Get matched with top addition to existing structure builders in Hummelstown, PA

"Would highly recommend Jason and Blue Mountain. We recently used him for a master bedroom and bathroom remodel as well as renovations to our screened in porch. Jason was responsive and communicated with us every step of the way. He met the timeline and deadlines that were set for our projects. Jason and his skilled employees were friendly, courteous and a pleasure to have in our home. Their work was meticulous and they cleaned up every day before leaving our home. We are thrilled with our upgrades and have future projects planned with Jason and Blue Mountain Building."

"Transformed my outdated kitchen with minimal storage into a modernly designed and functional kitchen! It turned out absolutely beautiful and I will be hiring again for my master bath renovation in the near future. Highly recommend for all your home improvement and remodeling needs!"

"Hired them to hang sheet rock for a renovation. The end result was great and the workers were nice. Only will mention that they didn't seem set up to do work in existing homes. Showed up on a wet day without any floor protection for our hardwood floors I specifically pointed out during the estimate needed to be protected. Would use them again though."

"My husband and I needed to have our bathroom and kitchen remodeled. We solicited quotes from 3 contractors and selected Dougherty to do the work. Since my husband and I are both retired we had plenty of interaction with the Dougherty staff and their subcontractors. We were very impressed with their professionalism and the quality of their work. I love my new kitchen and bathroom! Yes, there were minor problems, but we have an old house and went into the project knowing they might uncover some things. Their staff collaborated with us when any issues arose so that we could reach a workable solution. The final cost was within 10% of the original bid, mostly due to cabinet upgrades. We have since contracted separately with three of the Dougherty subs, one for routine HVAC maintenance and the others for a large room that needed drywall repair and painting. I would hire Dougherty again without hesitation."

"Both the drywall crew and the finish pro arrived on time each day and worked quickly and efficiently. I received quality work for a fair price. The employees were a pleasure to interact with."

"We had a deck/porch, and front door replacement.Work was done in good time. We like it and are very happy. Some of our neighbors complemented that it looks good. I recommend this company to anyone who needs work done."

"Blue Mountain Building and Remodeling, Inc. was extremely professional and did an excellent job on our basement remodel. Jason is a stand-up guy and takes pride in the quality of work his company does. It is rare to see a contractor that is as excited as the customer to see the finished result, which Jason was. The project started on the date he said it would and actually finished 1 week early! The guy’s Jason has working for him are just as professional and take great care in doing fantastic work. They arrived everyday on time and completely cleaned the area at the end of each day, before leaving. There were several times when they would come and get us to review a possible change and make some suggestions when they felt necessary, which really helped us along the way. These are the extras that mean so much when completing a big home project. We will definitely hire Blue Mountain for future projects and wouldn't hesitate to recommend them for any home project, regardless of size and scope."
