Just finally completed all the windows in our home. We did them on 3 trips due to the cost and we…read moredidn't want to take a loan out. Windows cost a lot no matter where you go. It takes about 6-8 weeks once you order. We had problems with our install on 2 of the trips. The second install the guy left caulk in 2 spots on our hardwood floor. We never called about this because we are planning to resand them. This is very careless on his part because he did have tarps down. The 3rd install the guy who put one of the octagons in never leveled the window. So as they were ready to leave and my husband checked the work it was obviously off center without even placing a level. The guy fixed it before he left. Now that the work is done, we are happy. Windows are beautiful. Just make sure to check everything over before they leave.

Update January 2026:…read more Called once again for a simple draft issue. Immediately they start talking about replacing all of the windows. The problem is simply the 3/16" fur weatherstrips becoming matted from use over the years and needing to be replaced. They just slide out and you insert a new strip. The strips are literally $10 for 25 feet or $30 for 100 feet if you buy in bulk...Feldco wants to charge thousands of dollars to replace entire windows when the weatherstripping on the entire floor (7 windows) would be under $60 and take maybe an hour to do. Record keeping also may not be not up to par as they seem to be missing records for the building. They are beyond greedy and prey on customer's ignorance. Avoid them like the plague.

First I would like to thank Peter Metcalif my product…read morespecialist who came to my home to help me replace an old side door. Peter explained everything and gave me all the details on install and product. Today, Daniel & Idalia my door installers came to install my old side door as well as a storm door. I am absolutely amazed at the quality of work!! The dream team amazing perfection. My side door was no easy install either with the custom dimension. Everyone was so polite and kind. God Bless You! I want to say I think it was 2011 or 2014 Feldco also replaced all my windows and sliding glass door, and they still look brand new great quality. I will be calling you back for my garage door. Thabk you again! Kelley

It's a builders grade glass door, so the lower quality of the door made it more difficult to repair. All of the other companies we obtained bids from said it couldn't be repaired and quoted 2500 to 3000 for a replacement. Peter came over on a Sunday morning and repaired it expertly. Our front window had a broken sash and required a complete replacement. The replacement cost Peter quoted was a reasonable price and he took out the old damaged window and replaced it with a new one, spending time caulking and finishing the job. Peter responded quickly and provided a quote before beginning the job. I highly recommend Pat Builders.

The salesman was thorough and complete. I chose all the upgrades because I wanted the best possible door and frame and it cost over $2K. It was when the install came is where problems started. The old door was ripped out quickly and completely. Good. The installer then started to work off of a flipped over garbage can. I let him use my workbench. I checked in every now and then and towards the end, I came out and he was drilling into the latch with a large drill bit. I stopped him and even bought out my Dremel for him to use but he wouldn't saying he had to use his own tools. Long story short, he screwed up the height of the latch inset, drilled out all the wood and it still wouldn't lock correctly, daylight was coming in the garage with the door closed in the latch area, the frame was completely drilled out and lost strength. I ended up having to shave the latch inset and redo the wood behind it for added strength. It is still not "right" but I got it to work. Nobody ever followed up to see if I was happy. Not the salesman, not the office, nobody. I felt after paying over $2K, I should have gotten a better install and a follow up. Giving three stars for the quality of the door which is very solid and great security for the garage, but the install was not so great and there was zero follow up. Its been about two years now.

I had a single entry back door and wanted to convert to a sliding door out to patio. My house is a brick home, and their installers were able to make the opening to fit a sliding door. They were able to match the door stain to my windows and everything looks perfect! The installers went above and beyond to make sure I was satisfied. They even went as far as to building temporary steps to lead to my outside patio. I will most definitely recommend them for your home window and door project!

With supply…read moreissues, the doors didn't come in until March 16, 2023.I noticed the storm door & hardware is wrong. Main door only had a keypad deadbolt & the storm door was the wrong one! They needed to reorder the storm door, the hardware & I had to deal with the deadbolt issue for a month. Also found the Main door wasnt flush/sealed with light coming through. I called them & told they would look into when they return w/ storm door. April 25, 2023-The storm door was installed, switched out hardware,one was still incorrect but forget it! The Installer stated he didn't like how 1st installer did the entry door, it was too loose. So he adjusted it & gave it a tighter close. Told me that I would have to push hard or pull hard on the door to latch for a few weeks until the seal around the frame forms to the pressure. Woohoo thought that was the end. NOPE! I had called them back, about a week later, new storm door wasnt shutting & hitting the frame due to expanding in sun. I also noticed the entry plate on door frame was also unstable & bent forward when stepped on. Like there was nothing under to support it. So I called them about that & was informed they would look into it when the come adjust my storm door. Thats not all folks! May 12,2023 I noticed a manufacturing defect in the panels of my main entry door. The door wasn't completely sealed together & looked like the panels were separating from each other & cut with a dull blade. May 25, 2023-They came back out,Fixed the sagging entry plate.Took pictures of the defective door & had to order another door & take about 4 months to come in! Two weeks later I also notice a crack in my door frame by the hardware & a random screw loosly between. I called it in. They stated that they will be able to fix it all when the door comes in. Its been 5 months & my door still didn't shut unless slammed to latch. My son would leave for school & the door wouldn't be fully shut. I'd come home to a door that could be tapped open because it wasn't catching the latch. OCTOBER 27,2023! (1 year since purchase) I called them for an update as it's been 5 months. They couldn't find my delivery papers so, they had the warehouse search if it was even there. They called me back stating it's never been delivered. So they stated it will be here on a Monday 10/30/2023 and install it 1st thing 9am Friday morning. I had to call off work just to get it taken care of. I asked Brandy about the frame issues as well because I don't want them showing up just expecting to switch out my door. They need to replace the frame again. She had to call the boss & discuss the issues to find a solution & call me back. November 3,2023 Friday It's 9:40am & no one has shown up. I called them because my daughter had a doctor's appointment at 12pm. I was told the guy was still at another location but he's finishing up & will be there shortly. I thought I was the 1st thing?! Around 10:30ish I call again. He's still at the first job! I had no show!!!! So I told her to forget it as I needed to get my daughter to her appointment. They show up January 5, 2024 w/ new frame & door. Frame is damaged! After inspecting entry door, I was asked to store the door at my home to minimize possibility of getting damaged. Appointment was set up week of January 29th. Called me the day before the appointment to reschedule. I was LIVID! BRANDY gave me attitude. I proceeded to tell her the time & money I've lost while paying off an incomplete door for 1.5 years! They showed up Saturday February 3rd (1 HOUR LATE) & it's still not finished. I'm missing a screw that was never screwed in on a hinge & a protective cover for exposed screws to the outer frame of storm door. Called & left Brandy a message that week requesting this. I was never called back. 12/7/2024 I'm hanging a wreath & the suction cup falls off the door panel & it took paint with it!!! I'm over it!! I've been paying off a $5299 bill since May of 2023!
