“I’m finally getting my sewing room!” Wilmington, DE
“We contacted Mark Group because our third floor was virtually unusable. It was a sauna in the summer and an icebox in the winter. Mark Group sealed and insulated the attic above the third floor and knee walls on the third floor. Downstairs, they used spray foam to seal and insulate our basement and took almost a full day overhauling our crawl space. The improvements made a huge difference. We’re now finally in the process of finishing the third floor and I’m close to having my sewing room!”
Mark Group air seals and insulates homes to ENERGY STAR standards.

More than half of the energy consumed in the average Wilmington home is associated with heating and cooling. During a Wilmington Home Energy Assessment, a Mark Group Home Performance Advisor identifies exactly where your home is wasting energy and recommends prioritized upgrades that best meet your comfort concerns and budget.
We look for signs of unwanted air leakage that allows humidity to seep into your home in the summer and causes uncomfortable drafts in the winter. We also check that key locations in your Wilmington home, such as your attic, basement, crawl space, exterior walls and garage, are properly insulated.
Mark Group offers two options for a home energy analysis in Wilmington: Home Energy Assessments & Home Energy Audits.
