During the job I was provided with updates and kept in the loop on the timeline for completion. The crew was great. They were courteous, worked hard, were respectful and careful with my home and surrounding property, and left the work site picked up and organized every night.

Lifetime replaced our old vinyl siding with new Hardieplank. It looks incredible!! Gino, John,  and the rest of the guys were great throughout the whole process. (They have an awesome paint person who helped us pick the best paint colors for our house!) We are so glad to have had Lifetime on our side!

“The thing that was the most impressive was the attention to detail and to making sure that our house was properly transformed up to Lifetime’s standards. There were times that Jose and his team would take pictures of parts of our soffit, or trim or siding that needed extra attention. They showed us the images to get approval to repair, and then they went for it, making sure that a perfect job went down. We are proud of our new looking home. We highly recommend Gino and Lifetime. They are great!”

Window Replacement FAQs for Portland Homeowners Questions:

What is the best window brand for homes in Portland?

We recommend Milgard® and Marvin®—two of the most trusted brands for Portland’s diverse climate and architectural styles. Milgard’s vinyl options like Tuscany™ and Trinsic™ are ideal for energy efficiency and affordability, while Marvin’s wood and fiberglass lines offer timeless aesthetics and high-performance insulation. 

These windows hold up beautifully through Portland’s rainy winters, hot summers, and seasonal shifts, making them a top choice for local homes in Portland & its surrounding areas.

Will new windows help lower my energy bills?

Absolutely. Replacing your old, drafty windows with ENERGY STAR® rated Milgard or Marvin products can lead to major savings—especially in Portland’s colder months and warm summer spikes. With better insulation and thermal performance, you’ll use less energy to heat and cool your home throughout the year, especially in older homes found in areas like Irvington, Hawthorne, Alameda and Eastmoreland.

Can I get cash rebates or tax credits for window replacement?

Yes. As a certified EnergyTrust of Oregon partner, we help Portland homeowners qualify for cash rebates on qualifying window installations. In addition, many of our ENERGY STAR® windows qualify for up to $600 in federal tax credits. We’ll guide you through the process to make sure you take advantage of every available incentive.

Do you use in-house crews?

Yes. At Lifetime Remodeling Systems, every window installation is completed by our dedicated in-house crews. Our teams work exclusively with us year-round, providing consistent craftsmanship, clear communication, and full quality control from start to finish. This approach allows us to deliver a smoother experience for Portland homeowners and maintain the high standards we’re known for across neighborhoods like Alameda, West Hills, and Sellwood.

How long does window installation take?

Most projects are completed in 1–5 days, depending on the number of windows and the scope of the work. We take special care in minimizing disruption to your home and keeping a clean, organized jobsite—especially in high-traffic Portland neighborhoods like Alameda, NW Portland, West Linn and Lake Oswego.

Can I replace just a few windows, or do I need to do them all at once?

Yes, we frequently work with homeowners who choose to replace windows in phases. Many Portland clients start with the rooms that feel drafty, outdated, or have the most visible wear, then move on to other areas as their schedule and budget allows.

Do you offer window styles that match older Portland homes?

Absolutely. We specialize in installing windows that maintain the historic integrity of homes in Portland’s classic neighborhoods—from Craftsman bungalows in SE Portland, to Colonials in NW Portland, and Mid-Century Modern homes in SW Portland. Our project consultants can help match window grid styles, finishes, and frame profiles to complement your home's original architecture.

Do you offer financing options?

Yes. We offer flexible in-house and third-party financing programs tailored for Portland homeowners. Whether you're replacing a few windows or upgrading your entire home, we can help you find a monthly payment plan that fits your budget.
