Professional Window Installation in Berwyn, IL
Choosing a quality replacement window matters, but installation is just as important to the finished project. Proper measurement, preparation, flashing, insulation, sealing, and finishing all contribute to how a new window looks and performs.
Valdicass specializes in professional Pella® window installation in Berwyn and throughout Chicagoland. As a Pella Platinum Elite Certified Contractor serving Chicagoland homeowners since 1997, we combine premium Pella products with careful installation and attention to the details surrounding each opening.
From protecting your home before work begins to completing the interior and exterior finishing included in your project, our team approaches window replacement as a complete installation—not simply replacing one window with another.
Our Window Installation Process
Every home and opening can be different, particularly in established Berwyn neighborhoods. Existing frames, trim, siding, masonry, previous replacement work, and conditions concealed behind the existing window can all affect the installation.
Our process begins by understanding those conditions and determining the appropriate installation method for the project.
1. Consultation & Product Selection
The process begins with a consultation to discuss your existing windows, the goals for your project, and the Pella products you’re considering.
We’ll help you compare appropriate options, which may include:
- Pella® Reserve™
- Pella® Lifestyle Series
- Pella® Impervia®
- Pella® 250 Series
- Window styles and configurations
- Interior and exterior colors
- Glass packages
- Grille patterns
- Hardware
- Screens
- Interior and exterior finishing options
We’ll also discuss whether pocket or full-frame replacement may be appropriate for the project.
2. Measurements & Project Verification
Accurate measurements are essential when ordering replacement windows.
Before ordering the right products, we verify the project specifications and window openings so the windows can be manufactured for the intended installation.
For projects involving unusual openings, structural modifications, or other special conditions, additional evaluation may be required.
3. Protecting Your Home
Window replacement happens inside and outside your home, so protecting the surrounding areas is an important part of our installation process.
Before beginning work, our installation team takes appropriate steps to protect work areas, including floors, furniture, and nearby surfaces, depending on the window location and project scope.
We work carefully during removal and installation and clean the work area as the project progresses.
Your home deserves the same attention as the windows we’re installing.
4. Removing the Existing Windows
We carefully remove the existing windows according to the installation method selected for the project.
For a pocket installation, portions of the existing window system remain in place and must be suitable to receive the new replacement window.
For a full-frame installation, the existing window assembly is removed to provide greater access to the opening.
Careful removal is particularly important in older homes where existing trim, finishes, masonry, siding, or previous replacement work may affect the opening.
5. Evaluating & Preparing the Opening
Once the appropriate components have been removed, the accessible opening can be evaluated and prepared for the new window.
Preparation varies based on existing conditions and the agreed project scope.
If previously concealed conditions are discovered that require work outside the original scope, the team can review them before proceeding with additional work.
This is more accurate than promising that every possible concealed repair is automatically included in a standard window installation.
6. Installing the New Pella Window
The new window is positioned, leveled, secured, and installed according to the requirements applicable to the product and installation method.
Attention to alignment matters not only for appearance but also for proper window operation.
Before finishing the opening, check the window for proper operation and positioning.
7. Flashing, Insulation & Sealing
The details around the window are an important part of the installation.
Depending on the project and existing construction, the installation may include applicable flashing, insulation, and sealing around the window opening.
These components help integrate the new window with the surrounding wall system and help manage air and water at the opening.
This is one of the reasons we believe:
Premium products deserve expert installation.
8. Interior & Exterior Finishing
A replacement window should look finished from both sides of the wall.
Depending on the installation method and contracted scope, finishing can include interior trim, exterior trim or capping, sealants, and other details necessary to integrate the new window with the home.
For projects involving Pella wood windows, we can pay particular attention to coordinating the new window with existing interior trim and finishes.
9. Final Inspection & Cleanup
Before completing the installation, we check the newly installed windows and applicable finishing details.
We clean the work area and remove installation debris associated with our work, per the project scope.
We can also review basic window operation and features with the homeowner.
Full-Frame vs. Pocket Window Installation
One of the most important decisions is how to replace the existing window.
Pocket Replacement
A pocket replacement installs the new window within an existing frame that can remain.
This can reduce the amount of surrounding material that needs to be disturbed, but it also means that portions of the existing window assembly remain in place.
Full-Frame Replacement
A full-frame replacement removes the existing window assembly and provides access to the rough opening.
This approach may be appropriate when:
- Existing frames are deteriorated
- Previous installations have affected the opening
- Existing conditions need to be exposed
- Window size or configuration is changing
- A more comprehensive replacement is desired
Valdicass can evaluate existing conditions and explain which installation method best fits the project.
Window Installation in Older Berwyn Homes
Established homes can present conditions that aren’t always found in newer construction.
Existing openings may be out of square, trim may have been modified over the years, previous replacement windows may already be present, or the materials surrounding the window may require additional consideration.
That’s why we don’t assume every opening needs the same installation.
We evaluate your home’s conditions and coordinate the Pella product and installation method accordingly.
