"I had a leaking roof and needed to get a new one quickly. Lo's Contracting had the best bid and time frame. I'm happy with the end result however it was a bit a fiasco. When putting on the roof there was a bad rainstorm at night and only the underlayment was down at that point. Water came in through almost every room in the house. As you can imagine, I was freaking out! However, I was able to get a hold of one of the workmen who called it in and everyone came out that night around 8pm in the dark and rain and put tarps over the entire house. They brought in huge de-humidifiers the next day and had them running for a few days which seemed to dry everything up. (Lo's Contracting paid for the extra electricity that the de-humidifiers used). They also replaced the insulation in the attic crawlspace at no cost. Three years later there was a leak around one of the nails and pipe collar on the roof, which reading up on does happen(not sure if it should happen after 3 years(that's why the B...but) Amadou was quick to check it out the same day I called and then sent someone as soon as their schedule allowed, a couple days. I appreciate them fitting me in to the schedule and responding so quickly and apologetically. They also cleaned my house after all was done. Amadou, the owner, and Marlon and his team were great to work with, friendly and fixed a couple little things that weren't on the bid at not cost. I would hire again - I'm just not doing anything during the rainiest months of the year again!"

"After interviewing several contractors for our kitchen and bathroom remodel, my husband and I felt immediately at ease with Matt. His professionalism and integrity shine through the moment you meet him. We initially bid out a modest bathroom and kitchen facelift in an old 1900's farmhouse. With his insight and resources, we were able to completely remodel both in addition to updates throughout the rest of our home (refinished hardwoods, paint, carpet, etc.). We had an aggressive timeline and he delivered on time and kept within our budget (aside from our requested change orders). Matt and his team of subcontractors surpassed our expectations and were lovely to work with. Matt was always available (never missed our calls) and patient with us throughout all the phases of our remodel. All whilst navigating effortlessly through the various COVID restrictions. We also had the pleasure of working with his lovely wife, Jacqui, who guided us through all the design elements. She made the overwhelming task of choosing paint, fixtures, faucets, tile, flooring etc., fun and fluid. She even showed up as we moved into our home equipped with homemade soup for lunch and helped us unpack! We are so grateful for the opportunity to work with Ziebart Construction and highly recommend them! We will be working with them again on future projects."

"I just want to say thank our project manager Max! He was on top of things and kept the project moving smoothly! I can’t express how stress free this remodel went compared to other remodels I’ve done. He communicates clearly, and followed up regularly. I’m just so impressed with how my new kitchen looks. From the blue prints to real life it’s exactly what I wanted and imagined. Thank you thank you!"

Basement Remodel FAQs, answered by experts

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.

Key trends include home gyms, theatre rooms, additional rooms (bedroom/office), and more, with personalized styles reflecting individual preferences.

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.

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%.

Framing a basement takes three to five days, on average, when completed by a professional, though it may take longer for a larger space. Keep in mind this doesn’t include the time to complete the design, obtain permits, and install the drywall on the framing. On average, fully finishing a basement takes an average of 45 days.
