Replacement doors are designed to fit into existing frames, while new construction doors include complete frame assemblies for installation during building or major renovation. Replacement doors install faster with less disruption since they don’t require removing trim, siding, or interior finishes. New construction doors are necessary only when existing frames show severe damage or you’re changing door sizes significantly.

Replace doors showing frame rot, significant warping, failed insulated glass, or structural damage that repairs cannot adequately address. If your door is over 20 years old, replacement typically makes more economic sense than repairs since modern doors offer substantially better energy efficiency and security. We assess each situation to recommend the most cost-effective solution for your specific circumstances.

Replacement door costs typically range from $1,500 to $4,500 installed, depending on door type, material, size, and features. Entry door replacement generally costs $1,800-$3,500, while patio door replacement ranges $2,500-$5,000 for standard sizes. Impact-rated doors for hurricane protection add 25-40% to these base prices but provide essential protection for Florida coastal properties.

Many replacement projects replace only the door panel when existing frames remain structurally sound and properly aligned. However, if frames show damage, rot, or severe settling, full-frame replacement provides more reliable long-term results. We evaluate frame condition during consultation to recommend the best approach for your specific situation.

Professional installers typically complete entry door replacement in 3-6 hours, while patio door replacement may require a full day. Complex installations involving structural repairs, custom sizes, or multiple doors can extend across two days. We schedule installations to minimize disruption and ensure your home remains secure throughout the process.

Yes, replacing old doors with modern insulated units can reduce energy costs by 12-20% when doors were previously allowed significant air infiltration. Advanced weatherstripping, insulated cores, and Low-E glass in modern replacement doors dramatically outperform older products. Most homeowners notice immediate comfort improvements as drafts disappear and temperature consistency improves.

Fiberglass replacement doors offer the best overall value for St. Petersburg homes through superior insulation, complete moisture resistance, low maintenance, and authentic wood-grain appearance. Steel provides excellent security at lower prices but may rust in coastal environments. Vinyl works well for patio doors through weather resistance and affordability, though it offers fewer style options than fiberglass.

Quality replacement doors include manufacturer warranties covering materials and defects for 10-20 years or more, depending on brand and product line. We also provide installation workmanship warranties protecting against installation-related issues for specified periods. These combined warranties give you comprehensive protection for your investment.

Yes, many replacement door systems include coordinating sidelite and transoms that install together as complete entry systems. These combinations create impressive entryways with abundant natural light while maintaining security and energy efficiency. We help design entry configurations that maximize light and visual appeal within your existing opening dimensions.

Replacing all exterior doors simultaneously ensures a consistent appearance, maximizes energy savings immediately, and often reduces per-door costs through project efficiency. However, phased replacement allows spreading costs over time while addressing the most problematic doors first. We help you prioritize based on which doors need replacement most urgently and your budget considerations.
