Attic air sealing in Pueblo CO - rooms that stop losing heat up through the ceiling

Most people call us because the upstairs is drafty, the room over the garage never matches the rest of the house, or the power bill keeps climbing even after somebody added insulation. That last one is the tell, since insulation over open gaps just has warm air blowing through it all winter. The price mostly follows how many openings your attic floor has and how much old insulation is lying on top of them, and the schedule turns on whether anything up there has to be fixed first. If the old stuff is soaked or full of droppings from a mouse that overstayed its welcome, insulation removal comes before sealing, because clean work on top of a mess keeps the mess. We look at your attic before we put a price on anything.

We start by pulling back the insulation along the attic floor so we can see the holes, since most of them have been buried for years. Then we seal around wires, pipes and the hatch, using sealant for small cracks, one-part foam for bigger gaps and rigid blocking, cut board fitted over the opening, where a hole is too big for either. Around furnace and water heater flues we use materials made for heat and keep wood and insulation back from the pipe. We check every can light before any insulation covers it, because some can't be buried and need a cover first. The hatch gets weatherstripping and a latch that pulls it snug. We leave the soffit and ridge vents alone because they're supposed to breathe, and we keep insulation from piling into the eaves for the same reason.

Sealing is usually half the job. Once the floor is tight, most attics need more on top, and in an older house that's retrofit insulation, adding to what's there without tearing anything apart. If your ductwork runs through the attic, I'll talk with you about spray foam insulation at the roofline instead, because foam seals and insulates in one go and puts the ducts on the warm side. Foam costs more, though, so for most houses I'd seal the gaps and top up with blown-in insulation, loose fill we blow in through a hose.

In Pueblo, building permits come from the Southern Colorado Building Department, and the department asks owners to check whether a permit is required before any work starts. Whether a sealing job on its own needs one isn't something I'll guess at. Pueblo County now handles building department questions in unincorporated areas, including Pueblo West and Colorado City, and the Colorado Springs side uses its own office. Before we start, we find out which office covers your address and whether your job needs a permit, and if it does, we pull it and line up the inspection. If you'd planned to pull it yourself, the department's posted guidance only allows homeowner permits on an owner-occupied single-family house, so a rental or a duplex doesn't qualify.

Most of the attics we open here belong to older houses that have been topped up a time or two, so the gaps sit under several layers and the can lights went in long before anyone thought about covers. Gas furnaces and water heaters with flues running up through the attic are common too. We find the same mix on jobs in Colorado Springs and do the work the same way there.
