What brands of garage doors do you install?

We install and service all major garage door brands including Clopay, Amarr, Wayne Dalton, CHI Overhead Doors, Raynor, and many more. We're not exclusive to any single manufacturer, which means we can recommend the best door for your specific needs and budget. Whether you're looking for a budget-friendly steel door or a premium custom wood carriage door, we have options. Our team can show you samples and help you choose colors, styles, and features that complement your home's architecture.

How long does a garage door installation take?

A standard garage door installation typically takes 3-5 hours, depending on the complexity of the job. This includes removing your old door (if applicable), installing the new door and hardware, mounting the opener, programming remotes, and testing everything to ensure proper operation. Custom doors or unusual configurations may take longer. We always aim to complete installations in a single visit so you're not left without a functioning garage door. We'll provide a time estimate during your consultation.

Do you offer warranties on your work?

Yes! We provide a comprehensive 2-year warranty on all labor and installation work. Additionally, most garage doors come with manufacturer warranties ranging from 3 years to lifetime coverage depending on the model and brand. Our warranty covers any defects in workmanship, and we'll return to make things right at no additional cost if any issues arise from our installation or repair work. This warranty is part of our 100% satisfaction guarantee.

What maintenance does a garage door need?

Regular maintenance extends the life of your garage door and prevents costly repairs. We recommend: lubricating moving parts (hinges, rollers, tracks) every 3-4 months with a silicone-based lubricant; checking and tightening hardware annually; testing the auto-reverse safety feature monthly; visually inspecting springs, cables, and rollers for wear; and cleaning the tracks of debris. We offer annual maintenance packages that include a comprehensive safety inspection, lubrication, adjustment of springs and cables, and testing of all safety features.

Why is my garage door making noise?

Noisy garage doors are one of our most common service calls. The noise can come from several sources: worn rollers (especially older nylon or steel rollers), loose hardware that vibrates, lack of lubrication on moving parts, worn-out springs, or an aging chain-drive opener. Squeaking usually indicates a need for lubrication, while grinding or scraping sounds suggest alignment issues or worn parts. Banging or popping can mean loose hardware or springs under tension. We diagnose the exact cause and provide targeted repairs rather than replacing parts unnecessarily.

Can you fix a dented garage door?

It depends on the severity and location of the dent. Minor dents can often be repaired using specialized techniques that restore the panel's appearance. For more severe damage, or dents in structural areas, panel replacement is usually the better option. We carry common panel sizes in our service vehicles, allowing us to complete many panel replacements the same day. If your door has multiple damaged panels or is an older model, we'll discuss whether repair or replacement makes more economic sense for your situation.

Is it safe to replace garage door springs myself?

We strongly advise against DIY garage door spring replacement. Garage door springs are under extreme tension—a standard torsion spring for a two-car garage can hold 200+ pounds of force. If a spring snaps or is improperly installed, it can cause serious injury or death. Every year, emergency rooms treat thousands of injuries from DIY garage door repairs. Our technicians have specialized training and tools for safe spring replacement. The cost of professional spring replacement is modest compared to the risk of serious injury.

What's the difference between torsion and extension springs?

Torsion springs are mounted above the garage door on a metal shaft and use torque to lift the door. They're more expensive but last longer (15,000-20,000 cycles vs 10,000 for extension springs), operate more smoothly, provide better balance, and are safer when they break. Extension springs run along the horizontal tracks on either side of the door and stretch to provide lifting force. They're less expensive upfront but wear faster and can be dangerous if they snap without proper safety cables. We typically recommend torsion springs for their safety and longevity benefits.

How do I know when to replace my garage door?

Consider replacement if: your door is more than 20-25 years old; you're experiencing frequent breakdowns that are costing more in repairs than a new door would; the door is visibly damaged, warped, or sagging; it lacks modern safety features; your energy bills are high due to poor insulation; or you're planning to sell your home and want to boost curb appeal (garage doors offer one of the highest ROIs for home improvements). We provide free consultations to assess your current door and discuss whether repair or replacement makes the most sense.

Do you work on commercial garage doors?

Yes! While our primary focus is residential service, we also work on commercial and industrial garage doors. This includes rolling steel doors, sectional overhead doors, high-speed doors, fire-rated doors, and loading dock equipment. Commercial doors often have different requirements than residential—higher cycle ratings, heavier construction, and specialized safety features. We have experience with retail storefronts, warehouses, fire stations, and other commercial properties throughout our service area.

How quickly can you fix my damaged panels?

We understand that damaged panels are both an eyesore and a security concern. In most cases, we can repair or replace damaged panels within 24-48 hours. For emergency situations where your garage door is inoperable or poses a security risk, we offer same-hour emergency service. Our technicians arrive with a fully stocked van carrying common panel sizes and hardware, allowing us to complete many repairs in a single visit. For specialty or custom panels that need to be ordered, we'll provide a temporary solution to ensure your home remains secure while we await the replacement parts, typically arriving within 3-5 business days.

What causes damaged panels in garage doors?

Garage door panels can become damaged from several common causes. The most frequent is accidental impact from vehicles backing into the door, which accounts for about 40% of panel damage we see. Weather-related damage is another major factor, especially in New Hampshire where harsh winters, heavy snow loads, and ice accumulation can warp, crack, or dent panels. Age and wear also play a significant role—older panels made from thinner gauge steel or untreated wood are more susceptible to rust, rot, and deterioration. Other causes include children playing near the door, windblown debris during storms, failed springs causing the door to slam down, and improper installation that creates stress points. Regular maintenance and inspections can help identify early warning signs before minor issues become major damage.

Do you offer financing for new contemporary door installations?

Yes! We understand that a new contemporary garage door installation is a significant investment in your home. That's why we offer flexible financing options to fit various budgets. We partner with several reputable financing companies to provide options including 0% APR for qualified buyers on terms up to 18 months, low monthly payment plans extending up to 60 months, no money down options for approved credit, and special financing for homeowners with less-than-perfect credit. During your free consultation, our team will discuss all available financing options and help you find the plan that works best for your situation. A new contemporary garage door not only enhances your home's curb appeal but can also increase energy efficiency and property value—making it a smart investment regardless of how you choose to finance it.

Garage Door Photo Eye Safety in Wentworth, NH: Why This Sensor Matters More Than You Think

2026-07-15 7 min read A2Z Garage Doors

Your garage door photo eye is a small sensor that prevents crushing injuries and property damage. If it's blocked, misaligned, or malfunctioning, your garage door loses its ability to reverse when something is in the way. In our years serving Wentworth, we've seen this problem again and again: homeowners ignore a blinking photo eye, a child or pet gets trapped, and suddenly it becomes an emergency call.

What Is a Garage Door Photo Eye and Why Does It Matter?

A photo eye (also called a photoelectric sensor) is an infrared beam that runs across the bottom of your garage door opening, about 6 inches above the floor. One sensor emits a beam; the other receives it. When the beam is broken by an object, pet, or person, the garage door opener is programmed to stop and reverse direction. This auto-reverse feature is not a luxury. It's a safety requirement mandated by federal law since 1993.

Without a functioning photo eye, your garage door won't detect obstacles. A 400-pound door descending at full force can cause serious injury or death. We've responded to calls where a child was nearly trapped, a pet was struck, or a vehicle was crushed. All of these incidents could have been prevented with a working photo eye.

Common Photo Eye Problems in Wentworth

Wentworth's weather and terrain create specific challenges for photo eye sensors. Dust, pollen, and moisture accumulate on the lens, blocking the infrared beam. Winter salt spray corrodes the sensor housing. Vibration from heavy traffic or nearby construction can knock sensors out of alignment by even a fraction of an inch. Once misaligned, the beam doesn't connect, and your door won't function properly.

Another common issue: homeowners don't realize their photo eye is failing. Warning signs include a garage door that reverses on its own, won't close all the way, or closes then immediately reopens. Many people assume the door is just "acting up" and live with it. That's when accidents happen.

We recommend checking your photo eyes monthly. Look for a small red or green light on each sensor. If one light is off or dim, the beam is broken. You can also wave your hand across the sensors while the door is closing. The door should stop and reverse immediately.

How to Keep Your Photo Eyes Working

Start with cleaning. Use a soft, dry cloth to gently wipe each sensor lens. Never use water or harsh chemicals. If dust or debris persists, a small amount of rubbing alcohol on the cloth is safe. Do this every two months, especially during fall and spring when pollen is highest.

Check alignment quarterly. Both sensors should have their red or green indicator light on. If one is dark, the beam isn't reaching it. You can use a piece of tape to gently adjust the sensor bracket left or right until the light comes on. If adjustment doesn't work, the sensor itself may be damaged and needs replacement.

Keep the sensors clear of obstructions. Cobwebs, mud splatter, and snow can block the beam just as easily as a hand or toy. Before closing your garage door in winter, check that the sensor area is clear of ice or snow buildup. If you live near trees, trim branches that might hang over the sensor opening.

When Photo Eyes Fail: What Happens Next

If your photo eyes aren't working, your garage door opener will go into a "safety lockout" mode. Many modern openers won't allow the door to close at all if the photo eyes fail. Some older openers will still close the door, which is why this safety feature is so critical. A door that closes without sensing obstacles is a serious hazard for child safety and pet protection.

Replacing photo eyes typically costs between $150 and $300 per pair, depending on the opener brand and sensor type. This is far cheaper than hospital bills or property damage from a runaway door. If your photo eyes are failing, schedule a free quote from our team and we can assess your system same-day.

If your door is reversing unexpectedly or won't close, don't assume it's a minor problem. Read our guide on troubleshooting common garage door repair issues in Wentworth to see if photo eye misalignment is the culprit.

Frequently Asked Questions

How do I know if my photo eye is blocked? Look for a dark or flickering indicator light on the sensor. If the red or green light is off, the beam is broken. You can also test by waving your hand across the sensor while the door is closing. The door should stop and reverse instantly.

Can I clean my own photo eyes? Yes. Use a soft, dry cloth to gently wipe each lens. Avoid water or harsh chemicals. Clean every two months, especially in dusty seasons. If cleaning doesn't restore the light, the sensor may need replacement.

What does it cost to replace photo eyes? Most photo eye replacements run $150 to $300 per pair, depending on your opener brand and sensor type. We provide free estimates. Call 1-978-440-2999 for pricing on your specific system.

Will my garage door close if the photo eye fails? Modern openers won't allow the door to close if photo eyes fail. Older systems may close anyway, which is dangerous. This is why testing your sensors regularly matters so much.

How often should photo eyes be tested? Check them monthly visually and clean them every two months. Have a professional inspection annually as part of routine garage door maintenance.
