## The honest read

Harmony Home Improvement describes itself on the BBB as an exterior remodeling company doing roofing, siding, windows, doors and decks, and its website says it has 25 years in business.

A recent customer who hired the company for siding, windows, a roof and doors said the project, signed in September and promised by Thanksgiving, was still not done going into April. That customer said a hole was cut into the new roof for staging, that 43 triple-pane windows were ordered with 2x4 frames for a 2x6 structure, and that a single worker was assigned to install 43 windows and 4 doors.

In 2025, a roofing customer said the 50-year warranty was never registered and the roof leaked during a rain; that 2025 customer later said the roof was being repaired by someone other than Harmony. In a 2024 review, a customer said a bay window arrived 2 inches too big, that the installer cut into the header to fit it, and that a building inspector said an engineer needed to be involved. In a 2024 review, a customer whose house was sided in late 2023 said it looked great, but that five months after promising to fix an upside-down door handle and a window casing, the installer had not come back.

A 2025 customer said the company installed a new roof and skylights and was clean, professional and on schedule. In a 2024 review, a customer said John gave the estimate and Carlos and his team put in a new deck and a frame for a trellis. In a 2022 review, a roof replacement customer said Dennis arrived with estimates drawn from satellite images and gave one page laying out options by roofing brand and warranty, with a price for each. In a 2022 review, a customer who needed only two windows replaced said John K came out to measure, and that Igor wore shoe protectors and worked until 7:30 on a Friday night.

Connecticut lists its home improvement contractor registration, HIC.0604200, as active, held by Harmony Home Improvement.

**Strengths:**
- A clear roof quote — a 2022 customer got priced options on one page
- A new deck build — a 2024 customer said Carlos and his team built it
- Roof and skylights — a 2025 customer said the job ran on schedule

**Concerns:**
- Unfinished exterior job — a recent customer said window work ran over 20 weeks
- Unregistered roof warranty — a 2025 customer said it was never registered
- Bay window header cut — a 2024 customer said the installer cut into it
- Unfinished small fixes — a 2024 customer waited five months for a return
- Missed quote appointment — a 2023 customer said nobody showed up
