High Performance Attic Insulation

We purchased a 1980s home and the attic insulation was original, compressed, and completely inadequate. High Performance Attic Insulation removed all the old contaminated material, air-sealed every single penetration around recessed lights and plumbing stacks, and installed R-49 blown-in cellulose with a radiant barrier overlay. The estimator was patient and walked us through every option without pressure. The crew was respectful, wore booties, and even helped move a few storage boxes we had up there. Our heating bill dropped significantly this winter and the house holds temperature beautifully. Worth every penny.

Our home was built in the 1960s and the attic insulation had settled significantly over the decades. High Performance Attic Insulation removed all the old contaminated material, air-sealed every ceiling penetration, and installed new eco-friendly blown-in insulation with a radiant barrier overlay. Our heating bill dropped noticeably and the house feels much tighter. The crew was efficient, respectful, and the cleanup was immaculate. Professional operation from start to finish.

I contacted High Performance Attic Insulation after struggling with our second-floor bedrooms that were always 10 degrees warmer than the rest of the house. Their estimator arrived on time, climbed into our tight attic space without hesitation, and used an infrared camera to show me exactly where the old insulation had settled and where air was leaking. He explained the science behind radiant barrier and cellulose without any technical jargon. The crew showed up at 7:30 sharp, worked steadily all morning, and had everything finished by early afternoon. They laid down runners, sealed the attic access with plastic, and vacuumed thoroughly. Our upstairs is finally comfortable and my AC cycles half as often. Truly professional from start to finish.

Outstanding results from true experts. We have a complex roof line with multiple valleys and low-clearance areas that other companies didn't want to tackle. High Performance Attic Insulation saw it as a challenge they were equipped for. Their crew worked patiently and skillfully to ensure every single cavity was properly air-sealed and insulated. The before-and-after difference in both temperature consistency and the reduced strain on our air conditioner is remarkable. They deliver on the promise of their name.

I am thoroughly impressed with the science-based approach. They explained how attic performance is a balance of air sealing, insulation R-value, and ventilation, and they optimized all three for our specific home. The crew was clean, respectful, and their workmanship is flawless. Our home is now quieter, more comfortable, and uses far less energy to heat and cool. This wasn't just an upgrade; it was a complete re-engineering of our home's thermal envelope. Exceptional service.

This company is in a league of its own. From the initial assessment, which included thermal imaging, it was clear they approach the attic as a critical system, not just an empty space to fill. Their proposal was detailed and technical, explaining exactly how each step would improve performance. The installation team executed the plan with precision. Our attic is now a tightly sealed, properly insulated thermal boundary. The comfort and efficiency gains are immediately noticeable and profound.

Choosing High Performance was the best investment in our home's efficiency. They transformed our underperforming attic into a key asset. The project manager kept us informed, and the field crew was a well-coordinated team of specialists. They used high-grade materials and techniques that clearly go beyond standard practice. The improvement is not subtle—our living space is perfectly comfortable year-round, and we have complete confidence in the longevity and performance of their work.

We hired High Performance Attic Insulation after our HVAC contractor said our system was struggling due to poor attic conditions. The difference their work made is astonishing. They didn't just add insulation; they performed a comprehensive air seal, installed a radiant barrier, and upgraded our ventilation to modern standards. The crew was incredibly professional and meticulous. Our home now reaches and maintains the desired temperature effortlessly, and our energy bills have dropped significantly. This is true high-performance work.

We had a fantastic experience. After suffering through sweltering summers with a second story that was always 10+ degrees hotter, this company provided the solution. Their performance package included dense-packed insulation in the knee walls, advanced air sealing at all penetrations, and properly sized attic fans. The crew was efficient, professional, and left the site spotless. The second story is now just as comfortable as the first. They solved a problem we thought was unsolvable.

From the first consultation to the final walkthrough, the level of professionalism was exceptional. The quote was transparent and valued engineering over simple square-footage pricing. The crew worked with a focus and expertise that was impressive to witness. They treated our attic like the critical building component it is. Our home's overall performance has been elevated to a level we didn't think was possible. For anyone serious about building science and peak efficiency, this is the only company to call.
