Marco Polo Home Builder has been building homes & doing renovations all over Massachusetts with a great combination of skills-building knowledge, craftsmanship, and professional project management. Over the years, we understood that construction is about wood, bricks, and family. We take our job thoughtfully because we know that a home is the most sanctified place for a person. We value our clients' needs and work with our crew and subcontractors to prioritize them. We aim to make your dream project a reality and hope to be on this journey with you.

"We recently completed a gut reno and second story addition. After engaging 10 different contractors, MP was the most communicative, interested, flexible and competitively priced. MP has a large in-house team of experts that work efficiently and adapt to the home owner’s needs and preferences. The employees worked 6 days a week and took great pride in their work. They were personally invested in our project and wanted to make it the home of our dreams. The team includes an amazing designer, Nataly, who helped with selecting finishes. The onsite foreman, Adriano, demonstrated expertise and kindness. Seichelle and Marco did an excellent job with operations, ordering materials and problem-solving. We have been back in our home for 10 months. Anytime I have an issue, Seichelle and the team have addressed it. They have gone above and beyond what is expected. We could not be more pleased with our project. We strongly recommend MP for your next project!"

FAQs for engineer structural projects in Westborough, 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.
