Paragon

A loose seal invites bigger damage

A basement suite in this area sits low to the ground, so runoff and damp air funnel toward the entry. Once that moisture works past a loose door, it swells the frame and softens the trim, making each opening feel less secure.

A well-fitted entry enhances curb appeal and creates a welcoming atmosphere. In this climate, that first step down should feel as confident as the main entrance above, not like an afterthought.

A Dry, Secure Suite Entrance

A basement suite entrance that drafts and shakes in the wind is not just uncomfortable; it shows your home’s exterior is failing. Paragon Exteriors can change that weak spot into a weather-resistant, code-compliant entry that works year after year, no matter the weather.

We use the same care we apply for basement suite upgrades in Vancouver. We install heavy-duty weatherstripping, a secure threshold, and a solid exterior frame. This creates a tight seal that stops air and water, plus an entry that looks great from the outside.

Why Port Moody Needs Upgrades

In Port Moody, steady fall rains and winter damp make a poorly sealed suite entrance a big problem. Moisture seeps into gaps around the door frame. This leads to rot, mildew, and drafts that make the whole building less efficient.

That’s why Port Moody homeowners need an exterior solution made for this climate. With heavy annual rainfall and closeness to the inlet, our exterior door upgrades use corrosion-resistant hardware and advanced seals to keep water where it belongs—outside.

Moisture-Resistant Door Installation

Port Moody’s high rainfall needs a door that won’t rot. We install fiberglass or steel doors with a composite frame. These materials resist moisture, unlike wood, which swells and decays in our damp climate. The adjustable sill has a backdam and a raised threshold to block rainwater from blowing under the door. Soft compression bulb seals at the bottom of the door press against the sill to form a gasket. Magnetic strips on the jambs lock in place to stop drafts.

Before installation, we layer the rough opening with a flexible flashing membrane. This membrane is shingled to direct any water outward onto the foundation drainage plane. We anchor the frame into the concrete with stainless steel fasteners and fill the shim space with low-expansion foam. This foam insulates and seals without pushing the frame out of square. Outside, a heavy-gauge aluminum drip cap with soldered end dams diverts runoff away from the door.

Structural Integrity and Moisture Control

The basement suite entrance breaks the building envelope at the most moisture-prone area: the base of the wall where soil moisture meets rain. In Port Moody, a continuous air barrier stops wet outdoor air from entering the wall assembly when the home depressurizes. The self-adhered membrane under the door connects to the home’s weather-resistant barrier above and the foundation waterproofing below. This creates a clear drainage path. Any water that gets past the door is directed to the outside through the sloped sill and pan flashing, instead of soaking the subfloor or framing.

Proper fastening is important for long-term performance. The door frame is secured into the concrete foundation deeper than typical wood framing. This helps resist wet/dry expansion and wind gusts from Burrard Inlet. The sill is set in a continuous bead of sealant and mechanically fastened. This ensures the threshold doesn’t shift and break the air seal over time. This layered approach—drain, air-seal, secure—keeps the basement suite entrance watertight year-round, even during snowmelt or heavy rain.

Port Moody Secondary Suite Rules

Port Moody’s Zoning Bylaw allows secondary suites, including basement suites, in single detached homes and duplexes. The suite must be a self-contained unit with its own entrance. It must also remain part of a single property and stay under 90 m² and 40% of the home’s habitable floor area. Your exterior door and window upgrades must follow these size and layout rules to keep the suite legal.

Under Port Moody’s Secondary Suites policy, you must register the suite with the City and get a business licence. You will also need to pay annual utility charges. If the suite existed before 2005, it may qualify for relaxed building code verification. However, the size and configuration limits still apply. Make sure your exterior entrance design fits these requirements before starting work.

The Standards of Maintenance Bylaw requires basement floors to stay dry and free of major cracks. Floor drains must be in good working order. When we install a new exterior door or improve drainage around the suite entrance, we ensure the finished space meets these safety standards for a dry, safe rental unit.
