It's important to ensure that the foundation of a house is constructed and maintained properly to guarantee its stability and safety. In earthquake-prone areas like California, poorly positioned homes have frequently collapsed, while those built on Sure Safe Foundations have remained undamaged.

"This team arrived for work in the morning, and was complete by lunch. Outside wall repairs on MidCentury Modern, and full assessment to bring house up to modern seismic codes. Great feedback to close out, plus a solid warranty. These folks specialize in crawl space homes and keeping them solid."

"Fantastic!!! I cannot speak highly enough of the guys and gals at Berkley Construction. After dealing with some, we'll say, less than competent construction companies, these guys were a god send. Organized, communicative and so easy to deal with right from the start, they made every step of the process so much easier and more smooth than it could have been otherwise. You should at the very least include them in your bid gathering, as I think they will blow you away with their competence, something that is sadly rare in this field."

A DUIN-IT Roofing & Construction, Inc. of Valley Center, California, provides expert contracting services and specializes in roof repairs and home renovations.

"We recently completed a second floor deck project on our home in Encinitas which included a full solid waterproof deck replacement, TimberTech, railing and other improvements. This project was made more challenging given the age of the home and state of some of the materials based on where we live closer to the ocean. Rob, Adam and team were incredible every step of the way, including communication and professionalism. They were able to work around challenges, come up with cost effective and creative solutions and generally keep us informed about the various parts of the projects as we moved along. They took extra measures to keep the working area clean during the entirety of the project. I would definitely hire this company for any future improvements to our home. Thanks guys!"

Basement Waterproofing questions, answered by experts

If you notice standing water under the deck after rainstorms, you may need a drainage system to efficiently move this water. You do not want standing water to rest against your foundation or against support posts for the deck, as this could cause significant structural problems over time. Make sure the area has proper grading, too.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Yes, basement insulation needs a vapor barrier due to its susceptibility to moisture seeping in from the outside of the house. You should install a moisture barrier before you install insulation or purchase insulation that comes prebuilt with a moisture barrier to avoid water damage in your insulation and costly mold and water remediation expenses. 

Mold and mildew are always a primary risk with any water damage, but it’s not guaranteed that mold will grow. The chances of mold growth are dependent on many factors, such as the severity of the damage and how quickly the area was cleaned up and dried out—that’s why responding to water damage immediately is imperative. If you suspect you have mold and mildew growth, you should talk to a local mold removal expert .

The easiest methods for waterproofing your basement include installing a gutter system to direct excess runoff away from your foundation and grading the soil away from your home to pull water away from the concrete. In some cases, these methods alone can be enough to eliminate water intrusion and moisture problems in your basement. If you have excessive rainfall in your area, though, you might need to employ more complicated solutions, like installing a French drain and a dehumidification system inside.
