What we find in Hilmar houses

Hilmar is dairy country, and the houses we work on sit either out on the country roads or in the neighborhoods closer to town. Out on the farms we see older houses that have been added onto over the years, along with shops and outbuildings, while in town it's mostly newer homes. The calls sound a lot like the ones we get from Delhi and Turlock, with hot upstairs bedrooms, a drafty back room or cold floors over a crawl space.

That mix shapes the job. In the older houses the insulation is usually thin, settled or fouled by mice, so I look at what's up there before I talk about adding anything, and in the newer ones it's more often gaps at the hatch and the can lights that let the heat through.

Insulation work we do in Hilmar

Working in Hilmar under county rules

Hilmar isn't its own city, so building permits here come from Merced County's Building and Safety Division, which issues permits and inspects all construction in the county's unincorporated areas. I check whether your address falls under the county, and if the job needs a permit we take care of it and set up the inspection, so the schedule leaves room for that visit. Before you hire anyone, ask for two things. One is a state contractor license, covered in the questions below, and the other is a Merced County business license, which the county requires of every business working in its unincorporated areas.

As an insulation contractor based in Merced, CA, we work in many cities around it, north toward Modesto and south toward Madera, and Hilmar is a regular drive for our crew. Your price comes down to how big the attic or crawl space is, whether old insulation has to come out first, how many gaps need sealing, how easy it is to get in there, and whether foam or loose fill is the right call. The schedule turns on any removal, the permit if there is one, and whether you need to be out of the house for foam. I write down what I find, and the estimate I hand you has your own figure on it.

  • I go up with a flashlight and take photos before any quote, so you see the wet spots, droppings or thin edges yourself.
  • If the old insulation is soaked or fouled, it comes out before anything new goes in, because covering it keeps the smell and the damp.
  • We seal around can lights, pipes, wires and the hatch first, so the new insulation isn't working against a draft.
  • We keep the eave vents clear and carry the depth out to the edges, since a buried vent lets moisture build up in the framing.
  • If your ductwork runs through the attic, foam on the roofline can be worth the extra cost, and otherwise sealing and topping up loose fill usually wins.

Questions Hilmar homeowners ask about insulation

Do I need a permit to insulate my attic in Hilmar?

Some insulation jobs in Hilmar may need a county building permit, and we check yours before work starts. Merced County's permit guide calls for a permit on alterations, repairs and improvements as a rule of thumb, with many exceptions that mostly cover minor repairs, and it doesn't list insulation by name. Only the property owner or a licensed contractor can get a building permit in the county, with a few exceptions, so if yours needs one we take care of it and set up the inspection.

Does an insulation contractor need a California license?

Yes, for most insulation jobs, because the Contractors State License Board requires a license when the work costs $1,000 or more in labor and materials, even split across more than one contract. A license is also required when the job needs a building permit or uses any other workers. We're licensed and insured, and you can ask any contractor for their license before you sign.

Do we have to leave the house while insulation is installed?

For blown-in insulation and air sealing you can usually stay home, though we'll ask you to keep kids and pets away from the hatch while we work. Spray foam is different, so everyone, pets included, stays out until the foam's re-entry time is up and it's safe to come back in. We tell you that wait before the job is scheduled, so you can plan where to be.
