"We had our basement waterproofed by Baker's. It's been bone-dry since. We did have one piece of equipment fail within a month of the installation, but it was a third party dehumidifier that was just a dud I guess, no fault of Baker's. I texted the project manager about it on a Sunday. I expected a response the following week. He got back to me within the hour. The equipment was removed and replaced within a couple days. Everything great since. I would highly recommend Baker's, but specifically our project manager Nathan Goddard and the head guy on site Daylan. Can't remember his last name, but he's got a long beard and did a great job. Thanks to both of them and the rest of the guys."

Structural Engineering questions, answered by experts

Most lenders and homeowner’s insurance companies don’t mandate a structural engineer’s inspection, so in most cases, it’s not required. However, it’s a good idea to have one done anyway to ensure you know what you’re buying. You can use the report to carry out repairs after closing or even to negotiate the sale price before closing.

Through proper drainage solutions and compacting the foundation soil.

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?

No, beams are the primary load-bearers for flooring or roofing systems, and they distribute the weight of the structure to your foundational supports, while joists bear far less weight and distribute their loads to the beams. Beams are usually thicker and longer, and they have support posts or foundation walls beneath them for support.

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.
