# Luis – Assembly & Indoor Environmental Services **Trade:** Handyman · **Languages:** English **Rating: 4.0/5** (low confidence) — from 5 reviews across 1 sources. 100% of sentiment-scored reviews read net-positive. Last 6 months: 3 reviews, 0 negative. ## The honest read Two very different kinds of calls end up with the same guy: on Thumbtack, Luis's business, branded Atlas Biosolutions - Indoor Environmental Services, pulls nearly identical praise whether he's diagnosing mold on a bathroom ceiling or bolting together a patio swing. The Revere, Massachusetts operation is one year old and rated 4.7 from fifteen Thumbtack ratings, with 93% of those coming in at five stars. The mold work is the more detailed side of the record. In a March 2026 review, a homeowner described Luis tracing a bathroom ceiling mold problem to poor ventilation and condensation on a colder section of the ceiling, then treating the surfaces and recommending ventilation and insulation fixes to keep it from returning. Another March 2026 review, from an apartment mold job, notes he used safer products instead of harsh chemicals and explained the moisture conditions behind the growth rather than just wiping it away. On the assembly side, reviews from March and May 2026 describe him putting together a patio swing with canopy, a dresser, and an e-trike, with recurring mentions of speed: replied immediately, came when scheduled, finished early. One customer called the price for the patio swing fair and reasonable and said the finished piece matched the manufacturer's photos exactly. One note for balance: of the fifteen ratings on his Thumbtack profile, one came in at a single star, with no comment attached to explain what happened. If you're weighing a mold or air-quality concern against a standard assembly job, the reviews suggest he treats both the same way: figure out the cause, not just the symptom, and explain it along the way. Given the one-year track record, it's worth asking directly about his experience with a job similar in scale to yours before booking. **Strengths:** - Mold diagnosis — explains moisture and ventilation causes, not just symptoms - Furniture assembly — quick turnaround, described as finishing early and cleaning up - Fair pricing — one reviewer called the patio-swing cost fair and reasonable **Concerns:** - One low score — a single 1-star rating among fifteen, no comment given ## Claims & citations Every claim below is backed by real evidence rows — uncited claims are dropped in code before publication. - One year in business, based in Revere, Massachusetts. _(confidence: medium)_ - [Thumbtack](https://www.thumbtack.com/ma/revere/handyman/luis-assembly-indoor-environmental-services/service/566797581907394562) — “This Thumbtack profile, branded 'Atlas Biosolutions - Indoor Environmental Services', is Luis's Revere, MA business rated 4.7 from 15 review…” - Rated 4.7 from 15 Thumbtack ratings, with 93% at five stars. _(confidence: high)_ - [Thumbtack](https://www.thumbtack.com/ma/revere/handyman/luis-assembly-indoor-environmental-services/service/566797581907394562) — “Thumbtack: 4.7★ from 15 ratings” - [Thumbtack](https://www.thumbtack.com/ma/revere/handyman/luis-assembly-indoor-environmental-services/service/566797581907394562) — “Thumbtack star distribution: 93% 5★ · 7% 1★ (of 15 ratings)” - Diagnosed poor ventilation and condensation as the cause of a bathroom ceiling mold problem, treated the surfaces, and recommended ventilation and insulation fixes to prevent it returning. _(confidence: high)_ - [Thumbtack](https://www.thumbtack.com/ma/revere/handyman/luis-assembly-indoor-environmental-services/service/566797581907394562) — “We had mold starting to appear on the bathroom ceiling and walls, and Luis from Atlas Biosolutions helped us figure out the cause.
