I would like to convey a story of a friend of mine, Kelvin Domineck Sr.
I met him when he became a cashier at the gas station that I visited for years, They have rewards points, anyways, he started there and we talked. I would arrive there full of saw dust on my clothes. He kept the place clean and I had to apologize for the trail that I had left behind. He didn't seem like the type of person that would settle for a cashier job, at least to me. He was a high school football coach on the South Side. "They won conference that year. They call me coach." He was a Chicago Public Schools security guard for many years. He is good with people.
He offered to help me with the new company GAPScoreGC in December 2024. I was teaching him to start a contractor business. We did work for friends and family. Each experience was a learning experience for him. He was getting the hang of it after 6 months.

We had plans to teach others from the community like I had taught him. The communities with low contractor populations and the need for quality service. We were to grow with the knowledge base of underprivileged communties.

And then at the end of July, I was going to make him an owner of GAPScore GC, Inc. and build a board of directors, he disappeared.
He was in Cook County Jail.
I can only believe that he was working at a private security firm for extra money in 2020. There was a terribly horrific incident while on duty. He had shot some one and hit another. It was in mistaken instance. He isn't violent or a danger. He was scared, made a mistake. The other people hurt filed charges.
He was arrested onsite and released on bail bond after 3 days. He didn't go to the sentencing hearing scheduled in 2020. They found him guilty of aggravated use of a fire arm and aggravated battery with a fire arm.
He made had been so afraid to go to jail, that he made another mistake. His shame made him keep it a secret from his family and friends.

Kelvin is to be released from Statesville Prison in July on good behavior.
We wish him God's speed.

GAPScore GC is closing it's doors this month, cancelling insurance and dissolving the corporation.
Thank you for your patronage.

When he gets out, I think we'll have to start a different kind of company to fit the communities needs.

We made a good living by following home addition builders. They built it a year ago.
We fix it for today.
This addition has a roof that goes over the exterior deck. That's a good green design attribute. However, how well you seal the open exterior of the original house and the new addition will tell if you know how to build for energy efficiency. This 18x12 single room addition has 6x framing, R-19 fiberglass bats, R-20 foam boards insulation on the interior of the crawl space foundation, and R-30 Attic insulation over the living space.
The occupants had to use an electric space heater and the home's original natural gas usage went up. The kitchen sink area became extremely cold.
That really shouldn't happen.

Don't wait to include us in your next project.

Everyone's getting older. Your house is too. Our age is the result of our actions in sustainability. The least sustainable room in the house, the bathroom. Water can slowly deteriorate everything. When we did this tile floor over 10 years ago, the sub floor of the original build had fallen out, the toilet was crooked and couldn't stay sealed, and water poured over the tub into the crawl space.
The original tile was laid on top of the 3/4" sub floor.
So, we replaced the damaged sub flooring, installed an additional 5/8" subfloor, a liquid membrane and 1/2" durarock virtually saving the floor joists framing beneath. The tile was purchased at a local vendor, but we only needed 3 big ones. The rest of the tile boarder and base are left overs from other jobs. We anticipated replacing the tub someday, so the tile design made it easy to remove the existing old tub and fiberglass overlay enclosure.
2 years ago, we replaced the tub with the shower basin, tile floor to ceiling, added upper/lower double shower heads, and installed an oak sliding door to the room.
Today, it has a 17-1/2" high toilet.
We're all getting older, might as well be comfortable too.

Before and after. This window hadn't been air sealed, was leaking when it rained, always had condensation, and it was thought it needed to be replaced. After air sealing around the window and repairing the caulk on the trim molding outside, it was still cold.
When the window air leakage was stopped, it only exemplified the thermal bridging and other sources of cold air.
So, we removed the drywall and insulation on the entire exterior wall. Use NAHB green building air sealing technique, we used 1" closed cell rigid foam board between each stud onto the sub wall sheeting and sprayed foam around it to air seal. Then, we re-installed the existing R-13 fiberglass insulation and reused the drywall, trim, and fixtures.

Before and after. Note the corner of the wall of this 2nd floor bedroom and the temperature change in the framing. There's R-39 insulation in the attic, R-13 in the walls, and insulation siding on the house. Yet, it could become more efficient and more comfortable with proper air sealing techniques.
Note in the after picture, the dark spot on the wall is colder than the rest because there's an exterior sconce light fixture and the electrical junction box is less R-rated insulated than the framing cavities.
A 20F degree change makes a huge difference.
"You should feel the difference."
