Frame material determines lifespan and costVinyl frames are the most popular in Salem — low maintenance, good insulation, $360–$760 per window installed. Fibreglass frames are stronger and more dimensionally stable at $665–$840 per window. Wood frames cost most and require painting maintenance but offer premium aesthetics. The right choice depends on your climate — in Salem, local climate conditions means moisture resistance is a key factor.
Glass package: double vs triple paneDouble-pane windows are standard in Salem and adequate for most applications. Triple-pane adds 10–15% to window cost and makes sense in rooms with extreme temperature differentials or noise issues. Low-E coatings (included in most mid-range windows) reduce heat transfer and UV — confirm Low-E is included in any quote, as some budget windows omit it.
Window count and installation complexityWindow replacement is priced per unit. A standard single-hung or double-hung window costs $300–$855 installed. Bay windows, bow windows, and oversized custom openings cost $1,140–$1,200+ each due to weight, framing, and flashing complexity. Confirm whether any of your windows fall into the custom category before accepting a whole-house quote.
Insert vs full-frame replacementAn insert replacement fits new windows into existing frames — lower cost but assumes the original frame is structurally sound. Full-frame replacement removes the entire window assembly including the frame — higher cost but allows for resizing and addresses rot or damage. In older Salem homes, full-frame replacement is often required once the existing frame is inspected. Ask which method is being quoted.
Energy rebates and tax credits reduce net costQualified energy-efficient windows (ENERGY STAR certified) are eligible for a federal tax credit of up to 30%, capped at $600 per year under current law. Many utility companies in Salem also offer rebates for window upgrades. Confirm that the windows being quoted carry ENERGY STAR certification and factor in the tax credit when comparing quotes.
Disposal and lead paint risk in older homesHomes in Salem built before 1978 may have lead paint on window frames. Federal law (EPA RRP Rule) requires certified contractors to follow lead-safe work practices during removal. Confirm your contractor holds EPA RRP certification if your home was built before 1978 — non-compliance exposes you to EPA fines and health risk. Old window disposal fees ($50–$150) should also be included in your quote.
