"When it rained my basement would get 2-3 inches of water. Tim and his team redirected all of the drain pipes (5 in all), reshaped the slope of the land surrounding my house, planted grass seed, and left the yard spotless. Now my basement is drier than Arizona in mid-July. These guys are pros, they finished in a day. It was a pleasure to see these men work! Their price was more than fair. You can't go wrong with DIGGS! Thank you, Tim!"

"Fausto and his team were great! I would have no hesitation in using them again. I had the attic space of a two-family building insulated with blown-in cellulose. I had already used Tigasi Home Improvement for a smaller Rockwool basement ceiling job and they were very reasonable in price, thorough and clean so I turned to them for this project. Again they gave me what I thought was a reasonable quote for removing old insulation, sealing gaps and then insulation, and Fausto explained the process well. He was very patient and understanding with my tenants' concerns, as access was via a drop down ladder in one unit's hallway. I also wanted an extended platform for storage in the attic and they were able to sort this out for a reasonable price.The team kept the job site extremely tidy and they were pleasant throughout. I would not hesitate to use Tigasi gain for another project. Plus I found them to be just really, really nice guys! A before pic and some after here."

"Was able to schedule a free consultation immediately and they looked through the basement to talk through possible mold issues. Turned out we didn’t have a mold problem but he answered all of our questions and was very kind!"

Basement Waterproofing questions, answered by experts

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation.
