We initially hired Mark to do some some minor interior work on the upstairs unit of a duplex that we purchased for a rental. After evaluating the original project further, he made us aware of a lot of work the previous owner had done that was not done to code and in fact posed safety problems. We gained a great deal of confidence in Mark's work and opinions and in the end, we hired him to completely redo most of the upstairs and all of the downstairs unit. He took the spaces down to the studs, created new walls, installed an extensive fire and sound barrier between the two units, installed all new sheetrock, completely replaced all electrical, plumbing, HVAC, windows, doors. He laid tile in the bathrooms and helped design and install new kitchens. In addition, he installed all new flooring in both units including woodwork, trim and painted the entire space. On the outside, he did minor landscaping, laid a gravel driveway and subsequent walkway to the lower unit, and completely rebuilt a two story deck off the back of both units thereby increasing the outdoor living space for our future tenants. The decks alone were a feat of engineering - this was not just my opinion but the opinion of the building inspector. Through all of it, Mark was a pleasure to work with and always sensitive to our ever growing budget as we made change after change. He allowed us to be involved as much or as little as we wanted in order to safe money on the project. He even came up with a clever way of creating a laundry unit in both units which greatly increased the appeal of both units. It might bear mentioning that both units rented right away after all the work was completed and we have had no complaints from our new tenants. We have 100% confidence in the work that he does and have recently hired him to do some remodeling on our own home. I don't think there is anything that he and his crew cannot do to the highest professional standard.
