What to know about recessed lights before insulating
Before insulation goes in above a ceiling, check what kind of recessed lights are there. Older recessed cans that are not rated for insulation contact were never meant to be covered, and an insulation crew may not know which ones need clearance.
A covered fixture that is not rated for it can overheat, shut itself off, burn through bulbs or warm the ceiling around it. Ask the installer to check the rating of every fixture before anything is covered. Many newer LED wafer lights are rated for contact, which avoids the problem.
Questions to ask before you sign
Questions for this job.
- Which areas are you insulating, and what R-value or depth will each area reach?A target for each area lets you compare bids side by side and check the finished work.
- Will you air seal the attic floor and the hatch before adding insulation, and which openings does that cover?Air moves through gaps around lights, pipes, and wiring. Those gaps are easiest to seal before new material covers them.
- How will you keep the soffit vents open, and are baffles included?Blown material can fill the path that lets outside air into the attic. Baffles hold that path open.
- Is the existing insulation staying, getting topped up, or coming out, and is removal priced?Pulling out old or damaged material is its own job, with its own cleanup.
- How will you handle old wiring, recessed lights, chimneys, and flues in the attic?Some wiring and fixtures need a check or clearance before they get covered. Once they are buried, nobody looks again.
- Where do the bath and kitchen fans vent, and will you run them outdoors if they end in the attic?A fan that empties into the attic puts moist air under the roof, and new insulation hides the problem.
- Will you leave depth markers, a written record of what was installed, and any rebate paperwork?Markers and a record let you confirm the coverage after the crew leaves. Utility programs may ask for them too.

Questions people ask
How much does insulation cost?
Nationally, the middle half of homeowners paid $1,430 to $4,940 for professional insulation work, and the typical job came in at $2,860. The area covered, the material, how much old insulation comes out and any air sealing can all move a quote. Use the checker with your ZIP for the range in your region.
Where do the insulation numbers come from?
From the Census American Housing Survey, where homeowners report work done on their homes and what they paid. We keep professional jobs, adjust each one to today's dollars, and weight them as the Census Bureau does. The survey asks about insulation added or replaced anywhere in the house, so the range covers attics, walls and other spaces together.
Why does this page not split attic and wall insulation?
The survey records insulation as one kind of job and does not say where it went. Splitting it would mean guessing, so we show one range and say so. If your quote is for one area, compare the scope with a second bid for the same area rather than reading too much into where it sits in the range.
What should an insulation quote include?
The areas covered, the material and the depth or rating it reaches, removal of old insulation if any, air sealing, ventilation baffles where needed, and protection of recessed lights and wiring where your code requires it. Ask how they will show you the finished depth. Get the scope in writing.
