Gas fireplace, stove, and insert installs are custom-quoted with precision gas line connections and high-performance venting. Every price is confirmed before work starts, with no surprise add-ons.
Sweep and inspection, $225 flat
Every sweep uses rotary equipment with HEPA containment, a full visual inspection, and a free chimney cap check, with floor-to-roofline protection and shoe covers so nothing reaches your floors. The price is confirmed before work starts.
Custom caps, made to fit
Caps from First Rate are locally made stainless steel, powder coated to fit your chimney exactly, and backed by a lifetime warranty. Pair one with a top-sealing damper, which pays for itself by keeping heated air in the house instead of letting it escape up the flue.
Gas fireplaces and inserts
Gas fireplace, stove, and insert installation comes with precision gas line connections and high-performance venting, custom-quoted to the space. Gas systems need less frequent sweeping than wood, but periodic checks keep venting and ignition safe.
Masonry and waterproofing
Tuckpointing, crowns, refacing, and full rebuilds from a crew with thirty years of brick and mortar experience. Leak diagnosis, step flashing, and breathable masonry sealant stand up to Oregon rain. All of it is custom-quoted before work begins.
