"I recently had All Pro Remodeling renovate my bathroom and complete a few other projects around my home, and I was very satisfied with the results. From start to finish, they were professional, punctual, and reliable—qualities that were hard to find with previous companies I had contacted over the past three years. What really stood out to me was their commitment to ensuring everything went smoothly. They brought all their own supplies and coordinated with me to align their schedule with the delivery of materials I had ordered. The communication was excellent, and the quality of their work was exactly what I had been hoping for. I will definitely be reaching out to them again for any future projects."

"Good work in general; our basement no longer sees water for over 3 years now, which is the most important thing. But there were some real issues: The biggest issue is that USW did not adhere to local electrical codes, and did not arrange for a final inspection of the project. So we didn't find out that it wasn't to code until years later, and now it's a big hassle and minor cost to fix and get the permits. Ask your local gov yourself what you need to do for permits and inspections; don't rely on USW! USW said they would seal any foundation cracks found along the way; they didn't do this until I bugged the warranty dept about it (but they did do it eventually). USW sent someone out for the "annual checkup"... over 2 years after the install. It's a good thing they (eventually) did, because they discovered the backup battery wasn't charging. Now I know to check this stuff better myself. Prices also vary wildly and are kind of negotiable (I'd give more detail but I'm out of space)"

"I hired Allegro to repair a wooden fence. They also bid on, and completed, a refinishing of a wooden deck. I was VERY happy with their work, and with their customer service! Their communications (via email and smartphone text) were complete, providing a detailed estimate of the work, as well as letting me know when the work would be scheduled. Their pricing was favorable as well, especially considering the quality and knowledge of the work needed. I recommend them and will be happy to use them again for similar projects!"

Basement Waterproofing questions, answered by experts

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

Crawl space encapsulation can make repairs more complicated, particularly if you have plumbing or wiring surrounding your crawl space area. Additionally, some home designs benefit from the additional airflow that crawl spaces with vents provide. Vents are no longer an option after encapsulation. Always talk to your crawl space contractor to ensure the pros outweigh the cons before investing in the installation.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.
