How much does it cost to remodel a house?
A whole-house remodel often costs $20,000 - $100,000+. Simple updates can run about $15 - $60 per square foot, while gut remodels, layout changes, kitchens, bathrooms, and structural work can push the project to $60 - $150+ per square foot.
The biggest quote mistake is comparing a cosmetic refresh to a true remodel. Demo, permits, project management, electrical, plumbing, HVAC, windows, flooring, cabinetry, fixtures, paint, cleanup, and contingency should be separated before you compare bids.

Before requesting whole-house remodel quotes
- Write down which rooms are cosmetic, which rooms are being remodeled, and which areas may need structural or system work.
- Separate must-do repairs from nice-to-have finishes so contractors are not pricing different projects.
- Ask whether design, engineering, permits, disposal, cleanup, and project management are included or billed separately.
- Take photos of each room, panel, plumbing fixtures, attic/crawlspace access, old damage, and any areas where walls or windows may change.
Unlock the hiring checklist
Use this before you call a general contractor, so you know what to ask and what to avoid.
Call a pro when…
- More than two trades need to be coordinated
- You are opening walls, moving layout, or changing structural elements
- Permits, inspections, or code upgrades are likely
- Kitchen or bathroom work is part of the remodel
- You need schedule control, change-order rules, and one accountable project lead
Repair or replace?
A phased cosmetic update works when the layout is functional and the home systems are in good shape. A deeper remodel makes more sense when several rooms are failing at once, old systems must be replaced, or piecemeal updates would be torn out later.
Need a cleaner scope before you call around?
Use the contractors checklist to compare the same work, questions, cleanup, and warranty before choosing a local company.
Related questions
What is the most expensive part of remodeling a house?
Kitchens, bathrooms, layout changes, structural work, plumbing, electrical, and custom finishes usually drive the highest costs. Hidden repairs can become the biggest line item after demolition.
Should I hire a general contractor for a whole-house remodel?
Usually yes if the project involves multiple trades, permits, inspections, sequencing, or change orders. A smaller cosmetic refresh can sometimes be handled with individual trade contractors.
How much contingency should I set aside?
For a larger remodel, many homeowners set aside 10% to 25%, especially when opening walls in an older home. The risk is higher when wiring, plumbing, rot, drainage, or structural conditions are unknown.
