"After hurricane sandy in 2012 a lot of people in Brooklyn and  Long Island got flooded a lot of home owners received flood damages or  lost their property due to Hurricane Sandy... I am living on Cony Island Seagate  area at that time I was home with my Family and how a remember the water came up to my house and flooded my basement and first floor of my house... I was very scared and desperate.... We basically lost everything at the first and basement floor...
We have received some help from FEMA like every homeowner in that area  but the rest was huge loss from our pockets...
We found structureline based on recommendations and we started to do renovation...Nicholas the General Manager helped us out to apply for a small loan so we could begin the  renovation...We needed to do a complete  house renovation ....
They took off the walls  in the basement and 1st floor, they did mold disinfection, replaced all drywall's, wiring, boiler, windows, doors, siding etc..
They did remodeling on the master bathroom from the first floor and kitchen, they did a wonderful job...We love their new engineered Hardwood floor and the new design of the bathroom with the big bathtub and shower cabinet ... The price we spend ed was a little higher than we were   expected because we did some design work in the living room and Kitchen but for sure it worth it....If Someone will ask me for a recommendation for sure I will recommend Structureline because they helped me out at that time ....Thanks"

"We bought a house in an area with a high water table and discovered flooding and moldy basement walls only days after moving in. Having to rip out a finished basement to waterproof and then refinish was a pain, but worked exactly as advertised. After mold remediation, installing a french drain, battery backed sump pumps, discharge pipes, and structural reinforcements, we finally had a comfortable, dry, and fully usable basement. No musty smell, dry concrete slab and foundation walls. I would hire A-1 again for waterproofing any time."

Structural Engineering questions, answered by experts

You need to hire a structural engineer when building or modifying any component with a structural load in your home. Common situations where you would need a structural engineer include home inspections when buying or selling a home, investigating possible issues with your foundation, beams, load-bearing walls, or chimneys, breaking ground on a new home or structure on your property, and renovating an old part of your home that could threaten any structural integrity. Home additions and bump-outs also require an engineer.

Yes, all states require structural engineers to carry the proper license, with specifics determined by each state. You can use Angi’s state licensing tool to confirm that the structural engineer you’re considering holds the required licensing to tackle your job. Hiring an unlicensed structural engineer will not only cause issues with permits but it could also lead to an unsafe building. The cost of a professional, licensed, and experienced engineer is well worth the investment.

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.

You should pick steel for your new support beam for a few reasons. While steel is more expensive than other materials, such as laminated veneer lumber or glulam, it offers the following benefits:

  • Fire-resistant

  • Unaffected by pests

  • Longer-lasting

  • Stronger against water damage (when galvanized against rust)

The costs depend on the type of wood, labor, roofing material, permits, and whether additional storage or enclosed walls are included.
