Vinyl Siding for Longmont Properties

Vinyl siding remains one of the most affordable and versatile siding options on the market, and it’s still a good fit for some Longmont homes. While it may not be as impact-resistant as fiber cement or engineered wood, today’s vinyl siding products are far more durable than earlier generations and come in a wide range of colors and profiles.

Advantages of vinyl siding:

Budget-friendly
Low maintenance—no painting required
Available in insulated versions to improve energy performance
Lightweight and easy to install

We work with trusted vinyl brands that offer fade protection and weather-resistant technology suitable for Colorado’s climate. While vinyl isn’t ideal for hail-prone areas, it can be a solid choice for rental properties or lower-risk zones.

Longmont Steel Siding

If you’re looking for virtually indestructible protection, steel siding is your best bet. It’s ideal for rural homes near open spaces, commercial buildings, or anywhere fire resistance and minimal maintenance are top priorities.

Steel siding provides:

Exceptional impact resistance (hail, debris, wind)
Class A fire rating
Sleek, contemporary design options
Rust-resistant coatings to handle snow and moisture

We install seamless steel systems and modern panel profiles that enhance any architectural style.

Cedar and Wood Siding

Longmont has a rich architectural history, and many older homes benefit from the timeless look of real wood. We work with Rocky Mountain Forest Products and Specialty Wood Products to offer premium-grade cedar and other wood options in lap, shake, and board-and-batten formats.

Can be painted or stained any color
Available in multiple styles and types of wood
Perfect for historic restorations or high-end exterior designs

Sunset Stone Siding

For homes that need a little something extra, stone siding and stone veneer are striking additions. Sunset Stone products are lightweight yet realistic, providing texture and contrast whether used as an accent or full-wall solution.

Adds value and high-end curb appeal
Fire-resistant and weather-tolerant
