St. Paul Window Repair, Restoration & Replacement

Name: Apex Window Werks
Brand: Apex Window Werks
Rating: 4.8 (3405 reviews)

At Apex Window Werks, we provide expert window repair and restoration in St. Paul, MN, from Summit Avenue and the Historic Hill District to Highland Park, Como and Merriam Park. Victorian sash restoration, stained and leaded glass repair and period joinery are what we do here.

St. Paul has some of the most significant nineteenth-century residential architecture in the country, much of it inside designated districts where exterior changes can be reviewed. That makes restoration the practical route as well as the right one — and it means the trade required is joinery, not window fitting.

Window Repair, Restoration & Glass Replacement in St. Paul, Minnesota

St. Paul holds some of the most significant nineteenth-century residential architecture in the country, and Summit Avenue is the best known stretch of it anywhere. The Historic Hill District, Cathedral Hill and the streets running off them carry Victorian, Romanesque and Queen Anne houses with tall wood sashes, curved and stained glass, and joinery that no catalogue window will ever reproduce. Further out, Highland Park, Como and Merriam Park bring 1920s to 1950s housing with its own distinct needs.

Victorian Sash Restoration and Historic District Work in St. Paul

On a St. Paul historic house the window is part of the architecture, and it is treated that way: the sash comes out, is stripped, repaired or replicated where members are missing, re-glazed around its original glass, re-corded and weatherstripped. Curved, stained and leaded panels are repaired in place wherever possible. Because much of this housing sits inside designated districts where exterior changes can be reviewed, restoration is frequently the only practical route as well as the right one. Newer parts of the city get conventional sealed-unit and hardware service.

Ice dams are a familiar winter headache in St. Paul, and they’re a reminder of how hard the season is on a home’s envelope. As snow melts and refreezes along the roofline, water backs up and moisture pressure builds against windows and doors, while deep cold stresses seals and swells aging wood. Historic homes along Summit Avenue and throughout Highland Park feel it acutely. We respond with a free on-site assessment, determine what has actually failed, and repair it where we can instead of recommending full replacement. Serving Ramsey County, we complete most repairs in a single visit, clean up carefully afterward, and stand firmly behind the repair we provide.

Reviews

Apex experts came by quickly, were professional, and finished the estimate on the spot. The office followed up with me over the next few weeks as I wasn't ready to make a decision. I then affirmed to move ahead, they scheduled within a week. The installation crew was polite, and professional and did great work. The cost was a good value for the work done. I would highly recommend it. I'm delighted to have my two windows fixed. The one I can open again and the other I can see clearly out again.

Joanne Couture, Arlington Heights, IL

Apex Window Werks replaced the foggy glass on our kitchen window. They carefully removed the old glass pane and installed a new one, ensuring precise measurements and using silicone to secure it properly. From the first person I spoke to on the phone, to the couple of gentlemen who installed the glass, everyone was easy to talk to and they were all very professional. Highly recommended!

Ofelia Miguel, Joliet, IL

Service technicians were polite and professional. They removed damaged parts of the window, cut new pieces to fit, stained the wood, and installed them nicely. The team cleaned up as if they were never there. I would recommend Apex Windows Werks for your window repair. Friends living near me ordered window repairs based on my recommendation as well.

Glenn Kaupert Chicago, IL

Had someone come out to look at a few windows I’m having issues with - none of them needed a full frame replacement at the moment but the technician was incredibly kind and informative. The technician determined that replacing the entire window frame was not necessary, which saved me both time and money. I feel confident about caring for my current windows, I know what to look for to let me know replacements are needed, and I will definitely be coming back to Apex when that is the case. Thank you!

Alyssa Nickow, Elgin, IL

I was thrilled that Apex Windows Werks had the right parts, and was able to come right out and repair my window on site. They were very prompt, and they saved me quite a bit of money over the replacement quote I got from another window company that didn’t do repairs.

Common questions
about window & door service

My house is in a designated historic district. What can I actually do?

Restoration, in almost every case. Exterior changes in St. Paul’s historic districts can be subject to review, and replacing original windows is the change most likely to be questioned. Restoring the existing sash leaves the elevation unaltered, which sidesteps the issue entirely.

Can stained and curved glass be repaired?

Yes. Stained and leaded panels are re-leaded and re-puttied, and individual lights replaced without disturbing the surrounding work. Curved glass is specialist but obtainable, and we source it to the original radius.

Are Victorian windows really worth keeping?

They are usually the single most character-defining element of the facade, and the joinery is better than anything mass-produced today. Restored and weatherstripped, paired with a storm window, they also perform respectably — there is rarely a good argument for removing them.
