How often should I have my garage door serviced?

We recommend having your garage door professionally serviced at least once a year. Regular maintenance helps prevent unexpected breakdowns, extends the lifespan of your door and opener, and ensures safe operation. During a maintenance visit, our technicians inspect all components, lubricate moving parts, test safety features, and make necessary adjustments. If you use your garage door heavily (more than 4 times per day), consider scheduling maintenance every 6 months.

What are signs that my garage door springs need replacement?

Several signs indicate your garage door springs may need replacement: the door feels unusually heavy when lifting manually, you hear loud creaking or popping noises during operation, the door opens unevenly or appears crooked, there's a visible gap in the spring coils, or the door won't stay open when raised halfway. Springs typically last 7-10 years or about 10,000 cycles. If you notice any of these signs, contact us immediately—broken springs can be dangerous and should only be handled by professionals.

In our years serving Waltham, we've seen this problem again and again: homeowners notice drafts around their garage doors, energy bills creeping up, or worse.mice and insects getting inside. The culprit? Deteriorated weather stripping and seals. Replacing them is one of the smartest maintenance moves you can make, and it costs far less than heating or cooling wasted air.

Why Weather Stripping Fails in Waltham

New England winters are tough on garage doors. Freeze-thaw cycles cause rubber and vinyl seals to crack, shrink, and separate from the door frame. By spring, a seal that looked fine in November is brittle and useless. Summer heat accelerates the breakdown too.UV exposure hardens materials over time.

The bottom seal takes the most abuse. It's in constant contact with the garage floor, accumulating dirt, salt residue, and moisture. Over 3 to 5 years of Waltham weather, even quality seals lose their elasticity and stop creating an airtight barrier.

Side seals and the threshold strip around your door frame deteriorate at similar rates. If you've noticed a visible gap where light comes through, or felt a draft during our cold months, your seals are almost certainly worn out.

What Happens When Seals Fail

A failing seal does more than make your garage uncomfortable. It lets conditioned air escape.heating in winter, cooling in summer. Studies show that a compromised door seal can account for 10,15% of garage heating loss. Over a heating season, that's real money leaving your home.

Beyond energy waste, gaps invite unwanted guests. Rodents, insects, and other pests exploit even small openings. Once inside, they nest in insulation, chew wiring, and create health hazards. Prevention through proper sealing is infinitely easier than dealing with an infestation.

Water infiltration is another hidden cost. Rain and snow melt seep past worn seals, damaging flooring, stored items, and the garage structure itself. Waltham's wet springs and fall rains make this especially relevant for our climate.

Types of Garage Door Seals and Which You Need

Most doors have three seal zones: the bottom seal, side seals, and the top seal. Each serves a distinct purpose and fails independently.you might replace just the bottom seal one year and the sides the next.

Bottom seals are the most visible and replaceable. They mount to the bottom edge of the door and compress against the concrete floor. Vinyl and rubber options exist; rubber generally lasts longer but costs slightly more.

Side seals (also called edge seals) run vertically along the left and right sides of the door frame. They're often overlooked but crucial for stopping lateral drafts. Installing them correctly requires precise measurement and careful fitting.

Threshold seals sit on the garage floor itself, creating a barrier where the door meets the slab. They're separate from the door and easy to replace.a good place to start if you're budget-conscious.

If you're unsure which seals your door has, or which ones need attention, our team at Garage Door Waltham can assess the condition during a free estimate. We'll identify problem areas and recommend the right solution for your specific door and budget.

Cost and Installation Timeline

When to Call a Professional
