We specialize in basement and crawl space waterproofing. Our experienced team is dedicated to providing effective solutions to keep your basement dry and free from water seepage.

"About 8 years ago, after a brutal series of flooding rains, we started getting water in our finished basement. Eventually over the years it became a huge problem whenever there was significant rain, which happened frequently. In August 2018 we unfinished the impacted part of the basement and obtained quotes for a repair. Seepageseal was by far the most responsive and most reasonable. They did not press us into a large scale expensive solution. They installed a vapor barrier and drain tiles, in addition to a sump pump. They brought in an experienced team that quickly, cleanly and efficiently completed the installation. It is now April 2019 and we have endured numerous rain storms that have flooded our neighbors basements. Their solution has proven 100% successful. We highly recommend this company."

Structural Engineering questions, answered by experts

The process of hiring a structural engineer starts by finding reliable professionals in your area and comparing quotes from at least three of them. From there, you can narrow down your selection by asking some leading questions:

  • Do you have experience working in my specific area?

  • Do you have professional indemnity insurance?

  • What will your structural report cover?

  • Do you charge a flat fee for a structural report or by the hour?

  • How long have you been in business?

  • Do you have a list of customer references?

The essential difference between an architect and an engineer is that architects typically focus more on the aesthetic design of buildings, although not without consideration for the structural integrity of the building. Engineers focus more on the structural, technical, and practical aspects of whether and how an architectural design can be built as drawn. You may need to hire both types of professionals if you’re designing and building a new home.

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.

In framing, studs are placed at 16-inch intervals to coincide with the typical spacing of wall materials such as drywall or plywood. This spacing is called "on-center" and is necessary for maintaining structural stability and efficient use of materials. The 16-inch spacing also helps to distribute the weight evenly across the building's structure. For those looking to cut material costs and improve energy efficiency, 24-inch stud spacing can be employed through a method called "advanced framing". This requires careful planning and adherence to local building codes to ensure structural integrity.

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation.
