"I live in a house that is over 100 years old with a stone foundation that also forms the basement walls. The old mortar between the stones had deteriorated over the years to the point that water would seep in in multiple places along the perimeter of the basement wall. This seepage basically occurred after every rain, and I always needed to move objects stored in the basement away from the perimeter for fear that they would be water damaged. I actually wasn’t very confident that the seepage problem could be fixed, but I finally decided to contact several basement contractors to determine if there was anyway to waterproof the basement. I ultimately decided to hire Basement Gurus because Mike (initial company contact) sold me on the idea and that their workers were the best in the business. Well, it’s been seven weeks since the basement work was completed, and even though we’ve had a couple of nor’easters with heavy rain blow through the area, the basement has been bone dry; the basement work has been a resounding success! I take my hat off to all the good folks at Basement Gurus, in particular Mark, Dylan, Lenny and the other members of the team that worked hard to waterproof my basement. In sum, I would highly recommend to other homeowners who may be experiencing similar basemen water seepage problems to consider Basement Gurus as their “go-to” company."

My family and I have nothing but fantastic things to say about Mark and Judy.  They both were easily accessible by phone or email, professional, and patient regarding the numerous questions I frequently put to them.  Mark was very straightforward with me, and worked hard to overcome the obstacles that popped up.  Bottom line- I was able to obtain a loan at a good fixed rate, and am very satisfied.  I would (and do) recommend them to my friends.

"We are so happy with the work of WilMarc Construction- we have had them do two major home remodels for us- both times, Willie came out and listened to our ideas and what we had in mind and then gave thoughts of his own (which were always better than ours) and the results were both beautiful and reasonable. Our first project was redoing a kitchen and we had thought an extension would be best and he came up with a more economical solution to combine a couple of rooms, change windows and location of the bathroom. He always did what he said he was going to do and didn't overcharge. Our last project was just finished- installing hardwood floors and redoing two upstairs bathrooms. When we started pricing out flooring at a couple of flooring places, we realized it would be better to ask Willie his opinion and get an estimate and we ended up doing two bathrooms as well as the floors and replacing the stairs--all things that needed to be done for a reasonable cost. I would recommend asking Willie his opinion on what your plan is and your choices, he has done a lot of projects and sees the final project so with regards to durability and beauty he can offer really helpful suggestions with material."

"I recently had the pleasure of working with Adam to have epoxy floors installed in my home, and I couldn't be happier with the results. From start to finish, he demonstrated professionalism, attention to detail, and a genuine passion for his craft. The floors look absolutely stunning—smooth, glossy, and perfectly even. The transformation in my space is incredible, making it not only more functional but also incredibly stylish. He took the time to explain the process, answer all my questions, and ensure that every detail was executed flawlessly. If you're considering epoxy flooring, look no further. Adam’s expertise and dedication to quality are second to none. I highly recommend him for any epoxy flooring needs—you won't be disappointed!"

Basement Remodel questions, answered by experts

The most challenging part of finishing a basement is addressing moisture control. Basement waterproofing is an essential task that requires a professional’s skills and knowledge. If you don’t properly waterproof your finished basement, it’ll be vulnerable to dampness, water damage, and mold growth. Ensuring proper insulation and ventilation to combat these issues while meeting building codes adds complexity to your remodeling project.

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Joists and beams are both part of the flooring system above your basement, with the beams spanning the length of your home and getting support from vertical posts underneath, and joists usually spanning half the width of your home with no support posts underneath. The floor joists provide even support to the subflooring and flooring above, and they distribute that load to the beams. The beams then distribute that load down through the support posts to the foundation.

Adding a bathroom to your basement can increase your home value since homes with multiple bathrooms sell for more. The return on investment (ROI) for a basement bathroom is 50% to 75%. The actual return varies with your home and location. Adding a half bath to your home increases the value by 2.9% while finishing a basement increases the home value by 6.6%.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.
