After inspecting and identifying where air is leaking into or out of the home. Our technicians can help close up those leaks.
Inside the home, our technicians use expanding foam, caulk, and weather stripping to reduce or eliminate air leaks identified during the inspection. Expanding foam helps seal the large gaps between your plumbing, electrical boxes or drywall. Caulk and weather stripping help seal leaks around doors and windows.
In the attic, expanding foam helps seal around the penetrations in the walls for plumbing pipes or electrical wiring. Ceiling lights are one of the worst sources of air leakage into your attic. Areas above ceiling lights can be sealed and insulated effectively with boxes made from fireproof rock wool.
If the inspection reveals that the duct system has minor leaks, our technicians can seal the joints at the ducts and registers with mastic and caulk to minimize leakage. If we see extensive leaks, we recommend that a HVAC company come to fix them, preferably after we vacuum and before we add insulation in the attic. If we notice lots of bad wires, we recommend that an electrician come to fix them, preferably after we vacuum and before we add insulation in the attic.
