Testimonials

What Our Clients Say

Client reviews; what some of our customers have said:

"I contacted Dowling and Sons to provide some upgrades to my existing windows and doors. D.J. Dowling was quick to respond and recommended that I recap several windows that had been done improperly, causing the unsightly gaps and allowing water to get behind the existing cap. While there, DJ also replaced my door insulation strips an realigned the doors and locks. I couldn't be more happy with the completed work, the communication and the fair price. I would definitely recommend Dowling and Sons for your windows and door needs."

Jack S

The railings on the front of my house became very unsafe, I had Dowling and Sons do my windows which were amazing, I contacted them for my railings. The job was done very fast and at a very reasonable cost, I highly recommend them for any contracting need!, they are the only company I will ever use again”

“DJ was professional, fairly priced, organized and timely! He has many years of experience in the business and it shows! He did a Fantastic job and we will be having him replace some basement windows this fall also! Friendliest guy you will meet! Support small business and you get the extra customer service that you can’t depend on from a big box store... and DJ did not disappoint! Thanks again:)”
