Adding insulation to an attic that does not meet current R-value recommendations, sealing the air bypasses that render existing insulation less effective, and ensuring the attic is correctly ventilated so moisture does not accumulate are the three steps that together make attic insulation work as intended. Our handyman specialists handle attic insulation installation, air sealing, and insulation level upgrades.
Professional Solutions
Attic insulation performance depends on two things: the R-value of the insulation installed, and the quality of the air sealing beneath it. Insulation slows heat transfer through the building material, but air leaks bypass the insulation entirely, and an attic with R-38 insulation over unaddressed air bypasses at the top plates, recessed lights, and plumbing and electrical penetrations will underperform significantly. Kaminskiy Care and Repair’s handyman specialists air-seal the attic floor before adding insulation, so the new R-value performs as the rating implies rather than as a theoretical number with real-world air leakage deducting from it. With crews across the United States, a properly insulated attic is a call away.
Blown-in insulation added over unaddressed air bypasses improves the insulation level on paper but underperforms in practice, the air movement through the bypasses carries heat past the insulation rather than through it. Our handyman specialists seal the bypasses before blowing in insulation.
Top plate gaps, electrical and plumbing penetrations, and recessed light cans are air-sealed before any new insulation is installed, so the R-value improvement performs as the rating suggests.
The target R-value for the installation is selected for the local climate zone, Energy Star and DOE recommendations vary by geography and we install to the correct target for the location.
Insulation is not installed over soffit vents, baffles are installed to maintain the ventilation channel from soffit to ridge, so moisture can move through the attic as designed.
We stand behind our attic insulation installation workmanship.
BEFORE
AFTERBlown-in cellulose and fiberglass insulation installed to the target depth for the climate zone R-value, with air sealing completed first and soffit baffle installation to protect ventilation channels.
Air sealing at the attic floor, top plate gaps, electrical and plumbing penetrations, attic hatch, and recessed light cans, before any insulation work, and as a standalone service for homes that have adequate insulation depth but poor air sealing.
Fiberglass and mineral wool batt insulation installed in attic knee walls, attic floor joist bays where blown-in is not appropriate, and around attic hatches, with correct vapor barrier orientation for the climate zone.
Air sealing first, then the right depth of insulation, with the vents kept clear.
Most attics leak air long before they run short of insulation. We seal the gaps around pipes, wires, can lights and the top plates, then bring the insulation up to the depth your climate calls for. The attic stays cooler in summer, the rooms below hold their heat in winter, and the HVAC runs less.

Insulation is rated by R-value, and R-value comes from depth. Many older homes have only a few inches, well under what current code asks for in your climate. We measure what you have and tell you how much to add.
Insulation slows heat. It does not stop air. Warm, moist house air leaking into the attic through gaps around pipes, lights and plates carries heat and moisture with it. Sealing those gaps first is what makes the insulation work.
Insulation pushed into the eaves blocks the soffit vents and traps moisture. Baffles hold a channel open so air moves from the soffits to the ridge. A dry attic is a healthy roof.
Insulation that is wet, moldy or full of rodent droppings should come out, not get covered. We remove it, clean the space and start fresh. Dry, clean insulation can stay and be topped up.

Call 202-931-5740It depends on your climate zone and what is already there. Most attics we see have a few inches of old insulation where current code calls for roughly a foot or more. We measure the depth in several spots, check the type, and tell you how much to add. The number is in your written estimate.
Blown-in insulation fills the whole attic floor evenly, including odd spaces and around wiring, and it is the usual choice for topping up an existing attic. Batts suit open joist bays, knee walls and rafters where you want the material to stay in place. Many attics get both.
If the old insulation is dry and clean, yes. New material goes right on top after we air seal. If it is wet, moldy, matted flat or contaminated by rodents, it comes out first. Covering a problem does not fix it.
For most homes with a thin or patchy layer, yes, and the upstairs rooms feel it first. How much depends on your climate, your system and how leaky the attic was. Sealing the air gaps makes the difference, which is why we do it before the insulation goes in.
The price depends on the size of the attic, the depth you add, the material, how much air sealing it needs and whether old insulation has to be removed first. A top-up on a clean attic is the simplest job. You get the price in writing before we start.
