Get matched with top excavation pros in Spring City, PA

"Michael was an awesome excavation professional. He is super personable and knowledgeable. Our newly purchased property was a bit of a wetland mess. Michael proposed a plan, gave us a very reasonable estimate and got right to work. We are very satisfied with the job, as our children now have a dry play area and the excess water on our land is being routed through a beautiful stone trench. We highly recommend his services!"

"Three Mountains came and did everything perfectly. They went above and beyond and were very courteous. I will definitely hire them again."

"Will work with them again!"

"Wes, is very professional and up front with his assessments. He has completed a 1/2 dozen excavation projects on my property and I was very satisfied with his workmanship. I will continue to use Wes for future projects."

"Very professional. Easy to work with."

"Luis and crew took a dilapidated wall and recycled all material in the installation. Came out great! He's also completed other concrete and retaining wall work for me and my company. Highly recommend!"

"Hired them in spring 2026 for a boulder ramp and grass seeding (about 360 sq ft), roughly $6,500 total. Two issues with the work. The topsoil they filled has since settled into a low spot deep enough that it's hard to push a mower across ? a grading issue that affects everyday use. And the grass they seeded was dead by early summer, within months of the install. They came back out and agreed to fix it by reseeding. I took that as standing behind the original work, so I was surprised when they sent a $400 bill for it ($250 labor, $150 seed and straw) ? essentially full price for a brand-new seeding job that size. I offered to pay the $150 for materials and asked them to cover the labor as making good on the install. I never received a reply after 10 days. The project price was reasonable, but the finish quality and the after-the-fact service didn't match it. If you hire them, get grading and finish expectations in writing up front."

"We hired the Davis remodeling company in June to rid our property of a tremendous amount of yard debris. Larnell was quick to respond and came out promptly for an estimate. He did an amazing job, which was not easy on an extremely hot day! Estimate was reasonable and would definitely recommend! He is also a very nice and professional person!"

"It went very well done in a professional manner will have done continuously and also did other maintenance"
