Why Philadelphia Homeowners Can’t Afford to Wait

Water is the #1 enemy of Philadelphia chimneys. Rain, snow, and ice penetrate porous brick and mortar, then freeze and expand — cracking masonry from the inside. Waterproofing creates an invisible barrier that stops water penetration while allowing internal moisture to escape. It's the single best way to extend your chimney's lifespan and prevent costly structural repairs.

#1 Enemy

Water Destroys Chimneys

Rain, snow, and ice penetrate porous brick and mortar, then freeze and expand — cracking masonry from the inside out.

5 Years

Waterproofing Warranty

Our vapor-permeable sealant blocks water while letting moisture escape. Protected for 5 full years.

$15K+

In Prevented Damage

Waterproofing typically pays for itself in the first year by preventing freeze-thaw structural damage.

Every week you wait, the damage gets worse — and the repair gets more expensive.

Brown stains were spreading across my living room wall every time it rained hard. Turns out water was wicking through the chimney masonry. They applied a breathable sealant to the entire exterior. Two months and several storms later — not a single new stain.

Damp musty smell in the family room every time it rained. We thought it was the basement. Turns out moisture was coming through the chimney masonry above. Franklin waterproofed the exterior and the smell is gone. Should've looked up sooner — literally.

Our house is only 12 years old but the builder never sealed the chimney. We were already seeing mortar deterioration. Franklin waterproofed it before any real damage happened. Preventive maintenance is way cheaper than emergency repairs. Learned that lesson the easy way for once.

Water was pooling at the base of the chimney where it meets the roof. The mortar at the bottom three courses was turning to sand. They repointed the damaged area, sealed the chimney-to-roof transition, and waterproofed the entire stack. Problem solved.

Had spalling bricks repaired on the chimney and Franklin recommended waterproofing as part of the project. Smart call — they said the new mortar needs protection just like the old stuff. One crew did both jobs in the same visit. Efficient and cost-effective.

Our chimney faces north and takes a beating every winter. After seeing what freeze-thaw did to my neighbor's chimney — $9,000 in repairs — I decided to be proactive. Franklin waterproofed mine for a fraction of that. Five-year warranty. Money well spent.

We were getting dampness on the interior wall behind the chimney, especially after heavy rain. Franklin tested the masonry with a moisture meter, confirmed it was absorbing water like a sponge, and applied their breathable sealant. Three nor'easters since then — completely dry inside.

After the freeze-thaw cycle last winter I had mortar crumbling off my chimney in chunks. They explained how water gets in the pores, freezes, and blows the mortar apart over time. Repointed the damaged joints and waterproofed the whole thing. Said it should hold 8-10 years now.

White streaks running down my chimney for years. Turns out that's called efflorescence and it means water is pulling minerals through the brick. Franklin cleaned the staining, repaired a few soft spots, and sealed everything. Chimney actually looks better now than when we bought the house.

After the nor'easter knocked some bricks loose, I expected to wait weeks for a mason. They were out in two days, matched the existing mortar color perfectly, and even sealed the crown while they were up there. Top-notch craftsmanship.

They showed me video footage from inside my chimney — I could see the cracks they were talking about. No pressure, just facts. The repair was done in one day and they cleaned up everything. First contractor I've ever tipped.

Common Questions

Answers Before You Call

The NFPA recommends annual inspections. In Philadelphia, our freeze-thaw cycles and aging masonry make this especially important — even if you rarely use your fireplace, animals, debris, and moisture can cause hidden damage. An annual check catches small problems before they become expensive emergencies.

Book your annual inspection — $69
