Frequently Asked Questions – Door Hardware
What types of door hardware do you install?
We install a wide range of locksets and door hardware from trusted manufacturers, including entry handles, deadbolts, interior knobs and levers, and specialty hardware for bathrooms and closets.
Can I match my door hardware to my home’s style?
Yes! We offer a variety of finishes—like matte black, satin nickel, and oil-rubbed bronze—to complement everything from rustic cabins to modern homes.
Is your hardware secure?
Absolutely. We only install products that meet high standards for durability and security. If you’re looking for smart lock options or enhanced deadbolt systems, we can help with that too.
Do I need to replace all my door hardware at once?
Not necessarily. Many homeowners start with high-traffic areas like front entries or bathrooms and update other doors over time. We’re happy to help you plan based on your needs and budget.
How long does installation take?
Most door hardware installations can be completed in a single visit. We’ll schedule a time that works for you and make sure everything is installed cleanly and correctly.
Do you offer warranties on your work?
Yes! We stand behind our workmanship and the products we install. If you ever have an issue, just give us a call—we’re here to help.
