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, Ken Caryl, and parts of Roxborough. 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 the first thing you notice when a room won’t hold its temperature.
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. A single-pane aluminum slider with no thermal break conducts cold straight through the frame, which is why the sill feels cold to touch in January even when the room is warm. HOA requirements add another layer: Ken Caryl Ranch, Governors Ranch, Grant Ranch, Columbine Knolls, and Roxborough 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.
Going from an unbroken aluminum frame to a modern insulated unit is one of the bigger single-step improvements available on a house of this era. The comfort difference is immediate; the bill difference is real but gradual.
Marvin windows are what we install on most Littleton jobs. The finish range is broad enough to match what an HOA has already approved elsewhere in the neighborhood, which matters more here than in most markets.
Pella windows are the alternative where budget or scope calls for it, with configurations that suit the wide openings and sliding arrangements common on ranch and split-level plans here.
Eligibility for compliance or a rebate relies on the U-factor and SHGC, not the frame badge. We verify these figures against NFRC labels and current requirements before ordering.
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 lifted flashing can all follow a storm with the glass still intact. On an aluminum slider, the frame dents easily, and once the track deforms, the sash stops sealing even though nothing looks broken from the inside.
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 and helps ensure proper sealing and consistent performance. For HOA communities like Ken Caryl Ranch, Governors Ranch, Grant Ranch, Columbine Knolls, and Roxborough, factor in additional lead time for design approval before scheduling.
