Bedroom additions, primary suite additions, second-story additions, and full whole-home renovations. Architectural drawings, structural engineering, and permitting included.

The Twin Cities four-season climate drives a clear remodeling calendar. Knowing when to plan keeps project costs predictable and timelines on schedule.
Why answering every call matters more in this trade than almost any other.
The US residential remodeling industry generates $110B across 72,000+ businesses — and demand is structurally strong: aging housing stock, rising home equity, and elevated mortgage rates keeping homeowners in place and renovating instead of moving.

70% of homeowners contact only 1-3 contractors for a remodel — and live-answer first contact converts to consultation at 5x the rate of voicemail callbacks. The contractor who responds within the first hour wins the project at a disproportionately high rate.

VantaWeb-built design-build sites report a 94% reduction in missed inbound calls within 30 days — consultation bookings up 38% in the first quarter, with the lead-time advantage compounding into more signed contracts.

Design-build referral chains are the business model that compounds. VantaWeb is built to convert first-time inquiries into multi-project relationships.
A homeowner getting serious about a $80K kitchen remodel calls 2-3 contractors and signs with the one who answers first. Anna picks up every call, captures project scope and timeline, and books the design consultation directly into your calendar — typically within 24-48 hours of inquiry. Live-answer conversion runs 5x voicemail.
Anna asks the budget range (under $50K / $50-100K / $100-200K / $200K+), the scope (cosmetic vs structural), and the timeline driver (no deadline vs hard deadline like baby due, aging parent moving in, holiday hosting). Your estimator arrives with a complete pre-qualification record — not a blank intake form.
Many Twin Cities neighborhoods (Edina, St. Louis Park, Golden Valley, Linden Hills) have homes built before 1978 — EPA Renovation Repair and Painting (RRP) rules require certified work practices. Anna flags every pre-1978 caller for RRP-certified crew assignment and captures home build year as the first qualifying question.
Peak demand by month — so you know when to plan, design, permit, and execute for the right project type.

Cornerstone is an EPA-Certified Lead-Safe Firm (NAT-F093417). Federal RRP rules require lead-safe work practices for any renovation disturbing more than 6 sq ft of paint in pre-1978 homes.

Every project pulls the required permit (kitchen, bathroom, addition, basement finish, deck) through Minneapolis, St. Paul, or suburban building authorities. We coordinate every inspection — framing, electrical, plumbing, mechanical, insulation, final — and provide all documentation for resale and insurance records.
Remodels are project-priced per scope. Every project starts with a free in-home design consultation. The design + estimate package (3D rendering, material board, line-item estimate) is included with the consultation — no upfront design fees.
Six steps from your first call to a protected home — with documentation at every stage so you know exactly what was done.
Anna answers 24/7 — captures scope (kitchen / bath / addition / whole-home), budget range, timeline driver, and home age (RRP flag). Books the in-home design consultation directly into your calendar, typically 1-2 weeks out.
Designer and estimator meet you at the home to walk the space, understand your aesthetic and functional goals, photograph existing conditions, and discuss budget. Initial concept sketches and material direction emerge during the visit.
3D rendering, material board, and line-item written estimate within 2-3 weeks. Multiple scope options presented (cosmetic refresh vs structural remodel vs full gut) so you can choose the right project for your priorities and budget.
Permit pulled through the appropriate building authority. Construction starts on the agreed date. Project manager coordinates licensed sub-trades (electrical, plumbing, HVAC) and provides weekly progress updates with photos.
Inspections (framing, electrical, plumbing, mechanical, insulation, final) coordinated and passed in sequence. Finishes — cabinets, countertops, tile, fixtures, paint — installed to the design plan. Daily progress photos uploaded to your project record.
Punch-list walkthrough with you to mark any touch-ups. 2-year craftsmanship warranty on labor; manufacturer warranties registered on cabinets, appliances, fixtures, and structural materials. Final documentation packet delivered for resale and insurance records.
Every Cornerstone project is run by MN RBC-licensed staff with EPA Lead-Safe certification. No unvetted subs, no seasonal temps.
Real homeowners, real neighborhoods, real remodels delivered on time.
"Cornerstone redesigned our 1962 Edina kitchen — removed a load-bearing wall, opened the space into the dining room, installed semi-custom cabinets, quartz counters, and a 36-inch Wolf range. Started in October, finished before Thanksgiving as promised. Best decision we ever made on this house."
"Primary bathroom remodel in our St. Louis Park 1950s rambler — replaced the cramped 3-piece bath with a wet-room shower, heated floor, double vanity, and a private water closet. Cornerstone's designer convinced us to push out one wall by 18 inches and it transformed the space."
"Added a 480 sq ft primary suite addition over our attached garage in Minnetonka. Cornerstone handled architectural drawings, structural engineering, permitting through the city, all the trades, and we moved in 5 months from groundbreak. Beautiful work."
"Whole-home remodel after we bought a 1953 Wayzata rambler — kitchen, three bathrooms, new windows throughout, hardwood floors, painted exterior. Took 9 months but Cornerstone delivered every milestone on schedule. The 2-year craftsmanship warranty has not had a single callback."
"Finished our basement in Plymouth — family room, home office, guest bedroom, full bathroom, and storage. Egress window cut through the foundation, full mechanical relocation, the works. Cornerstone's crew kept the upstairs clean every day for 12 weeks. Best ROI of any project we have done."
"Our 1928 Edina home needed a top-to-bottom kitchen restoration — period-appropriate cabinetry, brass hardware, marble counters, restored hardwood. Cornerstone's designer respected the home's character and the result feels like it has always been there. Cabinet warranty plus their 2-year labor warranty is reassuring."
