Chimney Repair Estimating Softwarefor Philadelphia Contractors
If you're bidding chimney repair in Philadelphia, the gap between a job that nets margin and one that doesn't usually comes down to underestimating mortar deterioration — and how you handle heavy snowfall requires strong roof load capacity. Drop a plan set in, walk away for 8 minutes, come back to a priced bid you can defend.
What Philadelphia does to a chimney repair bid
Cold winters with heavy snow, warm humid summers. Temperatures swing 20°F - 85°F, rainfall runs 40-50 inches, and inspectors here are working off IRC R301.2 / IECC Zone 5. None of that shows up on a plan symbol legend — but it changes your fastener schedule, your waste factor, and whether the building department signs off on the rough.

Watch-out specific to this market
Underestimating mortar deterioration. In Philadelphia that gets worse because heavy snowfall requires strong roof load capacity, and IRC R301.2 / IECC Zone 5 (frost depth 48 in. minimum, R-49 attic, ice-shield first 24 in. past wall plate) won't let you patch around it after the fact. Catch it at takeoff or eat it on the punch list.

Stuff Philadelphia chimney contractors ask before they sign up
Does this respect PA code, or do I have to re-cut every quantity?
Counts assume IRC R301.2 / IECC Zone 5 (frost depth 48 in. minimum, R-49 attic, ice-shield first 24 in. past wall plate). PA doesn't license chimney repair at the state level, so the variability comes from local amendments. Quantities are correct; you adjust crew rates and local permit assumptions in the bid summary.
How do you handle assessing masonry deterioration extent?
The model reads the plan once, counts symbols against your assembly library, and surfaces the count for review. You override anything that looks off before it hits the quote. For historic work in Philadelphia, the typical correction is one or two assemblies — not redoing the whole thing.
What about heavy snowfall requires strong roof load capacity?
Steep pitches (6:12+) recommended for snow shedding. Ice and water shield required in first 3 feet from eaves. Architectural shingles withstand freeze-thaw better than 3-tab.
How much does a permit add to a chimney repair job around here?
Plan on $300–$8,000 in Philadelphia, with review running 4–8 weeks. Build that into general conditions so a slow plan-check doesn't eat your overhead. Insurance and bond are separate carrying costs.
