Expert Stucco Remediation in Montgomery & Chester County, PA
Why Stucco Fails in Montgomery County Homes (And How We Fix It)
Southern Pennsylvania has one of the highest concentrations of stucco failure in the country and homes built between 1990 and 2010 in Montgomery and Chester County are at the center of it. Rushed installations, missing flashing details, and improper water management systems left tens of thousands of local homes vulnerable.
The damage is not always visible from the outside. By the time you notice dark streaks, soft spots near windows, or cracks along corners, water has often been working behind your walls for years rotting OSB sheathing, growing mold, and silently degrading your home’s structural framing.
At Merman Construction, we specialize in full stucco remediation not surface patches. We remove the failed system down to the studs, document every inch of underlying damage, and rebuild your exterior with modern water managed materials backed by manufacturer warranties.
If you are in Collegeville, Phoenixville, Royersford, Blue Bell, Lansdale, Skippack, Ambler, or Malvern and have concerns about your stucco, we will give you an honest assessment with no pressure.

Stucco damage is almost always worse than it looks from the outside. The sooner it is addressed, the less structural repair you will need and the lower your total project cost. We have helped hundreds of homeowners across Montgomery and Chester County stop the damage before it spread. Reach out today to schedule a no pressure assessment.
Our Stucco Water Damage Repair Process: An Industry Best Practice for Stucco Remediation
Step 1: Full Moisture Assessment
Every stucco remediation starts with a thorough assessment of your home’s exterior. While some moisture issues are visible on the surface, others are only fully revealed once work begins. That is completely normal and expected with homes of this age in our area. What sets Merman Construction apart is that we walk you through everything we find as the project unfolds, so you are never caught off guard. Our goal is a clean, complete repair with no lingering issues behind your new exterior.
Step 2: Material Selections for Your New Exterior
Because remediation involves removing the entire failed cladding system, you will choose your replacement material before work begins. Most clients select James Hardie® fiber cement siding, engineered specifically for the mid Atlantic climate. Others choose premium vinyl or a combination with manufactured stone accents. We will show you completed projects in your neighborhood so you can see exactly how each option looks.
Step 3: Full Remediation and Rebuild
We strip the failed cladding down to the studs, replace any rotted OSB or plywood sheathing, and install Benjamin Opdyke HydroGap® drainable housewrap which drains bulk water 100x faster than standard housewrap. Every window, door, and penetration is properly flashed using HydroFlash® GP. No shortcuts, no hidden rot left behind.
Step 4: Final Inspection and Punch List Review
We do not call a project done until it passes our internal quality review and yours. You walk the job with us before we close out. Every item on the punch list is resolved before our crew leaves the site.
Stucco Remediation Serving Montgomery & Chester County Communities
Why Stucco Fails in Montgomery County (and How We Fix It)
If you own a home in Montgomery or Chester County built between 1990 and 2010, you are likely living in the “Stucco Danger Zone.” The failure we see isn’t usually the stucco itself, it’s what is missing underneath.
At Merman Construction, we don’t just patch cracks. We specialize in full-scope remediation that corrects the structural omissions common in local developments.
The “Hidden” Rot We Find in Local Homes:
-
Missing Kick-Out Flashing: Many original builders in developments like those in Blue Bell and Gilbertsville failed to install kick-out flashing where rooflines meet vertical walls. This channels bulk water directly behind the stucco, rotting the OSB sheathing for years before you see a spot inside.
-
Improper Window Flashing: We frequently find windows that were simply “taped” over the house wrap rather than integrated into a true drainage plane. We replace these with high-performance window flashing systems that direct water out, not in.
-
The “Double Vapor Barrier” Trap: Some older homes have plastic vapor barriers on both sides of the wall, trapping moisture inside the stud cavity. We correct this by installing “breathable” house wraps (like Benjamin Opdyke HydroGap®) that allow the wall to dry out.
We serve homeowners throughout Montgomery and Chester County including Collegeville, Phoenixville, Royersford, Blue Bell, Lansdale, Skippack, Ambler, Malvern, Gilbertsville, and Worcester.

Estimate Stucco Remediation Costs
Stucco remediation costs can vary widely because the finished siding or stone is only one part of the project. The real cost depends on how much stucco needs to be removed, what damage is found behind it, how many windows and doors need to be integrated, and what exterior material is selected for the rebuild.
This planning guide gives homeowners in Montgomery County, Chester County, and nearby Pennsylvania communities a general cost range based on exterior square footage, replacement material, hidden damage allowance, and whether window replacement should be considered during the remediation.
- Use the approximate square footage of the stucco area being removed, not the full interior square footage of the home.
- Costs may increase if there is hidden sheathing damage, framing repair, window replacement, stone veneer, or complex trim work.
- Replacing windows during stucco remediation can make sense when older windows, failed flashing, or future exterior rework are concerns.
This stucco remediation cost calculator is designed for general planning only. Actual pricing depends on the condition of the wall behind the stucco, window and door details, siding or stone selection, access, and the amount of hidden moisture damage discovered after removal.

These ranges are for early planning only. A formal estimate depends on actual wall conditions, access, window and door flashing details, selected materials, and the amount of hidden damage discovered after the stucco is removed.

Frequently Asked Questions
Answers to what Montgomery and Chester County homeowners ask most about stucco remediation.
-
Stucco repair addresses surface-level cracks and cosmetic damage. Stucco remediation goes much further — we remove the failing stucco completely, inspect and repair the underlying structure for moisture damage, install a proper drainage plane and weather barrier, and apply new siding. In southeastern Pennsylvania, where improper original installations are widespread, full remediation is almost always the right long-term solution.
-
Common warning signs include dark staining or streaking below windows, soft spots when you press on the stucco, visible cracks or gaps at window and door frames, a musty smell inside exterior rooms, or peeling interior paint on outside walls. If your home was built between 1995 and 2010, we recommend a professional inspection even if damage isn't obvious yet.
-
Most full stucco remediation projects in Montgomery and Chester County range from $25,000 to $75,000 or more depending on the size of the home, extent of moisture damage, and the replacement siding chosen. We provide detailed, itemized estimates before any work begins so there are no surprises.
-
We most commonly install James Hardie® fiber cement siding, which is engineered to resist moisture, insects, and the freeze-thaw cycles common in southeastern Pennsylvania. Stone, CertainTeed vinyl, and other durable systems are also available depending on your home's style and budget.
-
Stucco remediation does not require a permit. It is considered an exterior repair and replacement, not a structural change. This means work can typically begin more quickly without waiting on township approvals — one less thing for you to worry about.
-
A typical residential project takes two to four weeks on site. The timeline depends on the size of your home, how much structural repair is needed, and weather conditions. We'll give you a detailed project schedule with your proposal so you know exactly what to expect from start to finish.
-
Yes, significantly. Unresolved stucco failure is a major red flag for buyers and home inspectors in this region. Completing remediation protects your sale price and removes a major contingency issue. Many homeowners also find that updated siding improves curb appeal and appraisal value.
-
Yes. Merman Construction Inc. is fully licensed (PA License #066259) and insured for stucco remediation and exterior remodeling in Montgomery and Chester Counties. We've completed remediation projects across Collegeville, Phoenixville, Royersford, and surrounding communities.
