Interior remodeling, refinished basements, ceilings, floors and drywall. Careful attention to detail leads to a great quality of work. A team you can trust to be there when they say they will, offering fair prices with astonishing quality.
"I reached out to Supreme Interiors and received a call within an hour and a in home consultation within 48 hours. While explaining what I was looking for, Justin offered suggestions on how to make it better. He provided a fair price and scheduled me quickly. On the day of my installation, Justin was on time and started working right away. I loved the final product but I realized that I explained something incorrectly to him so I asked to change the design after the work was complete. He was so gracious and understanding which was very kind considering the circumstances. I HIGHLY recommend Supreme Interiors. Justin and his team are very professional and provide great service. I’ve already hired him for another job."

I'm very diligent when it comes to doing the job proper. I won't walk away from something until I know it's completed correctly. I'm quick and there isn't much I cannot do.

"After getting about half a dozen quotes, we ultimately decided to go with Home Genius Exteriors. They were the most expensive of all the options, but we chose them because we knew exactly what we wanted, and they clearly understood our requirements. The process began with Lois, who was extremely helpful with all the initial paperwork. Then Alyssa took over and was consistently in touch with us—updating us on the schedule and rescheduling as needed due to weather delays. On install day, the crew showed up bright and early at 7 AM—just as promised. They got started right away. All materials and the dumpster had already been delivered days in advance, so there were no delays. They quickly set up tarps around the house and began removing the old shingles and boards—we opted for a full deck replacement. Joe, the project manager, stayed in contact via phone and text, letting me know he’d be arriving a bit later. That wasn’t an issue at all because his foreman, Ivan, had everything well under control. Once Joe arrived, we discussed a few things, and some minor adjustments were made based on my requests. The entire process was smooth—Joe was professional and made sure I was happy with everything. The crew finished around 4 PM, and then spent nearly 90 minutes on cleanup, making sure no nails were left behind—especially on the driveway. Overall, we're very happy with the service provided by Lois, Alyssa, Joe, and Ivan. We couldn’t be more satisfied with the experience. As for the quality and performance of the product, it’s still a bit early to judge, but so far, everything looks great. Thank you, Home Genius Exteriors!"

Insulation services FAQs
When choosing a professional insulation installer, consider asking these questions to determine the best fit.
Will you address air leaks in my house?
Can you provide an R-value (heat resistance) fact sheet?
What kind of insulation will work best for my home?
How do you handle signs of a water leak?
Are you licensed and insured?
Can you provide customer references?
The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.
If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.
In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:
High heating and cooling bills
Uncomfortable room temperatures
Ice dams on the edge of your roof
Roof leaks
Cold floors and walls
Freezing pipes
Temperature fluctuations
Visibly low insulation
Noise problems
Pest problems
On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:
Blown-in: $1–$4 per square foot
Spray foam: $2–$5 per square foot
Batt: $2–$4 per square foot
Structural insulated panels: $4–$7 per square foot
Loose-fill: $2–$5 per square foot
Reflective: $0.50–$1.50 per square foot
