Why Maddarini

What Makes Us Different in Missoula

There are a lot of contractors in Western Montana. Here's why homeowners choose Maddarini — and why it matters for your home and your investment.

📋

We Pull Every Permit

Skipping permits is common in Montana. We never do it. Unpermitted work can void your homeowner's insurance on a future claim and create problems when you sell. We protect you from that.

📍

Locally Owned & Operated

We live in Missoula. We're not a national franchise. When you call us in two years with a question, the same people who installed your siding will answer the phone.

🛡️

Licensed & Insured

Montana-registered contractor. General liability and workers' comp coverage on every job. You should always ask for proof of insurance before letting any contractor on your property.

💳

Flexible Financing

We offer financing options to make your project fit your budget. Most homeowners are surprised how affordable monthly payments are compared to the cost of waiting on damaged siding or failing windows.

📸

Reviews

What Missoula Homeowners Say

Real feedback from real homeowners across Western Montana.

★★★★★

"The crew showed up on time, finished ahead of schedule, and cleaned up everything. My house looks completely different. Three neighbors have already asked for their number."

Roy S. — Missoula, MT | Siding Replacement

★★★★★

"They were upfront about the price, pulled the permits themselves, and the install was clean. No surprises, no sales pressure. That's rare."

FAQ

Common Questions About Siding & Window Replacement in Montana

Answers to the questions Missoula homeowners ask most often.

Siding replacement in Missoula typically ranges from $8,000 to $25,000+ depending on your home's square footage, the material you choose, and the condition of the existing siding. A standard 1,500 sq ft home lands in the $12,000–$18,000 range. We provide free in-home estimates so you get an exact number for your specific home — no surprises.
Window replacement in Missoula typically runs $500–$1,200 per window installed, depending on size, style, and glass package. Most whole-home replacement projects for a standard Missoula home fall between $10,000 and $22,000. Contact us for a free in-home estimate.
Yes — most siding and window replacement projects within Missoula city limits require a building permit from the City of Missoula Building Division. Skipping permits can create issues with your homeowner's insurance and when you sell your home. Maddarini pulls permits on every job, without exception.
Premium vinyl siding with a minimum thickness of 0.044 inches performs best in Montana's freeze-thaw climate. It resists cracking and warping far better than standard 0.040" panels, and unlike wood or fiber cement, it won't absorb moisture or rot. We use 0.044" vinyl rated for 180 MPH wind on every siding project.
A standard siding replacement on a Missoula home takes 2–5 days. Window replacement typically takes 1–3 days depending on how many windows and whether any structural work is needed. We confirm your project timeline in writing before we start.
Yes. We offer financing options including same-as-cash plans so you can protect your home now and pay over time. Ask us about current financing programs when you schedule your free estimate.
