"I recently hired Coen Brothers Construction on a thorough bathroom renovation, and the outcome was outstanding. Their quality was excellent, and I am delighted with the final result. Their sub-contractors were also great and worked at the same high standards as the Coen Brothers. Although we faced some communication issues at the outset, we eventually worked through them, and it significantly improved throughout the project. They paid attention to detail; when my project manager saw me stripping the trim for reuse, they recommended buying new trim and a lumber yard to get it. And it makes a big difference having new trim with clean, sharp lines. Their tile work took longer than expected, but the miter cuts the trim cuts, and the finish is excellent. They were consistently punctual, respectful of my home, and very tidy - tidying up at the end of each day. While the project took longer than anticipated, the reasonable cost and the team's meticulous attention to detail compensated for it. Coen Brothers Construction also expertly handled all necessary permits and inspections, keeping me informed every step of the way. Overall, I am satisfied with their work and would hire them again for my next project."

"DiOrio B+D did a great job remodeling my kitchen: Seamlessly installed granite counter, sink, garbage disposal, dishwasher, high quality cabinets, Pergo laminate flooring, and electrical upgrades. Their offer was very reasonable. Derek + James are skilled artisans with years of experience. They both are diligent (nearly obsessive) about the quality of their work. If you seek a fast hack job that will fall apart in a year, they are not for you. They consistently stayed in touch with me throughout the project re. progress. They always want the best for the customer . I couldn't be more satisfied."

We discussed small changes to the layout (e.g., where the sink in the bathroom would be located) and everyone was very accommodating."

"They put a new roof on our house. They were efficient and did an excellent job cleaning up after completion. My only issue was the amount of shingles delivered to our house, even after the normal amount considered as a waste factor on the job was over 25% more than needed. They used 71 bundles to complete the job but had 94 bundles delivered. Then, they stated that we were never charged for 94 bundles. This made no sense to me. So, although they did a great job, I would recommend that any future customer get a detailed quote to include the amount of materials needed. Shame on me for not getting that when we got the quote. That was the only issue and the fact that the explanation received from them made no sense and was not very polite to me as the customer."

Basement Remodel questions, answered by experts

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.

When choosing materials for finishing basement walls, consider factors such as moisture resistance, durability, and fire resistance. Opt for materials specifically designed for basement environments, like moisture-resistant drywall or cement board. Insulation with vapor barriers can help regulate temperature and prevent condensation. Consider using mold-resistant paints or coatings. 

Research and consult with experts to select materials that are suitable for your specific basement conditions and intended use. Prioritize quality and compatibility to achieve long-lasting and aesthetically pleasing results.

Finishing your basement adds value to your home, providing an average return on investment (ROI) of around 75%. That means the typical basement refinishing costs of $32,000 will add an average of $24,000 to the value of your property. The value added to your home will depend on the price you pay to have the work completed, the area you live in, the quality of the work and building materials, and more.

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. 

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.
