"Gregg did a fantastic job repairing our basement foundation, and at a very competitive price. He and his excellent crew showed up on time every day, worked quickly and efficiently, and did a great clean up job. He was with them from start to finish, unlike most contractors who just show up in the morning to drop off their workers. Gregg is an old-school craftsman who obviously takes great pride in his work, and heâ s also someone who thinks outside the box. His company motto is â Exceeding Expectations,â and thatâ s exactly the experience we had. Weâ re totally satisfied with the job he did, and would not hesitate to use him again. Happy to give him our very highest recommendation!"

"Alex, the owner and lead contractor was a pleasure to work with. From start to finish the process was seamless. The waterproofing process was explained as well as the benefits from performing the work. Alex was personable, professional and knowledgeable. The pricing was very fair and competitive with the highest quality of workmanship. "

"Tim explained the project details in advance and how this should alleviate basement flooding. Tim and crew, excavated to below slab on 2 sides of house per plan; repaired cracks and holes in foundation, applied waterproofing and perimeter drainage with pump. Backfilled and leveled work site and seeded grass. Crew was professional and hard working. First rainfall few days later showed everything working perfectly."

"Eric the consultant inspected the job site took the measurements he needed and gave us an explanation of how the work was going to be handled. He also offered a discount and scheduled our project for the following week. When the day came the crew arrived on time and went right to work. We will use them again in the future for our pool deck. Overall a great bunch of people and a greater service."

"As a realtor, I found Rich from Expedient Environmental Solutions while searching for a client who needed mold remediation. He and his crew did an excellent job at a fair price. They finished on time and left the home clean. So, when I was looking personally to have basement waterproofing (interior french drains and sump pump) along with radon mitigation, I received 3 quotes, of which theirs was the most comprehensive plan, and again not the highest quote overall. They finished the work ahead of schedule by bringing four workers the second day, were respectful throughout and left the area reasonably clean. I'm confident that my days (and nights!) with the shopvac and flooded basement are finally over, and grateful they stand behind their work for a full year. Good contractors are hard to find. Glad I found them. Thanks and I highly recommend!"

"Fausto and his team were great! I would have no hesitation in using them again. I had the attic space of a two-family building insulated with blown-in cellulose. I had already used Tigasi Home Improvement for a smaller Rockwool basement ceiling job and they were very reasonable in price, thorough and clean so I turned to them for this project. Again they gave me what I thought was a reasonable quote for removing old insulation, sealing gaps and then insulation, and Fausto explained the process well. He was very patient and understanding with my tenants' concerns, as access was via a drop down ladder in one unit's hallway. I also wanted an extended platform for storage in the attic and they were able to sort this out for a reasonable price.The team kept the job site extremely tidy and they were pleasant throughout. I would not hesitate to use Tigasi gain for another project. Plus I found them to be just really, really nice guys! A before pic and some after here."

"We had a great experience with Westside Building and Restoration, Inc. Initially, we called Westside to look at our front and back porch roofs. Alan advised that the front porch only need very little minor repair, to correct the drainage. And the back roof would need considerable more. I was afraid to hear what that would cost. I was able to do my own research prior to committing and Alan's cost to repair the back porch roof was right on par and a little better. The team arrived on time from the onset, finished the job without delay and went over all of the repairs. With that being said, I asked Alan to do a few more minor repairs such as installing a window and repair the hinges, wood work on the carport doors. Buckey took the extra step to put vinyl on the top portion of the doors to prevent future wood rot. Buckey and Chris was so kind, wonderful to talk too and so professional. My neighbors stopped by to see the final jobs and was so impressed, now Alan has new customers. The Westside office team always responded to my text or emails if we had questions. The Westside team worked around our schedule. in the end, we are so happy Alan and his team made this process run smoothly. The final projects turned out great!!!"
