"I met Mike, the owner of BMO Kitchen and Bath, and his team 8 years ago when he was doing a kitchen and bath remodel at my daughters house. We were all very happy with the work they did and decided to hire Mike and the BMO team for a full remodel of our home. This included remodeling the kitchen and 3 bathrooms, installing new cabinets, new plumbing new lighting and new flooring throughout most of our house. When we could not find cabinets to fit, Mike built beautiful cabinets himself. 7 years have passed since this remodel was done and everything Mike and BMO did still works great and looks great. We found Mike to be very honest, knowledgeable, reliable and easy to work with. He respected our opinion and was always available to give us his thoughts on how to improve our project and what products to use. We have been so please with Mike and the BMO team that we have used them for all construction and repair jobs since that time. We have also happily recommended Mike and the BMO Kitchen and Bath team to all our family and friends. They are very knowledgeable, very professional and a pleasure to work with."

Basement Remodel questions, answered by experts

Yes, it is possible to turn a regular basement into a walkout basement. Doing so involves excavating the land around at least one side of your basement foundation, installing retaining walls to create a permanent below-grade area outside your home, and then cutting into the foundation to install an exterior door that leads out to the new space. This is an expensive and time-consuming project, but it can add a lot of value and utility to your home.

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.

You can paint your ceiling or install a drywall ceiling if the ceiling is unfinished, as they take up less headroom than drop ceilings. 

If there are pipes in the way of ceiling installation, you can do one of two things: reroute the pipes or adjust the installation to fit, which will cost extra.

Generally, a wall can bow up to 30% of its thickness, or around 2.5 inches for an 8-inch-thick structure, before it becomes an urgent situation. If your basement wall bows more than 1 inch, it's time to have a basement inspection to determine if a repair is necessary, depending on the soil conditions and structural specifics. Walls nearing 4 inches of bowing will require significant repairs. More than 6 inches of bowing usually means the wall will need replacing.

Assuming you are going for a full remodel for an average-sized basement with a reputable contractor, the process can take up to two weeks or more. Remember that basements have many stairs and often difficult access—it’s not like working in the entryway. The shuttling of materials, increased need for ventilation and safety precautions, and making sure everything can be removed through a doorway all increase time and cost.
