A contractor that only works on the outside of existing buildings.
Great Walli Construction is a Minneapolis company that repairs and replaces building envelopes: masonry, sealant joints, metal panel cladding, windows, storefront and the barriers behind them.
We work for owners, facility managers and property managers of offices, clinics, schools, churches, retail centers, light industrial and apartment buildings in the Twin Cities.
Why one specialty
Most leaks in Minnesota buildings start at transitions: where a window meets brick, where a wall meets the roof, where sealant has aged past its service life. Freeze-thaw cycles turn small gaps into spalled brick and wet insulation.
A general contractor sees these problems a few times a year. We see them every week. Focusing on the envelope lets us diagnose faster, price by the square foot and linear foot with confidence, and stand behind the warranty.

Flashing, barrier laps and lintel repairs disappear behind finished walls. We photograph them so you have a record for the life of the building.
