Transform Your Entryways with Professional Door Installation and Replacement in Southern NH
Your doors are more than just functional entry points they’re one of the first things visitors notice and a critical part of your home’s insulation and security. At McCarthy Exteriors, we specialize in professional door installation and replacement throughout Southern New Hampshire. Whether you're looking to upgrade a worn-out entry door, install a new patio sliding door, or improve your home’s energy efficiency, our team is here to deliver exceptional service and long-lasting results.
Our local team brings decades of experience to every door project, helping homeowners choose durable, stylish options that suit their homes and budgets. We work with top-rated manufacturers and handle every aspect of the installation process to ensure a perfect fit and optimal performance.
Entry Door Replacement That Enhances Security and Style
The front door is one of the most important features of your home’s exterior. It welcomes guests, protects your family, and contributes significantly to curb appeal. If your current door is drafty, outdated, or lacks the security features of modern doors, it may be time for a professional door replacement.
McCarthy Exteriors offers a wide range of high-quality entry door options, from classic wood to modern fiberglass and steel. Our door installation services include measuring, frame adjustment, insulation, and hardware replacement to ensure your new door operates flawlessly and lasts for years. Whether you’re going for a traditional New England look or a more contemporary style, we have the ideal entry door solution to complement your home.
You can also explore our full range of exterior renovation services to see how door replacement fits into a larger home improvement plan.
Sliding and Patio Doors Built for New Hampshire Living
Patio and sliding doors are popular features for connecting indoor living spaces to the outdoors. But when they become difficult to open, start leaking air, or develop foggy glass, it's time to consider a replacement. Our door installation and replacement team offers durable and energy-efficient sliding glass doors designed for the Southern NH climate.
Our patio doors come with options like double-pane glass, secure locking systems, and frames built to resist warping and moisture damage. We take precise measurements and ensure every sliding or French door we install glides smoothly, seals tightly, and enhances the natural light and beauty of your home.
As with all of our window replacement and siding upgrades, our door services are fully customized and backed by expert craftsmanship.
Energy Efficient Door Installation That Saves Money
Many older doors lack proper insulation and contribute to drafts, energy loss, and higher utility bills. McCarthy Exteriors installs energy efficient doors built to improve your home’s thermal performance while maintaining visual appeal.
We install doors with advanced weatherstripping, insulated cores, and tight-sealing frames that prevent air leaks and improve comfort. These doors are especially valuable in New Hampshire’s variable climate, where temperature swings between seasons can be extreme. A professionally installed energy efficient door will help keep your home warm in the winter, cool in the summer, and quiet all year round.
Upgrading to a new energy efficient door is also an investment that pays off in improved resale value and reduced maintenance.

Larry Bruno
Tyler and his crew were awesome to work with. They were efficient with all their work and materials and left a fantastic finished product. I would highly recommend them to any family or friends for any of their projects. I went with a Harie siding product on my home and was nervous of hiring a contractor that did not know what they were doing, but these guys put all my worries to rest on the first day.
Kristi Legere
