We’ve been working in Allentown long enough to know that no two garage doors here are the same. The city splits into two distinct worlds: the dense row-home neighborhoods of the urban core with their narrow alley garages, and the sprawling suburban-style homes on the west side built decades later with completely different garage configurations. Jason Reed, our owner and lead technician, has spent 11 years navigating both — from the tight alleys off Hamilton Street to the two-car attached garages near Cedar Crest Boulevard. That local knowledge means we show up with the right hardware the first time, not a truck full of standard parts that don’t fit your opening.

In Allentown specifically, we’ve built our reputation on solving problems that franchise crews walk away from — custom-sized doors for 6’6″ alley openings, low-headroom track systems in garages built before overhead doors existed, and concrete repairs that have to happen before a new seal will work.

Our Garage Door Installation Services in Allentown
New Door Installation
A new door installation in Allentown starts with understanding what you’re working with. In the 18104 west-side neighborhoods near Cedar Crest College, we’re often replacing original 1980s and 1990s doors that have finally reached end-of-life — springs, cables, and openers failing simultaneously. In the central ZIPs, we’re frequently starting from scratch in alley garages that have never had a proper modern door. Our new door installations include removal and disposal of the old door, precise opening measurements, and hardware selected for your specific headroom and clearance. A typical new door installation in Allentown runs $700–$2,200.
Single Car Door
Single-car doors dominate Allentown’s older housing stock, but “standard” doesn’t apply here. The 8-foot-wide single door common in postwar suburbs is often too wide for central Allentown’s narrow alley garages, where 7-foot or even 6’6″ openings are common. We fabricate custom panels and modify headers when needed. Single-car steel doors in Allentown start around $700 for basic models and run toward $1,400 for insulated versions with hardware that fits your specific opening.
Double Car Door
Double-car doors are standard in Allentown’s 1970s–1990s subdivisions, particularly in 18104 and the outer ZIPs. These 16-foot openings demand precise spring balancing and robust track hardware — especially important given the Lehigh Valley’s freeze-thaw cycles that stress components year after year. When we install a double door on a west-side home, we’re also evaluating whether the existing torsion spring system can handle the new door’s weight, or whether a full spring replacement should happen now to avoid a second service call in six months.
Custom Garage Door
Custom garage door work is where Allentown’s unique housing stock really shows. The 1910s–1940s row-home garages in the 18101–18103 ZIPs frequently need custom-sized panels, low-headroom or high-lift track systems, and specialized bottom seal configurations to handle heaved concrete thresholds. We’ve sourced 6’8″ custom steel doors with modified stile patterns, fabricated wood-composite panels to match historic trim, and designed seal systems for openings where the floor isn’t level enough for standard weatherstripping. Custom garage door installations in Allentown range $700–$2,200 depending on fabrication complexity and hardware requirements.
Steel Doors
Steel doors are our most common installation in Allentown for good reason. They withstand the road salt corrosion that destroys hardware on alley-facing garages, offer insulation options for the Lehigh Valley’s cold winters, and can be fabricated in custom sizes without the maintenance demands of real wood. We install Clopay and Amarr steel doors with gauge ratings and insulation values selected for your garage’s exposure — critical for detached alley garages that have no buffer from wind and temperature swings. Steel door installations in Allentown typically fall in the $700–$2,200 range.

Trusted Brands We Service in Allentown
We work on what you have — and we install what will last. Our training covers Chamberlain, Genie, Clopay, and Amarr systems, and we stock parts and hardware for these brands to keep turnaround times short for Allentown customers. When we recommend a Clopay steel door for a salt-exposed alley garage, or a Chamberlain opener with battery backup for a home near the frequent power fluctuations of Allentown’s older grid, it’s based on field experience with how these products perform in Lehigh Valley conditions. We don’t push brands we don’t know, and we don’t install equipment we can’t service.
Common Garage Door Installation Problems We See in Allentown Homes
- Freeze-thaw heaving defeats standard seals. The Lehigh Valley’s repeated winter freeze-thaw cycles — temperatures crossing 32°F multiple times each season — heave concrete aprons in older alley garages. We frequently grind thresholds flat or install specialized seal systems before a new door can achieve a weathertight close. This is nearly unheard-of in newer 18104 subdivisions with properly poured slabs.
- Narrow openings demand custom fabrication. Single-car garage openings under 8 feet wide in the 18101–18103 ZIPs require custom panel widths or header modifications. Standard 9×7 or 8×7 doors won’t fit, and inexperienced installers often discover this mid-job. We measure twice and fabricate once.
- Road salt accelerates hardware corrosion. Allentown’s heavy municipal salting splashes directly onto alley-facing detached garages with no driveway buffer. Tracks, bottom brackets, and hardware corrode faster than in suburban settings. We specify galvanized or stainless hardware for these installations, not standard-grade components that will seize in three years.
- Legacy one-piece doors create structural challenges. Many 1940s–1960s Allentown garages still have original one-piece swing-up doors with obsolete hardware and no modern weatherseal. Retrofitting these openings for sectional doors often requires jamb reinforcement, header modifications, and sometimes structural assessment — work that goes far beyond a simple door swap.

FAQs — Garage Door Installation in Allentown
No, a standard 7-foot-high door won’t fit in a 6’8″ opening without structural modification. We fabricate custom-height panels — typically 6’6″ or 6’8″ — and pair them with low-headroom track systems designed for tight clearances. This is common in Allentown’s 18101–18103 row-home alleys, and we’ve sourced and installed dozens of these custom configurations. Call (855) 938-5455 and we’ll measure your exact opening during a free estimate.
The gap is almost certainly from freeze-thaw heaving of your concrete threshold, not a defective door. Allentown’s repeated winter temperature swings lift and shift concrete aprons, particularly in older alleys with decades of salt exposure. Standard bottom seals can’t bridge these irregularities. We install threshold seal systems or grind the concrete flat before door installation to create a surface the seal can actually contact. This is a standard part of our alley-garage installations in central Allentown.
No. West End and other 18104 garages are typically attached to 1970s–1990s homes with standard 7’–8′ clearances, level concrete slabs, and modern dimensional lumber framing. The problems we solve there are different: aging torsion springs, obsolete openers, and doors that have simply reached end-of-life after 30–40 years. No custom sizing needed, no concrete grinding, no salt-corrosion mitigation. Two different neighborhoods, two completely different installation profiles.
Yes, and we do this regularly in Allentown’s older neighborhoods. The conversion requires removing the one-piece door and its pivot hardware, reinforcing or replacing the jambs, installing a new header support system for the sectional track, and often modifying the opening dimensions. We recently replaced a 1940s one-piece door on an alley garage in the 18102 district near Union Boulevard. The original operator was a long-obsolete model, and the concrete threshold had heaved two inches from freeze-thaw cycles. We installed a new Clopay steel door with a low-headroom track system and ground the apron flat so the bottom seal actually contacts the floor. Call (855) 938-5455 to discuss your specific conversion.
If your springs are original to a 1980s installation, they are already past their rated cycle life and could fail without warning. Torsion springs typically last 10,000 cycles — roughly 7–12 years for average use. A 40-year-old spring is a liability, not a component. When we install a new door on an older Allentown home, we always evaluate the spring system and typically recommend replacement as part of the installation to avoid a separate failure call within months. We can assess your springs during a free estimate — call (855) 938-5455.
