the Pros.
Failing mortar lets water in. And water is "the most prevalent cause of deterioration" in old buildings — the National Park Service's words, not ours.9 We stop it at the joint.

Not our opinion. Three facts, footnoted — from the National Park Service, the standard insurance policy, and published repair bills.
A good repointing job “is meant to last, at least 30 years.”

Chicago's bungalow belt went up between 1910 and 1940 — 80,000 brick homes, nearly a third of the city.2 The typical American house was built in 1980.4
Never been repointed? You're three cycles past due.
Policies pay for sudden accidents. Not for things that wear out.
“Wear and tear, marring, deterioration.” Also “faulty, inadequate or defective… maintenance.”
Standard policy form5Generally not covered. Where it is, caps commonly run $1,000–$10,000.
Insurance Information Institute7“If rodents and insects chew on your house, your policy won't pay for the repairs.”
Texas Dept. of Insurance8“Homeowners insurance typically does not provide coverage for damages due to lack of maintenance from wear and tear.”

And where it gets in: “there is no substitute for proper filling of all mortar joints.”10
Same water. Different decade.
Warning signs
Brick is tough. The mortar isn't — it's built to wear out first, so the brick doesn't. Here's what losing that race looks like.

The diagnosis
Failing mortar isn't cosmetic. It's the first link in a chain — and the rest of it is documented by the EPA, the CDC, the National Park Service, and Chicago's own Inspector General. Every number is footnoted.
Chart No. 1996-ATP Patient Your house Presenting Crumbling joints Attending The Pros
Your joints are the wall's "first line of defense."1 When they fail, rain stops running off and starts soaking in.10
Water damage is one of America's most common claims — 1 in 67 homes a year, averaging $15,400.12 But rain through failed joints usually isn't a claim at all. It's just your bill.
The fix — tuckpointing, caulking & waterproofing before water finds the framingDry a wet wall within 24–48 hours and mold usually won't grow.13 A wall that re-wets every rain never gets the chance. And it grows where you can't see it — behind the drywall, inside the cavity.13
Remove mold without fixing the water and it comes back. That's the EPA and the CDC, not us.14 Researchers attribute 21% of U.S. asthma cases to home dampness and mold.15
The fix — stop the water at the joint, or you'll pay to remediate the same wall twiceWater expands 9% when it freezes.17 Every soaked crack becomes an ice wedge — pry, thaw, refill, repeat. The damage accumulates; it doesn't reset each spring.
Chicago hits freezing on roughly 120 days a year.18 And a crumbling joint holds water against the wall instead of shedding it — exactly what freeze–thaw needs.
The fix — repoint before winter; replace spalled brick with matched salvageA mouse fits through a nickel-sized hole. A rat, a half dollar. "Between the foundation and the ground" is on the CDC's own checklist.19 Illinois DPH is blunter — seal foundation cracks with metal or concrete.20
The part nobody mentions: the standard rodent-proof spec calls for brick joints filled with mortar.21 That's tuckpointing. Chicago spends $12.5 million a year on the problem, and its own Inspector General says poison won't fix it while the rats keep their shelter.22
The fix — seal gaps at grade with masonry, not foam from a canCarpenter ants don't eat wood — they nest in wood that stays wet. A colony indoors is "usually most important as a sign that there is or has been a water problem."23
Meanwhile the same gaps bleed money. Sealing air leaks saves an average of 15% on heating and cooling.24 Open joints and failed caulk are air leaks.
The fix — tight joints and fresh caulk at windows, doors, and penetrationsThe cascade
Every job below starts the same way: water past a mortar joint. The only variable is how long it ran.
The honest version: repointing isn't dramatically cheaper per square foot than rebuilding a wall. The escalation is masonry-to-structural. Mortar costs a few thousand. Framing, foundations, and mold are five figures — and none of them are covered.
What we do
One licensed, family-run crew from diagnosis to cleanup — no handoffs, no subs pointing fingers at each other.
We grind failing mortar to sound depth by hand, then repoint with mortar matched to your original — never smeared over the old.
Spalled brick replaced with matched salvage, bowed sections rebuilt, stone sills and copings reset and sealed.
Crowns, caps, liners, and dampers — up to full teardown-and-rebuild when the freeze–thaw got there first.
Rusted steel lintels replaced before they crack the wall above; parapets rebuilt before they lean.
Breathable sealers and fresh joints that keep water out — without trapping moisture inside the wall.
Fireboxes rebuilt in firebrick and refractory mortar, dampers replaced, smoke chambers parged — so the fire stays where it belongs.
Century-old facades brought back to spec without erasing their character. Residential and commercial.
Why the Pros
It's a promise about the estimate, not the mortar.
We fix what's failing. If it can wait five years, we'll tell you that too.
Color, texture, and strength matched to your original. The repair disappears.
Tarps down, dust controlled, site swept daily. Your neighbors will barely notice.
In writing. Same phone number since 1996.
How it works
A free on-site assessment. We walk every elevation, explain what's urgent and what isn't, and quote it straight.
The bad mortar goes. Joints ground to sound depth by hand — new mortar never gets smeared over old.
Fresh mortar, matched and tooled to your original profile. Cured right, cleaned up, backed in writing.
Neighbors talking
"They explained every step of the work and cleaned up beautifully at the end of each day."
"Small problems they found along the way were handled on the spot. No drama, no upsell."
"The new joints are invisible. A month later I honestly can't find where the repair starts."

The other side of the ledger
They age it by how it looks. There's a standardized scale for exactly that — and it ends somewhere most homeowners have never heard of.
Every appraised home gets a C1–C6 rating.25 At C6, Fannie Mae won't buy the loan until it's repaired.26 Deferred maintenance isn't a vibe — it's a field on a form. And at the bottom of the scale it stops being about price and starts being about whether your buyer can get a mortgage.
That last one is worth sitting with. In 2025 an Illinois court upheld $104,000 against a seller whose buyer found mold and rot after closing. Fixing the damage wasn't enough — he was obligated to find the source.29 Illinois sellers sign a disclosure form asking about exactly this.30
Which is the whole case for doing it right the first time. A cosmetic smear hides the source. It doesn't fix it — and six figures later, that distinction matters.
