In October 2026 a Google reviewer wrote that William was the first general contractor they had ever hired, that they had been nervous about paying a lot of money to someone they didn't know, and that he captured their ideas in the finished job. Alvarenga's Empire Renovation is a Hartford renovation company that says it has been in business for five years and lists a service area across Hartford County towns from Farmington to South Windsor. In August 2026 a customer hired it for frame work on a bay window; once William started, he explained that rot and old wood meant the frame could not simply be repaired and a new window was needed. That reviewer called the price reasonable even after the change. A June 2026 customer had new garage doors installed and the crumbled floor area of the garage repaired, and wrote that the work was done within the time William Alvarenga said it would take. In March 2026 a reviewer wrote that the whole project, done with permits, took about two weeks from first contact to finish. In May 2025 one customer described a new porch with railings, new screens for a screened-in porch and a bathroom vanity. Another May 2025 reviewer had the company do a complete garage renovation, trim, molding and staining around a family room ceiling and skylight, and cabinet work in a laundry room and half bath. A third May 2025 customer had five thresholds rebuilt and the cellar stairs rebuilt to code. In a July 2024 review, William and his team replaced a broken window and repainted a portico and garage door in two days, and also filled gaps in the portico with foam and replaced a porch light they noticed needed it. Alvarengas Empire Renovation LLP holds an active Connecticut home improvement contractor registration, HIC.0699137, per the state registry. On Google it has a 5-star average from 23 ratings.
William did an excellent job. He was the first general contractor I ever hired and I was a little scared since I was paying a lot of money to someone I didn't know. He surpassed all of my expectations and did a great job and was able to capture my ideas and vision into a well done job. I would recommend and I've been recommending people to Alvarenga's Empire Renovation any time I can.
I needed some frame work done on a bay window and the price was reasonable even after William started the job and explained why he couldn't just repair the wood, due to rot and old wood, and I would need a new window. Great communication and the work was completed in a timely manner. Sorry I haven't had time to take pictures of the new window but it looks great.

Alvarenga's Empire Renovation did a fantastic job installing new doors for our garage and repairing the crumbled floor area of the garage.
