Chimney Waterproofing Colorado Springs Homeowners Can Count On
Waterproofed masonry lasts. Masonry sealed over trapped moisture breaks down faster.
Chimney waterproofing in Colorado Springs is not a product - it's a sequence. The sealer matters. But what matters more is the condition of the masonry before the sealer goes on. Apply the wrong product at the wrong time, and you lock moisture inside the brick. That accelerates the very damage the treatment was meant to stop.
Here's what many homeowners don't realize about chimney moisture protection: efflorescence - those white mineral deposits left on the brick face when water migrates through masonry and evaporates - is not just a cosmetic issue. It's evidence that moisture has already been moving through your chimney's structure. A surface showing efflorescence is not ready to seal. It needs to be read, cleaned, and dried first.
That's the standard we apply to every waterproofing job in Colorado Springs.

Why Colorado Springs Makes This Service Especially Important
Colorado Springs puts masonry through one of the most demanding moisture cycles in the state.
Late-spring snowstorms dump heavy, wet snow onto chimneys that haven't fully dried from the previous cycle. Then the sun comes out, temperatures spike, and the surface dries fast - hard and fast. That rapid swing pulls moisture deep into mortar joints - the packed material between brick courses that is the most porous part of any chimney - then forces it back out under pressure.
The freeze-thaw saturation cycle - the repeated process of masonry absorbing water, that water freezing and expanding inside tiny pores, then thawing - is the primary driver of masonry deterioration at this elevation. Pikes Peak weather patterns mean Colorado Springs properties experience this cycle more aggressively than lower-elevation Front Range cities. Black Forest and Falcon properties sit even higher and catch more precipitation. Manitou Springs chimneys face near-constant exposure to moisture-laden canyon airflow.
Our crew dispatches from 3595 E Fountain Blvd and reaches properties across this full range - from downtown's older masonry to newer construction in Briargate and Woodmen Hills.
A Waterproofing Job That Started With a Hard Conversation
The masonry told us it wasn't ready - so we said so before reaching for a single product.- Chimney Sweep Colorado Springs field team
A homeowner in the Old Colorado City neighborhood called about new white staining and crumbling mortar near the crown. She'd had the chimney's exterior treated previously - a coating was still visible on the brick face.
- 1The moisture readingsI climbed up and ran a moisture meter across the surface before anything else. The readings told the story. Moisture content inside the brick was high - well above the threshold where applying a sealer makes sense.
- 2The failed coatingThe previous coating had trapped vapor inside the masonry. Moisture trying to escape pushed outward, broke the seal from underneath, and accelerated the spalling.
- 3Prep firstWe didn't waterproof that day. We did a full surface prep first - cleaned off the failed coating, addressed a hairline crack in the chimney crown (the concrete cap poured across the top of the stack that sheds water away from the brick face), and let the masonry dry to confirmed readings over a follow-up visit.
- 4Then we sealedVapor-permeable masonry sealer - a product that blocks liquid water entry from outside while still allowing water vapor to pass outward from inside - applied in two coats across the full exposed brick surface area, crown edges, mortar joints, and ledges.
Six months later, the efflorescence was gone. The mortar joints were stable. That's what correct sequencing looks like.
What Happens When You Call Us About Chimney Sealing
We schedule a moisture assessment before we schedule a waterproofing application - always.
Some customers ask whether they can skip the assessment if the chimney looks dry from the ground. The answer is no - and the reason is straightforward. Ground-level visual inspection cannot tell you the moisture content inside a mortar joint. It can't detect a micro-crack in the crown that's been allowing water entry for one season.
Our CSIA certification covers chimney system diagnostics, including moisture assessment protocols. That means the evaluation follows a condition-based standard - not a blanket application schedule. When the surface is ready, we seal it. When it's not, we tell you what needs to happen first and why.
That answer is always honest. And it protects your masonry.
Moisture assessment
- Readings inside the mortar joints
- Condition-based, not a blanket schedule
- Sealed only when the surface is ready

- Can't detect a micro-crack in the crown
Our Waterproofing Standards
Every chimney sealing job at Chimney Sweep Colorado Springs follows the same non-negotiable sequence.
- Moisture meter readings taken across all exposed masonry surfaces before any product is selected
- Efflorescence identified and removed - mineral deposits must be cleared before sealer adhesion is possible
- Chimney crown inspected and treated as part of the application zone - not handled separately
- Vapor-permeable formulation selected specifically - never film-forming products that trap internal moisture
- Full coverage across exposed brick surface area: corners, ledges, mortar joints, and cap edges
- Surface prep and adhesion confirmed - masonry cleaned and dried to specification before first coat
Every job follows a three-phase sequence: assess, prepare, apply.
How the Waterproofing Process Works
Moisture Diagnostics
We arrive with moisture meters, not paint brushes. Readings are taken across the crown, brick face, and mortar joints. We document current moisture content, look for efflorescence and active staining, and assess the crown condition. If the chimney liner or flashing shows related concerns, we note those too - they affect the overall moisture picture.
Surface Preparation and Application
Clean, dry, ready masonry gets a vapor-permeable sealer applied in two full coats. Each coat covers the complete exposed brick surface area - including corners, ledges, and all mortar joint lines. The chimney crown receives its own treatment, sealed from the edges in to prevent water from sheeting down the brick face.
Post-Application Confirmation
We check coverage before we pack up. No thin spots at the corners. No missed mortar joints. No pooling at ledges. The goal is uniform, complete coverage that performs through Colorado Springs' temperature swings and snowmelt seasons without cracking or bubbling.

Sealing over wet masonry traps moisture inside and accelerates breakdown - the opposite of what waterproofing is supposed to do. Mortar joints are porous and can hold moisture long after the surface looks dry. Our CSIA-certified crew uses moisture meters to confirm readiness before any product goes on. Skipping that step voids the logic of the entire treatment.
Most jobs require two visits - one for the moisture assessment and surface prep, one for the sealer application. Each visit typically runs two to three hours depending on chimney size. If the masonry needs drying time between prep and application, the second visit is scheduled after confirmed readings drop to acceptable levels.
Vapor-permeable sealer allows moisture vapor to escape outward from inside the masonry while blocking liquid water entry from outside. Standard waterproofing paint forms a surface film that traps internal vapor. In Colorado Springs freeze-thaw conditions, trapped vapor builds pressure beneath a film coating and causes the surface to flake and crack faster than untreated masonry would.
No - efflorescence must be removed before any sealer is applied. White mineral deposits mean moisture is actively migrating through the masonry. Sealing over that surface traps the moisture pathway inside. We clean the staining, confirm the source, and dry the surface to specification first. Only then does sealer application make sense and perform as intended.
