Buzz and Bayaraa installed my condenser, and they did an outstanding job—professional, efficient, and friendly. Everything was coordinated seamlessly, from scheduling with Jen to my conversations with Ali, Rachel, and Maria. Everyone I interacted with went above and beyond to make the process easy and stress-free. I couldn’t have asked for a better experience. Highly recommend TopTec!"

"I initially hired HDH to help improve our laundry room work area. He removed an old cement sink, installed a replacement, relocated the washer/dryer and installed cabinets. Andrew and his team had all the skills needed - electrical, plumbing, carpentry - to complete the job quickly. I hired them again to paint a new exterior door, install floating shelves, and replace a broken faucet. I'm glad to have finally found a reliable and great to work with handyman. We look forward to working with them again soon."
