Frequently Asked Questions

Whole Home Renovation Process

How long does a whole home renovation take?

Most whole home renovations take 3-6 months depending on scope and home size. Historic homes or extensive structural work takes longer. We provide realistic timelines based on your specific project.

Can we live in the house during renovation?

It depends on scope. Some renovations allow you to stay with significant inconvenience. Extensive work often requires temporary relocation. We discuss living arrangements during planning.

How do you phase whole home renovations?

We complete work room by room or floor by floor when possible. This keeps parts of your home usable during construction. Phasing extends timelines but makes living through renovation more manageable.

What permits are needed?

Permits are required for structural changes, electrical work, plumbing modifications, and mechanical updates. We handle all permit applications and coordinate inspections throughout the project.

Historic & Specialty Renovations

How do you match materials in historic homes?

We source materials carefully, sometimes custom-order items, and use craftspeople who can replicate period details. Perfect matches aren’t always possible with discontinued materials, but we get close.

What's involved in fire damage restoration?

We remove damaged materials, treat smoke damage, address water issues from firefighting, rebuild structure to code, and restore finishes. Timeline depends on damage extent and insurance approval process.

Can you make homes wheelchair accessible?

Yes, we widen doorways to 36 inches minimum, build ramps or no-step entries, create roll-in showers, lower counters and switches, and reinforce walls for grab bars. Accessibility modifications improve safety.

Do Victorian features need special handling?

Victorian details like ornate trim, bay windows, and original woodwork require careful preservation. We protect these features during construction and restore them properly. Replacement pieces get custom-made when originals can’t be saved.

Structural & Systems

What structural changes are possible?

We can remove non-load-bearing walls easily. Load-bearing walls require engineering, beams, and proper support. We assess what’s structurally feasible and explain costs for different approaches.

How do you update old electrical systems?

Old homes often need panel upgrades, new circuits, proper grounding, and updated wiring. We replace knob-and-tube wiring, add outlets where needed, and bring everything to current code.

What about old plumbing?

We replace galvanized pipes with copper or PEX, update fixtures, improve water pressure, and ensure proper venting. Old plumbing often has issues that need addressing during renovation.

Can you improve energy efficiency?

Yes, we add insulation to walls and attics, upgrade to efficient windows, seal air leaks, install programmable thermostats, and upgrade to efficient HVAC systems. Energy improvements reduce utility costs significantly.

Budget & Timeline

How much does whole home renovation cost?

Costs vary widely based on home size, scope, and finishes. Historic work costs more due to specialty labor and materials. We provide detailed estimates after assessing your home and understanding your vision.

What causes delays in whole home renovations?

Hidden conditions like rot or structural issues, material availability, permit processing, and weather affect timelines. We plan for contingencies and communicate immediately when delays occur.

Should we renovate or rebuild?

This depends on structure condition, renovation costs versus new construction, historic value, and location. Sometimes starting over makes more sense financially. We help you evaluate both options honestly.

Do renovations add home value?

Whole home renovations typically return 50-70% of costs in immediate home value but improve livability and prevent deferred maintenance from becoming worse. Quality renovations make homes more sellable.

Quality & Completion

How do you protect belongings during renovation?

We seal off work areas, cover and protect furniture, use dust barriers, and store items safely. For whole home renovations, removing belongings before work starts usually works best.

What warranty comes with renovations?

We warranty our workmanship. Manufacturers cover materials, fixtures, and appliances. We address issues promptly during warranty periods and remain available after completion.

How do we maintain renovated homes?

Follow material care instructions, address minor issues promptly, maintain mechanical systems regularly, and keep up with routine maintenance. We provide guidance for materials used in your renovation.
