We focus on all kind of projects, big or small. We do your traditional Landscaping such as cut grass, trim bushes/trees, pull weeds. We also work on bigger projects like creating new back or front yards and patios, and all kind of cement work. We work all year around and do our best to give the customers the best affordable price out there. We shovel during the winters and paint all year around, as well as much more.
"We do not recommend Hernanadez Landscaping. After at least 3 requests to for a written estimate, including the night before the project (we had to call for the arrival time), it was never provided. Red Flags! Jerry claims he sent it via the Angi app, and that he isn't given any personal contact information. However, he had previously asked for and gotten my personal email. When he first came to give an oral estimate, we liked the crew and agreed that they would install a walkway that matched the pavers of a connecting walkway, remove some trees and a brush pile, and clean the patio. When they arrived to start, we were told they didn't have the matching pavers. When we spoke with Jerry on the phone, it seemed he wasn't entirely sure which job was ours. At this point we cancelled the walkway project but asked him to do the other part of the job. The next thing we knew, the crew was packing up to leave. Jerry took no responsibility for the problems. One star is for the nice crew."

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."

FAQs for engineer structural projects in Waltham, MA
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.
