Common Questions
As a Duluth homeowner, how do you handle common roofing problems like storm damage or skylight leaks?
We understand that Duluth's weather can be tough on roofs. For storm damage, we provide thorough inspections to assess wind impact on shingles, flashing, and structure, followed by durable repairs or full replacements using materials suited for our climate. For skylight leaks, we diagnose the issue—often failed seals or improper flashing—and perform precise repairs to restore a watertight seal, preventing interior water damage and mold. Our masonry and exterior wall expertise ensures any related brick or stonework is properly integrated and protected.
You offer so many services. Can you manage a larger project like a kitchen remodel plus a new patio?
Absolutely. Our evolution from a masonry specialist to a full-service contractor means we're uniquely equipped to handle complex, multi-phase projects. For a combined kitchen and patio project, our team coordinates the interior remodeling—including plumbing, electrical, and cabinetry—with the exterior masonry and concrete work for the patio. This integrated approach, managed under one roof, ensures seamless design, consistent communication, and a single point of accountability, making the process smoother for you.
What's your process for building or repairing a driveway or retaining wall in Duluth?
Given our freeze-thaw cycles, proper base preparation and drainage are critical. For driveways, we assess soil conditions, install a sufficient gravel base, and use durable concrete or paving techniques to prevent cracking. For retaining walls, we design for soil pressure and water runoff, using quality masonry or concrete blocks. For repairs, we diagnose the root cause—often water damage or shifting ground—before fixing the structure. We also offer sealing services to extend the life of both driveways and walls against Duluth's elements.
