"I had 4 companies come out, 2 of them stating I needed a sump pump without even looking outside, or listening to other solutions I had from from other contractors. I HIGHLIGHLY recommend Mastercraft Waterproofing They told me that I absolutely did NOT need a sump pump and it was an issue with the sealing on the outside of the chimney. Water was coming through one of the seams. This was the only company who looked inside and outside on my property. Their work has a lifetime guarantee for what I had done, and saved me $1,000. Tom and Rob are the owners and came out for the quote, and were the ones who did the work. Personable, professional, reliable and cannot recommend them enough. They sent a follow up email for additional recommendations long term, with pictures of the project from start to finish. Please call them if you have water in your basement instead of these large companies who will tell you that you have a huge pool of water surrounding your house. Mastercraft Waterproofing does it all and will be able to help!"

"They advice, and had all our questions answered on sensible and affordable options. Very knowledgeable, prompt, polite, efficient, and thorough team! We are happy with their waterproofing services in our basement (fast sump pump and a grate trench with a discharge line that goes 15 feet to the outside bubbler) as well as crawl space shield installed under our addition. It works well, and Pioneer checked a month later and a year after for inspection and cleaning. A+ work and workers."

"I was impressed with his knowledge and professionalism. He installed a French drain system with a vapor barrier on the walls. He prepped the area to protect our belongings, made sure everything was cleaned up after the end of each day, and provided exceptional service and quality. I would highly recommend him!"

"Amed and Antonio did a wonderful job installing the pump system. What was going to be done was explained and I could observe if I wanted to. Steve who accessed the job was excellent. I was very happy with Dryzone and would gladly use them again if needed."

"Corey C of Basement Technologies performed our yearly maintenance inspection on our Basement Technologies sump pump, and did a fine job. He arrived within the expected timeframe, and provided us a detailed checklist of all items inspected. He also reviewed the operation of the alarm systems with us. He was friendly and courteous throughout."

"We booked AQRS for opening our pool at the start of the season. We had a few bumps due to our own equipment but aquatic resources sourced the parts and rectified the issue promptly. We booked with them again for our pool closing and they also supplied and installed a new child safety cover for our pool. Very happy with their services and have already booked our pool opening with them for the next season."

Basement Waterproofing FAQs, answered by experts

A crawl space can be as little as 42 inches below the grade of your house, but this is not always recommended in flood-prone areas. At a minimum, there must be at least 16 inches of clearance between the ground and the floor joists to access the space in an emergency.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

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.
