Exterior doors play an important role in your home’s appearance, security, weather protection, and everyday comfort. Over time, worn doors, damaged frames, deteriorated weatherstripping, and poor fit can lead to drafts, sticking, water intrusion, and difficulty opening or closing properly.
Home Pros STL LLC provides professional exterior door and storm door installation services for homeowners, landlords, property managers, and real estate investors throughout St. Louis, St. Charles County, Jefferson County, and surrounding Missouri communities.
Whether you are replacing an aging entry door, installing a new storm door, or correcting a poorly fitted exterior opening, our team can help evaluate the existing conditions and develop an appropriate installation scope.
Exterior Door Replacement
Home Pros STL LLC installs and replaces residential exterior doors in a variety of home styles and configurations.
Exterior door installation may include:
Removal of the existing door
Removal of the existing frame when required
Rough opening evaluation
Shimming and leveling
New prehung door installation
Hardware installation
Lockset installation
Weatherstripping
Exterior trim installation
Interior trim repairs
Caulking and sealing
Threshold adjustment
Final operational check
The exact installation method depends on the type of door, condition of the opening, existing framing, and surrounding finishes.
Entry Door Installation
A properly fitted entry door should open and close smoothly, latch correctly, and fit the opening without unnecessary gaps or binding.
Home Pros STL LLC can install customer-selected entry doors including:
Steel exterior doors
Fiberglass exterior doors
Wood exterior doors
Insulated entry doors
Single entry doors
Other compatible residential door systems
Door performance depends on both the quality of the product and the condition of the surrounding opening.
If the existing frame, sill, or rough opening is damaged, repairs may be required before the new door can be installed correctly.
Storm Door Installation
Storm doors can provide an additional exterior barrier while allowing ventilation and helping protect the primary entry door from direct weather exposure.
Storm door installation may include:
Measuring the existing opening
Preparing the mounting surface
Installing the storm door frame
Hanging and aligning the door
Installing the closer
Installing handles and latches
Adjusting sweep and seals
Final operation check
The existing exterior trim and mounting surface must be in suitable condition for the storm door system being installed.
Damaged or deteriorated trim may need to be repaired or replaced before installation.
Exterior Door Frame and Sill Repairs
Older or damaged exterior door openings sometimes require more than simply replacing the door slab or prehung unit.
Common conditions may include:
Rotted jambs
Deteriorated sill areas
Damaged subflooring
Loose framing
Out-of-square openings
Water damage
Failed caulking
Previous improper installation
Damaged exterior trim
Home Pros STL LLC can evaluate visible conditions and include appropriate repair work in the installation scope when necessary.
If concealed deterioration is discovered after the existing door or trim is removed, additional repairs may be required before installation can continue.
Door Weatherstripping and Sealing
Proper sealing around an exterior door can help reduce drafts and limit unwanted air and water movement around the opening.
Door installation may include:
New weatherstripping
Door sweeps
Threshold adjustments
Exterior-grade caulking
Approved perimeter sealing
Minor alignment corrections
Weatherstripping and caulking cannot correct significant structural movement, failed flashing, damaged framing, or other larger building-envelope problems.
If water intrusion is present, the source should be identified before permanent repairs are completed.
Hardware and Lock Installation
Exterior door installation may also include compatible hardware such as:
Door knobs
Lever handles
Deadbolts
Hinges
Strike plates
Door closers
Storm door handles
Other approved door hardware
Existing framing and jambs must provide suitable attachment for the selected hardware.
Electronic locks, specialty access systems, or unusual hardware may require additional installation requirements.
