FAQs
I have a broken fence in Thornton. Do you also repair or install fences, or just garage doors?
Yes, we install and repair fences and gates as part of our services. Many homes in Thornton have aging wood or chain-link fencing that needs replacement or reinforcement. We can handle fence installation, manual or automatic gate installation, and custom metal fabrication. If your fence is sagging or your gate won't close, give us a call. We’ll inspect the issue and provide a straightforward repair or replacement option.
How do I know if I need a new garage door opener or just a repair?
If your opener makes grinding noises, doesn’t respond to the remote, or stops halfway, it might just need a repair. We can replace worn gears, sensors, or circuit boards. However, if the opener is over 10-15 years old, has a chain drive that’s very loud, or lacks safety features, replacing it with a modern belt-drive opener often saves money and improves performance. We’ll give you an honest assessment based on our inspection.
What brands of garage doors do you install, and do you offer insulated options?
We work with several reputable brands, including Clopay, Wayne Dalton, and Amarr. We offer both insulated and non-insulated doors. For homes in Thornton, an insulated steel door can help regulate garage temperature and reduce noise. We’ll help you choose a style and color that fits your home’s look and your budget. Our wholesale pricing means you get a quality door without the markup.
