Questions
Why are my new windows showing condensation?
Modern energy-efficient windows prevent humidity escape, making condensation more visible. This indicates proper sealing rather than window issues.
Do you offer military and senior discounts?
Yes, we provide special pricing for active military, veterans, and senior citizens on all home improvement services.
What financing options are available?
We offer 0% interest financing for qualified buyers, including up to 100% coverage of project costs.
How long does installation take?
Window projects finish in 1-2 days, roofing in 1 day, and siding in 2-3 days with complete post-job cleanup.
What area do you serve?
We operate throughout Northwest Indiana, including Porter, Laporte, Lake, Starke, Jasper, and Newton counties.
