"We worked with Ali (sales manager) and Tony (project manager), who took the time to design a project that made sense for our property and our budget, made a number of suggestions and recommendations and were never pushy or tried to "sell" us on something. The crew really went above and beyond to provide top quality workmanship and overall we were in very good hands. Highly recommended!"

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

I am a single woman and we all know that many contractors like to take advantage of the lack of knowledge one might have in this area.   I interviewed many contractors for my project and found most to be substandard (to say the least) to my needs.  I found Bernal Construction from the time I first contact them to be very professional. Their Project Manager, Louise Williams is on top of her game from beginning to end.   It was a delight to work with her on this project.  She made sure that every thing was on track with this project which was delightful, since I was not in town for most of this remodel.  I knew I could depend on her. The owner, Raul Bernal is not only a great craftsman but insists that every detail of the project be up to his standards, which are high.  Both Raul and Louise are detail oriented and insisted that the job was perfect before giving their final blessing and handing me my final bill.  And even though the final payment was made, every time I call with a minor issue, they have been right here to correct.  I have felt very safe and secure not only with them but with their whole team of craftsmen. Thanks for inviting me into your family and for all the hard work!  GOOD JOB ALL, and I love the end result.

I purchased a big deal for this service and it worked out good. I just did not really jell with the designer so I did not use them. I did not like his ideas and did not like how they threw out the dollar amount for the project without knowing what I wanted to do. They are good, but it just did not work for me.

Basement Waterproofing FAQs, answered by experts

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.

Water damage always poses a primary risk of mold and mildew, but growth is not guaranteed. The chances of mold developing depend on several factors, including the severity of the damage and how quickly the area is cleaned and dried. To prevent mold, you must act quickly—ideally within the first 24 hours. Clean up all water and thoroughly dry the affected area. If the damage is extensive, you were unable to address it immediately, or you suspect mold has already started to grow, it is best to assume it is present and hire a professional mold inspector or removal expert to assess the situation.

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