There are some high pressure companies around but Sullivans is NOT one of them. He came to the house, saw what we wanted and emailed us an estimate, which we accepted. He ordered the doors for us, called when they came in and he and his helper spent two days installing them. They are good people and they know what they are doing. Now we know why they get so many good reviews on Angi. We may use them again.

Tony and his team showed up on time and did a nice job installing my sliding door. They were neat and professional and everything looks great with only concern being that the door requires too much effort to slide but they said it should loosen up and would adjust if it doesn’t.

I needed my exterior hatchway replaced along with a rebuild of the stairs going to my cellar as the original wood was completely rotted out. The wooden door entering the cellar didn't need replacing, but all new hardware was installed. The trex deck over the hatchway was fixed and new hardware was installed. Tony, his son and a helper were excellent in every way. The project was top notch and I couldn't be more pleased. I would recommend A. H. Sullivan, LLC to anyone. They offer quality work at fair prices.

Tony called right after I sign up on Angi. Made an appointment with him within a few days. Showed up on time. He called me on a Friday to tell me that he wanted to start the installs on Wednesday. Said that it would take him +/- 1 1/2 days. That is just what it took him to complete the job. I am going to have him do some more work in the spring. Would recommend him for sure!! Thanks Tony!!

Being a new homeowner and needing contractors for upgrades for the First time I feel fortunate to have found AH Sullivan . He took the time to listen to my overall vision and offer me budget friendly choices without trying to upsell the most expensive stuff ,all the while explaining to be the benefits of each level of materials . After settling on styles and price I was given a time frame that I could expect the work to be done !!! I was amazing when I received a call ahead of schedule saying materials were in early!!!! The job took exactly as long as he said it would and was very neat and clean . Add to thay they had to work around my busy house between pets,kids and other contractors. Truly a perfect experience . Job was done right First time and no issues at all . I can't wait to find more work for AH Sullivan
