Matt (and his team) has been a SAINT throughout my homeowners insurance claim!! He was there to fight right beside me with any insurance issues, was quick to get started on repairs to prevent further damage, had prompt communication with me even outside of business hours, and even communicated directly with my mortgage company which he did not have to do. 100% will recommend to my customers, friends, and family for all of their repair/construction needs!

Tips & Guides

Advice From Our Gaf-certified Team

Choosing the Right Siding for Your Home

Siding affects both your home's curb appeal and its protection against Iowa's temperature swings and moisture. From wood-grain finishes to more durable engineered options, the right material depends on your maintenance preferences, budget, and the look you're going for.

  • Consider durability against wind, hail, and freeze-thaw cycles
  • Compare maintenance needs across materials
  • Match style and color to your home's architecture
  • Factor in long-term energy efficiency

Deck Maintenance Tips for Every Season

A well-maintained deck adds outdoor living space and value to your home, but Iowa's seasonal swings can take a toll on materials over time. Routine upkeep helps prevent warping, rot, and fading so your deck stays safe and looks great for years.

  • Clean debris from between boards regularly
  • Inspect for loose or warped boards each spring
  • Reseal or treat wood decking as needed
  • Check railings and stairs for stability

Planning a Whole Home Renovation: Where to Start

Renovation projects can feel overwhelming, especially when tackling multiple rooms or systems at once. Starting with a clear priority list and realistic budget helps keep the project on track and prevents scope creep.

  • Identify must-haves vs. nice-to-haves early
  • Set a realistic budget with a contingency buffer
  • Sequence work to minimize disruption to daily life
  • Get clear timelines before work begins
