Door Installation in Hazelwood, MO | 10+ Years Experience
Interior and exterior door installation with proper jamb fit, shimming, hinge and latch alignment, and finished casing for Hazelwood properties.
Hazelwood Carpenters installs doors where proper jamb fit, plumb and level alignment, shimming, hinge placement, latch alignment, and finished casing determine whether the opening works correctly. Interior and exterior doors are handled within carpentry scope, fitting the door slab or prehung unit to the actual rough opening and jamb condition. With 10+ years of hands-on experience and insured workmanship, we handle the fitting and finishing that keeps a door operating cleanly rather than rubbing, sagging, or failing to latch.
Door installation is not a simple slab swap. The rough opening, head jamb, side jambs, threshold, hinge mortises, strike plate, and casing all have to land plumb, level, and square so the reveals stay even and the latch engages. Exterior doors add threshold, weatherstripping, sealant, and weather-exposure considerations, and when adjacent exterior work like siding, masonry, electrical, or security-system work is involved, that may require another qualified trade. Every opening is measured to the actual condition so the door fits the space as built.

Our Specialized Door Installation Services
Each service below covers a specific type of door installation, with real components and methods named for each.
Interior Door Installation
Interior door installation fits bedroom, office, closet, and other interior openings in Hazelwood homes where a new slab or prehung unit must operate cleanly within the existing opening.
Work covers jamb fit, shims to establish plumb and level, hinge mortises, latch and strike plate alignment, consistent reveals, and casing transitions that tie the opening into the adjoining trim.
The outcome is an interior door that opens, closes, and latches correctly with even reveals and a finished casing transition rather than a unit that rubs or gaps.
Exterior Door Installation
Exterior door installation handles openings exposed to weather in Hazelwood properties, where the threshold, weatherstripping, sealant, and surrounding trim all affect performance and durability.
Work covers opening condition, threshold fit, weatherstripping, sealant at weather interfaces, jamb and hinge alignment, and casing; when adjacent exterior work like siding, masonry, electrical, or security-system work is required, another qualified trade may be needed.
The outcome is an exterior door that fits the opening securely, seals against weather appropriately, and operates correctly with finished trim inside and out.
Replacement Door Installation in Existing Openings
Replacement door installation fits a new door into an existing Hazelwood opening where the rough opening and jamb condition must be measured before the replacement assembly is fitted.
Work covers measuring the existing rough opening and jamb, correcting minor carpentry irregularities, shimming for plumb and level, fitting hinges and hardware, and aligning the latch and strike to the existing condition.
The outcome is a replacement door that fits the actual opening rather than a nominal size, with corrected alignment and finished casing that integrates with the room.
Common Reasons Hazelwood Properties Need New Doors
Existing Door Is Damaged or Worn Out
Split slabs, worn hardware, dented panels, and deteriorated jambs reach a point where replacement is more practical than repeated repair. A new door fitted to the opening restores clean operation and appearance.
Door No Longer Fits the Opening Correctly
Homes that have settled or shifted often leave doors that rub, sag, or fail to latch. When the opening has moved enough, a new door fitted to the current condition resolves the operation where adjustment cannot.
Remodeling or Room Changes Require a New Door Assembly
Room conversions, flooring changes, and layout updates often call for a new door, swing, or style. A door installed to the remodeled opening keeps the finished room consistent and functional.
Signs Door Installation Needs More Than a Simple Slab Swap
Jamb Is Out of Plumb or Damaged
A jamb that is out of plumb, split, or deteriorated cannot support a clean installation. The jamb condition is evaluated and corrected or replaced so the new door lands plumb and level.
Opening Has Uneven or Inconsistent Reveals
When the gap between the door and jamb changes around the opening, the door reads as crooked and may rub. Shimming to a consistent reveal corrects the fit rather than forcing the door closed.
Threshold, Trim, or Surrounding Wood Is Deteriorated
Deteriorated thresholds, trim, or surrounding wood at exterior openings indicate moisture involvement. The damaged carpentry material is addressed as part of the installation scope rather than covered over.

Hazelwood Carpenters works with 10+ years of hands-on carpentry experience across finish work, cabinets, repairs, and decks. That experience shows up in jamb fitting, alignment, and trim integration.
Insured for Carpentry Work
Hazelwood Carpenters is insured. Insurance is one of the standing trust factors shown across the site and matters when a contractor is installing doors at your property.
Plumb, Level, and Square Fitting
A door only operates cleanly when the jamb is plumb, level, and square. We shim, align, and fit to the actual opening condition so the reveals stay even and the latch engages consistently.
Hinge, Latch, and Strike Alignment
Hinge mortises, strike plate position, and latch engagement are the details behind a door that works. We fit hardware to the actual jamb and slab rather than assuming a unit will land correctly.
Transparent Scope and Pricing Basis
Slab versus prehung, jamb condition, casing, hardware, and opening modifications are the real price drivers. Scope and useful planning ranges are shared before work begins.

Our Door Installation Process
Measure the Opening and Existing Conditions
We measure the rough opening, jamb condition, plumb and level, threshold, and adjoining trim so the door and any jamb work are scoped to the actual opening rather than a nominal size.
Confirm Door Type, Swing, Hardware, and Trim Scope
Slab versus prehung, swing direction, hinge and latch hardware, threshold, weatherstripping, and casing scope are confirmed so the installation matches the intended function and finish.
Fit, Shim, Fasten, and Align the Door/Jamb
The jamb is shimmed to plumb and level, fastened into framing, hinges are fitted, and the door is aligned so reveals are consistent and the latch engages the strike cleanly.
Install Hardware, Casing, and Finish Details
Hardware is installed and adjusted, casing is fit and fastened, weather sealing is completed where applicable, and a final operation check confirms the door opens, closes, and latches correctly.

Frequently Asked Questions About Door Installation
How much does door installation cost in Hazelwood?
Door installation in Hazelwood typically runs roughly $300 to $800+ per opening for interior doors and $600 to $1,500+ per opening for exterior doors, while installations requiring substantial opening carpentry are project-specific. Slab versus prehung, jamb condition, casing, hardware, threshold, and weather sealing are the main price drivers.
What is the difference between a slab door and a prehung door?
A slab door is the door panel alone, fitted into an existing jamb with hinges mortised and hardware installed on site, while a prehung door comes already hinged in its own jamb and is set into the rough opening as a unit. Prehung units simplify jamb fit but require the rough opening to be correct; slabs depend on the existing jamb condition.
Can a new door be installed in an existing jamb?
Yes, a slab door can be installed in an existing jamb when the jamb is plumb, level, and in good condition. The existing jamb is measured, hinge mortises are cut to match, and the slab is fit so the reveals stay even and the latch engages the existing strike.
Can you replace damaged door casing during installation?
Yes, damaged casing can be replaced as part of a door installation. Old casing is removed carefully to preserve adjacent wall finishes, and new casing is fit with consistent reveals and clean corners so the opening reads as finished.
Do exterior doors require more preparation than interior doors?
Yes, exterior doors require more preparation because the threshold, weatherstripping, sealant, and weather exposure all affect performance. The opening condition, weather sealing, and surrounding trim are addressed so the door seals and drains appropriately, and adjacent exterior trade work is handled by the appropriate trade when required.
Can a door opening be corrected if it is out of square?
Yes, a door opening that is out of square can often be corrected through jamb shimming, minor carpentry adjustments, and fitting the door to the actual condition. When the framing itself has moved significantly, the rough opening may need carpentry correction before a clean installation is possible.
