Northern California Commercial Refrigeration Specialists
Walk-In Freezer Gasket Replacement Done Right — the First Time
A failing walk-in freezer gasket causes frost buildup, compressor overwork, and rising energy costs — often without obvious warning signs. Cal Gaskets custom-makes and installs premium sub-zero-rated freezer door gaskets, fabricated to fit your unit and installed by certified technicians who get it right the first time.

The Hidden Cost of a Bad Seal
What Happens When Your Walk-In Freezer Gasket Fails
Freezer gasket failure is harder to spot than a cooler gasket problem — until it isn't. The consequences at sub-zero temperatures are faster, more severe, and more expensive to recover from.
Frost and Ice Build Up Around the Door
A failing freezer gasket lets warm, humid air infiltrate continuously. That air immediately freezes on contact with cold surfaces, building up frost and ice around the door frame — and in serious cases, causing the door to partially freeze shut during overnight hours.
Your Compressor Never Gets a Break
Walk-in freezers already demand more from their compressors than coolers. A failed gasket compounds that — the unit has to work constantly to compensate for warm air leaking in at sub-zero temperatures, accelerating wear on the most expensive component in the system.
Frozen Inventory at Risk
When a walk-in freezer can't hold its target temperature reliably, your frozen product is at risk. Partial thaw-and-refreeze cycles degrade food quality and can create compliance issues with health inspectors who check product temperatures closely.
Energy Bills Rise Quietly
A compromised freezer seal bleeds energy around the clock. Because the cost increase is gradual, it often goes unnoticed for months — but the cumulative impact on your energy bill can be substantial, especially in a high-use food service environment.
Our Service
Custom Walk-In Freezer Gaskets, Installed by Certified Technicians
At Cal Gaskets, commercial refrigeration sealing is all we do. Walk-in freezer gaskets are one of the most demanding applications in the food service world — they operate at sub-zero temperatures, cycle through extreme thermal changes with every door opening, and are expected to maintain an airtight seal around the clock. We use commercial-grade materials specifically rated for freezer environments, custom-fabricated to the exact dimensions of your door — not pulled off a shelf and forced to fit.
Before we install, our certified technicians assess the full door frame, the condition of the retainer channel, and the anti-sweat heater wire that runs around the freezer door frame. A failed heater wire is a common secondary issue that accelerates gasket wear — and one that many general repair services miss entirely.
Sub-Zero Rated Materials
Not all gasket materials perform reliably at freezer temperatures. We use commercial-grade compounds specifically selected for sub-zero environments — materials that maintain flexibility and seal integrity at -10°F and below, not just cooler temperatures.
Custom-Fabricated to Your Unit
Every walk-in freezer gasket we make is custom-fabricated to the precise dimensions of your door. No universal fits, no forcing a standard size into a non-standard frame. If your unit is older or non-standard, we can still get it right.
Full Door Frame Assessment
Before installation, our certified technicians inspect the full door frame, closure system, and anti-sweat heater wire. A new gasket on a damaged frame or failed heater wire is a short-term fix — we catch secondary issues before they undermine the work.
Certified Professional Installation
Freezer gasket installation has less margin for error than a cooler — improper seating can result in immediate frost infiltration. Our technicians are trained specifically for commercial refrigeration sealing and get it right the first time.

Common Questions
Common Questions About Walk-In Freezer Gaskets
The most common signs are frost or ice buildup around the door frame, a door that feels stiff or freezes partially shut, or visible cracking and brittleness in the gasket itself. At freezer temperatures, gaskets degrade faster than on cooler units — the extreme cold causes the material to harden and lose its flexibility over time. If you can see daylight around any part of the door seal, or if your compressor seems to be running almost constantly, those are strong indicators the gasket has failed.
Keep Your Walk-In Freezer Sealed, Your Compressor Protected, and Your Inventory Safe
A walk-in freezer gasket inspection costs you nothing. What it gives you is certainty — about the state of your seals, your energy efficiency, and your compliance standing. Our certified technicians will assess your door gaskets and heater wire, give you an honest evaluation, and recommend only what's actually needed.
No pressure. No obligation. Just a straight answer from specialists who know walk-in freezer gaskets better than anyone in Northern California.
