Is it worth adding insulation to an older house in Bel Air South?
Retrofit insulation adds insulation to a house that's already built and lived in, usually loose fill blown onto the attic floor or into the walls. For most older homes in Bel Air South it's worth doing, as long as leaks, old wiring and old fill get sorted out first.
Most calls start with an upstairs that's too hot, a room over the garage that never warms up, or a power bill that keeps creeping. In an older house the attic usually has a few inches of tired fill, the walls may have nothing in them at all, and air slips through gaps around lights, pipes and the hatch, so the first thing I do is figure out where your heat is actually going. Sometimes the answer starts with attic air sealing, which means closing those gaps before any insulation goes in.
The price moves with how much is already up there and whether it can stay, how old the house is, whether we find old wiring or old fill that has to be dealt with first, and whether we're doing the attic, the walls or both. The schedule turns on the same things, plus any repair, permit check or licensed electrician that has to come before we insulate. Your written estimate gives you the figure for your house and the order I'd do the work in.
- Most retrofit jobs are the attic, the walls or both, and we pick that with you.
- We plan air sealing with the insulation, because the attic is open and the gaps are right there.
- Wiring, plumbing or heating work that turns up goes to a licensed trade we bring in.

(410) 836-5406Questions people ask about retrofit insulation
These are the questions I hear most from Bel Air South homeowners thinking about insulating an older house. If yours isn't here, ask me when I come out.
How much does attic insulation cost in the Baltimore area?
Installing attic insulation in the Baltimore area usually runs about $1,800 to $2,600 per job. That's what attic work typically goes for in the market, not a quote from us, and walls or a whole-house job get priced on their own once I've seen them. Whatever we do, it's satisfaction guaranteed on every job.
How do I get insulation into my walls without tearing them open?
The usual way is drill and fill, which blows insulation into each wall cavity through small holes near the top, from inside or outside. Drilling from outside breaks the layer behind the siding that keeps water out, so it has to be patched carefully, which is why re-siding is the ideal time for it. From inside that layer isn't touched, and the holes get plugged, patched with joint compound, sanded and painted. You can also ask whether the crew checks the filled walls with an infrared camera, a heat-sensing camera, before patching, since it shows any cavity that didn't fill.
How much can adding insulation save on my energy bill?
Federal energy figures say adding insulation to attics, floors and crawl spaces and sealing air leaks can save up to 15% on heating and cooling costs, on average. Up to is the key phrase, and if the numbers don't add up for your house, I'll tell you.
Who is allowed to do insulation work in Maryland?
Insulation is on the Maryland Home Improvement Commission's list of work that usually has to be done by a contractor the commission licenses. In houses built before 1978, anyone whose work disturbs lead-based paint also needs EPA certification and has to follow lead-safe practices, so it's fair to ask for proof. We're licensed and fully insured.
Do we have to leave the house while you add insulation?
Usually not for loose fill in the attic or walls, though it's dusty and noisy near wherever we're working. With spray foam, everyone stays out until the re-entry time, the point the foam maker says it's safe to come back with kids and pets, and I'll give you that before the day comes.
What causes hot upstairs rooms in an older house?
Usually it's thin attic insulation plus air leaking through gaps around ceiling lights, pipes and the attic hatch. Buried eave vents make it worse, because the attic can't breathe, so heat and moisture sit up there and new insulation ends up fighting them.
