyard. We couldn’t be happier and highly recommend OHI to anyone considering a deck or patio project."

"I gave this man $3000 which was 33% of the job upfront. Was supposed to give him 33% at the halfway part And 34% upon completion. But when I went to my bathroom and realized you left drugs in my bathroom and I have small children. Not like that 3000 black and small cleaners caught easy and heâ s lucky he hasnâ t been charged with nothing. Only reason that happened is because I wouldnâ t pursue charges. He obviously is a drug addict and has a problem so maybe he should get help Possibly isnâ t the option maybe rehab is. If you paid for supplies, you got ripped off wait 10 years and it will all fall apart charges for certain stuff but buys different stuff so he can use the extra money to pick himself up drugs without nobody noticing, I am so terribly in grief over this. $3000 he ran off with how is Matt doing in business and not in a jail cell"

Window Door Contractors questions, answered by experts

French doors that open to exterior spaces are often installed to swing inward, as this makes them more secure than outward-swinging doors, due to the interior hinges being inaccessible from the outside. For interior doors, it’s personal preference which direction to hang your doors, but it’s common to have them open into the larger of the two spaces they’re separating.

Residential exterior doors should swing inward. While this cuts into your living space and prevents you from putting furniture near the inside of your door, it also means that the hinges will only be accessible from the interior. Hinges that sit on the outside of your home leave your property far less secure, as someone looking to get in could simply unscrew them and remove your door. Additionally, inswing exterior doors will be operable even if you have snow or other obstructions outside.

Steel doors are among the most affordable options for your front door. Steel doors are worth the cost if you’re looking for a budget-friendly door that maximizes home security and energy efficiency. Plus, they can last up to 100 years, making them a high-quality and long-term investment.

A well-installed storm door in good shape can add value to your home. But if it looks shabby or is hanging off its hinges, it could have the opposite effect. In general, the mere existence of a storm door likely won’t fetch you much more on the sale price of your home, but it can improve your home’s curb appeal and help it catch the eye of more potential buyers.

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.
