"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"If I could give Hugo and his team 10 stars I would!! To say I am beyond impressed with their work is an understatement. From the first time we met Hugo for an estimate, we knew he was not only a professional but also a genuine person. A person you actually want working for you! Every step of the way Hugo communicated what they were doing, and always ensured we were happy with the progress. He was easy to communicate with, and we knew the work on our house was in the very best hands possible, at the most reasonable price as well! His team did impeccable work. Their workmanship is truly the highest quality. From the high hats installed, to the tile they put down, to the amazing paint job, and more we were truly impressed overall! Weâ re obsessed with how the work turned out, my husband and I keep saying we canâ t wait to have Hugo and his team come back and do more projects! Thank you so much to Hugo and his team for transforming my first floor into a beautiful living space!"

Window Door Contractors questions, answered by experts

While sometimes used interchangeably, a screen door differs from a storm door. Screen doors are composed only of the frame and screen, whereas a storm door has more components. A storm door comes with a glass panel that can be installed instead of a screen to keep the air inside the home. A storm door offers more protection , but costs more than a screen door, so weigh the pros and cons to determine the best option for your needs.

WD-40 will make you think that you’ve fixed your door’s squeakiness. Still, the product doesn’t contain enough lubrication to oil the hinge and keep it operating smoothly and effectively. In addition, WD-40 can attract dirt and dust to your hinges, causing more wear and tear and shortening their lifespans. Learn how to properly lubricate your door hinges so they last as long as possible.

The strike plate, hinges, and handle are the parts of a door most prone to damage. These parts see the most frequent use, causing them to wear and twear faster than other parts of a door. If you’re experiencing door issues, check these three parts first to see if they need repairing or replacing. 

A butterfly hinge—also known as a surface mount hinge or dovetail hinge—is exactly what it sounds like: a hinge that resembles a butterfly. This type of decorative hinge, which is mounted on the surface of a door or cabinet, consists of two panels. One panel is mounted on a stable surface like a door frame and the other is mounted on the surface you need to open. It hinges open and closed like the wings of a butterfly.

The typical time it takes to replace a patio door is between three and five hours. That time frame includes the removal of the old door and completing any necessary repairs before installing the door. However, the project could take up to a full day, depending on the door’s design and the surrounding wall structure.
