Most of Littleton’s housing went up between the late 1960s and early 1990s, a build era that brought aluminum sliding windows into almost every ranch home and split-level in neighborhoods like Columbine Knolls, Governors Ranch, and Ken Caryl. Those windows weren’t great insulators when they were new. Decades of Front Range sun, hail, and temperature swings later, they’re drafty, difficult to operate, and a significant drain on heating and cooling costs.
If that sounds familiar, we can help. We install replacement windows in Littleton, CO, from Marvin and Pella, and handle everything from the rough opening to the finished trim.
Aluminum sliders from the 70s and 80s are the most common thing we pull out of Littleton homes. No thermal break, oxidized frames, and seals are long gone. Single-pane glass in a Colorado climate means your furnace and AC are working against the window itself. HOA requirements add another layer — Ken Caryl Ranch, Governors Ranch, and Columbine Knolls all have approval processes for exterior changes. We know how that works.
We pull out the old units, check what’s behind the frame, and install the right product with proper flashing and sealing throughout.
Finishing a basement, adding a bedroom, or enclosing a patio? We handle new rough openings to code from the start.
Original trim on Littleton’s ranch-era homes is often dried out or painted over so many times that it’s due for replacement anyway. We handle it as part of the job.
Construction standards from the 1970s and 80s didn’t include much in the way of housewrap or modern flashing details. We check everything before new windows go in and correct what needs correcting.
Replacing aluminum sliders with a quality Marvin or Pella unit is one of the more noticeable upgrades a Littleton homeowner can make, both in comfort and on the energy bill.
Marvin is what we install on most Littleton jobs. The build quality holds up in high-UV climates, and their finish options work well for HOA communities where color matching matters.
Pella is a strong alternative where budget or project scope calls for it. Solid performance on the Front Range, good range of styles, and available in configurations that suit the ranch and split-level floor plans common throughout Littleton.
Both lines meet Colorado’s energy code and qualify for Xcel Energy rebates. We’ll walk you through which option fits your home before anything gets ordered.
The South Metro gets hit regularly. Littleton has seen significant storms roll through in recent years, and the damage isn’t always as obvious as a cracked pane. Frame denting, seal failure, and compromised flashing can all result from a hail event without any visible glass breakage — and that’s where water starts getting in without you knowing it.
We assess storm damage after it happens, document the condition of every affected window, and work directly with your insurance adjuster when a claim is involved. If you’re not sure whether your windows were affected, we can take a look and give you a straight answer.
We come out, walk the home with you, and assess every window frame condition, seal integrity, flashing, and trim. If you have original aluminum units, we’ll show you exactly what’s failing and what it’s costing you on your energy bill.
We go through Marvin and Pella options together — frame material, glass package, color, and any HOA considerations. Nothing gets ordered until you’ve signed off on exactly what’s going in.
Old windows come out carefully. Behind the frames of Littleton’s older homes, we regularly find deteriorated flashing and missing weatherstripping that needs to be addressed before anything new goes in.
New windows go in with proper flashing and sealing at every transition. Full-frame or insert installation, depending on what the rough opening requires.
Exterior caulk, interior trim, cleanup, and haul-away are all included. We leave the job site clean.
Littleton homeowners tend to stay put. The neighborhoods here are established, the homes are well cared for, and most of the people we work with are thinking long-term about what they put into their house. That’s exactly the kind of job we do well — right product, right installation, no shortcuts on the details that determine how long it lasts.

Your budget should align with performance, durability, and installation quality. Higher-end materials and complex installs increase cost but often deliver better long-term value.
Well-known brands like Marvin and Pella are known for balancing quality, efficiency, and design. The best value comes from choosing the right product for your home and climate.
Choosing standard-size vinyl windows and minimizing custom features keeps costs lower. Simple installations without structural changes also help reduce overall expense.
The off-season, especially winter, often brings better deals due to lower demand. Homeowners may also benefit from faster scheduling during this time.
Mild weather in spring and fall provides ideal conditions for installation. These seasons help ensure proper sealing and consistent performance.
