How to Use the New Home Bake-Out Cost Calculator
New construction and freshly renovated homes can off-gas formaldehyde and other volatile organic compounds (VOCs) from paint, flooring, and cabinetry, triggering "new home" symptoms like headaches and eye irritation — which is why a bake-out and air quality improvement plan is common before moving in. This calculator takes your home size, bake-out method (DIY or professional), and air purifier rental months to show the combined estimated total.
A DIY bake-out raises indoor temperature to around 85-105°F using your own heating system, then vents the home after a few hours, repeating the cycle over several days at low cost but with limited effect. A professional bake-out service uses commercial equipment to reach higher temperatures and circulate air more effectively, clearing VOCs faster at a higher price — and adding a short-term air purifier rental during the first weeks of move-in can noticeably improve how the air feels.
Actual results and cost vary with the materials used, timing relative to construction, and season (VOC off-gassing speeds up in warmer temperatures), so treat this figure as a planning estimate. If symptoms are severe, pairing this with a professional indoor air quality test is also worth considering. The FAQ below explains how bake-out works and how the two methods compare.
Frequently Asked Questions
New building materials and furniture off-gas VOCs like formaldehyde. Raising indoor temperature speeds up that off-gassing, and then ventilating clears it out — commonly done before moving into new construction.
DIY repeats heating and ventilating cycles at low cost but with limited effect. A professional service uses commercial equipment to reach higher temperatures and circulate air, costing more but clearing VOCs faster.
