Florida Repair Cost Estimator: Roof, HVAC, Plumbing, Windows and More

Home › Tools › Repair Cost Estimator · Updated October 25, 2026

Most sellers who ask “should I fix it first?” are really asking a money question: how much will the work cost, and will it come back in the sale price? You cannot answer the second half without the first. Yet repair costs are hard to pin down before you call contractors, and in Florida — where roofs, windows and building systems are tied to wind codes, flood rules and insurance underwriting — the range between a quick patch and a code-compliant replacement can be wide.

This estimator gives you a structured starting point. It lists the repairs that most often come up when Florida homes are inspected, insured or prepared for sale, fills in low and high unit costs from published cost guides, and lets you change every number. The text below explains what drives each item, why Southwest Florida prices can land above or below national figures, which jobs need permits and licensed contractors, and how to turn the range into decisions.

Where the Default Numbers Come From

Every default in the estimator is a typical range published by a national cost guide, checked in October 2026. These guides compile homeowner-reported project costs and contractor pricing from across the United States. They are useful for orientation, not for budgeting a specific Florida house. Here is the source behind each line:

Two cautions apply to all of them. First, cost guides publish ranges that cover most projects, not all; each one notes outliers well above the high figure. Second, a national range blends regions with very different labor rates, codes and weather. A Southwest Florida roof built to resist hurricane-force wind, or a septic system that must sit above a high water table, can price well beyond a national midpoint. Treat the defaults as placeholders and replace them as soon as you have local numbers.

What Drives the Cost of Each Repair Item

For each line, here is what moves a bid up or down. For the underlying problems themselves — why insurers flag certain materials, how 4-point inspections work — see our page on selling a house that needs major repairs and the guide to old wiring and plumbing.

Roof replacement

Roofers price by the “square” (100 square feet of roof surface), and roof area is larger than your home’s living area once you add pitch, overhangs, garage and lanai roofs. Material is the biggest swing: architectural shingle sits at the low end, while concrete or clay tile and standing-seam metal sit at the high end. A hip roof with many valleys takes longer than a simple gable. Florida-specific items add cost: secondary water barriers, upgraded nailing and fastening schedules, roof-to-wall connections, and replacement of rotted decking discovered once the old roof is off. In this estimator, enter your roof area and adjust the per-square-foot figures for your material. Roof age also matters for insurance: Florida law (section 627.7011, Florida Statutes) bars insurers from refusing to issue or renew a homeowner’s policy solely because a roof is under 15 years old, and lets owners of older roofs get an inspection before an insurer can require replacement.

HVAC system

The default covers replacing a typical central system. Cost rises with tonnage, efficiency rating, a heat pump versus straight cooling, ductwork replacement, a relocated or elevated air handler, and electrical or drain-line corrections the installer must make to pass inspection. Homes with two systems should enter 2. In Southwest Florida, where air conditioning runs most of the year, outdoor units near saltwater can wear faster, and buyers’ inspectors pay close attention to age.

Water heater

A like-for-like tank swap is at the low end. Moving to a tankless unit, adding a drain pan and expansion tank to meet current code, or upgrading the electrical circuit pushes it higher. Water heaters are commonly called out on insurance 4-point inspections when they are old, so even an inexpensive item can affect insurability.

Electrical panel

The default is a panel replacement. A full service upgrade — say, from 100 to 200 amps — can require a new meter base, service conductors and coordination with the utility, and may land above the high figure. Panels from certain discontinued manufacturers are often flagged by Florida insurers, which is why this line comes up frequently in older Cape Coral, Fort Myers and Port Charlotte homes. Aluminum branch wiring is a separate, larger job not captured by this line; add it under “other” if it applies.

Whole-house repipe

Repipe prices depend on the number of fixtures, single-story versus two-story layout, slab versus crawl access, and how much drywall must be opened and patched. Most Florida homes are slab-on-grade, so supply lines are frequently rerouted through the attic and walls. This line covers supply piping; cast-iron drain lines under a slab are a different job — lining or replacing them can cost substantially more and should be added under “other” from a plumber’s quote.

Impact windows

The Florida-specific window range from Fixr is per window, installed. Large sliders, mulled units and doors cost more than a standard single-hung window; so does a home where openings must be re-bucked or stucco repaired around the frame. Many Southwest Florida owners compare impact windows with hurricane shutters; if you are pricing shutters instead, change the per-window figures accordingly. Opening protection can also improve a wind mitigation report and, with it, insurance premiums.

Flooring and interior paint

Both are entered per square foot of floor area. Luxury vinyl plank sits near the low end of flooring; porcelain tile and hardwood near the high end, before removal of old tile, leveling the slab or moving furniture. Paint pricing depends on how many rooms, ceiling height, color changes and drywall repair. These are the two items sellers most often do themselves, so if you are painting your own walls, set the paint line to your material cost only.

Kitchen and bathroom remodels

Remodel ranges are the widest in the estimator because “remodel” can mean new cabinet doors and a countertop or a full gut with relocated plumbing. Cabinets, countertop material, appliance tier and whether walls or plumbing move are the main drivers. If you are only refreshing a kitchen to sell — paint, hardware, a new faucet and lighting — lower the defaults sharply. For bathrooms, enter the number of baths you plan to touch, and remember that tile showers in older homes sometimes reveal rotted framing or failed pans once opened.

Septic tank and drainfield

Much of Lehigh Acres, Golden Gate Estates, North Port, Port Charlotte and rural Hendry and Glades counties relies on septic. A pump-out and minor repair costs little; a failed drainfield is another matter. In Florida, replacement systems must meet current setback and separation-from-groundwater standards, and where the water table is high, that can mean a raised mound or an engineered system — often above the national high figure. Florida’s onsite sewage program moved from the Department of Health to the Department of Environmental Protection effective July 1, 2021, so check the DEP onsite sewage program and your county for current permitting. Our page on selling with a failing septic system or well covers the selling side.

Pool resurfacing

Standard plaster is the low end; quartz and pebble finishes cost more, and tile line, coping and deck work add up quickly. Resurfacing does not include pool equipment, so a failed pump, filter or heater should go under “other.” Southwest Florida buyers look closely at pool cages and enclosures after storms; a screen enclosure repair is a separate trade and price.

Mold remediation

Fixr’s typical range covers jobs from a bathroom to a few rooms. Whole-house remediation after prolonged flooding can run far higher. In Florida, mold assessors and mold remediators are licensed by the Department of Business and Professional Regulation under Part XVI of Chapter 468, Florida Statutes, and assessment and remediation are separate roles. Fixing the moisture source — a roof leak, an AC drain, a plumbing failure — is a different line. See selling a house with mold for disclosure and process.

Drywall after a flood

After water intrusion, the common practice is to cut wet drywall at a set height above the waterline, dry the cavity, treat it and replace insulation and board. Enter the square footage of wall to be replaced, not floor area: a 10-foot wall cut two feet high is 20 square feet. Baseboards, doors, cabinets and flooring are separate items. For homes damaged by Ian, Helene or Milton, remember that substantially damaged properties in flood zones may face the FEMA 50% rule, which can turn a drywall job into an elevation or rebuild question — our guide to selling a hurricane- or flood-damaged house explains it.

Permits, dumpsters and other

Use the custom line for everything else: permit fees, dumpster rentals, junk removal, a cleanout, termite treatment, a screen enclosure, pool equipment, stucco repair, garage door replacement, or a cast-iron drain lining quote. You can enter a lump sum with quantity 1, or a per-unit price with a quantity.

Why Southwest Florida Prices Can Differ from National Averages

National figures are a midpoint across very different markets. Several local factors push Southwest Florida bids in either direction:

• Wind and flood codes. The Florida Building Code’s wind provisions shape roofing, windows, doors and garage doors throughout the region. Work in coastal flood zones can trigger elevation and floodproofing questions on larger projects.
• Post-storm demand. After a major hurricane, roofing, drywall and mitigation crews are booked for months, and prices and lead times rise. Quiet periods can bring sharper bids.
• Season. Many contractors are busiest in the winter when seasonal residents return; some offer better scheduling in summer.
• Salt air and humidity. Coastal exposure shortens the life of AC condensers, metal fasteners and screen enclosures, which can expand the scope once work starts.
• Housing age and construction type. Concrete-block homes from the 1970s through the 1990s in Cape Coral, Fort Myers and Port Charlotte are often due for the same group of system replacements at once.
• Access and logistics. Barrier-island and waterfront properties — Fort Myers Beach, Sanibel, Pine Island, Marco Island — can add travel, parking and material-staging costs.

Permits and Licensed Contractors

Most of the items in this estimator require a building permit in Florida: roof replacements, HVAC change-outs, water heaters, electrical panels, repipes, window and door replacements, and structural or septic work. Cosmetic work such as paint and many flooring jobs usually do not, but rules vary by city and county building department, so check before you start. Unpermitted work can surface later as an open-permit or code problem that complicates your sale; our page on code violations and unpermitted work explains why.

Florida licenses construction contractors through the Department of Business and Professional Regulation. Before hiring anyone, look up their license with the DBPR license search, confirm insurance, and get a written contract with a scope, price, payment schedule and permit responsibility. Florida does allow owner-builders to pull some permits for their own homes under specific conditions, but those rules carry obligations — read the building department’s disclosure carefully. Libera Capital Group’s team includes licensed contractors, which is part of how we evaluate repair scopes when we make an as-is offer; it is not a substitute for your own contractor or inspector.

Turning a Range into Real Bids

1. Start with an inspection. A pre-listing home inspection, a 4-point and a wind mitigation report tell you what buyers and insurers will see. Use them to decide which boxes to check.
2. Run the estimator twice. Once with only what an insurer or lender will require, once with everything you would want to fix to compete with updated homes.
3. Get two or three written bids for the big lines. Roof, HVAC, repipe, windows and septic are where estimates diverge most. Ask each contractor to itemize permits, disposal and allowances.
4. Replace defaults with bids. Enter each quote’s figure as both low and high, keep a contingency for the work not yet bid, and compare the total with what the repairs would add to your sale price.

Fix First or Sell As-Is?

Repairs make sense when they add more to the sale price than they cost — after the months they take and the carrying costs during that time. That is easiest to judge with numbers side by side. Take your estimated range into the net proceeds calculator: enter the repair total in the listing column and compare it with an as-is cash offer. Some repairs, such as a roof needed for insurability, may unlock a broader pool of financed buyers; others, such as a full kitchen remodel, rarely return their cost at resale.

Cash buyers estimate repairs too — it is one of the main inputs to any as-is offer. Read how we calculate our offer to see how a repair estimate fits alongside after-repair value and holding costs, and cash offer vs. listing for the wider comparison. If your house has several big-ticket items, you may also find our pages on roof and insurance problems, vacant properties and inherited homes useful.
