 Trustindex verifies that the original source of the review is Google. For the last two years, I have been remodeling a home and property in Oregon City.  We’ve taken it all the way down to the studs and have rebuilt everything along with addition, additions, and new spaces.  As a non-construction professional I’ve noted my interactions with various contractors. And unfortunately, I’m here to report that a lot of them are just not good Except for Fonzi.

I appreciate Fonzi and his workers Because they do as they say, and they say they do.  Are excellent at communication and are willing to work with you when issues come up because they always come up.  It feels more like a partnership.

As a business owner, one of the things that I’ve always told my employees is, it’s not the mistake. It’s how we react to the mistake that the customers remember.   Like any project we had a couple mistakes, but the way in which Fonzi and his team owned it, fixed, and took care of. It is really a high mark for me.

I’ve had him do my siding and windows for the house.  Which I was so impressed with, I awarded him a siding project for my shop, And also had him build my deck!

If you’re looking for a good contractor, no excellent contractor. Run to Fonzi don’t walk.  He’ll get booked up fast because he’s worth it.

Julio from his team was an absolute rockstar in navigating a big water damage insurance claim we had to go through, the whole team is professional and just really good people. We will definitely be using Fonzi Construction again, and highly recommend you give them a call before settling for anyone else!

It was a great price and beyond that it was exceptional service. He has amazing communication, he is kind, he does fantastic work AND has the absolute best team working for him. Everyone was fantastic! Renovations can be stressful but Fonzie and his team made it a wonderful experience!

 Trustindex verifies that the original source of the review is Google. I rarely write reviews but felt compelled after a sucessfull interior and exterior remodel.

Fonz handled a full interior and exterior remodel, including new siding, window installation, and converting an unused space into a beautiful and functional part of my home.

The quality of work was excellent, the crew was professional and reliable, and
Fonzie’s communication was outstanding from start to finish.

I've dealt with other contractors in the past and the difference was night and day. Fonz Construction has earned my trust and will be the only contractor I use going forward. If you’re looking for a dependable, high quality construction company, look no further!

 Trustindex verifies that the original source of the review is Google. Fona Construction was referred to me by a colleague in the construction industry for a replacement of a broken window. During the site visit I found out they also did siding work, which my HOA was in the process of getting quotes for one side that needed siding replacement as well as adding 2 new transom windows on that side.
After obtaining three Quotes, Fonz Construction was awarded the work. Their workmanship was excellent and everything was finished beautifully and efficiently. I highly recommend Fonz Construction For their quality of work and the Integrity of the team-An exceptional combination that’s hard to find.

Frequently Asked Questions

Can you replace windows and install new siding at the same time in Lake Oswego?

Absolutely! We frequently combine window replacement and siding installation into one seamless project, saving you time, reducing disruption, and ensuring a perfectly finished exterior.

What types of siding do you install for Lake Oswego homes?

We install lap siding, Hardie board, and premium vinyl siding — all built to resist Oregon’s moisture, mold, and temperature fluctuations while giving your home a sharp, polished look.

How do I know if my siding needs to be replaced or just repaired?

If you’re seeing widespread warping, cracking, moisture intrusion, or persistent mold growth across multiple panels, a full replacement is likely more cost-effective than repeated repairs.

We install windows in all styles — modern, classic, custom, and standard — for both new construction and renovations, ensuring a perfect fit and finish tailored to your home’s aesthetic.

How long does a window replacement project typically take?

Most window replacement jobs are completed in one to two days depending on the number of windows. Our team handles everything from precise measurements to final sealing, with minimal disruption to your daily routine.
