Customers say: Terrific value

"Jack and his crew were thorough, professional and courteous throughout the entire waterproofing project for the basement, which included outside drainage work to better direct water away from the house, and the foundation repairs that were needed. He provided a detailed estimate and explained all facets of the project. Jack also provided additional recommendations for repairing the house gutters and downspouts. The home was built in the 1940's and the basement would flood following rain. Since the repairs, three rain storms within five weeks, each with over 3 inches of rain, have occurred and the basement waterproofing project was immediately tested. It has remained dry!"

"I was so happy the job was done quicker than I expected. It seems that lately there's a long, long wait for anything to get accomplished. The foundation is perfect for the gazebo I ordered. Yes, I will remember this company and if I need any other outside work I will definitelly hire them again. Very satisfied."

"Tony the owner of Torres Contracting gave me the best price to redo my driveway in blacktop and with a full paver border plus walkway. Pavers were Cambridge brand which is the best out there. He even repointed my stoop and fixed all the cracks for free. He has a great crew that knows their stuff. A+++"
