Unfortunately, although I have used Dillman Brothers in the past, they were unprofessional and unresponsive this time. I contacted them several times and they repeatedly said they would send someone out to take pictures and give me an estimate to repair a screened porch/sun type room that they had originally installed. Although the office people were very polite and said repeatedly that a workman would respond, no one ever followed through. Repeated contacts since August of 2021, even one from my insurance agent, did not result in the promised response. Therefore, I must suggest that Dillman Brothers is unreliable and does not do what they say they are going to do. Unfortunate, but my experience.

Impeccable work installing a screened in porch for our home. It's so elegant and the work is tremendously detailed. Thank you Chad and crew! Service: General construction

A fascia and two soffits from our roof flew away on a windy day. I called Dillman Brothers who were the original contractors. They came and repaired it to my satisfaction and made it much stronger than before. Service: Roof repair

Dillman Brothers will rock your socks off! They are the nicest crew, do quick and professional work, and left my house, yard, deck, and garage more clean than they found it. They replaced my siding, gutters, downspouts, and facia. Added a new garage back door. And build cedar porch beams and bracing. They were wonderful to work with! Would recommend them 100x over. My neighbors were very impressed with the crew and the work they saw being done.

Recently had Dillman Brothers re-roof our house. Outstanding job, very competitive price. Everything was cleaned up post completion. They did our roof 18 years ago when we built the house. Their customer service for warranty is just number one and just straight up and very honest. It's why we had them come back to re-roof. Can't find a better company.

We highly recommended Dillman Brothers to anyone needing exterior work done. They were the best priced and were fast and efficient! We used them for a new roof, siding, windows, gutters, soffit and facia. They even put up the shutters we decided to get after we contracted them, installed the new porch lights we bought and hung our new mailbox. We couldn't be happier with the look of our house. It looks like a completely different house!
