WINDOW REPLACEMENT NEEDS
When To Replace Your Windows in Lewes
Windows affect comfort, ventilation, natural light, and protection around the exterior opening. As windows age, worn seals, damaged components, or movement around the frame can make them difficult to operate and more vulnerable to air or water infiltration.
Lewes homes can also experience moisture, strong sun, wind-driven rain, humidity, and seasonal temperature changes. These conditions can expose weaknesses in older windows and the surrounding trim or opening.
Platinum Roofs evaluates the visible condition of the window and the materials around it before determining whether replacement is appropriate. You may need a window assessment when:
Closed windows allow noticeable drafts
Glass is fogged or cloudy between the panes
Windows stick, bind, or no longer close securely
Frames, sashes, or exterior trim show deterioration
Water staining or soft materials appear around the opening

WINDOW INSTALLATION
What Window Installation and Replacement Includes
A replacement window must fit the opening correctly and connect properly with the surrounding exterior. Even a well-made window can develop drafts or water problems when the opening, flashing, sealing, trim, or installation details are not handled correctly.
Platinum Roofs reviews the existing window and helps homeowners compare relevant features and material options. The recommended installation approach depends on the condition of the window, frame, opening, and surrounding materials.
The goal is a properly installed window that operates as intended and supports the home’s comfort, weather protection, appearance, and energy performance.
Evaluating the existing window and opening
Reviewing window features and material options
Removing eligible existing window components
Inspecting the opening for visible damage
Installing, securing, sealing, and testing the new window
Coordinating exterior trim and surrounding finishes
PROJECT PLANNING
Planning a Window Project in Lewes
Window replacement may involve more than removing one unit and installing another. The condition of the frame, rough opening, exterior trim, siding, interior finishes, and water-management details can all affect the project scope.
Platinum Roofs also accounts for the property location and the extent of the work. Inside the City of Lewes, renovation work may require City review. Properties in the Historic District can require additional approval, particularly when exterior appearance is being changed. Requirements outside City limits depend on the project scope and applicable Sussex County rules.
Related exterior openings can be addressed through our door installation service. Homeowners planning several exterior improvements can also review our complete exterior services.

Frequently Asked Questions
How do I know if my windows need to be replaced?
Signs can include drafts, fogging between panes, difficulty opening or closing, damaged frames, loose components, exterior deterioration, or water staining around the opening. Platinum Roofs evaluates the windows and surrounding conditions before recommending replacement.
Do drafty windows always need to be replaced?
Not always. A draft may come from worn weatherstripping, failed seals, gaps around the trim, poor installation, or deterioration within the window. The cause should be evaluated before deciding whether repair or replacement is appropriate.
What does condensation between window panes mean?
Moisture or fogging trapped between panes often indicates that the sealed glass unit has failed. Condensation on the room-facing surface can also be related to indoor humidity, ventilation, or temperature differences, so the location of the moisture matters.
Can replacement windows improve energy efficiency?
They can improve energy performance when the product is appropriate for the climate and the window is installed and sealed correctly. Performance varies based on the glass, frame, air leakage, product ratings, existing conditions, and installation. ENERGY STAR recommends selecting products certified for the applicable climate zone and following the manufacturer’s installation requirements.
Can window replacement help stop drafts and water leaks?
Properly fitted and sealed replacement windows can address problems caused by failed windows or installation gaps. Water may also be entering through damaged trim, siding, flashing, roofing, or other exterior components, so the source should be evaluated first.
What happens if water damage or rot is found around the window?
Deteriorated materials should be addressed before the new window is fully installed and finished. Platinum Roofs evaluates the visible condition of the opening and explains any additional preparation needed for the project.
Can replacement windows be installed in the existing opening?
Often, yes. The existing opening must be suitable for the selected window and installation method. Damage, movement, an altered layout, or a change in window size may require more extensive preparation.
Do I need a permit for window replacement in Lewes, DE?
Requirements depend on the property location and project scope. Sussex County lists replacement of two or fewer existing windows among projects that do not require a County permit, but municipal requirements can still apply. Inside the City of Lewes, renovation work may require City review, and Historic District properties may require additional approval. Platinum Roofs helps account for the requirements that apply.
How long does window installation take?
The schedule depends on the number of windows, access, window sizes, opening conditions, necessary preparation, trim work, and whether hidden damage is discovered. Platinum Roofs reviews the project before providing a schedule.
How much does window installation cost?
Cost depends on the number and size of the windows, selected features, material options, access, opening condition, trim, necessary repairs, and installation complexity. An assessment is needed before an accurate proposal can be prepared.
How does Platinum Roofs help me choose replacement windows?
