I have relied on Alcantara Contractor for many jobs over recent years including 2 bathroom remodels, HVAC update, and a build out of a basement office. In addition they have quickly come onsite to address time sensitive issues with plumbing and heating systems. In every instance they have been great to work with, and delivered great results.

Given our unique set up, I reached about to Carlos for guidance on replacing this appliance and he was able to help us in both the planning and execution of this small kitchen project. His expert team was able to get this installation done in a day, even when it required more work than we originally planned.

We were very happy with the work provided by Alcantara Construction. They were fast to respond and give an estimate for exterior painting of our two family home. In addition to this the house needed exterior carpentry work and shingle replacement which they were also able to do, making the whole process very convenient. They showed up as planned and worked quickly and efficiently. They were respectful of our property and finished in a timely manner. We would be happy to use their services again and would recommend them to others.

We had an extremely positive experience with Alcantara Contractors. A large part of our basement had remained unfinished for years, and now it is completely transformed into a beautiful and usable space that we are very happy with. The team was professional and polite, stuck to the budget, and didn’t pressure us to add things at a higher cost. They paid great attention to detail, and took care of things that I didn’t even notice. They finished the work earlier than I expected, and cleaned up after themselves perfectly. Highly recommended!

Carlos and his team promptly delivered a detailed scope of work with a reasonable quote. Within days of approval, work began and was completed in just a couple of days. The workmanship was outstanding, the job site was kept clean, and Carlos provided daily progress updates.
When the garage doors needed a post-completion adjustment, I notified Carlos and he came out quickly to resolve the issue.
What sets Carlos's team apart:
1. Fast response — he returns calls quickly
2. Quick, fair quotes — reasonably priced every time
3. Rapid start — work begins within a day or two of the go-ahead
4. Excellent execution — completed quickly with top-quality workmanship
I'll definitely be calling Carlos and his crew for future projects.

During our recent blizzard it became clear to me that my wife and I had hours of back breaking work ahead to dig us out! We were not looking forward to it! Then I contacted alcantara for assistance. Carlos immediately got back to me with pricing and timeframe of when his team could be there. They were awesome to deal with! Dug as out, cleared off our cars, porches, driveway and steps. We didn’t have to do a thing! Remember to contact Alcantara for any needs you may have renovations, construction, snow removal, etc. Alcantara is the best!!
