No — absolutely do not use a garage door with a broken spring. The spring system is what counterbalances the weight of the door. Without it, the door is extremely heavy and potentially dangerous, and attempting to open or close it can cause the door to drop suddenly, damaging the opener, bending tracks, or causing serious injury. Call Mastertech immediately for emergency spring replacement.

Yes. Our technicians are trained to repair virtually all major garage door opener brands including LiftMaster, Genie, Chamberlain, Craftsman, Sears, Linear, Marantec, Ryobi, and more. We carry replacement parts for most major brands on our service vehicles, which allows us to complete most repairs in a single visit.

This is usually a safety sensor issue. Modern garage door openers have photo-eye sensors near the floor on each side of the door. If they're misaligned, blocked, or dirty, the opener won't allow the door to close. Check that both sensor lights are solid (not blinking), that nothing is blocking the beam, and that the sensors are aimed at each other. If the problem persists, call us — sensor alignment and replacement is a quick, inexpensive fix.

A standard residential garage door installation typically takes 3–5 hours for a single car garage and 4–6 hours for a two-car garage. This includes removing the old door, installing the new door panels and hardware, setting up the track system, mounting and programming the opener, and testing all safety features. We complete most installations in a single visit.

The most common sizes are 8'x7' and 9'x7' for single-car garages, and 16'x7' and 18'x7' for double-car garages. The standard height is 7', though 8' tall doors are increasingly common in newer construction. For RV garages and commercial-adjacent applications, we can source doors in non-standard sizes. During your free estimate, our technician will measure your opening precisely to ensure a perfect fit.

New garage door costs vary significantly based on size, material, insulation level, and brand. A basic non-insulated single steel door starts around $500–$800 installed. A premium insulated double steel door from Clopay or Haas typically runs $1,200–$2,500 installed. Wood composite and custom doors can run higher. We'll give you a precise, itemized quote during your free estimate with no obligation.

Mastertech is an authorized dealer and installer for Clopay and Haas — two of the most respected names in the garage door industry. We do not install cheap contractor-grade doors from big box stores. Both Clopay and Haas offer extensive collections covering steel, wood composite, real wood, and aluminum options with comprehensive warranties.

We recommend having your garage door professionally inspected and tuned up at least once per year. Regular annual maintenance extends the life of your springs, cables, and opener significantly — and allows our technicians to identify and address minor issues before they become expensive repairs. A well-maintained garage door can last 20–30 years.

Our annual tune-up covers a full visual inspection of all mechanical and structural components, lubrication of springs, rollers, hinges, and tracks with professional-grade products, spring tension check and adjustment, safety sensor testing and alignment, opener force and limit setting verification, hardware tightening, and a written condition report. We check everything from weatherstripping to the auto-reverse safety function.

Yes — basic lubrication between professional visits is a good practice. Use a silicone or lithium-based spray lubricant (NOT WD-40, which is a solvent and can damage seals) on springs, rollers, hinges, and the opener rail. Avoid lubricating tracks — tracks should be clean and dry. Apply lubricant 1–2 times per year and after the door is exposed to extreme cold or heavy use. Our technicians are happy to show you the right spots and products during your annual tune-up.

A smart garage door opener connects to your home Wi-Fi and allows you to control your garage door from your smartphone — anywhere in the world. Through apps like LiftMaster myQ or Genie Aladdin Connect, you can open, close, check status, receive alerts, set schedules, and integrate with Amazon Alexa, Google Home, and Apple HomeKit. They're not essential, but for the relatively small price premium, the peace of mind of knowing your garage is closed from anywhere makes them very popular.

In many cases, yes. If you have a Genie opener manufactured after 1993, the Aladdin Connect retrofit kit adds full Wi-Fi capability without replacing the unit. LiftMaster also has add-on myQ modules for some models. During your service call, our technician can assess whether your opener is compatible with a smart upgrade or if a new opener would be more cost-effective.
