Step-by-Step Window Replacement Process
1. Assess Your Current Windows
Examine your windows for drafts, broken seals, warped frames, or visible damage. Determine whether the size, style, or type needs updating. McCann Window & Exteriors can provide a professional evaluation to identify the best replacement options.
2. Choose the Right Windows
Select windows based on energy efficiency, style, and durability. Popular options include double-hung, casement, slider, and picture windows. Leading brands like Pella, Marvin, Andersen, and Lindsay provide solutions that match the aesthetic of Northbrook homes while optimizing performance.
3. Schedule a Professional Consultation
A certified specialist will visit your home to take precise measurements, discuss design preferences, and recommend energy-efficient solutions tailored for your home.
4. Remove the Old Windows
Careful removal of the existing windows preserves the surrounding siding and trim. Professional installers ensure the opening is clean and prepared for the new window.
5. Install the New Windows
The new windows are placed, leveled, and securely fastened. Insulation and sealants are applied to prevent air and water infiltration. Professionals make sure each window is properly aligned and operates smoothly.
6. Finish Exterior and Interior Details
Trim, siding, and any exterior finishes are replaced or adjusted to integrate seamlessly with the new windows. The interior is cleaned, and any minor touch-ups are completed to maintain a polished appearance.
