Bortolotti Construction Inc

Bortolotti Construction is a Marstons Mills excavation and septic contractor that's been doing site work on Cape Cod since the mid-1980s — full septic installs and repairs, water main and sewer line work, land clearing and demolition, with 30 employees on staff today. Robert J. Bortolotti is listed as president; the company describes its staff as OSHA-certified. The reviews on file run mostly positive: customers describe a responsive team that fixed septic problems at a competitive cost, and a 2025 review specifically credits the crew with correcting a job another contractor had botched, saying they explained the work and kept the customer informed throughout. General praise for professionalism and fair pricing on excavation and municipal waterworks jobs shows up across several other reviews going back to 2022. The record isn't spotless, though. An October 2025 review described a nearly $30,000 septic installation where the backfill used was rocky and full of debris rather than the clean fill quoted, the yard wasn't properly regraded afterward, and water has been pooling against the house foundation since — with the reviewer saying a follow-up attempt at regrading (one worker with a shovel) didn't fix it and further correction was refused. That's a serious, specific complaint about exactly the kind of job — septic and grading — this company is hired for. BBB carries an A+ grade for Bortolotti, though it's not an accredited business there, and its BBB file shows no complaints or actions — that channel simply hasn't picked up the Google complaint above. Given the mixed signal, it's worth asking pointed questions about backfill material and post-install grading before signing a septic contract here, even with the otherwise positive word of mouth on smaller excavation and repair jobs.
