** The window replacement and installation market in Wilmington, Delaware, is competitive and served by a mix of large national contractors and long-standing local companies.

Quality is generally high among the top-tier providers, with a strong focus on vinyl windows for their durability and energy performance. Competition helps keep pricing in check, but consumers will find a range.

Get answers to common questions about windows services in Wilmington, Delaware.
For a standard vinyl double-hung window replacement in Wilmington, homeowners can expect to pay between $600 and $1,200 per window, including professional installation. The total project cost depends on the number of windows, the style (e.g., picture, bay, or casement), and the material (vinyl, wood, fiberglass). Regional factors like Delaware's 0% sales tax on home improvements can help keep the final price closer to the estimate, but labor costs in the Wilmington area are a significant component.
Wilmington's humid summers and cold, windy winters make energy efficiency a top priority. We strongly recommend windows with Low-E glass and argon gas fills to manage heat gain in summer and retain heat in winter. Given the area's exposure to coastal storms and nor'easters, look for windows with a high Design Pressure (DP) rating to ensure they can withstand strong winds and driving rain common in New Castle County.
Yes, a building permit from the Wilmington Department of Licenses and Inspections is typically required for window replacements that alter the structural opening. This is especially critical if you live in a designated historic district like Quaker Hill or the Trinity Vicinity, where the Historical Commission must approve any changes to the window's style, material, or appearance to maintain architectural integrity.
While installations can be performed year-round, the ideal windows are late spring (April-May) and early fall (September-October). These periods offer mild, dry weather that is optimal for sealing and allows for proper curing of caulking and insulation. Scheduling during these shoulder seasons also helps you avoid the busy summer peak and the potential for winter installation delays due to ice or extreme cold along the I-95 corridor.
Always verify that the company is licensed and insured in Delaware and check for positive reviews on local platforms. A reputable Wilmington installer should provide a detailed, in-home estimate (not just a phone quote) and be knowledgeable about local building codes and historic district requirements. Ask for proof of local projects and references, and ensure they offer a strong warranty that covers both the product and their labor against Delaware's seasonal weather stresses.
