St. Louis Door Replacement

Make Your Home Look Great & Stay Comfortable!

A front door is so much more than just an entryway to your home—it’s a sign of security and comfort all in one. For visitors, it’s a welcoming invitation to your home, while for intruders it is an imposing barrier to keep them out. Doors are also a huge part of your home’s energy efficiency and even your overall comfort, offering a distinct barrier that keeps conditioned air inside and the elements out.

If you are looking to upgrade your home’s appearance and improve your home comfort, a new door will do just that while also boosting your home’s security. Our comfort consultants are ready to make the process seamless and stress-free by offering experienced guidance and premium products from some of the industry’s most recognized names.

Door Installation

Who you trust to install doors in your home is just as important of a decision as the brand of doors you choose. No matter how great the equipment, doors installed incorrectly can present issues in your home. Poorly sealed doors allow for air leaks, and poorly secured doors can impact your family’s security. Our experts understand the importance of a careful, precise door installation, with the goal of maximizing energy efficiency and improving the beauty and quality of your entire home.

Frequently Asked Questions

What doors do you service?

We service all entryway doors for your home, including both front doors, back doors, side entryway doors, and more. We also offer services for patio doors, including sliding glass doors. We offer everything from standard-sized doors to custom doors of varying dimensions, materials, and designs.

What is a standard door size?

“Standard” is somewhat of a subjective term when it comes to doors. The most common door size is 80 inches tall and 36 inches wide, but doors can often vary based on needs and requirements. Exterior doors are typically thicker for added security and protection, but will typically run roughly the same size. Of course, double doors, French doors, and sliding doors may have different dimensions depending on the size of the opening.

How do you measure a door’s size?

Measuring a door is pretty straightforward. Simply measure the width and the height of the space inside the door frame (do not include any of the frame itself). Also measure the thickness of your door for the full dimensions. Generally, you will want to replace your door with a door of the same thickness, but this can sometimes be changed should you desire it.
