- LPLloyd Pratsch5 days ago5.0Honest, competent company. Installed a whole house generator and a water heater for me at a very competitive price. A distinguishing feature of this company is their knowledge. A well led company. Do not hesitate to solicit a bid. They may not be the lowest price: it's a sure bet they will not be the highest price. If you consider competence in your evaluation, this firm will be your top choice. Competence has real value, sometimes immediately, always later.
- PHPatti HouckMar 19, 20265.0Alfa Group did a great job installing my Generac Generator for my home in Fairfax, VA. They were really knowledgeable and easy to work with. The crew was organized and efficient. We feel much better knowing our home will have reliable back-up power during outages which happens a lot in our neighborhood in Fairfax. I would recommend these guys to anyone in Northern Virginia!
- WSWilliam StilwellJan 17, 20264.0Interior remodeling involved structural and finishing. Overall huge job that resulted in new look for bathrooms, family room, main stairwell and laundry. This was a rescue effort to correct a previous contractors unscrupulous plans and substandard work. ALFA Group's super effort resulted in continued contracts for additional work including kitchen flooring and full garage remodel. High satisfaction from their lead in addressing all details.
