What We Offer

Exterior Drainage: The two most common types of exterior drainage are Exterior Drain Tile and French Drains. Exterior Drain Tile is installed along the perimeter of the home to guide water away from the foundation. French Drains are used in other areas to give pooling water a route away from the property. This is a popular option for those who experience issues such as a flooded backyard during heavy rain.

Exterior Sealing

Another effective exterior solution is Exterior Sealing. This is performed using drain tile, plastic, and tar to form a barrier to keep water from entering the basement and giving any water that collects at this barrier a route to escape. We are able to perform this repair with homes that are on a cement slab, commonly called Slab and Grade, so don’t hesitate to call BWM for your foundation as well. Our knowledgeable inspectors will be able to suggest the proper solution for your home and budget.

What Our Customers Say

William H was an amazing representative from BWM! He spent a lot of time giving me my estimate and making sure that I understood every aspect of the project. He explained everything to me very clearly, thoroughly, and in simplest terms and made sure to check if I had any questions throughout the process. He was very understanding of my concerns, and he assured me that he would be available throughout the span of the project if I had any concerns or ran into any issues at all.

March 26, 2026 I had inspection, by BWM, for cracks in foundation walls. Senior Inspector William H. was able to give two separate quotes fixing individual cracks or install perimeter french drain system. Bill was able to answer all my questions. His knowledge and expertise made it easy for me to understand the job that I needed to have completed.
Thanks-rst, Livonia, Michigan
