# Vulcan Basement Waterproofing

**Trade:** Waterproofing / Foundation · **Address:** Stamford, CT · **Phone:** (877) 885-2268 · **Website:** https://vulcanwaterproofing.com/?utm_source=gmb&utm_medium=organic · **Languages:** English

**Rating: 2.4/5** (low confidence) — from 3 reviews across 6 sources.

## The honest read

Vulcan Basement Waterproofing's website lists residential basement waterproofing, French drain installation, sump pump service and installation, crawl space waterproofing and basement crack repair. The company says it has been in business 79 years and offers free estimates.

In a 2022 review, a customer said they never connected the discharge pipe, so the sump pump was pouring water behind the wall and causing mold. That 2022 customer also said they drilled through asbestos tile and mastic, leading to thousands of dollars of asbestos abatement, and that the project manager did not return phone calls over three weeks.

A 2022 customer said the end result was good and on time, but that communication was complicated early on, with several assessments of the scope of work that were not fully aligned. A 2022 reviewer called Geoffrey Dahill very professional and recommended the company for basement needs.

**Strengths:**
- An on-time finish — a 2022 customer said the end result was good

**Concerns:**
- A disconnected discharge pipe — a 2022 customer said water ran behind the wall
- Unreturned calls — a 2022 customer said the project manager never called back
- Scope assessments — a 2022 customer said early assessments were not fully aligned
