Q: How can you tell if a crack is structural?

• <div><p>Foundation cracks that are 1/8 inch wide or less, aren&rsquo;t uneven across the gap, and don&rsquo;t continue widening over time are usually just normal settling cracks and don&rsquo;t suggest structural issues. Horizontal cracks and stair-step cracks on foundation walls, any cracks that continue widening, are wider than 1/8 inch, or where one side juts out beyond the other, are often indicative of structural damage.</p></div>

Q: How much weight does a 4-inch concrete slab support?

• <div><p>A 4-inch-thick concrete slab can support around 4,000 pounds per square foot if a contractor reinforces the slab with rebar, while that same slab without reinforcements will support closer to 1,000 pounds. For the purposes of a patio, 4 inches in thickness without reinforcement should suffice unless you&rsquo;re installing heavy kitchen equipment or a hot tub on it. In those cases, reinforcing your slab and sticking with 4 inches of thickness should provide plenty of strength.</p></div>

• <div><p>Provides expert analysis, ensuring safety and compliance with building codes.</p></div>

Q: What factors affect assembly costs?

"I had an experience with Neponset Valley Construction. They did work about three years ago. I would tell others that they're more for exterior jobs than they are interior jobs, the work is kind of shoddy. The price was the reason we went with them. "

"The team was great! Do to the fact it was a hectic period in my life, I needed most of the communication to be done over e-mail which they did. The quality of work exceeded my expectations. The unit is on the 10th floor
and build staff made a point to tell me how respectful the team was to them and to others in the building. This group made what could have been a stressful experience, an experience where I did not have to think about the details of prepping the unit for sale.
