We pride ourselves on the quality work we provide, while delivering great customer service! Call -or- click to schedule a free estimate today!

"We started out looking for an architect/designer, and met the owner of Tseranos Construction, Sterg, in the process. He referred us to a design architect, which we used, and we ended up then hiring Tseranos Construction as our general contractor. Sterg was really great to work with. He found ways to keep costs down while doing everything that we wanted to have done. In the end, the garage construction project took about 5 months, but we are thrilled with the results. Would hire Sterg again for future projects."

FAQs for garage door opener installation and replacement projects in Dover, NH

A chain-drive opener costs less, but it’s louder and needs more upkeep. If your budget allows, a belt-drive model is often the smarter long-term buy, especially for an attached garage with a bedroom above where noise matters. The decision between a chain or belt opener comes down to your budget and needs, and your garage door opener installer can help you choose an option that best suits you.

Choosing the right horsepower for your garage door opener is crucial for safe and efficient performance. Your garage door’s design and material determine the required horsepower. A single-car garage demands a half horsepower rating, while a two-car garage requires a rating between three-fourths and 1.25 horsepower. Selecting the proper power level ensures optimum performance and durability over the life of the opener.

Plan on a quick garage door tune-up once or twice a year. Tighten the chain or belt, lubricate moving parts, test the safety sensors, and swap out weak batteries in the remotes or backup unit. A few dollars in lubricant and 30 minutes of work can fend off costly repairs, keep the door running smoothly, and help the opener hit its full life expectancy.
