From attic top‑ups to wall dense‑pack cellulose and continuous exterior mineral wool, effective insulation succeeds only when paired with disciplined air sealing. We use blower‑door testing to find leaks, choose safe sealants, and prioritize details around rim joists, hatches, and penetrations. Better R‑values mean little without airtightness, so we deliver both.
Cold‑climate heat pumps bring efficient heating and cooling to snowy regions, often replacing aging furnaces or providing hybrid backup. Paired with heat pump water heaters, smart thermostats, and zoning, they improve comfort while lowering emissions. We size systems precisely, consider electrical capacity, and plan load management to keep bills predictable.
Upgrading to triple‑pane units with warm‑edge spacers, insulated frames, and low‑e coatings tackles condensation and drafts at once. Proper flashing, back‑dam sealing, and continuous exterior insulation prevent thermal bridges. We align installation with air and water barriers so windows and doors strengthen the entire envelope, not just the opening.
Kitchens benefit from formaldehyde‑free cabinetry, durable quartz or recycled surfaces, and efficient ventilation. Bedrooms deserve quiet, low‑emission paints and natural flooring that survives pets and seasons. In basements, moisture‑tolerant insulation and mineral‑based boards prevent mold. We explain trade‑offs, maintenance, and realistic lifespans so decisions feel confident, not rushed.
Some homes leap to deep savings at once; others improve strategically over several seasons. We map dependencies, ensuring today’s window choice fits tomorrow’s exterior insulation and future solar. By ordering steps correctly, you avoid rework, preserve warranties, and protect rebate eligibility while keeping family routines relatively undisturbed.
Tighter buildings demand reliable fresh air. We design ventilation with heat recovery or energy recovery to maintain humidity, filter particulates, and supply steady oxygen without waste. Balanced ducts, quiet fans, and thoughtful placement protect sleep and concentrate fresh air where people live, study, relax, and recover daily.
A 1930s semi‑detached near the Danforth combined exterior mineral wool, air sealing, and triple‑pane windows with a cold‑climate heat pump. Winter drafts vanished, summer bedrooms cooled quietly, and yearly energy costs dropped significantly. The owners loved the calmer acoustics and said their toddler finally napped through afternoon traffic and heat.
An aging oil system was replaced with a high‑efficiency heat pump and weatherization focused on the attic and basement. Rebates covered a meaningful portion after documentation and advisor verification. The family noticed consistent warmth, cleaner air, and far fewer worries about fuel price swings and mid‑storm deliveries during winter.
Marine humidity and wildfire smoke challenged an older bungalow. We improved airtightness, added continuous exterior insulation, and installed balanced heat recovery ventilation. Indoor air now stays fresher during smoke events, windows fog less in winter, and the home holds stable temperatures with modest energy, even during shoulder seasons.
