"Tim was prompt, professional & listened to my questions and answered my questions patiently. His knowledge of materials and costs helped me get this project done well & in my spending plan too. My decks are now in great shape, look better than they have for some time, since Dominion’s very skilled crew replaced worn decking and stained the deck and railings. Our family can really enjoy this special part of our home for years to come now!"

"Very satisfied with Pro Line construction from start to finish.Tony came to measure and do a full and detailed presentation on what the new roof would entail. They are platinum installers for Owens Corning - which means they receive extra training for the latest materials in the business. Unfortunately , because of the fickleness of weather they couldn?t come as quickly as hoped. However , once they came they were amazing. I had 7 men ripping off my two layer roof and garage roof - and they looked like Santa?s helpers. The dumpster filled and materials were stacked all over the lawn and they never stopped working. The project manager stopped by several times a day and got on the roof to monitor progress. By the end of the second day the job was done. They didn?t leave until 7 pm and after blowing clean my deck and lawn. It was spotless. Awesome job well done"

"I hired Trinium Home Improvement for a deck repair. Mike was highly professional during the whole process, keeping us informed with all the details. The job was done within 3 days, they cleaned after themselves and our deck looks as good as new. I would highly recommend them and would definitely hire them again."
