Quality Work, Guaranteed
At Serrano Exteriors, we provide expert window installation across Minnesota, combining skilled craftsmanship with high-quality products built to last. Every window is installed with care to ensure maximum energy efficiency, durability, and curb appeal.
We stand behind our work with a 5-year workmanship warranty, and we honor all manufacturer warranties, which often include limited lifetime coverage on the windows themselves. That means you’re fully protected—both in product and installation.
Our Window Replacement Process
At Serrano Exteriors, we make window replacement in Minnesota simple and stress-free. Here’s a step-by-step look at how we handle your project from consultation to final inspection.
Free In-Home Window Consultation
Every project starts with a free, no-obligation consultation at your home. We’ll measure your current windows, identify the style (like double-hung, casement, or others), and test for lead-based paint if your home was built before 1978.
Free Window Replacement Estimate
Once we’ve gathered the information we need, we’ll provide a free window replacement estimate. This includes recommendations for styles, energy-efficient options, and available trim packages.
Window Ordering & Lead Time
If you move forward, we’ll place the order for your new windows. Most standard window orders arrive within 3 to 6 weeks. If you have custom sizes or unique styles, it may take a bit longer — but we’ll keep you in the loop the entire time.
Scheduling Your Window Installation
Once your windows arrive, we’ll schedule the installation date. We typically install in the order windows are received. Installation usually takes less than a week, depending on the size of your project and the trim package you selected.
Final Walkthrough & Inspection
After installation, our team completes a thorough clean-up, double-checks all fittings, and ensures smoke and carbon monoxide detectors are correctly placed. We’ll also coordinate your final inspection if one is required in your city.
FULL FRAME vs INSTERT
FULL FRAME
Also known as "new construction" or "complete replacement"
What It Is:
Full frame installation involves removing the entire existing window down to the studs—including the frame, trim, and casing—and replacing it with a
completely new unit.
Pros:
-
Replaces everything, including rotted wood or damaged frames
-
Best for older homes or when upgrading window size or shape
-
Maximum energy efficiency when paired with proper insulation
-
More design flexibility
Cons:
-
More labor-intensive and time-consuming
-
Higher cost
-
May require interior and exterior finishing
INSERT
Also called "pocket installation"
What It Is:
Insert installation replaces only the window sash, sliding it into the existing frame. The original frame, trim, and casing stay intact.
Pros:
-
Faster and less invasive installation
-
Lower cost
-
Ideal for frames in good condition
-
Less disruption to interior/exterior finishes
Cons:
-
Not suitable if the existing frame is damaged or out of square
-
Slightly smaller glass area due to the insert fitting inside the frame
-
Less flexibility in changing window style or size
