Roofing
What drives roof replacement cost
Size, pitch, material, tear-off, complexity, region, and timing — ranked by how hard each one moves your final bill.
Cost guides
The calculators give you a number; these guides give you the judgment around it — what moves prices in roofing, painting, plumbing, HVAC, and electrical work, how materials compare over decades, and how to tell a fair bid from a padded one.
Roofing
Asphalt vs. metal roofing
Metal costs 2-3x more up front but can last 2-3x longer. The honest comparison is dollars per year of roof life — here's that math.

Reading a roofing quote
What a legitimate roofing bid must itemize, the red flags that predict change orders, and the questions that separate pros from pretenders.
Painting
Cabinet painting vs. replacement
Professional cabinet painting runs $2,000–$6,500; replacement runs $8,000–$25,000 installed. Here's the math and the honest tradeoffs.
Painting
Deck staining cost
Professional deck staining runs $2–$6 per square foot in 2026 — about $900–$1,500 for a typical 300 sq ft deck. Here's the line-by-line math.
Plumbing
Sump pump costs
Replacing a sump pump in an existing pit runs $650-$1,200; first-time installs $800-$3,000. The submersible vs pedestal math, itemized.
Plumbing
Sewer camera inspection
What a sewer scope costs in 2026, what roots, bellies, and cast-iron scale on the video actually mean, and the repair-or-replace decision tree.
Plumbing
Slab leak repair cost
What detection, a tunneled spot repair, and a full repipe each cost — and the math for deciding which one your house actually needs.
HVAC
Heat pump vs. gas furnace cost
Installed heat-pump costs from published 2026 equipment prices, and the cost-per-million-BTU math that shows when leaving gas or oil actually pays.
HVAC
Ductwork replacement cost
About $1-2 per square foot of home for whole-home replacement, $25-55 per linear foot of duct — and when sealing beats replacing.
HVAC
Furnace replacement cost
Installed gas-furnace costs from published 2026 list prices — 80%, 96%, and 97% AFUE — plus the fuel math that says which efficiency tier actually pays.
Electrical
EV charger installation cost
What a Level 2 charger really costs installed — $800–$2,200 for most garages, $1,500–$3,500 with panel work — itemized down to the outlet and permit.
Plumbing
Trenchless vs open trench
Pipe bursting, CIPP lining, and the dig priced on the same 50-foot run — and how lawn, driveway, or slab above the pipe picks the cheaper method.
How guides are written and reviewed
Each guide is grounded in the same data trail as the calculators (see methodology), carries a visible review date, and is updated when the underlying pricing data is refreshed. No guide on this site is written to sell you a product or a contractor's phone call.
