"Dan was here this morning, showed him where water was leaking in over our slab and ruining the flooring in the master bedroom. He gave me the full range of possible remedies, from installing a eaves gutter on the roofline outside the bedroom to a full (very expensive) sealing of the entire exterior foundation. And actually recommended that we start with the gutter (which I can do myself) and then monitor the area next rainy season and see if that fixes the problem. No pressure to hire them or spend big $$, just good advice. Couldn't have asked for more. Highly recommended- this is real service!"

"Samuel is the best. We had water bubbling in the ceiling (never a good sign), and he was able to help us find a contractor to remove and replace the smallest part of the ceiling needed to address the leak. He was honest, prompt and most importantly - did a great job. Thanks Sam!"

"We had a second story deck that was leaking water into the garage. We got 4 companies to come and give us a quote.  Two of them were cheaper but they seemed as puzzled as we were about what to do and could not guarantee from future problems. The other company suggested rebuilding the entire deck and was way out of budget. Ryan from Monarch Custom Coatings came with a sample that had several layers to waterproof the deck - we were very impressed that he was very knowledgeable and has a lot of experience with this type of work. He and his crew worked very hard, always professional, prompt, courteous, and our deck looks amazing now. We were so happy with them that we hired them again to redo the garage floors. We have had bad experiences in the past with contractors, so we know that finding a good, reliable, and honest one is very hard and rare. We highly recommend Monarch Custom Coatings!"

"J&I Home Design was great to work with. The initial salesperson explained everything very well and their pricing was very competitive. The design and installation teams were great, coordinating everything. including the HOA application. The installation was done in one day as advertised. The county inspection passed without any issues and the system is now working as expected. Their technical support has also been excellent. Would recommend this company to family and friends."

Basement Waterproofing FAQs, answered by experts

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.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

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.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.
