My company is a blown cellulose insulation company with over 20 years of experience. I do all of my own work with no sub-contracting. Company owned and operated. Our services differs from other companies because unless we can save you money; we wouldn't do the work. My company completely covers all areas related to weatherizing your home. What that means is that we make sure to not only stop the air leakage throughout the home, but also make sure to that the areas of the home that need to breathe, breathes.

"Anthony and his crew did a great job insulating our home and sealing around the vents - he was prompt with both estimates and work, very competitively priced and straightforward about what we needed and what we didn’t need. For the work itself, he communicated very clearly leading up to it what to expect, showed up on time and finished the job in less time than promised, even with a very thorough clean-up. Looking forward to seeing lower energy bills in the coming months! Highly recommend Anthony Cunningham and InsulateKY.com for your insulation needs."

Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

"Extremely dissatisfied with my consultation! First off, booked an appt due to Toilet tank seal leaking and needing to be repaired/replaced. I book an appt for them to charge me $89 for them to tell me exactly what I told them was wrong in the first place. Second, the options presented to me where astronomical and absurd. I'm talking about a toilet repair mind you! $1375 for them to replace my toilet altogether. $591 to install a toilet that I purchase. Or 721 to rebuild the current toilet. I settled for paying $89 for those options I suppose so Free Estimate as advertised isn't correct! I'm an Army War Veteran and I refuse to be ripped off by companies like this one. I can buy a brand new toilet at Home Depot for $1-300 and install it myself in under an hour. Thanks for nothing and enjoy my $89!!!"

"perfect. guys were prompt, friendly, cleaned up after themselves. Very hard workers, explained to me what they were doing and worked one of the hottest weeks of the year in my attic so i could finally feel my air conditioning for the first time in over a year. Sleeping has been much more enjoyable since they installed better insulation, cant wait to see the difference in my first LGE bill. Would 100 percent recommend Mike and his crew for any attic repair work you need."

Insulation questions, answered by experts

In Louisville, schedule annual insulation inspections, especially after heavy rains or storms, to catch early signs of moisture or pest issues. Verify that vapor barriers remain intact and attic vents are unobstructed for optimal airflow. Clean gutters regularly to prevent water from seeping into walls. Use a hygrometer to monitor indoor humidity, and adjust dehumidifiers as needed to keep insulation dry and energy efficiency high.

Helpful?

In Louisville, the humid subtropical climate means insulation service projects must balance moisture control and energy efficiency year-round. Summers bring high humidity, so vapor barriers and effective attic ventilation are critical to prevent mold. Winters can be chilly, requiring insulation with a suitable R-value for both heating and cooling. After thunderstorms, check for water intrusion, as even small leaks can compromise insulation performance and indoor air quality.

Helpful?

In Louisville, homeowners often overlook air sealing before adding insulation, which can reduce energy efficiency. Skipping vapor barriers or blocking attic vents leads to trapped moisture and mold. Using the wrong insulation type for specific areas, or compressing materials, lowers performance. Failing to inspect for storm damage or ignoring R-value guidelines are also common errors. Missing out on local energy rebates is another avoidable mistake—plan carefully for best results.

Helpful?

For Louisville homes, blown-in cellulose or fiberglass batts with vapor barriers are effective in attics, while closed-cell spray foam excels in walls and crawl spaces for moisture resistance and air sealing. Rigid foam boards are ideal for basements, and crawl space encapsulation systems help manage humidity. Always use a 6-mil polyethylene vapor barrier and high-quality caulk to ensure proper air sealing and meet KY’s Climate Zone 4A R-value standards.

Helpful?

Homeowners in Louisville should check local building codes for insulation R-value requirements specific to Climate Zone 4A. Many older homes may need electrical upgrades before adding insulation. The Ohio River’s influence increases humidity, so moisture-resistant materials are a smart choice. Consider flood risks in certain neighborhoods and look for seasonal energy efficiency rebates. Scheduling projects in early spring or fall helps avoid peak humidity and weather disruptions.
