We're a Land Surveying business located on Long Island. We specialize in a full range of surveying services including: title surveys, boundary surveys, topographic surveys, and site plans. We are able to complete land surveys in a shorter time frame and at a more competitive price because we utilize the latest in equipment/technology and are very diligent in our research practices.

"We hired scalice to do a survey of our new home. They sent workers that were new, unsupervised, and did not speak English. The workers broke huge branches off of about 9 ever green trees that were 30+ years old. The company even agreed that the new workers did not properly complete the survey and only offered a small discount on return - no one called, no one showed any compassion. We now have lost much of the privacy these trees provided. I would never use this company again."

Amoia Cody Architects brings to its clients a philosophy in design that emphasizes the creation of environments for the individuals they serve. As architects, our first job is to listen. Architecture is about appropriateness. It is important that building, interior space and landscape are integral to place and context. Architecture is about Process not Style. No two building projects are the same; each requires a solution unique to the client, the program, and the site. It is the role of the architect to uncover the nature of each project and reveal its form. We are a registered architect in NY, LEED accredited and a member of the AIA and NCARB. For over 15 years we have been involved in numerous projects varying from wood frame houses to precast concrete office buildings, interior renovations to free standing towers, design competitions to physical construction and solar detoxification facilities to The Museum of Modern Art. One of the things that separate us from other architecture offices is our personal attention to our projects. We attend to every detail and meet our clients by coming to you and spend time discussing your needs. We also make ourselves available evenings and weekends as required. Another important aspect of our work is the way we work with our clients. We present multiple schemes and work with you to find exactly what you are looking for. We never pull another project out of a drawer and make it your project. We thrive on challenges and appreciate clients who ask questions.

FAQs for engineer structural projects in Spring Valley, NY

You should replace floor joists as soon as you see clear signs of structural trouble—sagging floors, wide wall cracks, uneven door frames, wet or rotting wood, persistent squeaks, or windows that no longer latch. Tilted or sinking supports in the crawl space are another red flag. If you notice any of these signs, call a pro right away to keep your home’s structure safe.

If the joists are exposed from below, a pro can swap them out without touching the finished floor above. In an unfinished basement or crawl space, you’ll often see the joists and can easily reach them. When insulation, subflooring, or finished flooring blocks access, the crew must remove these materials before repairs can begin.

Sistering allows a pro to reinforce a cracked or undersized joist without tearing up the entire floor. The contractor slowly raises the frame, then fastens a new joist snugly against the damaged one to share the load. When done correctly, sistering restores full structural strength and keeps the floor level without the cost of a complete replacement.

Floor joists installed correctly in a stable environment can last for 100 years or more, often outlasting the house itself. However, termite damage, moisture, leaks, and other problems can significantly reduce a floor's lifespan. For instance, if the floor is exposed to consistent moisture, you'll likely need to replace the joists every 20 to 30 years.

Homeowners' insurance covers floor joist damage resulting from sudden and accidental events, such as fire, windstorm, or water damage from a burst pipe. It will not cover repairs resulting from gradual deterioration, poor maintenance, or termite infestations. Review your insurance policy and consult your provider to verify the conditions that guarantee full coverage. Doing so ensures you are fully aware of your responsibilities and can plan your repair work with complete confidence.

Floor joists are essential structural components that provide a stable foundation for your home. They directly transfer the weight of floors, furniture, and occupants to the foundation, ensuring stability and a safe living environment. Without these robust beams, the structure would face compromised load distribution, leading to potential safety hazards and costly repairs. Proper installation and maintenance are crucial for long-term durability and safety.
