Excelsior neighborhoods
Three distinct corridors, three distinct material mixes — Downtown Victorian, Stubbs Bay lake-corridor, Big Island cottage-conversion.
Late-1800s Victorian historic homes. Period-correct siding, half-round copper gutters, restoration-grade detailing. CertainTeed Presidential Shake TL and cedar shake are the typical roof picks.
Lake Minnetonka shoreline properties — higher-spec ice-and-water shield extension and better-rated underlayment. Lake-shoreline overlay paperwork handled for lake-facing properties.
Former summer cottages converted to year-round residences. Whole-envelope assessments — framing, ventilation, insulation upgrades to address root causes, not just symptoms.
















Excelsior housing stock
Excelsior's housing stock is small but distinct. Downtown holds late-1800s Victorian historic homes. The streets along the lake hold former summer cottages converted to year-round residences. Newer custom builds on the Big Island side and Stubbs Bay add the lake-corridor premium tier.
Cottage-to-home conversions + Victorian restoration
Cottage-to-home conversions along the lake have unique exterior challenges — framing, ventilation, and insulation often inadequate for year-round use. Lake-adjacent homes experience more wind, more moisture cycling, more ice-dam pressure than inland homes. We default to higher-spec ice-and-water shield extension and better-rated underlayment on Excelsior installs.
City of Excelsior Building Department: 339 Third Street, Excelsior MN 55331, (952) 474-5233. Lake-shoreline overlay paperwork handled for lake-facing properties. We pull every Excelsior permit before crews start work.

Downtown Excelsior Victorian
Excelsior's late-1800s downtown Victorians call for period-correct materials and craftsmanship. James Hardie ColorPlus in painted profiles matching original Victorian proportions, half-round copper gutters, cedar shake or DaVinci synthetic slate for the roof. Crown molding, soffit trim, and fascia restoration on every install.

Services + Excelsior pricing
Roofing $20K–$80K. Siding $25K–$70K. Windows $18K–$60K. Gutters $1.5K–$5K. Victorian historic restoration and lake-cottage conversions are most of the Excelsior mix — both call for higher-spec installs than typical inland work.

Roofing
$20K–$35K standard (CertainTeed Landmark Pro on smaller cottages). $35K–$80K premium (Presidential Shake TL, cedar shake, DaVinci synthetic slate — we install, not Authorized).

Siding
$25K–$70K. James Hardie ColorPlus for Victorian restoration, LP SmartSide for cottage-to-home conversions, EDCO Steel on homeowner request for lake exposure.

Windows
$18K–$60K. Kolbe Heritage ($2,500–$6,000 per window) for Victorian restorations, ProVia Endure for cottage conversions, Pella Architect Series for newer custom builds.

Gutters + storm
$1.5K–$5K. Half-round copper available on architectural homes. Lake-moisture-rated gutter guards. Storm-claim work insurance-covered minus deductible.
2026 Excelsior pricing
Two scopes most Excelsior homeowners book. Lake-corridor customs and Victorian restorations carry higher per-square costs than inland work — premium materials + lake-exposure- rated installs are the norm here.
Lake-exposure-rated · Victorian + cottage + custom

Standard $20K–$35K (CertainTeed Landmark Pro)
Premium $35K–$80K (Presidential, cedar shake, DaVinci)

Why Excelsior
Three reasons Excelsior homeowners hire us: historic + lake-cottage experience, lake-exposure-rated installs, and a lifetime workmanship warranty on every residential install.

Historic + cottage
Excelsior's housing splits between Victorian historic and former-cottage conversions. Both need different materials and different installation approaches. We carry the certifications and the trade-detail experience for both — period-correct cedar shake, copper accents, envelope upgrades for year-round use.

Lake-exposure installs
Lake-adjacent homes experience more wind, more moisture cycling, and more ice-dam pressure than inland homes. We default to higher-spec ice-and-water shield extension and better-rated underlayment on Excelsior installs — inland-grade specs aren't enough for the shoreline.

Lifetime workmanship
Industry standard on roofing workmanship is 5 to 10 years. We back every Excelsior residential install for as long as you own the home. Joe walks every Excelsior install over $40,000 — most Big Island and Stubbs Bay customs clear that threshold.
