Frequently asked questions
Everything you need to know before starting this project.
Replacing the bottom astragal seal averages $120 installed, ranging $75–$220 based on door width and whether the retainer needs work. The rubber itself is inexpensive; labor and access drive the cost. Double doors cost a bit more than singles.
Look for cracks, flattening, gaps that let in light, water, drafts, or pests, and pieces that no longer flex. A worn seal often lets leaves and rain into the garage. Replacing it restores a tight, weatherproof closure.
Common profiles include T-style, bead-style, and P-bulb seals that slide into an aluminum retainer on the door bottom. The retainer shape determines which seal fits. Bringing a sample or measuring the retainer ensures the correct match.
Sliding a new seal into an existing retainer is a manageable DIY task with lubricant and a helper for wider doors. If there is no retainer or it is damaged, professional installation is easier. Correct sizing is key to a leak-free result.
