The company describes itself on its website as a small family-owned business with over 15 years of experience in the sealant industry. A recent Google reviewer described a project to stop rainwater entering the interior through fixed windows and wall panels of a historic mid-century modern home on the National Register of Historic Places, along with replacing two 4'x8' fixed windows with broken seals. That reviewer said Justin Talalaj and his crew solved the problem using methods and materials acceptable to the CT State Office of Historic Preservation, and wrote "No more rain!" even after several months and numerous very strong rainstorms. A 2022 Google customer said Justin and his team came out to seal up their building, were on time and fixed the issues they had. **Strengths:** - Historic-home leak work — a recent reviewer described stopping rain through windows and panels - Leak stopped — a recent reviewer wrote no more rain after months of storms - An on-time visit — a 2022 customer said they were on time ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - A recent Google reviewer described work to stop rainwater entering through the fixed windows and wall panels of a historic mid-century modern home _(confidence: high)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2taVGFqRTFSSGxDYW5ob09FRkpUMlJUVTJZek9YYxAB!2m1!1s0x0:0x92f074d7a3c22726!3m1!1s2@1:CAIQACodChtycF9oOkZTajE1RHlCanhoOEFJT2RTU2YzOXc%7C%7C?hl=en-US) — “5★ Project involved: 1) finding methods and materials to prevent rainwater from continuing to enter the interior space thru stationery windo…” - A recent reviewer wrote "No more rain!" after several months and numerous very strong rainstorms _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2taVGFqRTFSSGxDYW5ob09FRkpUMlJUVTJZek9YYxAB!2m1!1s0x0:0x92f074d7a3c22726!3m1!1s2@1:CAIQACodChtycF9oOkZTajE1RHlCanhoOEFJT2RTU2YzOXc%7C%7C?hl=en-US) — “5★ Project involved: 1) finding methods and materials to prevent rainwater from continuing to enter the interior space thru stationery windo…” - A recent reviewer said the methods and materials used were acceptable to the CT State Office of Historic Preservation _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2taVGFqRTFSSGxDYW5ob09FRkpUMlJUVTJZek9YYxAB!2m1!1s0x0:0x92f074d7a3c22726!3m1!1s2@1:CAIQACodChtycF9oOkZTajE1RHlCanhoOEFJT2RTU2YzOXc%7C%7C?hl=en-US) — “5★ Project involved: 1) finding methods and materials to prevent rainwater from continuing to enter the interior space thru stationery windo…” - A recent reviewer said the job included replacing two 4'x8' fixed windows with broken seals _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sCi9DQUlRQUNvZENodHljRjlvT2taVGFqRTFSSGxDYW5ob09FRkpUMlJUVTJZek9YYxAB!2m1!1s0x0:0x92f074d7a3c22726!3m1!1s2@1:CAIQACodChtycF9oOkZTajE1RHlCanhoOEFJT2RTU2YzOXc%7C%7C?hl=en-US) — “5★ Project involved: 1) finding methods and materials to prevent rainwater from continuing to enter the interior space thru stationery windo…” - A 2022 Google customer said Justin and his team were on time and fixed the issues they had _(confidence: medium)_ - [Google Reviews](https://www.google.com/maps/reviews/data=!4m8!14m7!1m6!2m5!1sChdDSUhNMG9nS0VJQ0FnSUNXNUwtYnp3RRAB!2m1!1s0x0:0x92f074d7a3c22726!3m1!1s2@1:CIHM0ogKEICAgICW5L-bzwE%7C%7C?hl=en-US) — “5★ Justin and his team came out to seal up our building.
