"When Mike came out to give me a quote, he told and told me he would get back to me in a week and could probably finish part of the work in the next two weeks and start the full remodel within a month. That was in January, and I'm writing this review at the end of March. I called him several times and finally caught up with him about a month ago, when he said he had had some family issues and would get back to me soon. But he never did. I spent time cleaning my house, speaking with him, writing him an email with all the details of my project, calling references, and waiting months for an answer. The very least he could have done was said he wasn't interested in the project."

Top Bros Construction & Remodeling Inc. is a family owned business by two brothers that love to create customers imaginations into realities. We as Top Bros Construction do all kind of interior remodeling in people's homes. From remodeling your bathrooms into master bathrooms or having the nicest kitchen you ever picture. We also install all hard surface floors starting from vinyl planks, laminate, vct tile, hardwood, engineer hardwood, ceramics. We refinishing and varnish hardwood floors as well as stairs and handrails. Were love to help our customers go thru the whole experience in a great matter of order and completion.

"⭐️⭐️⭐️⭐️⭐️ Absolutely Stunning Refinish – Highly Recommend! I couldn't be happier with the way our hardwood floors turned out! We had some old, torn-up floors that honestly looked like they were beyond saving—but the transformation is unbelievable. After the refinishing, they look like brand new floors, absolutely gorgeous, with a smooth, rich finish that completely elevates the look of our home. Not only was the quality of the work exceptional, but the price was also more than fair—especially considering the results. On top of that, they were incredibly professional: they showed up 15 minutes early, ready to work, and clearly take pride in what they do. It’s rare to find that kind of reliability and craftsmanship these days. If you're thinking about getting your hardwood floors redone, do it—and call these folks. I can't recommend them enough!"

Basement Remodel questions, answered by experts

The average cost of remodeling a basement is $30 to $75 per square foot. If your space is unfinished and looks like it may need more help, use the higher number when calculating your estimated basement remodeling costs. A good rule of thumb is to add an additional 20% to the top of your estimate to cover any “what if” situations.

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

Yes, you’ll use a macerator pump to install a basement bathroom without breaking concrete. The purpose of breaking into concrete is to connect the drain pipes to the main sewer line. But a macerator pump will bypass this step and break up solids until they are soft enough to pass through a discharge pipe. That pipe will carry the waste to the sewage line.

Yes, you can add a bathroom to an unfinished basement, but you’ll want to take proper precautions if doing so. As with any bathroom addition, you’ll need to make sure that it’s approved by local building authorities first. With unfinished basements, you especially need to keep an eye on proper ventilation practices.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.
