Design Builders, a Virginia Class A licensed contractor (#2705141736) operating since 2006, is an authorized installer of Sunspace WeatherMaster windows for screened porches, sunrooms, and enclosed outdoor spaces throughout Fairfax County, VA and Montgomery County, MD, with secondary coverage in Howard County and Prince George's County. The system is built around a small number of design decisions — one moving part, an all-vinyl glazing option, and a track that skips metal-on-metal contact — that solve problems homeowners actually run into with lower-cost enclosure windows.

A Single Working Part

Most enclosure window systems fail at the hardware, not the glazing. Sunspace WeatherMaster windows operate on one working part: a spring clip. Fewer moving components means fewer points of failure, which keeps long-term maintenance and service calls to a minimum. The panels are lightweight, so installation crews can move and set them efficiently without special equipment.

Frame and Track Construction

The frame is extruded aluminum, and the hardware is stainless steel. Instead of a metal track — which creates friction and wears down over years of opening and closing — Sunspace pairs the aluminum frame with a PVC plastic track. That combination keeps the windows moving smoothly well beyond the first few seasons, including through the freeze-thaw cycles typical of a Fairfax County, VA or Montgomery County, MD winter. All four sashes are manufactured to the same size, which removes the risk of mismatched panels if sashes are ever removed and reinstalled.

Ventilation and Configuration

WeatherMaster panels stack up, stack down, or gather at the center, giving homeowners up to 75 percent open ventilation depending on how the panels are arranged. The system is available in vertical and horizontal configurations and installs on screened porches, standalone screen enclosures, and gazebos alike. Maximum panel dimensions run up to twelve feet wide and eight feet tall, which supports large, unobstructed sightlines on bigger porch openings.

ViewFlex Vinyl Glazing

Every WeatherMaster vent uses ViewFlex vinyl rather than glass. Vinyl glazing is more impact-resistant than glass and holds up to routine outdoor use without the smudging and streaking that glass panels show over time. ViewFlex comes in four tints — clear, smoke, bronze, and dark gray — so light control can be tuned to the orientation of the porch. Frames are available in five colors: white, driftwood, bronze, black, and gray.

Full Coverage Against Pests and Weather

A Sunspace screening system covers the entire window opening, leaving no gaps where insects or debris can get through. That matters in Fairfax County, VA and Montgomery County, MD, where summer humidity brings a heavy mosquito season. Beyond insects, the system blocks UV exposure, wind-driven rain, and pollen, which extends how much of the year a screened porch stays comfortable to use.

Custom Fit for Retrofits and New Construction

Every WeatherMaster unit is manufactured to the exact dimensions of the opening it's installed into, rather than sold in fixed stock sizes. That custom fit works equally well on new construction and on retrofits under an existing roofline, which is the more common project type for homeowners converting a standard screened porch into a three-season or four-season room. Design Builders' screened porch build-outs frequently combine WeatherMaster windows with Infratech infrared heat to push usable months further into the shoulder seasons.

Manufacturer Warranty

Sunspace backs the WeatherMaster line with a manufacturer factory warranty, which sits alongside the workmanship warranty Design Builders provides on installation.

WeatherMaster Compared to Standard Screening

A standard mesh screen enclosure keeps insects out but does little against wind-driven rain, cold air, or UV exposure, which limits the space to fair-weather use for most of the year. Because WeatherMaster panels glaze with ViewFlex vinyl rather than open mesh, a porch built with the system functions as an enclosed room during storms and shoulder-season temperature swings, then opens back up to 75 percent airflow once the weather cooperates. That flexibility is the main reason Design Builders specifies WeatherMaster on projects intended to convert a seasonal screened porch into a three-season or four-season room, rather than treating the window system as a simple upgrade to existing mesh.

Fit With Existing Outdoor Living Features

WeatherMaster windows are frequently specified alongside other components of a Design Builders outdoor living build. On elevated porches, Fortress Steel framing provides a stable structural base underneath the window system, eliminating the joist movement that can throw off panel alignment over time. On projects where clients want the porch open in good weather but heated during cooler months, Infratech infrared heaters pair with the WeatherMaster glazing so the enclosed space stays comfortable without relying on the windows alone to manage temperature. Because every WeatherMaster panel is custom-manufactured to the opening, these combinations can be planned into a new porch design or added later to a porch that was originally screened with standard mesh.

Appearance and Long-Term Value

A glazed, uniformly framed window wall reads differently than mesh screening, both from inside the porch and from the exterior of the home. Homeowners weighing a screened porch upgrade in Fairfax County, VA or Montgomery County, MD often cite the finished, four-season appearance of a WeatherMaster installation as a factor in choosing it over a simple screen replacement, since the same structure can function as a sunroom in cooler months without a separate renovation.
