Full Home Remodeling in San Pedro
San Pedro whole-house remodeling that starts at the range hood: fan size, make-up air, duct caps built for damp coastal air, then every other room.
"Will a stronger range hood pull damp outside air into the house?" comes up on the first walk through a San Pedro kitchen. It can, if nothing replaces the air the fan pushes out. Past a certain fan size the code calls for a make-up air path, often a ducted inlet with a damper that opens when the hood runs, and placing it is part of laying out the kitchen.
Sizing the hood and its air supply
A hood is sized to the cooktop under it and the cooking done there, and its duct is sized to the fan. When the fan moves enough air to need make-up air, the supply is ducted from outside, filtered, and tied to the hood so both run together. In a tight house a strong hood running alone can also pull exhaust back down a water heater or furnace flue, which is why we check those appliances before choosing a fan. The make-up air inlet goes where the incoming air will not blow across the burners.
Damp air at the duct ends
Wherever the hood duct and the make-up air inlet leave the house, the caps take the weather. In a coastal setting we specify stainless or coated aluminum caps with a back-draft damper, set into a flashed opening, and a duct run kept short and nearly straight. Fasteners at the cap are stainless. Inside, the duct is sealed with foil tape and insulated where it passes through an unheated attic, so damp air that does get in does not condense on the cold metal and drip back toward the hood.
Full Home Remodeling in San Pedro: questions to settle first
Demolition and framing go first. The hood duct and make-up air path are framed in with the other rough work, which covers plumbing, gas, wiring and ducts, and all of it is inspected while open. Insulation and drywall follow. Cabinets, the hood itself, counters, floors and paint finish the house.
Yes, when the drawings show what carries the load. Taking out a bearing wall means a header beam and support posts specified by an engineer, and the set goes to LADBS, since San Pedro lies within the City of Los Angeles. A partition can come down once the pipes, wires or a hood duct inside it are moved.
Choose the cooktop or range and its hood together, since the fan size decides whether make-up air is needed. Settle the kitchen layout, appliances and any moving walls, then window and door sizes. Tile, paint and cabinet hardware can be picked once the drywall is up.
