Common service questions

How long does a kitchen remodel take?
Twin Cities kitchen remodel timelines: 8-12 weeks for a cosmetic refresh (paint, cabinet refinishing, new appliances, lighting), 10-14 weeks for a mid-range remodel (semi-custom cabinets, quartz counters, new tile, no structural changes), and 14-20 weeks for a full custom or structural remodel (wall removal, layout change, premium finishes). Anna captures scope at intake so we set realistic expectations from day one.
Are you licensed in Minnesota?
Yes. Cornerstone holds Minnesota Residential Building Contractor License #BC742381 issued by MN Department of Labor and Industry. Required for any residential remodeling project over $15,000 in Minnesota. We are also EPA Lead-Safe Certified (Firm #NAT-F093417), NAHB member, NARI member, and bonded + insured ($2M GL / $4M aggregate). Certificate of insurance available on request.
What is design-build and how does it differ from hiring an architect separately?
In a design-build relationship, a single contractor (us) handles both design and construction under one contract — designer, project manager, and trades all work for the same firm. In design-bid-build, you hire an architect separately, then put the design out to bid with general contractors. Design-build is faster, has fewer hand-off issues, and produces a single point of accountability. Most residential kitchen/bath/addition remodels are best served by design-build.
How much does a bathroom remodel cost?
Twin Cities pricing varies by scope: powder room refresh $10,000-$18,000; secondary bathroom remodel $20,000-$35,000; primary bathroom standard remodel $30,000-$55,000; primary bathroom with structural changes (wall push-out, layout reconfiguration, heated floor, wet-room shower) $55,000-$90,000. Anna captures scope and finish-level preference at intake so the consultation includes accurate budget direction.
Do you handle the permit and inspections?
Yes — every Cornerstone project includes permit procurement and inspection coordination through Minneapolis, St. Paul, or the relevant suburban building authority. We coordinate framing, electrical, plumbing, mechanical, insulation, and final inspections in sequence. All documentation provided at project close-out for resale and insurance records.
How does Anna handle insurance restoration calls?
For storm damage, water intrusion, or post-fire restoration calls, Anna routes to our dedicated insurance lane. She captures the carrier name, claim number, adjuster contact, and a brief scope description. Our restoration team coordinates with your adjuster, scopes the work to your policy, and executes with the same craftsmanship standard as our planned remodels. We also document supplements when the initial scope-of-loss misses damage.
