Replacement Windows in Longmont.
Built for Wind & Weather.

In Longmont, homes face strong seasonal winds, intense Colorado sun, and fast temperature changes that can expose weak seals fast. Your windows, siding, and doors should reduce drafts, stabilize indoor comfort, and protect your home’s exterior year after year. If you’re battling cold spots, sticky windows, faded finishes, or skyrocketing utility bills, your exterior envelope may be overdue for an upgrade.

Longmont Siding Installation

Protection That Holds Up to Colorado Storms.

Longmont weather can punish exterior surfaces—especially after hail and long sun exposure seasons. When you notice cracking, fading, or hidden damage beneath older siding, replacement becomes a chance to upgrade the entire exterior shell.

We install advanced fiber cement and engineered wood siding options that deliver stronger impact resistance, improved stability, and a cleaner finished look that fits your neighborhood.

Common Questions from Longmont Homeowners

Wind, sun exposure, and storm seasons raise practical questions. Here are honest answers to what we hear most often in Longmont.

Absolutely. We replace windows year-round using a “one-out, one-in” method to minimize heat loss and keep the home protected.

If we find hidden rot or water damage, we show you the issue and explain repair options before moving forward—so your new windows have a solid foundation.

We protect floors and furniture, clean thoroughly as we go, and haul away old materials—leaving the work area clean.

Most projects are completed in 1 to 2 days. We’ll give you a clear timeline during your consultation based on window count and conditions.

For many Longmont homes, yes. Triple-pane can improve insulation and reduce drafts—especially in wind-exposed rooms and older homes.

Depending on the scope, permits may be required. We handle permitting when needed and provide documentation to support HOA review.

We often recommend Fiber Cement (James Hardie) or Engineered Wood (LP SmartSide) for strong durability, impact resistance, and long-term curb appeal.

Modern doors use stronger frames, upgraded lock hardware, and tighter weather seals—so you get better security, fewer drafts, and improved comfort.
