Sunroom Windows Costs And Prices

What do sunroom windows cost? This is a tricky question to answer because sunrooms can contain anywhere from 5 to 20 windows – therefore, replacement window prices are all over the board. For the sake of simplicity, we are going to use the number 10 as this is the number of replacement units. In this case, sunroom windows cost will range from $5K to $25K fully installed. Let’s delve further into the different price points for this topic.

Sunroom Windows Costs


Entry Level Cost (Excluding Installation)

Entry level replacement window costs range from $5000 to $8000 for the replacement window series themselves – not including install cost. This is for a entry level or mid range vinyl window with a limited number of color options and features. The glass package will be on the basic side, perhaps using a standard low-e glass.

— Price Range: $5,000 to $8,000 —


Mid Range Prices (Excluding Installation)

Entry level replacement window costs range from $8000 to $10,000 for the replacement window series themselves – not including install cost. This may include a quality vinyl, uPVC, composite or aluminum clad window. The glass package will be mid grade and have low-e glass, some sort of fill and use standard harware. The windows may be non-movable but you might have one or two single hung or double-hungs on the sides for ventilation.

— Price Range: $8,000 to $10,000 —


High End Pricing (Excluding Installation)

Entry level replacement window costs range from $10,000 to $15,000 for the replacement window series themselves – not including install cost. This assumes a well made aluminum clad, wood clad, steel, fiberglass or solid wood clad window from a well known known manufacturer. Upgrades may include double or even triple pane glass, foam insulation krypton fills, and a composite lift rail. At this price point, homeowners are probably opting for more expensive styles such as casements or awning window styles.

Installation Costs

Installation costs will run from $6,000 to $15,000 for our 10 “unit” example. If the project involves simply replacing existing frames the job will be on the lower side. If the installers need to prep, demo, frame, finish and mull frames together, the job will be extensive and will be at the higher pricing scale.

Milgard v Anlin

Hi there, we are replacing all of our windows and doors in our sunroom, which is in Northern California. It’s a pretty big job and it involves two patio sliding doors, two single hung windows, and one picture window. Well now that I say that, I guess it really isn’t that big a job. But the whole thing has to be redone. We have had a number of project quotes, but we’re down to two. The first is from Milgard and it uses Tuscany doors and Style line windows. The total cost is $9000. The other bid is from Anlin and uses the Malibu patio doors and the Panoramic windows. This bid is $9500. I was curious what you thought of these bids?

Janice – Homeowner – from 2023

[Site Editor’s Answer]

Janice, it sounds like the quotes are close enough that that’s the fair market price. I like Anlin more than I like Milgard so I would say pony up the extra $500 and go with the better brand and product(s). I think it will be worth it in the end. But make sure and check the reviews on the companies who will be doing the work of course. The installation is half the battle.

Sunroom Windows Cost Question

For the past three years I’ve been slowly restoring my 1500SF 1925 house in Mt. Washington, Baltimore, MD (sorely neglected for 20+ years before I moved in). We just had a deck added out back, which I figured was good to do before we redo the back porch to make into at least a three-season room. It’s not a large space, but I still want it to have the side door (existing, will be replaced), and change the back wall (half-solid, half screens) into probably two windows and a double/French (or dutch-style) door that opens onto the 10×23 deck.

I have an installer, though neighbors recommended a few as well. Kelemer uses Vytex, which you seem to like. My house is modest, and I do not need the best/fanciest, but I do need it to be practical and efficient; energy saving is important. Vytex Windows Reviews

Although my house is small, I’ve always loved those many-glass-paneled rooms on the bigger houses, and kinda want mine to look like that, for example:

I’m open to floor-to-ceiling units, and think I want to keep small panes to be consistent with the house. If you look here, mine is the first pic that comes up (green house in snow).

Elizabeth, in general, I would collect three to four bids and then see where you are in terms of the brands/series and the prices. Here are my good and great window recommendations…Once you get the bids, send them my way!
