Why Replacement Doors Are a Worthy Investment

Curb Appeal – Personal Style

Instantly change the look of your home without a major remodel. It can be as simple as changing the door style from traditional to contemporary, widening the entry way, or adding sidelights to allow more light in your entryway.

Increased Security

Newer patio and entry doors have multiple points of locking for additional security and peace of mind. Steel and fiberglass doors are an extra layer of protection because they are difficult to kick in and they are more tamper-proof. If security is a serious concern, you may want to replace all exterior doors that may be a prime target for criminals.

Advanced Comfort

Older wood doors and their framing wear out over the decades. If you feel a draft around any of your entry or patio doors, you are feeling outside air coming in, which means your conditioned/heated air is escaping. This problem can be easily corrected with a new door and framing.

Increased Efficiency

An improperly installed door or an energy-inefficient model does more harm than good. If you have noticed a draft or irregular/frequent air conditioning activations, it may be time to consider installing a new door.

Glass or “patio” doors, especially sliding doors, lose much more heat than other types of doors because glass, while visually appealing, is a poor insulator. Most modern glass doors with metal frames have a thermal break, which is a plastic insulator between the inner and outer parts of the frame. Models with several layers of glass, low-emissivity coatings, and low-conductivity gasses between the glass panes are usually a sound investment. We are happy to help you find and install the perfect doors to maximize beauty while minimizing air leakage.

Another reason to replace an old door and frame: mold and water damage. An older, ill-fitting door could allow mold to grow due to damp weather or water damage from rain. Installing a new door and frame ensures your comfort and health safety.


Be prepared for lifestyle changes as you and your family grow. You may need a wider door for baby strollers now, but if this is your “forever home” you may need to accommodate walkers or wheelchairs. Installing entry doors that provide easy access is a lifestyle improvement. Older homeowners may want to consider these changes: switching to a wider door with a zero-clearance threshold; a lever-style door handle that can be opened with an elbow; or trading out steps for ramps.
