Door Installation Services in Nashville, TN

DEM Windows & Doors is a locally owned window and door contractor serving Nashville and the greater Middle Tennessee region across Davidson County and beyond. Your front door is the first thing visitors see and the first thing an intruder tests, so a worn, drafty, or hard-to-lock door is more than an eyesore. We handle professional door installation for homeowners who are tired of sticky doors that swell in the humidity, gaps that let the heat and cold pour in, dated entryways that drag down curb appeal, and locks that no longer feel secure. From entry and patio doors to full front door replacement, we install high-quality doors that combine durability, security, and energy efficiency, backed by free estimates and 100% financing.

Entry Doors

Strong, stylish, and secure front doors that set the tone for your home. We fit insulated steel and fiberglass entry doors that stand up to Nashville heat, cold, and humidity while adding real curb appeal.

Patio and Sliding Doors

Sliding and French patio doors that open your living space to the backyard and let in natural light. Energy-efficient glass and tight weatherstripping keep conditioned air inside where it belongs.

Storm and Security Doors

An added layer of protection and airflow. Storm and security doors shield your main door from wind-driven rain and give you an extra barrier against forced entry.

Interior Doors

Functional, stylish interior doors for every room, from bedrooms to closets to laundry rooms. We match the finish and hardware to the rest of your home.

Front Door Replacement in Nashville, TN

If your front door sticks in summer, rattles in winter, or shows daylight around the frame, it is time for a replacement. Front door replacement is one of the highest-value upgrades a Nashville homeowner can make, and it solves comfort, security, and curb-appeal problems in a single project. We remove your old door and frame, correct any rough-opening issues, and install a new insulated steel or fiberglass door that seals tight and locks securely.

This page is for installation and replacement. If your current door is in good shape and only needs a fix, a broken lock, a failing seal, or hardware that will not latch, our window and door repair team can help instead.

Nashville's Weather and What It Means for Your Doors

Nashville has a humid subtropical climate with hot, sticky summers and cold, sometimes arctic winters. Summer highs sit near 89°F with humidity that pushes past 65%, while winter can drop below freezing. That yearly swing expands and contracts your door, its frame, and its weatherstripping over and over. Gaps open up, and an old or poorly sealed door starts leaking conditioned air, which pushes your heating and cooling bills higher. The U.S. Department of Energy points to exterior doors as a real source of that air leakage and heat loss.

High summer humidity is just as hard on doors. It swells and warps solid wood slabs until they stick or stop sealing. Middle Tennessee also sees frequent severe weather. Tennessee averages around 21 tornadoes a year, plus damaging wind, hail, and flooding, and wind-driven rain finds every weak seal around a door.

DEM Windows & Doors installs insulated steel and fiberglass doors that resist humidity and warping far better than bare wood, and we offer ENERGY STAR certified options. Every install includes full weatherstripping, a sealed threshold, and precise measurement so the door fits tight to the jamb and holds its seal through every Nashville season.

Benefits of a New Door for Your Nashville Home

Stronger security

Your front door is the first thing a burglar tests, and the data backs that up. The front door is the single most common entry point in home break-ins, at roughly 34%, and more than half of burglaries involve forced entry, according to FBI and Bureau of Justice Statistics crime data. A hollow-core slab, a worn frame, or a basic knob lock is an easy target. We install solid steel and fiberglass doors with reinforced frames, heavy-duty strike plates, and multi-point locking options, and we anchor every door so the deadbolt seats fully into a reinforced jamb.

Lower energy bills

An old door leaks air in two ways, through worn weatherstripping and through the slab itself. That means drafts in winter, heat in summer, and an HVAC system that runs harder to keep up. ENERGY STAR certified doors are built to cut the air leakage and heat transfer that raise Nashville energy bills, and a tight, professional installation is what makes that rating hold up in the real world.

Higher home value

Replacing your front door is one of the smartest-value upgrades you can make. In the 2025 Cost vs. Value Report, a steel entry door replacement recouped about 216% of its cost at resale, ranking as the number two home improvement project in the country for return on investment. Buyers form an opinion of your home before they walk through the door, so a fresh, well-built entry door lifts curb appeal and resale value at the same time.
