From sales to installation, the process was exceptionally smoothly and everything happened as was originally scheduled and promised. Communication was excellent, advice from the estimator was spot-on, the quality of the doors even better than what we expected and the installation was EXPERT. The doors look fabulous, work perfectly, and the installer did a much better job than what we could have done ourselves. We are so glad that we decided to outsource this service and we highly recommend this company.

"Excellent service having my garage ceiling drywalled. They arrived when they said they were going to and were super about cleaning up after the job. Every step was thoroughly explained, including why they chose the materials they did. They had 2 other businesses come in to handle a couple of things. They explained why they did that and still came in under the estimated cost for the job. I am very pleased and will definitely not hesitate to hire them in the future."

Doors FAQs, answered by experts

A prehung door is a door that comes ready to install, already mounted in its frame with hinges and stop molding included. Because everything is factory-aligned, installation is quicker, more precise, and convenient, as you don't need to drill or align the hinges yourself. This makes it a smart option if your current frame is damaged, uneven, or if you're working on a new build. Installation involves fitting the entire unit into the rough opening, shimming and leveling it, and then securing it. If you are replacing an existing prehung door, the process is even simpler, often just requiring you to swap the old unit for the new one and secure it with a few screws. Prehung doors typically cost only slightly more (around $20) than a door slab alone, making them an efficient choice.

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.

You can often fit a new door slab into an old frame as long as the frame’s in decent shape. The frame needs to be solid, square, and free of warping or rot. The new door has to match the old one in width, height, and thickness, and the hinge and knob placements need to line up or be adjusted carefully. However, if your frame is damaged, swapping just the door won’t cut it. In that case, replacing the entire unit would be the best move for a smooth, secure installation.

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.

Steel doors have a few primary disadvantages. They’re hard to customize since they can’t be cut to fit an opening; they’re cumbersome and thus difficult to install on your own; and they don’t have the same aesthetic appeal as wood doors. Finally, while they’re highly durable and secure, they are susceptible to dents, scratches, and rusting.
