Siding, Windows & Doors in Northbrook, IL

We are passionate about creating beautiful exterior renovations and will leave your home with nothing short of perfection.

Exterior Updates That Hold Up and Look Right Over Time

Siding, windows, and doors don’t all wear out at once, but they tend to show issues in similar ways. In Northbrook, homeowners often start noticing changes in how their exteriors look or perform. That might show up as siding that has started to fade or warp, windows that no longer seal tightly, or an entry door that feels out of place with the rest of the home. Over time, those smaller issues start to affect both appearance and performance. 

Erdmann Exterior Designs works with homeowners throughout Northbrook to address those issues through full exterior replacements, helping bring the entire exterior back into alignment both visually and functionally.

Exterior Services Built for Northbrook Homes

Erdmann Exterior Designs focuses on full exterior replacements, with each project planned around how the home looks and performs as a whole.

That includes:

Siding Replacement in Northbrook

Siding replacement is handled from material selection through installation. Erdmann works primarily with James Hardie fiber cement and maintains Elite Preferred Contractor status, reflecting both product knowledge and installation quality.

Window Replacement in Northbrook

Window replacement focuses on improving both performance and appearance. Erdmann installs products from manufacturers like Okna and Marvin, allowing homeowners to choose options that align with their home’s style and efficiency goals.

Door Replacement in Northbrook

A new entry door changes how the front of the home comes together visually. Erdmann installs ProVia doors, providing a more secure fit and a finish that aligns with the rest of the exterior.

Each service is approached as part of a larger system, rather than as a standalone upgrade, so the final result feels cohesive.

Serving Northbrook with a Consistent Approach

Erdmann Exterior Designs has been working in the Chicago area since 1982, bringing more than four decades of experience to homes throughout Northbrook and the surrounding communities.

That experience shows up in how projects are planned and executed.

Rather than treating each project as a one-off installation, the process is structured around:

• Understanding what is changing in the home and why

• Designing updates that work together visually

• Installing materials in a way that supports long-term performance

Erdmann holds an A+ rating with the Better Business Bureau, maintains James Hardie Elite Preferred Contractor status, and has been recognized on the Qualified Remodeler Top 500 list.

How Our Process Works

Many homeowners start the process without a clear plan, which is expected for projects of this scale. Erdmann’s process is built to provide clarity from the beginning and carry that through to completion.

A typical project includes:

• Consultation: A walkthrough of your home and what you’re looking to change

• Custom Renderings: A visual of your updated exterior before work begins

• Design & Selection: Finalizing materials, colors, and layout decisions

• Permitting & Scheduling: Coordinating requirements and timeline

• Installation: Completing the project with a clean, finished result

Each step builds on the previous one, so decisions are made with a clear understanding of the final outcome.
