"We hired Joe and his team to handle our primary bathroom remodel and are very pleased only a few days into the work. While our bathroom is on the small side, in order to get what we want, it requires complete demolition and all appropriate re-configuration so it is a substantial project. In our initial consultation, Joe provided great space-efficient ideas and helpful suggestions for where to shop for the items we'd need. He has been extremely communicative and responsive which we greatly appreciate, as that can be hard to come by. So far his team has been quick and efficient and is meeting our expectations in terms of the daily schedule and progress. Attached is a before picture of one side of the bathroom, as well as a mid-way pic after the demolition. We will update this with a completion photo in just a few weeks!"

Basement Waterproofing questions, answered by experts

Typically, waterproofing a basement should last up to 10 years. However, it’s worth noting that with proper maintenance and depending on the waterproofing method and installation quality, you can probably squeeze another decade out of it.

The best way to waterproof a basement is to install a properly functioning gutter system and a French drain around the outside of the foundation. The best solution for your home could involve other waterproofing methods that resolve the problem unique to your situation. Depending on your soil type, climate, and other factors, that could include sealing, landscape alteration, interior drainage systems, and more.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
