I'm giving 2 stars rather than 1 because the finished product appears to be fine. Not what I…read morewanted, but it is what it is at this point. The ProVia Endure windows are functioning well, and the lifetime warranty provides some reassurance, though that confidence was significantly eroded by the process of getting here. A 1-star rating would be justified based on the experience alone.
I hired Tacheny Exteriors in June 2025 to install three ProVia Endure casement window sets in my home. The project involved creating new rough openings, headers, and framing. The original contract was $15,200. Electrical work was not in the bid. Once walls were opened, wiring needed to be relocated, adding $1,458. This can happen with older homes and is worth knowing going in. If you're having new openings cut, it may be advisable to have your own electrician on standby. In my case, I had no choice but to accept the price given since the walls were open and the project needed to keep moving.
Two of three windows were installed approximately 11 inches from the agreed placement. The basement window was also misaligned by 4 inches horizontally and 1 inch vertically. Tacheny initially acknowledged these errors in writing and offered to move the windows. After key staff left the company, that acknowledgment was walked back, and I was told I should have drawn diagrams on the wall to prevent the error. The project consultant, installer, and production manager all left during my project.
The building permit was filed incorrectly as a replacement rather than a new opening, causing a required framing inspection to be missed. Tacheny was notified by the city in July 2025 to correct it, but the inspection was never called in. When I raised this, I was told the error was the city's fault and that most cities no longer require mid-construction inspections. I verified both claims with the city inspector and neither was accurate. The inspector accepted photos but noted the gap in the final report and that a vapor barrier was not installed on the living room header. The permit was also filed at approximately $10,100 despite the contract being $15,200.
The NFRC stickers on the installed windows did not match the ProVia spec sheets from contract signing, showing Southern climate ratings instead of North-Central with significantly different air infiltration numbers. ProVia would not provide formal written confirmation, so I obtained a signed letter from Tacheny confirming the correct windows were installed. This might not have been an issue at all, but my trust was completely undermined by this point.
Communication was a consistent challenge with extended gaps in responses and claims of communications I never received. Information from Tacheny was sometimes inaccurate and had to be corrected after I verified details with the city inspector.
The project required me hiring a lawyer and a negotiated $5,000 settlement adjustment. The initial invoice labeled this a "Goodwill Discount," mischaracterizing the adjustment, and had to be corrected. Contract to final payment took nine months.
I want to note that the issues I experienced, including communication failures, installation errors, blame-shifting to the customer, permit and inspection problems, and extended project timelines, appear to be consistent with experiences described by other reviewers on both Google and the BBB. Potential customers researching Tacheny should also be aware that there are two separate Tacheny Exteriors listings on the BBB, one in Minnesota and one in Arizona, with the same logo. Make sure you are reading reviews for the correct location.
The windows work fine. The challenges were in project management, communication, installation accuracy, and permits. Document everything in writing, verify permit claims with your city, and be prepared to manage the project yourself.
