They were contracted to replace all of the siding and the wood on my house with Hardy Board. We have a large 2 story house. They came and gave and... gave a very reasonable estimate. They had the siding made to our color choice and took 2 weeks to install it. They did an incredible job and cleaned up spectacularly. I could not have been more pleased. It was a good thing that I had the siding replaced in February as in August some idiot set fire to my hose. The siding blackened but did not burn. Saved my home. They Aldi did the replacement on the blackened siding. Again what a pleasure to deal with such a professional company. They get too marks across the board.

It gives us great pleasure to inform you that we are most satisfied with the quality of your product and services received from your two staff, Howard and Butch, who... have replaced all glass windows and doors in our home in Denton over 5 days. Howard and Butch personify utter professionalism: always reliable and punctual, wear face masks consistently (most appreciated during this pandemic season), seek client input when unsure, very attentive to details, careful and timely removal of installation trash, utterly responsible and dependable throughout installation. The final fit and finish was absolutely perfect! These two men from Brennan Enterprise personify the very high level of work ethic and professionalism of your superior products and services. (You should consider giving Howard and Butch a pay raise!) By the way, you have our permission to use this feedback to publicize Brennan products and services! .

I encourage all homeowners to seek out estimates AND options from Home Depot and Lowe's before contacting Brennan. Watch how the the competition "treats" you... then, you will without a... doubt choose Brennan. We have been living with OEM F&J Front (Double) Door and rear single pane glass sliding back door with 3 panels that were deteriorating over the years and completely awful at sealing out the cold/hot outdoors. We wasted $50.00 paying for an estimate from Home Depot to hear that of the 100s of front doors they had in stock, our front doors would only fit "1" door they had in stock, to which we declined because it was hideous. We instantly lost our $50.00 and they lost our business...forever. I called Brennan and arranged a "free" estimate expecting to be pushed into a 'sell' job. Everything I experienced with them was completely professional, yet it felt sooo personal. Our estimator let us know that there was no such things as only 1 model to choose from. He took measurements and said that any door in his book was available. He brought out a computer generated program and we designed the doors, the glass features, the thickness of the door, the hinges, the door handles, the paint... OMG! I have NEVER been this at ease with anything I've ever purchased. The installers were beyond the best I've seen: they were on time, well presentable, courteous, and very knowledgeable. While installing our back sliding triple pane doors, he pointed out that the 'previous' door installers (probably Fox n Jacobs) did a shoddy work around whereas they installed an additional temporary platform slab because they had done some jerry-rigging to extend the door outward to save on interior space. By doing so, our installer identified the actual sliding door bottom track was actually mounted only 1" of the 3" base onto the slab. He removed all the shoddy work, and inset the door in the correct spacing so that the full bottom track of the new doors is completely on the slab -- no free floating over hang. I have had the absolute best customer service experience with this company and highly encourage anyone looking to replace their doors to use their service. Thank you for all you have done in our home and thank you for installing 2weeks before our original install date.
