They sell nice products. Spent over $2200 for a great front door & storm door. Told the salesmen that I would need 3 to 5 minutes to replace the 25 year old burglar alarm switch into new frame and said no problem. Almost needed a large mop to wipe up installers tears. Said u are holding me up. A few years later the fancy door pull handle on storm door broke so I went to their main showroom.

Girl said to wait a few minutes and lady owner would be there. Worthless clueless owner said that was not from them. Sent me over to S&H hardware store where they charged me 250% more then Amazon then made me show drivers license because I was charging something. They replaced 4 windows in my house a few years ago and were great. Great install including outside capping & caulking. Wiped down area & ran shop vac. Very clean. Would get them again.

I had Gallagher Brothers install 3 windows in the front of my house in Mayfair. The cost was reasonable because they completely capped all around the windows, which was a lot on my house. Although I knew there was a delay with ordering, I appreciated the fact they were available a month early. The guys came early, set up a good work space on the inside & outside of the house with tarps laid around the job site. They worked efficiently & quickly. They did an excellent job of cleaning up when they were done. I still need more windows & will call them again.

I had an estimate done for two doors. Called to schedule, and the owner reported that the estimate was incorrect and he had to come to do another. So he came and said he would have to review with his wife. Then they started to dodge my calls. I have called back multiple times and they keep "taking messages" and report that they will get back to me but never did. Extremely disappointed.

Gallagher Bros installed all my windows and my brothers windows. We both had a great experience. We had a manufacturer defect but the issue was handled promptly and efficiently. My family and I will be ordering doors in 2020.

I had a new front door installed in 2016 by Lowe's. Their subcontractors installed the original door in 30-minutes. It was never hung properly and repeated calls to the vendor resulted in more cut-rate subcontractors doing sloppy work. I called Gallagher's late last year and ordered a new door. No pressure applied. I had to wait for it to come from the manufacturer and it wasn't cheap.

Definitely worth every cent. Ron began the installation at 8.00am on a Saturday- to accommodate my work schedule- and continued non-stop until after 1.30pm.! It looks great and I have had no issues! Will last for years to come. Highly recommend.

I just got 5 windows installed at my house in Richboro. It took a little longer than expected but it was worth the wait. I am very happy. After the summer is over, i will be calling to get a new patio door.

We were having our kitchen remodeled (which used to be our living room many years ago. Our front window was two old double hung windows side by side and originally we had them changed into a picture window with two sliders on either side of the picture window. But it was time for a change when we started our major remodel.) we went from the picture window to a BEAUTIFUL Bay window with crank side opening windows. Gallagher Brothers made a roof over the new window that blended right in with our existing shingled roof.

Our kitchen contractor laid tiles on the sill to match our floor and walls because I put plants in my windows and I didn't want to worry about the water ruining any wood sills. It's perfect to wipe up spills and dirt and leftover glitter from holiday decorations too. We LOVE LOVE LOVE our window! Even on the sunniest hottest day, when I am at my sink, I don't feel like I'm getting overheated by the window.

And I haven't lost a plant yet from being scorched from the sun! I have orchids- air plants on my window sill. Everyone is HAPPY HAPPY HAPPY all the time. no matter what season! We are now ready to replace the rest of our windows in our house because we are updating each room. Gallagher Brothers are first on our list to call! We trust them and know their work!

And next year will be a new door! So if you want things done right, And you want to see some really hard working guys who know what they're doing AND are respectful and responsible, they come when they say they will be there and they clean up when they are done the job, then give Gallagher Brothers a call! You will NOT be disappointed! Also, while they were working, not one of the guys spoke to the other harshly nor did we hear any foul language while they worked.

They were laughing with each other (which was so nice to see and hear) It's good when you're having work done on your home and those doing the work are not coming stressed, angry or someone is barking orders and creating tension. This is the company you want to work for you!

Gallagher Bros. Did an amazing job on my windows through out my entire home. They worked so hard with me helping me and my husband decide what windows were the right fit and price for what we wanted. Everyone who we came in contact with From Gallagher Bros were so kind, patient, respectful, helpful, and extremely friendly. Would highly recommend them for anyone looking to get new windows installed. Anytime I had a question they were right there to answer me. Thanks Gallagher Bros. For an amazing job! You guys rock!

My husband and I used Gallagher Brothers multiple times on multiple houses for both windows and doors. We've always been satisfied with their work, customer service and the installers. Our most recent job was having 7 windows installed. they arrived on time at 8 am and installed the windows in three hours. they are timely and efficient, and I recommend them every chance I get!
