Royal Craft installs attic insulation and corrects attic ventilation problems for Downers Grove homes. Older DG housing was rarely built with the ventilation and insulation modern energy code requires. That is why so many Downers Grove homes lose expensive conditioned air through the attic in every season. Mauricio brings a specialty in attic conditioning, ventilation, and the interaction between the two that most contractors overlook.
Blown-in and batt insulation installation for Downers Grove attics. We insulate to modern R-value targets and address any ventilation problem the attic has at the same time. Insulation alone will not fix a hot or moisture-trapped attic.
Attic insulation and ventilation done together deliver real energy savings and consistent room-to-room temperatures. Downers Grove homeowners often see reduced heating and cooling costs after we correct undervented, underinsulated attics. Every job is scoped to your home’s specific attic geometry.
Living in Downers Grove means dealing with cold winters and humid summers. Without proper attic insulation and ventilation, your home loses expensive conditioned air through the attic in every season. That means higher heating and cooling bills, hot upstairs rooms in summer, ice dams in winter, and a roof that fails years before it should.

Ventilation is what makes attic insulation work. When you don’t address ventilation, the roof and the insulation both fail. We check ventilation on every attic project because attic conditioning is one of the parts of the trade most contractors get wrong.
Clear scope, pricing, and timeline upfront.
Skilled work done efficiently and on schedule.
We check everything to make sure it’s done right.
Downers Grove’s older housing stock has an attic problem. Mid-century ranches in Shady Lane Estates and Downers Grove Gardens, Victorian homes in Denburn Woods and Prince Pond, and even newer subdivisions like Fairview Pointe often have inadequate attic ventilation and insulation.
The result is trapped heat, ice dams in winter, high energy bills, and a roof that fails years before it should. We solve it. Call (630) 725-1000 for a free attic inspection.
Royal Craft was started in 1973 by Bill Cantalupo, who moved the shop to Downers Grove in the early 1980s. But the attic and ventilation specialty really came with Mauricio, who joined Bill as partner in 2023. Mauricio came from a big commercial roofing company and had spent years learning what most residential contractors miss: an airtight roof over an undervented attic causes more damage than a leaky roof over a properly conditioned one.
That expertise is what makes attic insulation different at Royal Craft. We are family-run, over 50 years in the trade, and complaint-free with the BBB since 2010. Bill or Mauricio is on every insulation job.
When you have been burned by a bad contractor before, these are the questions you learn to ask. Our answer is yes to all five:
After we finish an attic project, homeowners usually notice two things right away: the upstairs rooms feel different, and the crew left the space cleaner than they found it. One review says it best:
“It was a pleasure working with you guys. You really know what you’re doing and kept us informed the whole way. You made it super easy for us to understand everything.”
