Exterior doors are one of the most functionally critical components of a home’s envelope. They are also one of the most neglected. A door that looks intact can be failing as a thermal barrier, a security barrier, or both — and most homeowners don’t realize it until the problem is advanced enough to cause visible damage or a meaningful spike in utility costs.
In Chicago, the conditions that accelerate door failure are present every year without exception. Freeze-thaw cycles warp frames and compromise seals. Sustained below-zero temperatures expose every gap in a door unit’s weatherstripping and threshold. Summer humidity swells wood components that winter cold then contracts. Over time, that cycle degrades even well-installed doors — and it destroys poorly installed ones quickly.
We are a local door supplier and installer with over 20 years of experience serving Chicago and the surrounding suburbs. We supply and install entry doors, exterior doors, front door replacements, and energy-efficient door units for residential properties throughout the Chicagoland area. Every product we supply carries a lifetime warranty.
This page covers each service in detail. Identify what your home needs, then request a free estimate. We will assess your existing doors on-site and provide a clear, specific recommendation.
Entry Door Installation in Chicago
Entry door installation is the foundation of this category — and the service with the broadest application across Chicago’s residential market. Whether you are replacing a full unit in an existing opening, installing a door in a remodeled space, or adding an entry point as part of an addition or conversion, the installation quality determines how the door performs for the next two to three decades.
We install entry doors throughout Chicago and the northwest suburbs. Every installation begins with a proper assessment of the rough opening — framing condition, existing moisture barrier, sill condition — before any product is ordered or delivered. A new door installed into a compromised opening performs like the door it replaced. We do not skip that step.
Chicago’s residential stock is diverse. Dense urban two-flats on the Northwest Side have different framing conventions than mid-century ranches in Des Plaines or newer two-stories in Glenview. Our crew has worked across all of it. We measure to the specific conditions of each opening and install accordingly — not to a generalized standard that ignores what’s actually there.
Door style, material, and hardware selections are made in consultation with the homeowner before anything is ordered. We work with established manufacturers and carry options across steel, fiberglass, and wood-look finishes in a range of architectural styles.
What you can expect:
Rough opening assessed and prepared before new door unit is installed
Entry door and frame installed plumb, level, and fully sealed against Chicago weather conditions
Proper flashing, weatherstripping, and threshold installed as integrated components of the unit
Wide selection of styles, materials, and hardware from established manufacturers
Front Door Replacement in Chicago
The front door is the most visible component of any home’s exterior. It is also, in many Chicago-area homes, one of the oldest — original units from the 1960s and 70s that have been patched, rehung, and weatherstripped repeatedly without addressing the underlying frame degradation that makes those patches necessary in the first place.
A front door that sticks seasonally, gaps at the top or sides, or requires force to latch is not a door problem in isolation. It is almost always a frame problem. The door slab may be structurally sound, but a frame that has been through 50 freeze-thaw cycles no longer sits square, no longer holds weatherstripping correctly, and no longer provides the tight perimeter seal that keeps conditioned air inside and Chicago weather outside.
We replace front doors as full units — door and frame together — throughout Chicago and the northwest suburbs. Replacing the slab alone into a compromised frame produces a temporarily improved door that will revert to its previous performance within one to two seasons. Full unit replacement solves the problem at its source.
This is a common project in established neighborhoods across Lincoln Square, Andersonville, and the near northwest suburbs, where homes have genuine architectural character worth preserving — and where a correctly specified front door replacement enhances that character rather than working against it.
What you can expect:
Full front door unit replaced — door slab and frame together, not slab alone
Old unit removed cleanly without damage to surrounding siding, trim, or interior finish
New door hung level with smooth, consistent operation and a tight perimeter seal
Available in traditional, craftsman, modern, and custom configurations to match the home’s architecture
Entry Door Replacement in Chicago
Entry door replacement driven by security and performance concerns follows a different evaluation process than front door replacement driven by aesthetics. The homeowner’s primary questions are functional: Is this door holding a seal? Is this frame providing adequate resistance? Is this unit performing as a thermal barrier or simply as a physical barrier with significant gaps?
In Chicago’s older residential neighborhoods — Portage Park, Jefferson Park, and across the northwest suburbs — a substantial number of homes are carrying entry door units that fail on all three measures. Hollow-core slabs in frames that have been through five decades of freeze-thaw stress. Weatherstripping that has been replaced multiple times but can no longer compensate for a frame that no longer sits square. Thresholds that have been shimmed and adjusted until adjustment is no longer possible.
At that point, repair is not a viable long-term answer. Full unit replacement — door, frame, weatherstripping, and threshold as an integrated assembly — is the correct solution. We carry out entry door replacements throughout Chicago and the northwest suburbs with that standard as the baseline.
Every replacement begins with an inspection of the existing opening. If the rough framing behind the door frame has been compromised by moisture infiltration — a common finding in homes where a failing door has been in place for years — that damage is addressed before the new unit goes in. Installing a new door over damaged framing transfers the problem forward rather than resolving it.
What you can expect:
Existing door unit removed, rough opening inspected before new unit is installed
Any framing or moisture barrier damage identified and addressed prior to installation
Full replacement unit installed — door, frame, weatherstripping, and threshold as an integrated assembly
Measurable improvement in air infiltration, thermal performance, and security after installation
Energy-Efficient Exterior Door Installation in Chicago
An exterior door’s thermal performance is determined by three components working together: the door panel itself, the perimeter seal between the door and the frame, and the threshold seal at the bottom. A failure in any one of those three points produces measurable heat loss. A failure in all three — which is the condition of many aging door units across Chicago’s housing stock — produces a thermal liability that costs money every month from November through March.
Energy-efficient exterior door installation addresses all three points in a single unit. Insulated foam-core door panels replace hollow or minimally insulated slabs. Compression or magnetic weatherstripping replaces worn pile or foam tape seals. Insulated adjustable thresholds replace worn or fixed thresholds that no longer contact the door bottom consistently.
The combined effect is a door that performs as a genuine thermal barrier — not simply a physical one. Homes across Chicago’s Northwest Side and the northwest suburbs where older door units remain in place consistently report noticeable reductions in drafts and improved room temperature stability near entry points after installation of a properly specified energy-efficient unit.
Summer performance is an equally valid consideration in Chicago’s climate. An insulated door unit that retains conditioned air during July and August reduces cooling load just as it reduces heating load in January. The investment applies across the full year, not only during the heating season.
What you can expect:
Insulated foam-core door panel with high thermal resistance rating installed
Compression or magnetic perimeter weatherstripping providing consistent seal across all four edges
Insulated adjustable threshold eliminating air infiltration at the door bottom
Performance benefit across both heating and cooling seasons in Chicago’s climate
Exterior Door Installation in Chicago
Secondary exterior doors — side entries, back doors, garage entries, basement walkouts — receive a fraction of the attention that front doors do, despite taking comparable or greater weather stress. North- and west-facing back and side entries on Chicago-area homes are directly exposed to prevailing winter winds. A poorly sealed back door can produce air infiltration equivalent to or exceeding that of a failed window unit.
We install and replace exterior doors in any opening around the home throughout Chicago and the northwest suburbs. Secondary entries in older Niles, Morton Grove, and Des Plaines homes are among the most commonly neglected door units in the residential market — original installations that have been in place since the home was built, never replaced, and now well past the point where repair is cost-effective.
Installation procedure for secondary exterior doors follows the same standard as primary entry door work. Opening assessed. Framing condition checked. Moisture barrier inspected and repaired where necessary. New door unit installed plumb, level, flashed, and sealed. The fact that a door faces the back of the house rather than the street does not change what correct installation requires.
Door specifications are matched to the home’s existing exterior finish and cladding. We work with vinyl, fiber cement, brick, and wood exteriors without requiring modifications to surrounding materials during installation.
What you can expect:
Any exterior opening handled — side entry, back door, garage entry, or basement walkout
Opening assessed and prepared to the same standard as primary entry door installations
Door matched to existing exterior finish and cladding — no modifications to surrounding materials
Properly flashed, weatherstripped, and sealed against wind-driven rain and sustained cold
Frequently Asked Questions
What is the difference between a door supplier and a door installer? A supplier provides the product. An installer puts it in. We do both under one contract. You are not coordinating between a supplier who sells you a door and a separate installer who may not be familiar with the product. We supply and install, which means accountability for the complete result.
Should I replace just the door slab or the full unit? It depends on the condition of the existing frame. If the frame is structurally sound, square, and holding its seal, a slab replacement can be appropriate. If the frame is warped, out of square, or no longer holding weatherstripping correctly — which is the case with most frames over 20 to 25 years old in Chicago’s climate — full unit replacement is the correct long-term answer. We will assess the frame when we come out and give you a direct recommendation.
How long does exterior door installation take? Most single-door installations are completed in two to four hours. If framing repairs are required, additional time is needed. We will give you a realistic timeline before work begins.
What door materials do you carry? We work with steel, fiberglass, and wood-look composite doors depending on the application, performance requirements, and homeowner preference. Each material has distinct advantages — we will walk you through the options during the estimate.
Do you install doors in winter? Yes. We work year-round throughout Chicago. Cold weather installation requires specific sequencing to minimize heat loss during the work period. We manage that process as a standard part of winter installations.
What is a thermally broken door frame? A thermally broken frame incorporates a low-conductivity barrier that separates the interior and exterior sections of the frame material — preventing cold from conducting directly through the frame into the home. It is the door frame equivalent of a thermally broken window frame, and it matters in Chicago’s climate for the same reasons.
Do your products come with a warranty? Yes. Every product we supply and install carries a lifetime warranty on materials.
What areas do you serve? We serve Chicago and the broader Chicagoland area — including Des Plaines, Park Ridge, Morton Grove, Niles, Glenview, Winnetka, Naperville, Evanston, Hoffman Estates, and surrounding communities.
