  We've had several windows replaced by Classic Sash and Door Company and they've always done a great job. They are really helpful in finding the best product for our project and their workers are professional and left the site clean.

  Used Classic Sash to install top-end windows over the course of 10 years as my budget allowed. They matched their handwork, their professionalism, and the wood moulding & other materials every time over that span, an impressive feat.

  When we bought our home last year, a 1909 Victorian farmhouse in North Portland, most of the windows were painted shut. We explored restoring them because we thought that’s what we should do with an old home, but we were convinced of the value of replacing them after meeting with Bo Sullivan, an old home specialist at Classic Sash and Door.

Bo taught us so much about our style of home, its unique features and how Classic Sash and Door could replace the windows which would reduce noise and improve energy efficiency while preserving the original look. (In fact, he later emailed us some history and photos of our home dating back 100+ years. What a gift!)

Installation was a 2 day process. The installers were professional, friendly, and very thorough. It’s quite a job to fit square windows in wonky frames. Our new windows are beautiful, work great and definitely improve the look of our home. Can’t wait to save up the money to replace the rest!

  Got 7 new windows (bedroom and kitchen) and the service on the front and back ends was stellar. Oh, and the windows are great also.

  I’ve worked with Classic Sash and Door for two installs now. They do high quality work and are reliable and easy to work with. Mark has immense knowledge and can help navigate you through all the choices for your windows and doors. I would recommend them highly and will use them for any window and door work in the future.

  We have a 1911 craftsman bungelow that desperately needed a new front door. Bo was the designer that worked with us to make the right decisions for our old home so that we can work toward bringing her back to her original glory. Bo was incredibly nice, helpful, responsive, and knowledgeable about old homes through the entire process. If we could hire him to do everything in this house, we would! When it came time to go to Chown to pick out our door hardware, Bo met us there even though he really didn't need to do that (we were just confirming his suggestion; it wasn't an involved appointment). When you hear people say "went above and beyond," they are describing Bo! Email communication with everyone else at Classic has been helpful, timely, and friendly too.

Peter was our main carpenter and Sam was his associate on the first day. Peter explained everything they were going to do and then they set up and began the work. Our furniture/possessions were carefully protected from the work and they set up a very nice workstation in our driveway. Peter explained everything they did and how they designed everything to allow for siding changes in the future once the door was in place. The guys were completely non-obtrusive, which is amazing given what the work entailed. I had a meeting around the time that they finished for the day. Peter simply texted me that he locked the front door, put the new keys on the hook by the door, and left through our mudroom on the side of the house (which he could lock as he left). So considerate! Peter came back the next day to finish up some trim and the dentil shelf on the door and gave me the contact info for the painter they recommend for painting the trim and staining the door. Peter and Sam were punctual, respectful of the house, and incredibly nice. Most importantly, they did absolutely gorgeous work and I couldn't be happier with the new front door and sidelights. The rest of the house looks out of place now, but one day our beautiful door will be surrounded by an equally beautiful house that reflects the era in which she was built.

When it comes time replace the siding, we'll be replacing all of our windows. We've already talked to Bo about that and won't even bother going elsewhere for that job! Classic Sash & Door has a customer for life!

“This company? Well, wow – just wow. I had them replace a 1931 single pane gridded window that was huge (6’x7′). Naturally, the architecture of the home would not allow for just any new window install and certainly not even a high quality vinyl. It had to blend and not damage the surrounding interior framing which would have been difficult to match. Classic Sash knocked it out of the park. They were great to work with through every step of the process and offered up a fair price for this job without a constant “upsell routine” in order to get the best deal. The installers were competent and exceptionally neat with a clear eye for all the small yet important details. We couldn’t be happier and would recommend them in a heartbeat.”- SosaTV.

About Portland, Oregon

Portland, Oregon — affectionately known as the “City of Roses” — is a vibrant blend of natural beauty, creativity, and community spirit. Nestled between the sparkling Willamette and Columbia Rivers, Portland sits in the shadow of majestic Mount Hood, offering residents and visitors endless opportunities for outdoor adventure, from hiking and biking to kayaking and skiing.
The city is famous for its lush greenery, artisanal coffee, and thriving food scene — where local chefs turn farm-to-table dining into an art form. Stroll through neighborhoods like the Pearl District or Alberta Arts District to experience a mix of eclectic boutiques, vintage shops, and street murals that reflect the city’s unmistakable individuality. Portland’s many breweries and craft distilleries have earned it a reputation as one of the best beer cities in America, while its farmers’ markets and food carts showcase its dedication to local, sustainable flavors.
Beyond its creative culture, Portland leads the way in sustainability and progressive urban design. Its efficient public transit system, miles of bike lanes, and abundant green spaces — including the International Rose Test Garden and Forest Park, one of the largest urban forests in the country — make it a model for eco-friendly living.
Whether you’re exploring Powell’s City of Books, catching a show at the Keller Auditorium, or watching the sunset over the Portland Waterfront, this Pacific Northwest gem invites you to slow down, savor the moment, and experience life a little more thoughtfully.
