"Our experience with Tullo's Home Improvement was good. Mike was very willing to work with us and take the time out of his schedule to meet with us a few times before we made a decision. After all the work was done, we realized that we made the right decision. Work was completed and very professional; once the work was done you couldn't even tell, except for a very nice new roof. Everyone at Tullo's Home Improvement that we have had contact with during this project was very pleasant, understanding and respectful. This was definitely a great project with the help of Tullo's Home Improvement."

"It went well! I expected it to take a long time to get it picked up, but I called for the bag to be emptied on Friday and they were here Saturday! I am already filling it up again. (We have a MESS from the storm and need to finish the kitchen before this weekend's company coming in from out of town.) I have already called them to request my bag be emptied on Friday, and they have me on the schedule! I can't believe the customer service is so great! This is not a regular dumpster company. I have a dumpster delivered last summer and they gouged my driveway. What a nightmare it was to get them to pay for the driveway to be fixed. NEVER AGAIN! It's BullBag only for our future needs."

Basement Waterproofing FAQs, answered by experts

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

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.

It is better to have a crawl space that is tailored to the outside temperature, your needs, and the season. For example, it is much better to have a vented space when it’s very hot outside and your AC bills are sky-high. Conversely, when the temperature drops and humidity rises, it is almost always better to have your vents shut and covered if possible.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.
