"Mark and his team at Haven Home builders was excellent. My basement was flooded and they remodeled it from the studs. They were very professional showing up on time every day and attentive to every detail. When asked, Mark provided great suggestions. His team is trustworthy and I would hire them again for any future home remodeling needs."

"Started with a bathroom overhaul, then a kitchen remodel. Meticulous and precise in his work. Very patient with our changes! Very knowledgeable, and we have 3 small children whom we were always comfortable having STHD around them. Answered all of our questions. Explained things thoroughly. Design team has amazing vision! Lastly, never once did we feel insecure leaving our home while SRHD was there working. So pleased that we had SRHD come back and remodel our basement as well!"

"TJ Kustumz has my very highest recommendation. So far, they have done two jobs for us: a medium size kitchen remodel (tile backsplash, electrical, some cabinet work, install microwave); and a complete replacement of a master bath shower, which was a pretty large project. Tim, Rick and Nick were very honest and professional -- careful in their planning, estimates, and especially in their work. The quality of the work was superb, and Tim was a great creative help as well -- he has a very good eye for design, and suggested many elements of the work that made it far nicer than we originally envisioned. Rick is also very good at creative design. I also want to mention that the entire team was excellent at problem solving -- nothing ever goes exactly as planned; there are always surprises, but nothing fazed these guys, or even slowed them down. Importantly, the tile work was just outstanding; everything was done with precision and attention to detail. Finally, I must note that Tim, Rick and Nick were a pleasure to work with. They are nice people. We are making a list and checking it twice for future projects with them. Richard T. McCoy, Wexford, PA"

"The HomePro Remodelers, with their exceptional skills, helped make our project a huge success. They took extraordinary effort in cleaning up and were very considerate of our surroundings. Since our back porch enclosure has added so much to our lives, we are considering having our front porch also enclosed."

"Conrad and his team are very professional and affable. We enjoyed working with them a lot. They are very careful of cleaning as well as noise and dust control as we have a new-born baby at home. They also have good recommendations of material supplies that we were able to own a very modern-style looking kitchen in the end. All experiences are positive!"

Basement Remodel FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

A finished basement must have a heat and electrical supply with an entrance that meets building code requirements, such as a stairwell to the home's main living space. It often must include finished walls, ceilings, and floors. If the finished basement includes a bedroom, it should have a heat source, an egress window, and a closet.

Remodeling, as opposed to finishing, means altering an already finished basement by adding a bathroom, bedroom, or living area.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

Yes, you can add a door to your basement—it might even be required, depending on building codes in your area and whether or not you’re using the basement as a bedroom. A basement contractor can give you some advice on installation and help you add a door to your basement.

Costs are guided by renovation scope, materials chosen, project duration, structural needs, and labor. Prioritizing tasks prevents unforeseen expenses.
