"Very pleased with Mastercraft! Would highly recommend them to anyone who needs waterproofing. Our basement had a small foundation leak and Mastercraft found the exact area it was leaking from. Their work is impeccable they cleaned everything so well it was hard to tell they had to dig around the foundation. Very friendly and so nice to work with them. Thank you Mastercraft!"

"I highly recommend Start2Finish Waterproofing. Ed was wonderful to work with. He was timely, informative, and honest. There?s no inspection fee like most other companies. Their quote was very reasonable and has a lifetime warranty. Bob and the install crew were very efficient and left my basement in the same condition as when they came. For basement water issues this is the company to use!!"

"They did a great job. They were able to use a small pump to pump the waste water out before replacing the broken pump. The other company wanted us to pay for a pump truck costing $600 before giving the estimate."

Basement Waterproofing FAQs, answered by experts

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

While "dry" mode on your AC can help reduce humidity levels to some extent, it may not be as effective as a dedicated dehumidifier, especially in areas with extremely high humidity or larger spaces. Dehumidifiers are specifically designed to remove moisture from the air more efficiently, making them a better choice for tackling persistent humidity issues.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.

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.
