"A sole proprietor business, Green Star provided a very competitive itemized written bid. Stuart was very accommodating in considering old (>100 years) home challenges and discussing insulation options and solutions. Promptly arrived on scheduled date, his team was diligent in adding blow in insulation to attic and exterior wall space, as well as foam to basement sill plates, all in one day. Very friendly, knowledgable, professional and unobtrusive in providing their services."

"My family owns several large metal buildings used to store some pretty expensive farm and ranching equipment. The extreme temperatures and harsh Kansas weather were both starting to take a toll on the machinery and other contents of the buildings, so we decided it'd be in our best interest to see what insulating the buildings would cost.
A friend of mine had told me about Airtight of Kansas out of El Dorado, so I gave them a call. Chris Garrison, the owner of Airtight, came on-site to inspect our building himself. He was extremely knowledgeable and reviewed our options very thoroughly, explaining that closed cell foam insulation was what he recommended for our building. He was able to schedule the job a couple of weeks after the initial inspection. The crew showed up on time and completed the job within the time-frame that we were given and conducted themselves in a very professional and courteous manner. There was no mess left behind, nor was our building, property, or any of the building contents damaged during the process, which was a huge relief!
W e have been more than satisfied with the results. We will definitely be giving Chris a call in the future to come back and insulate our other buildings on the property, and we would highly recommend Airtight to anyone needing commercial or residential insulation.

"Did the insulation in my attic. Fast and easy, very personable and flexible. Would recommend to anyone"
Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.
R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.
Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.
You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.
Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
