What is not part of insulation (attic/crawlspace)
Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.
- Any job where labor and materials together reach $1,000 or more. A licensed contractor does work over that line, and the booking page says so.
- Roof repair, leak repair and sheathing replacement. See the roofing services for that.
- Mold remediation and animal removal. Those have their own services and must be handled before new insulation goes in.
- Asbestos-containing or vermiculite insulation. Material of that kind should be tested and handled by a licensed abatement contractor and not disturbed.
- Electrical work such as relocating wires, junction boxes or recessed light housings. That is a licensed electrician.
- Whole-house energy audits. See the home energy audit service for that.

Before you book insulation (attic/crawlspace)
Quick things that save a trip. Tick them off as you go; none of it is required to book.
Photograph what is in the attic
Take clear photos of the insulation, the joists and any wiring, and note where the hatch is. A pro can tell a lot from them, including whether old insulation can stay or must be removed.
Clear the path and the hatch
Move boxes and stored items away from the hatch and around the work area so the crew can reach every part of the attic. Items on the attic floor need to be lifted before insulation goes over them.
Fix leaks and moisture first
If you know of a roof leak, a damp crawlspace or a bath fan that vents into the attic, say so and have it handled before new insulation. Covering a leak does not stop it.
Ask for the R-value in writing
Ask the pro to state the type, thickness and R-value they will install, and to photograph the depth markers afterward. This makes it easy to confirm the work matches the plan.
Check for old wiring and recessed lights
Tell the pro if you know of older cloth-covered wiring or recessed lights, since these need different handling and clearance. A licensed electrician should evaluate suspect wiring first.
Plan for the weather
Attic work is easiest in mild weather. Ask the pro about scheduling in extreme heat or cold, and remember each pro lists their own workmanship warranty on their profile.
