Portland, ME's Trusted Door Installer Since 1978
WeatherMaster Door Installation in Portland, ME
A porch enclosure or sunroom is only complete with the right entry door. The Sunspace Vertical 4-Track Entry Door is custom-built to match your WeatherMaster window system exactly, unifying the look and function of your entire enclosure from frame to threshold.
Why Your Door Matters as Much as Your Windows
A Mismatched Door Undermines the Whole Enclosure
100%
of the WeatherMaster door is pre-assembled before it arrives at your home. Every threshold, hinge, gasket, and window panel is factory-fitted and pre-squared for a water and air-tight result from day one.
A standard exterior door installed into a WeatherMaster porch enclosure or sunroom looks and performs like an afterthought. It breaks the visual continuity of your window system, creates potential leak points at the frame connections, and introduces hardware that will not hold up to Maine’s coastal conditions.
The Sunspace Vertical 4-Track Entry Door is built on the same premise as the WeatherMaster window, giving you a single, unified system where every component matches in color, profile, and performance.
Seamless Visual Integration
Built on the same profiles as the WeatherMaster window system, the entry door looks like a natural part of your enclosure, not an addition bolted on afterward.
Water and Air-Tight Construction
Double gaskets and pre-squared frames seal every connection completely, keeping Maine's rain, wind, and coastal humidity outside where they belong.
Stainless Steel Heavy-Duty Hinges
Stainless steel hinges with backer plates prevent sagging over time, ensuring smooth, reliable operation through Maine's freeze-thaw cycles and coastal conditions.
Custom-Built to Your Opening
Available in widths from 24" to 42" and heights from 60" to 96", the door is sized to your exact opening, not adapted from a standard size.
Arrives Fully Assembled
Pre-installed thresholds, pre-squared frames, and factory-fitted hardware mean your door arrives ready to install without on-site adjustments or modifications.
Added Home Value
A unified, professionally installed enclosure with a matching entry door elevates the finished quality and resale appeal of your outdoor living investment.

Common Questions
WeatherMaster Door Installation FAQs
Everything Portland homeowners ask before scheduling their first consultation.
The Sunspace Vertical 4-Track Entry Door is a custom-built entry door used in sunroom and porch enclosure applications. It is built on the same profiles as the WeatherMaster window system, with a pre-installed ViewFlex vinyl vertical 4-track window panel, pre-squared aluminum frame, double gaskets, and stainless steel hinges. Every unit arrives fully assembled with threshold pre-installed, ready for your crew to fit directly into your enclosure frame.
Standard and custom widths are available from 24" to 42" and heights from 60" to 96". The knee wall height is also fully customizable to match your window system and your aesthetic preference. Contact us to discuss any opening that falls outside these standard ranges.
The Single V4T Door is a standard single-swing entry door suited to most porch enclosure and sunroom openings. The French Garden V4T Door is a double-swing configuration designed for wider openings or homeowners who want a more architectural entry statement. Both configurations include the same pre-installed ViewFlex window panel, custom sizing, and hardware options.
Four hardware finishes are available: Satin Silver, Oil Rubbed Bronze, Antique Brass, and Bright Brass. Your consultant will help you select the finish that best matches your existing exterior hardware or interior aesthetic

Our consultants assess your existing frame during the free consultation to confirm compatibility and the right attachment method.
Yes, and this is one of its primary design advantages. The Vertical 4-Track Entry Door is built on the same profiles as the WeatherMaster window system, so the door and windows share the same frame color, vinyl tint, and visual profile across your entire enclosure. The result is a unified appearance rather than a mismatched entry point.
Absolutely. A WeatherMaster entry door pairs naturally with a porch enclosure installation, a sunroom installation, or a deck installation beneath the entry threshold. We can scope and manage any combination as a single, coordinated project.
