"Entire process exceeded my expectations from the initial contact I had with Alliance to the completion of the project. The proposal I received from Keith provided the level of detail I was looking for and he did a great job in going over the siding products Alliance offered to detailing all the necessary steps in the process. The installation process went very smoothly and was completed in a timely manner. The crew led by Serg were extremely professional, knowledgeable and focused. I could not be happier with the work they did and Serg kept me updated on how the project was progressing and was quick to reach out to me with any questions he had on the proposed installation approach. Therefore, I would recommend Alliance for any home improvement needs that you may need addressed. Lastly, I was so satisfied with the siding installation Alliance did I am now having them replace the two entry doors to my garage. Thank you again Sergiy, Keith, Serg and the rest of the installation crew. CFP Sr."

Door Repair FAQs, answered by experts

Misaligned doors, damaged frames, faulty closers, broken locks, and automatic door sensor failures often require repairs.

First, make sure you seal or finish your door after installation. There are many different sealants and wood finishes on the market designed to prevent moisture from infiltrating wood surfaces. Additionally, do your best to control humidity around your door using a dehumidifier. Any exterior wood doors should be protected by glass storm doors to reduce water exposure.

WD-40 can be used on squeaky door hinges, but it is generally considered a temporary, short-term solution rather than a long-term fix. While it can silence a squeak in a pinch by breaking down rust and grime, it is not a true lubricant, as it contains only a small amount of lubricating oil that evaporates quickly. Using WD-40 alone may lead to the squeak returning and can attract dirt and dust, potentially causing more wear on the hinge over time. For a more effective and lasting solution, it is recommended to first use WD-40 to clean the hinge, then wipe it clean. Afterward, apply a dedicated lubricant such as silicone spray, white lithium grease, a metal or plastic lubricant, or an oil-based product like petroleum jelly.

Most professionals charge between $100 and $300 to replace a door threshold. Interior door thresholds will typically sit toward the lower end of that range, while exterior door thresholds will usually be higher, as your pro will need to waterproof and weatherproof the new threshold. Replacing a marble threshold for a bathroom door is one of the most expensive threshold projects, as marble is far more expensive and more challenging to work with than wood.

First, it's possible that your door hinge pin was designed not to be removable for security purposes. If this is the case, the pin is either encased within the barrel or secured using rivets. If a pin is stuck even though it's intended to be removable, it may be weighed down by paint or rust. If dried paint is causing a pin to stick, use a knife to carefully cut through the layers of paint that are caked into the area between the plate and pin. If rust is the culprit, lubricate the area.
