Before Soffit Repair After Soffit Repair

The Problem You Can’t See (But Can Smell and Hear)

By the time the Muffoletto family reached out, they weren’t worried about color or style. They were worried about what was happening inside their walls.
They contacted Holda Construction in late summer 2024, after realizing that “one more repair” wasn’t going to change the way the house felt or smelled.
Their cedar siding was failing. Animals had chewed through it—more than once. A couple of woodpecker holes, flaking paint, and years of patch-style fixes had left the exterior tired and vulnerable. Inside, the situation felt worse:
  • A strong, unpleasant odor near the bathroom vanity that kept coming back
  • A different smell near a front window, especially after storms
  • The unnerving sound of chewing in the walls, right by where they put their baby down for a nap

As Mike put it later, as the couple caught up with us from the car on the way to their 10th anniversary retreat: Every time we make a hole in something, we have to take something else down.”

Every attempt at a small fix just exposed more issues behind it. They knew they were past the point where another coat of paint or a handyman repair would be enough. What they didn’t know yet was how deep the problems went—or who they could trust to solve them properly.

Choosing a Contractor in One Conversation

Mike found Holda Construction on Google, reading through reviews before deciding to call. He reached out on a Saturday or Sunday morning—and got a call back right away.

“He called back immediately Saturday or Sunday morning,” Mike recalled.

From there, the first interactions were all about education:

  • Mike and Julianna shared photos and walked us through the odors, noises, and visible damage.
  • We explained likely causes: trapped moisture, decaying material, and uncontrolled water around the house.
  • We set up options for in-person or Zoom meetings to fit their schedule.
They had planned to talk with other companies, and had already chatted with a few contractors who only did small repairs. But after meeting with Mariusz, they didn’t feel the need to keep chasing more quotes:
“We were going to engage others,” Mike said, “but we didn’t because we really liked Mariusz. We chatted with others who did small repairs, but didn’t need another quote.”
What stood out to them was how the process felt: the way options were explained, the way risk was laid out, and the way the entire project was broken into clear, manageable steps instead of vague promises.
Those early calls turned a stressful mystery (“Why does our house smell like this?”) into a clear plan. The moment logistics were finalized and materials were staged, our notes capture Mike as “so happy with working with them”—a good sign that the plan, cadence, and communication style were working.

Why They Chose Full Replacement

We looked seriously at two paths:
  • Patch repairs and a fresh paint job
  • Full replacement of the exterior wall system

Once the family saw the numbers and risks, they understood that “band-aid” repairs were going to approach the cost of replacement without solving the underlying issues. With:

  • Persistent, unexplained odors
  • Evidence of moisture and mold
  • Years of pest activity
  • A plan to stay in the home for the next 20+ years
…a full rebuild of the wall system was the only responsible choice.
They also came into the project with some hard-earned wisdom. As Mike put it,

“Nice guys doesn’t mean [they] will do the work well.”

For this project, they wanted both: people they liked and detailed, careful work that would hold up for decades.

What the Attic Revealed

Before committing to the full exterior replacement, we took a hard look at the attic, because that’s where comfort and odor issues often start.
There we found:
  • Insulation that was far below what the house needed
  • A large hallway / whole-house fan dumping hot air directly into a small attic cavity
  • Bathroom fans venting into the attic instead of outside
  • A stagnant section over the master bedroom with almost no real ventilation
In practical terms, the attic was acting like a closed thermos for heat, moisture, and smells. It helped explain why certain parts of the house never felt “right” and why odors lingered even after plumbing and surface-level fixes.
As Mariusz opened the awkward, unvented roof pocket above the entry and talked through options, the homeowner’s reaction was simple:

“He’s so good, so conscientious. No ventilation in that section, and maybe that will fix the problem.”

Because of that, the final scope didn’t stop at the walls. It included a targeted attic reset:
  • Professional vacuuming and removal of old insulation, dust, and debris
  • Air sealing around lights, wiring, pipes, and framing penetrations from the attic side
  • Removal of the large hallway fan and restoration of the ceiling so the interior looked original again
  • Rerouting bathroom exhaust so moisture now leaves the house instead of being dumped into the attic
  • A two-layer insulation strategy (batts plus blown-in), bringing the attic up to a high-performing R-value
  • Improved intake and exhaust ventilation—especially over the master bedroom—so the attic could finally breathe instead of trapping air and humidity

Scope & Selections

Siding
  • James Hardie fiber cement (HZ5) in Aged Pewter – a durable, low-maintenance upgrade that dramatically improved curb appeal.
Trim & Roof Edge
  • LP SmartSide soffits and fascia, finished to custom-match their Marvin windows, tying the entire exterior together with a sharp, cohesive look.
Wall System Corrections
  • Remove the existing cedar and inspect all underlying sheathing
  • Replace rotted and warped sheathing where needed
  • Install a continuous moisture barrier and properly detailed flashing to reset how the wall assembly manages water
Water Control
  • Install a new, oversized gutter system to end the “sheet of water” effect they had lived with during storms and better control roof runoff.

As Mike said about the old system: “The gutters were failing, water poured down in sheets.”

During demo and reconstruction, we moved carefully and verified each step, knowing the family was sensitive to odors and worried about hidden damage and signs of mice activity. As we opened walls, we documented everything with photos and videos, then walked the owners through what we saw.

Near the front window, for example, we opened up the siding and found mold on the inside drywall. We removed and replaced the affected drywall, repaired the wall assembly properly, and documented the change so they understood exactly what had been done and why.

At each stage, the agreement was simple from the homeowners’ side: “If you uncover something, please let us know.”

Our commitment in return: written change orders priced at Cost of Goods Sold (COGS), with minimal or no added margin—no back-door upsells, no gotcha invoices.

Milestones & Timeline

The project moved through a clear set of phases over roughly three weeks on site, scheduled for early fall after planning in August 2024.
Phase 1: From First Call to Contract
Homeowner sent photos, context, and a description of odors, pests, and water issues.
Educational call: we explained the risks, walked through options, and clarified what full replacement vs. repairs would look like.
Proposal shared via portal: clear scope, detailed line items, and a written “no-surprises” policy, including how change orders would work.
Permits and material logistics set up for a late-September start.
Protection plan for landscaping and driveway.
Careful removal of existing gutters and siding.
Real-time documentation (photos/video) of any damaged substrate or mold.
Sheathing repairs and replacements.
New moisture barrier and flashing.
James Hardie Aged Pewter siding installed.
LP SmartSide soffit and fascia installed in a custom color to match Marvin windows.
Oversized gutters installed, with particular focus on historical trouble areas.
Attic cleaned, sealed, insulated, and re-vented as part of the same overall workflow.
Final walkthrough.
Final photos, invoicing, and delivery of warranties and documentation.

Contract vs. Invoice — Transparency in Numbers

For large projects, the “real number” can get buried. Here, it didn’t.
  • Contract: $70,000
  • Change Orders: Only for documented discoveries (framing, painting, gutter protection, etc.), priced at actual cost of goods and services (COGS).
  • Final Invoice: Contract + approved, documented COGS-only changes, fully itemized.

The family appreciated knowing exactly how proposal, invoice, and change orders fit together—before any work started.

Most of the investment went into rebuilding the exterior envelope—siding, sheathing repairs, weather barrier, trim, and gutters—with a meaningful portion dedicated to professional attic cleaning, air sealing, and bringing insulation and ventilation up to a high-performance level. Interior finishing tied to the hallway fan removal was handled by a partner at contractor pricing and paid directly by the family, with Holda coordinating the sequencing so those pieces fit neatly into the larger project.

The “After” Story

After the project, the house didn’t just look new—it functioned like a new build.

  • Odor sources (trapped moisture, decayed material) were removed where found.
  • The wall system is now wrapped, flashed, and vented correctly.
  • Water is controlled instead of cascading in sheets during storms.

The attic is now clean, sealed, properly insulated, and breathing the way it should. Spaces that used to feel stuffy or unstable now feel consistent. The persistent smells near the bathroom vanity and front window—the ones that sparked the first phone call—are gone.

They can use their home like a home again—without wondering what’s hiding above the ceiling or behind the walls.

Their kids came away with surprisingly positive memories too. When Mariusz brought out a drone to diagnose a gutter issue from above, their seven-year-old son was fascinated; soon all three children knew him by name and would ask, “Is Mariusz coming!?”

It’s not a typical reaction to a major exterior and attic project—and that’s exactly why it stands out.

Their extended family noticed the details, too. At one visit, Julianna’s dad stood outside, pointed to a particular detail, and said simply, “See this? This is attention to detail.”

It wasn’t a grand feature—just the kind of small, thoughtful execution that tells you someone planned for how you really live in and touch the house.

Julianna’s summary is the one that matters most: “It feels like a brand-new house—but even more importantly, we know it’s protected and safe for our kids long-term.”

One favorite line from Mike captures their trust level going forward. He jokes that Mariusz “isn’t allowed to retire” before they need a new roof in 10–12 years.

Over time, the relationship has shifted as well. The family and the Holda team still cross paths in the community, including at church, and there’s an easy familiarity that comes from having gone through a complex, personal project together. What began as a call about a smell has become an ongoing connection with a contractor they now think of as a trusted neighbor.

Who Holda Was the “Right Fit” For in This Story

Looking back, the family says Holda Construction is the right fit for:
  • Homeowners who care about details and want a contractor who welcomes questions
  • Families who want clear explanations and written steps, not pressure and vague promises
  • People who want problems fixed at the cause, not just covered with new paint or trim

Mike’s own advice to other homeowners: “If I care about the details, then I need to ask the questions. Make sure you communicate.”

They also pointed out something they wish more people knew: internal plumbing issues often aren’t covered by insurance, so having a clear, documented scope and photo record matters when you’re investing your own dollars. And they love the idea that, when you see beautiful project photos online, there should be: “A list of people who would let you come to their house and see the work.”

That mindset lines up exactly with how they now talk about this project.

Next Step — Not Sure If Your Issue Is Cosmetic or Structural?

If you’re noticing strange odors, peeling paint, noises in the walls, or signs of water damage, the problem might be deeper than you think. The Muffoletto project is a reminder that smart renovations aren’t just about looks—they’re about solving real problems and protecting your family’s comfort and health.

Start with a photo review + consultation.

  • We’ll look at what you send, ask questions to understand the story behind it, and tell you what we suspect is happening underneath.
  • We’ll outline realistic options, including when a repair makes sense and when it’s time to think about a full system solution.

Conclusion

In the end, this project is less about siding and gutters and more about what happens when a house finally starts working with a family instead of against them. A problem that once felt murky and never-ending got pulled into the light, mapped out, and resolved in a way that will quietly pay off every time it storms, every time a window is opened, and every time someone walks up to the front door.

For homeowners, the real lesson is simple: when something feels “off” with your home, it’s worth investigating what’s happening beneath the surface—and it’s worth choosing a team that’s willing to go there with you, detail by detail. The Muffoletto project shows that when expertise, documentation, and craftsmanship line up, you don’t just improve how a home looks; you change how it feels to live there.
