"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Major Homes exceeded our expectations. Paul, in particular, stood out for his meticulous attention to detail and flexibility. He graciously scheduled our first meeting at a time that suited our convenience, where he went above and beyond to discuss industry standards and align them seamlessly with Major Homes' own high standards. His dedication to ensuring that every aspect of the project met our requirements was truly commendable. Anthony was exceptional in outlining the details and expectations for the execution of the contract. He provided clarity and assurance, laying the groundwork for a successful collaboration. What truly impressed me, however, was the performance of his crew. Their professionalism and dedication to delivering outstanding results were evident in every step of the project.

Windows questions, answered by experts

When it comes to your pocket, opting for energy-efficient windows can lead to an average of 12% in energy bill savings. That totals to yearly energy savings between $100 and $600. However, the exact amount you’ll save hinges on factors like your local climate and the number of windows in your home.

Garden windows last about 15 to 30 years, depending on the materials, ongoing maintenance, and local climate. Fiberglass and wood windows tend to have the longest life spans as long as you keep up with cleaning, lubricating, and refinishing them. Make sure to inspect your windows about once a year for signs of trouble, like worn-out seals, frame damage, or cracks in the panes.

The key difference between a hung window and an awning window is that hung windows (including single-hung and double-hung versions) slide vertically to open and close. In contrast, awning windows have a hinge at the top and open outward at an angle. You can use both types of windows throughout your home, but awning windows are best suited for kitchens and bathrooms.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.

Impact windows are a type of window made with impact-resistant glass, designed specifically for hurricanes. The glass, treated with ethylene-vinyl, can withstand winds up to 200 mph, as well as flying debris. Brands sometimes test their impact windows with large missile impact tests.

Impact windows may be required in some places. For instance, the Florida Building Code requires homes to have impact-resistant windows if they live within a mile of the coast where wind speeds can reach 110 mph or more.
