Customers say: Quality work

"Was having a potential home inspected for structural integrity. Spoke to Bob on the phone a few times. Since the home’s basement primarily consisted of a giant crawl space, I was told Don would do the job. Ultimately, the day before the scheduled inspection, I couldn’t get ahold of Don. Bob said Don was “feeling sick,” so the job was off. Frustrating, but a blessing in disguise because we ended up going with Colonial Restorations (the home was built in the 1800s). Colonial Restorations, LLC is the “go-to” for older home inspections and repairs. Tom was amazing (his son Brad is soon to take over the business)! They were both prompt, professional, and thorough. Very pleased with their work and thorough report/estimate. Colonial Restorations, LLC PO Box 868 Fiskdale, MA 01518 508-735-9900"

"In renovating our beach cottage in Warwick, RI we found the roof needed structural work. Building inspector required a structural engineered plan. Adam was easy to communicate with. He was timely with his plan and follow up inspection. He was also available by text and phone for questions during the project. He was great to work with!"

"After an unusual situation arose at my home, I was concerned about the possibility of structural damage caused by drilling and new construction at an adjacent lot. After receiving a recommendation for Veitas Engineers from a trusted source, I called and scheduled an appointment. I am so thankful that I did. I continue to be impressed with the amount of time that the two engineers spent at my house, closely inspecting the exterior and interior. Within days, I received a 16-page detailed report which included drawings, photographs, recommendations, and action items. I was so pleased when I saw that the action items were categorized as structural and non-structural, that is, that the engineers included items beyond my actual structural concerns. I used the report when working with a contractor to follow up on the recommendations and action items. The contractor was impressed with the quality, clarity, and scope of the report. I am so happy that I chose Veitas Engineers!"

"The guys from Three Masons showed up and were already setting up when I was told to expect them. I talked with the guys a bit on the work to be done and showed them the different locations for fixing the clapboards on the house. The quickly took care of the issues and everything has been great since. One thing that had been happening in the past when a windy storm came through the area that the clapboards would shake and make a noise. All of that got fixed with the work they did. They then went on to fixing up the molding around my front door which had rotted and install the extension setup needed for my storm door. They were quick and everything was installed nicely. We did a quick tour around after the completed all the projects and I paid them the final payment. I was very happy with the work that was done."

"I wanted the top courses of a chimney to be replaced. An incompetent mason botched the job totally. Masonry and More came to the rescue. They set up scaffolding and finished the job professionally and quickly. It looks great and was done at a very reasonable price."

FAQs for engineer structural projects in Andover, 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.
