Frequently Asked Questions

General Contracting Services

What does a general contractor do?

A general contractor oversees your entire construction project—planning, permitting, coordinating trades, managing schedules and budgets, ensuring code compliance, and serving as your single point of contact from start to finish.

Why should we hire a general contractor?

Hiring a general contractor saves time and often saves money through our supplier relationships and efficient project management. We prevent costly mistakes, ensure professional results, and provide proper licensing and insurance coverage.

How do you select subcontractors?

We work with licensed, insured subcontractors who meet our quality standards. Our network includes electricians, plumbers, HVAC technicians, and specialty trades with proven track records.

Can you work with our architect or designer?

Yes, we collaborate with architects, designers, and engineers you’ve selected. We value good partnerships and provide construction input during design to ensure plans work within budget.

Project Management & Timeline

How do you keep projects on schedule?

We create detailed schedules with milestones, order materials early, coordinate subcontractor schedules efficiently, conduct regular progress meetings, and address issues proactively to prevent delays.

What happens if the project encounters delays?

We communicate immediately about timeline changes, explain reasons, and develop solutions to minimize impact. We adjust schedules and coordinate resources to get back on track.

How often will we communicate during the project?

Communication frequency depends on your preference and project phase. We typically provide weekly updates, but we’re always available by phone, email, or text.

Can we make changes during construction?

Yes, changes can be accommodated. We assess impact on budget and timeline, provide updated estimates, and document everything clearly through change orders before proceeding.

Permit processing varies by jurisdiction and project complexity. Simple permits take 2-4 weeks, complex projects can require 6-8 weeks or more. We submit complete applications to minimize delays.

What if permits are denied or need revisions?

We work quickly to address concerns and resubmit applications. Our experience with local building departments helps navigate the approval process efficiently.

Do you handle homeowner association approvals?

What inspections are required during construction?

Required inspections include foundation, framing, electrical, plumbing, mechanical, and final inspections. We schedule inspections, ensure work is ready, and address inspector comments promptly.
